2009-2012 Analysis of mobile phone battery industry, development prospects and investment risk prediction report

2009-2012 Analysis of mobile phone battery industry, development prospects and investment risk prediction report

2009-2012 years, the development prospects of mobile phone battery Laptop Battery industry analysis and investment risk forecasts, China's battery companies a total of 1017, the vast majority concentrated in the Guangdong province, other provinces and cities of battery manufacturers are few and most manufacturers produce both mobile phone battery cells also produce other products. In addition, despite the small number of Chinese enterprises with foreign cells, but its total profit is the highest among all enterprises. Foreign mobile phone battery capacity of strong corporate earnings, while the profitability of local enterprises to be improved. With China's lithium-ion battery technology to mature, the global lithium-ion batteries in China began to shift. Foreign-funded enterprises have to adjust its global strategy to China as the focus of its global mobile phone battery production base.


The world's leading mobile phone battery Sanyo Electric Company in Beijing, Tianjin, Panasonic, Sony in Wuxi to establish their own production base in Presario NX9010 South Korea only to open the battery into the Fujian, the U.S. investment in the power plant g in Xianyang, China's lithium-ion battery industry, the cost of the main advantages of have been gradually eroded, domestic battery with low price as the small business market, the main direction, industrial R & D investment intensity of weak changes in the status quo as soon as possible. Mobile phone battery manufacturers of China's major distribution and production capacity are relatively concentrated, mainly in South China Shenzhen BYD, BAK, Shenzhen, Huizhou TCL, Huizhou Desai, energy, new energy, Dongguan, Shenzhen B & K and so on, mainly in North China, Tianjin power of God, Harbin Guangyu, Presario 2500(compaq 2500 battery) Henan Huanyu, etc. There are in Xiamen, East China Baolong, Shanghai Panshi, Fujian Scud and so on, a total of more than 30 large scale of mobile phone battery manufacturers, accounting for the majority of China's mobile phone battery industry capacity, in addition, other small-factory is hand - are just countless. Concentration of Longgang District, Shenzhen, BYD Co., Ltd., confidant group, BAK Battery Co., Ltd., well-known lithium battery manufacturers become the largest mobile phone Li-ion battery production and export base. From the ownership point of view, China's lithium-ion battery production enterprises mainly foreign-funded enterprises, state-owned enterprises and collective enterprises in the industry as a whole accounted for a very small proportion. Size from a technical point of view, China's lithium battery technology and products are close to advanced world standards, the size of further expansion of BYD in Shenzhen and Tianjin power of God is to enter the international top ten of the column. The next few years, with BYD, BAK, B & K, force God, Universal, Guangyu the continued expansion of Presario 2100(compaq 2100) production scale, China's lithium-ion battery industry will maintain a very high average annual growth rate. China's mobile phone can monitor the market sold more than 150 million, the actual sales of close to 200 million, the total number of mobile phone users in China has more than 600 million. With a cell phone to configure two batteries, China's mobile phone battery has annual sales of more than 298.26 million, the general mobile phone battery, the average price of 90 yuan, the Chinese mobile phone battery industry, with annual sales of about 270 billion yuan. An average annual growth rate of 20%, is estimated by 2013 China's mobile phone battery market will reach sales of more than 700 billion yuan. China is a big power consumption of mobile phones, mobile phone battery consumption is also increasing every year. And because cell phone features a strong, quality requirements of mobile phone batteries are growing, super-capacity, long battery 319411-001 standby time, and become the new darling of mobile phone battery products.


In 2009, in the user security awareness rising trend of domestic brand, the battery will be subject to market of all ages. In this study a large number of thorough consultation report on the basis of market research are mainly based on the National Bureau of Statistics, Ministry of Commerce, the State Industry and Information Technology Ministry of China Battery Industry Association, China's trade research network, domestic and foreign-related magazine publications, as well as basic information mobile phone battery and other public research institutions and provided large amounts of data, combined with research in Price Waterhouse's battery-related businesses on the mobile phone field surveys on China's mobile phone battery status and prospects of development of the industry, market F4812A competition and the situation, profitability and business development, investment strategy and risks of early warning, development trends and planning proposals, such as an in-depth research and focused on analyzing the prospects for mobile phone battery industry and risk. The report reveals the potential of the mobile phone battery market demand and potential opportunities for strategic investors to choose the right investment opportunities and corporate leaders to do strategic planning to provide accurate market intelligence information and F4098A, F4809A scientific decision-making basis, while bank credit departments also have great reference value.

World Renewable Energy Committee Chairman Interview (b)

World Renewable Energy Committee Chairman Interview (b)

■ Chinese Characteristics --


The Chinese government's full support to work closely with civil appeal echoed to promote renewable Laptop Battery energy in China lead world growth rate.


Reporter: According to what you know, the world, which countries or regions in the use of renewable energy sources has the more prominent achievements? Their experiences which draw on China's significance?


Dr. Paltz: 5 years ago, Germany in wind, solar, bio-energy and other renewable energy development in the area was once the world. But now catching up with newcomer China, production capacity has exceeded that of Germany.


In China, the first thing I see is the Government to vigorously implement the new energy policy. China is second only to Germany's world, the second to the use of renewable energy development legislation in the country. Since 2006, the Chinese government for the new energy and renewable energy development policy, financial and economic have given great Omnibook XT1000 support.


Can not be overlooked is that China's non-governmental forces in this area also played a significant role. Chinese people feel that they need for renewable energy development, there are many areas of life are in the development and use of this new approach to energy. Therefore, renewable energy development in China is not only a top-down implementation, but also civil society as well as local residents are also bottom-up expression of this appeal.


As for the experience, and no one inherently has a certain experience. This is a new energy, there is a new development law. To economic development is also a new kind of boost power. One very important point is to give the community the development of new energy industry and create a lot of job opportunities. Pavilion ZT1100 China should be in all aspects of the development of new energy sources.


Reporter: Do you think in an international context, the field of renewable energy development What are the problems?


Dr. Paltz: Renewable energy in the most serious misconception is that there are technological obstacles. Currently in the world, renewable energy applications is full of vigor and vitality. Promotion is also non-existent technical problems, the current wind and solar photovoltaic technology is relatively mature. The application of the difficulties, mainly cost. However, if through the scale, resulting in economies of scale, the costs will be significantly reduced, thus much easier to promote them.


■ Looking to the future --


Held fast to the market law, attach importance to international cooperation in the development of China's oil Pavilion XZ200 companies and shoulder social responsibility mission and the national strategic interests, an energy revolution in the new world in the long way to go.


Reporter: China's renewable energy future, can you give some suggestions?


Dr. Paltz: First, we should be clear that renewable energy is the future trend of development. Now is not difficult to see that the development costs of traditional energy sources become increasingly expensive, while the cost of developing new energy sources become increasingly expensive. Renewable energy prices in the future we should be all the way down. Since this energy is stable, inexpensive, why not use it, not ring true trend of the times, but to do the opposite then? The law of market competition will make renewable energy more and more welcomed by the society. The Chinese government in the future, energy development plans should also give priority to the development of new energy and renewable energy. I support the Chinese Government's current practice.


Secondly, we should attach importance to the energy field of international exchanges and cooperation. For example, natural gas imports, I very much support the Chinese Pavilion ZT1000 government is now doing the work. The world's oil resources and the distribution of natural gas resources is uneven. To strengthen international cooperation and exchanges, can build a win-win situation, ultimately beneficial to the development of human society. At the same time, China is a big country capacity, but also the energy-power. Input of energy from abroad, not only to meet the energy needs of the community, but also for development of renewable energy to gain time advantage for the promotion of the financial crisis of the global economic recovery and to a certain extent to solve the employment problem, but also play no small role.


Third, China's oil and natural gas development is promising, but the development of renewable energy sources the government also needs more attention. China's current energy consumption structure, coal accounted for nearly 70%, then there are oil, gas, and hydropower. Natural gas and oil are non-renewable fuels, and the use of these fuels into the atmosphere each year Breath billions of tons of CO2. Therefore, in the world is concerned, in the adjustment of economic structure involves a question of the relationship between F3172A mankind, is to develop low-carbon economy, providing low-carbon energy. China's energy use is now mainly coal, and coal use the main problem is to clean. Therefore, clean coal technology in China should also be taken seriously.


Fourthly, with regard to the development of nuclear energy in the world that there is dispute. Leakage incident at Chernobyl in 1986 brought an unprecedented catastrophe to mankind, also shows that development of this energy source there is a big risk.


Reporter: For the traditional energy sources such as the China National Petroleum Company, in the future, the use of renewable energy development opportunity you have any suggestions?


Dr. Paltz: Yesterday I met in a hotel in Beijing to participate in several wind energy research conference in Baku, the oil experts, and discussed with them to energy development issues. We know that the Republic of Azerbaijan capital of Baku is the history of the world's oil major oil base, the world's oil industry was started from Baku. Since then, Baku, has been the F2299A "oil city" known for. I have learned to talk with them, Baku now also focus on renewable energy development, wind, solar, hydroelectric and other areas for investment.


For the development of an enterprise, the resources, technology, capital and human resources support for all aspects of complex factors are very important. We have to look long term, because some things may now be more expensive costs for enterprises willing to invest, but in the future will become the core needs of society.


The opportunity exists, we must seize the opportunity. Enterprises should be diversified energy investments, and should not put all of them are concentrated in a single energy. In addition to oil and gas, but also can develop a variety of new energy industrial chain. Presario NX9000 Not only to focus on domestic market, because China's large population, resources are limited. The vast overseas market business leaders should be the focus of development planning business in the new period.

World Renewable Energy Committee Chairman Interview (a)

World Bank China Renewable Energy Development speed leader in the world - World Renewable Energy Committee Chairman, Dr. Wolfgang Paltz interview.


Wolfgang Paltz (WolfgangPalz), Dr.


Wolfgang Paltz (WolfgangPalz), Dr is the world's renewable energy Laptop Battery commission (WCRE) Chairman, Global Bioenergy Partnership Committee members, honorary members of the Council of the International Solar Energy Society, the European Union Council. From 1977 to 2002 served as executive officials of the European Commission, responsible renewable energy development and planning from 2000 to 2002 served as member of the German Parliament Energy Commission is responsible for Germany's 2050 energy strategy planning.


Mr. Wolfgang Paltz Federal Republic of Germany has been awarded meritorious service medal, in the United Kingdom is considered a pioneer wind and biomass energy in Europe were given awards, wind and solar Prize Award.


Wind power to achieve three consecutive years, doubling the size of


This year in October, the World Renewable Energy Committee Chairman, Dr. Wolfgang Paltz once again invited to attend the Beijing "2009 China International Energy Forum," Omnibook XE3 and delivered the keynote address. After an interview with the always concerned about China's renewable energy development in the world's energy experts.


■ Debate too fast --


China's renewable energy development is not too fast, and impressive, and vigorously promote renewable energy development is a wise move, and the only way.


Reporter: Dr. Hello. Thank you for your many years of the world's renewable energy sector and the enormous contribution made by China's sustained attention. I ask, do you think the status of China's renewable energy standard in the world is in what position?


Dr. Paltz: China's renewable energy capacity for F2024A development is enormous. China has become the world's second largest country in installed capacity of wind power, solar cell manufacturing superpower, solar energy heat utilization, mainly the use of solar water heaters and the annual account for more than half of the world's total, ranking first in the world. In the wind energy field, China wind power capacity added this year is expected to rank first in the world. In fact, some statistics have indicated that China's wind power, solar photovoltaic cells, small hydropower and other strengths are in the world.


With wind energy, for example, the world's leading wind energy advisory body - the Danish consulting firm BTM said at the end of this year, the world will produce 150 billion wind energy W, of which 22 million KW from China. By 2017, global wind power output to 700 million KW, and China by 2020, wind power output 100 million KW. Obviously, that time, production is likely to need more than the forecast. Because the current growth is so impressive, the growth rate even reached 100%, and thereafter can not be reduced F2024B to zero.


Of course, the field of renewable energy is not the only wind power. In the "2009 China International Energy Forum", I heard a very exciting lecture on small hydroelectric power stations. There are currently 300 million people rely on this power, China ranked first in the world. The small hydropower, apart from the Three Gorges water conservancy stations that large-scale water conservancy projects, China's entire territory for the balanced development is a very important form. Its development should not be confined in large cities. China's small hydropower as to promote throughout development has brought outstanding results to the world has set a good example.


In general, first of all, the rapid development of China's renewable energy and success. In wind, solar photovoltaic in China as the world's forefront. China can also provide many of the world economy, the price excellent renewable energy products, as well as some lower cost, but the quality is excellent, very competitive Omnibook XE technology.


Secondly, we have in the EU set a goal: By 2020, electricity generation from renewable energy capacity to account for 40% of the total generating capacity, we are now the ratio is 20%. That is a 10-year period, renewable energy generating capacity should double. This does not include nuclear power in Europe. And China, the development of renewable energy has created a miracle. China has done very well, with a good starting point. I think in the future, China may have to do better than in Europe.


Reporter: Renewable energy in the future society will be necessary for energy, and play an increasingly important role, which has become the consensus. But at present the field of renewable energy in China is developing rapidly, it was described that as being stepped on the accelerator. You agree with this view? Is not, as some people have said, this "too fast" development will lead to the risk of overcapacity?


Paltz Dr.: I totally do not agree with this view. With wind energy, for example, in the past three years, China has doubled every year. Some people think that "I have never seen a technology that could be so high-speed development, we should implement some of their control." F1739A I think the only problem is that in the development of wind energy at the same time easy to set up high-voltage transmission grid to transport wind energy, for example, from Inner Mongolia to the east coast. But now do not have enough high-voltage transmission networks. China is now up to 100 million KW per year of electricity output, which means that China will require enormous effort to build a grid system to the effective delivery and use of these energy sources.


It is noteworthy that, due to cost, it is now no right to use wind power to give adequate attention remains focused on priority construction of traditional coal-fired power plants. This is a problem. Although China's wind power development is still faced grid and technical problems such as bottlenecks, but we can foresee the future of wind power industry will have a more rapid development.


China should expand the use of wind energy. Because the energy consumption of China as a big country needs the energy. Pollution-free wind energy, and pure production in the territory of more than the cost of development of nuclear energy should be much lower. The question now is the construction of power grid system. The development of wind power is already fast enough, and now need to improve the problem is that the construction of wind power systems.


China this year is expected to increase 10 million KW of wind power, for the first time in the world primacy. Living in the United States second, OmniBook 6000 are expected 600-7000000 KW. We believe that as China's economic development as the development of wind energy is still in high-speed track speeding.


■ according to local conditions --


Renewable energy development as well as "people-oriented", China should be taking into account specific national conditions and actual conditions to develop and implement a scientific and rational, workable renewable energy development plan.


Reporter: China's large population, huge energy consumption. Renewable energy can meet the huge demand for energy in Chinese society? Do you think China's development of various types of renewable energy What are the advantages and disadvantaged?


Dr. Paltz: China's renewable energy development can fully meet the energy needs of F2019B Chinese society.


China's wind energy is developing rapidly attracted worldwide attention. Official data show that the total now has reached 12 million KW, estimated that by 2020, China will have to build capacity is estimated to reach more than 100 million KW.


China's hydropower resources, is also among the highest in the world. 2008 has been the development of power generation capacity is 172 million KW. In addition to large-scale water projects supported by the State, small-scale hydropower development on China's civil society is also very impressive.


China is one of the largest solar energy production. Solar water heaters used in the area is very common in China, the world second to none. But compared to China's vast territory, rich in solar energy, and now solar energy output is relatively small. Therefore, in solar energy development has great potential. China is now producing solar power are related to private enterprises, the State Government's support for less. However, private enterprises in this regard has been done a terrific job.


Many people think that in the future may compete with the oil and gas major renewable energy is biomass fuels, so strongly appeal to the Chinese F2019A bio-energy development. But they are easy to ignore a problem, there must be room to collect the development of biomass fuel materials. China because of the burden of carrying huge population, agricultural development must be given priority. Because we can not for the production of motor fuel and let some people go hungry. In any case, agriculture should be security, food reserves should be given priority.


Brazil is the world's largest ethanol producer and exporter. Land area, population is relatively small, and the government throw its weight behind the development of bio-fuels for them provided a good atmosphere. But in fact, we need to note that, in Brazil, only 1% of the area of agriculture for bio-fuels. Only 1%, rather than the entire country. So, I think you can within a certain region in China, the development of bio-energy, because China is not all areas are densely populated areas. However, we must ensure that the development of biofuels should not compete with food production. Last year, President Lula of Brazil came to China, with Chinese leaders on fuel ethanol imports from Brazil, the agreement was discussed.


In short, the vigorous development of renewable energy will allow China to become the world's most competitive countries.


Reporter: China's wind power generation regions are mostly concentrated in the F2019 economically less developed areas, such as China's north-west and north. Then we should be how effectively these can be used for energy consumption and large production capacity, the more economically developed regions?


Dr. Paltz: should strengthen the construction of wind power high-voltage transmission grid. The first is cost. In fact, China power grid construction, a lot of investment. China's production capacity this year, 100 billion W, but only 10 million KW was from wind. China is still a lot of energy investments for the construction of coal-fired power plants, because coal is still the main part of energy consumption in Chinese society.


Another issue is the use of wind energy technology. Because wind energy is not the law, its power sometimes up, sometimes down, while the usual habits of the people is stable energy resources. In Germany, people have succeeded in making wind stability. Thus, only about technical issues can be solved completely. Parts of Germany, 40% of its energy from wind. While Germany's land area is much smaller than China, but China's wind energy resources are far from rich. In addition, many wind power plants are not connected to a network, this also affected the use of wind energy Omnibook XT1500.

The new energy automotive battery industry prospects

The new energy automotive battery industry prospects

Shenyin published reports, promising policies to promote new energy Laptop Battery automotive batteries under the sector investment opportunities. Analysts believe that the next 3-5 years, Ni-MH battery HEV (hybrid electric vehicle) will remain the mainstream of new energy vehicles, HEV will PHEV (plug-in hybrid electric vehicle), EV (electric vehicle) co-exist for 10 years about. In the 3-5 years later, with the yield increase lithium iron phosphate batteries to bring the cost down, as well as the national network of charging stations gradual establishment of lithium iron phosphate batteries as the main driving force of the PHEV, EV will usher in a broad space for development. Analysts suggested concerns Keli far (18.20, -0.41, -2.20%), the torch high (11.85, -0.26, -2.15%), Shanshangufen (16.81, -0.22, -1.29%), Jiangsu Guotai ( 24.89, -0.09, -0.36%), Tibet Mining (24.34, -0.17, -0.69%).

Port Machinery benefit from the recovery in exports


Hai Tong Securities (15.00, -0.01, -0.07%) released a report that the Port Machinery Company in the third quarter results below expectations, Pavilion DV4000(hp dv4000 battery) as a whole reflects the status of the industry is hard to Sheng. Based on the market is widely expected fourth quarter, an increase of domestic exports turned positive in 2010, an increase of 10%, analysts believe that port machinery export-related companies will benefit from the warmer. Analysts said profit next year, Port Machinery Company expects an increase of -4.90% -0.00%. Warming by the stimulation of exports, the container demand is expected in 2010 will be better than 2009. Container production from access to production delivery order cycle is only 1-3 months, CIMC Group (11.42, -0.13, -1.13%) of the container business will be much improved next year, the company main business in 2010 to restore growth will occur to give the company "overweight" rating; Zhenhua container cranes Heavy Industries, the low orders in 2009. Container crane production cycle for a year or so, the company in 2010 container crane PM579A operations there may be 20% -30% of the decline, giving the company a "neutral" rating, the existence of investment opportunities may be more event-driven in large orders.


Gradual improvement phosphorus chemical industry needs


United Securities released a report that in September, China's phosphorus chemical products (phosphate rock, yellow phosphorus, phosphoric acid, phosphate, and phosphate) production are making a positive year on year and sequential growth of demand for downstream industries turn for the better, agricultural demand is gradually into the season.


September of domestic phosphate rock production 6.13 million tons, ammonium phosphate fertilizer production 1.688 million tons, two are single-month record high domestic production; phosphorus output of 91,000 tons, is also the maximum value during the year.


Phosphate rock production greatly increased, but prices stable; phosphorus prices started to rise since September, "11" restricted policy 367759-001 allows manufacturers to focus on the downstream stocking. Near the dry season in October, prices continued to rise. Analysts expect fourth-quarter seasonal phosphorus prices will rise 1000-2000 yuan / ton.


Phosphate fertilizer production began to enter the earnings season, the rest of phosphorus chemical products into the price of peak season. Phosphorus chemical industry as a whole the trend of improvement in profitability has not been formed, analysts on maintaining a "neutral" rating, the maintenance of Hing Fat Group (18.86,0.07,0.37%), "overweight" rating; fourth quarter of phosphate fertilizer business performance worth the wait, proposes a focus on six chemicals (11.63, -0.22, -1.86%).


Highlight the investment value of stock brokerage


Guotai Junan Post reported that since November, tape re-price PF723A the amount of Chai Sing situation. The first Sunday in November were 280 billion yuan turnover, November 6 is a breakthrough transaction volume of 3,000 billion; 4 since the fourth quarter, average daily trading amounted to 224 billion yuan, compared with average daily transaction volume this year is 5%; tape from the 2779 points, started, or has reached 14% at present, are far better than expected. In this way, four-quarter brokerage brokerage, underwriting and self-employed are expected to be exceeded expectations. In particular, need to focus on is the self-yield expected from three quarters of -6.1% to 15% -20%. In addition, China Merchants Securities IPO support for high-priced broker valuation, the performance of the GEM thickening of the effectiveness of broker-dealer is also very obvious.


From the trend point of view, this round of rebound, banking and insurance index has been the high point of one step from the previous month, while the brokerage index still 22.7% of the distance. Broker on the market flexibility better than insurance, but the trend is obviously weak. In the market and policy environment for a double to the good Pavilion DV1000(hp dv1000 battery) background, performance and valuation showed a significant increase space, requested a strong compensatory growth.

Li-ion laptop battery basics (b)

Li-ion laptop battery basics (b)

Application Notes


The above-mentioned two kinds of lithium batteries is a disposable Laptop Battery battery, non-rechargeable (charge time is dangerous!); The battery is not short-circuit between anode and cathode; not be too large current discharge (more than the maximum discharge current discharge); battery until it ceases to discharge when the voltage should be electronic products removed in a timely manner; run out of battery is not squeezing, burning and demolition; can not exceed the prescribed temperature range of use.


As the lithium battery voltage is higher than ordinary batteries or nickel-cadmium batteries, make no mistake when used to avoid damage to the circuit. Through the familiar model of the CR, ER can know the type and rated voltage. In the purchase of new batteries, be sure to buy according to the original model, otherwise it will affect the performance of electronic products.


Rechargeable lithium batteries


Rechargeable lithium batteries There are many, such as lithium - vanadium oxide batteries, lithium-ion battery and abroad, a newly developed lithium - polymer batteries. Here describes only the first two, focusing on lithium-ion battery.


Rechargeable lithium-ion battery is currently the most widely used mobile phone battery, but it is more "finicky" in use can not overcharge, over-discharge pavilion dv6000(hp dv6000 battery) (may damage the battery or make it scrapped). Therefore, the protection of components or the battery protection circuitry to prevent damage to expensive batteries.

Lithium-ion battery charging very high, to ensure that the termination voltage is within 1% accuracy, at present the major semiconductor factory has developed a variety of lithium-ion battery charging IC, in order to ensure safe, reliable and fast charging.


Now phone is a very common part of the phone nickel-metal hydride batteries, but the smart phone type is a lithium-ion battery. The proper use of lithium-ion battery for extended battery life is very important.


1. Lithium - vanadium oxide batteries (Li-V6O13)


Lithium - lithium vanadium oxide 342661-001 batteries for the anode, vanadium oxide as cathode, inorganic salt electrolyte composed of organic solvent. It features can be charged. With 2 batteries, for example, the lithium - vanadium oxide battery and lithium - lithium manganese dioxide batteries, and - compared with thionyl chloride batteries as shown in table 5.

From Table 5 we can see, due to lithium - vanadium oxide batteries rated voltage of only 2.8V, and the rated capacity is also small, so when compared with other two kinds of lithium batteries, its specific energy is minimal. The main parameters of such cylindrical batteries as shown in Table 6. As can be seen from Table 6, the number of charge cycles (cycle life) is not long, so this rechargeable battery soon replaced by a lithium-ion batteries.


2. Lithium-ion battery (Li-Ion)


Lithium-ion battery is currently the most widely used lithium batteries, which according to different requirements of electronic products can be molded into a flat rectangular, cylindrical, rectangular, and button, and there are several cells in series with the composition of the battery pack.


Lithium-ion battery rated at 3.6V (some products are 3.7V). When fully charged the termination charge voltage and 345027-001 battery anode materials relate to: the anode material is graphite 4.2V; anode material for coke 4.1V. Resistance of different anode materials are also different, slightly larger internal resistance of coke anode and the discharge curve is also slightly different, as shown in Figure 1. Commonly referred to as 4.1V and 4.2V Li-ion battery Lithium-ion batteries. The termination of lithium-ion battery discharge voltage 2.5V ~ 2.75V (battery factory operating voltage range is given, or given the termination of the discharge voltage, the parameters slightly different). Less than the termination of discharge voltage to continue to discharge known as the over-discharge, over-discharge of the battery will be damaged.


Lithium-ion batteries are not suitable for high-current discharge, over-current discharge will reduce the discharge time (internal temperature will produce a higher loss of energy). Therefore, the battery manufacturing plant gives maximum discharge current, in use should be less than the maximum discharge current.


Lithium-ion batteries have certain requirements on the temperature of the factory give the charging temperature range, discharge temperature range and the preservation temperature range.


Lithium-ion battery on the charge requirement is very high, it requires sophisticated charging circuit in order to ensure the safety of charge. Termination tolerance for the rated charge voltage accuracy of ± 1% (for example, 4.2V rechargeable PP2182L lithium-ion batteries, its tolerance of ± 0.042V), over-voltage rechargeable lithium-ion battery can cause permanent damage. Lithium-ion battery charge current should be based on the battery manufacturer's recommendations and demand for a limited flow of the circuit in order to avoid over-current (overheating). Commonly charge rate 0.25C ~ 1C (C is the battery capacity, such as the C = 800mAh, 1C charge rate of the charge current is 800mA). In the high current charge, often to detect the battery temperature to prevent overheating damage to the battery or produce an explosion.

Li-ion laptop battery basics (a)

Li-ion laptop battery basics (a)

Portable electronic products to the battery as a power supply. With the rapid development of portable products, all kinds of greatly increased battery Laptop Battery usage, and has developed many new battery. In addition we are familiar with high-performance alkaline batteries, rechargeable nickel-cadmium batteries, nickel-metal hydride batteries, there is in recent years, the development of lithium batteries. This article introduces the basic knowledge related to lithium batteries. This includes its characteristics, the main parameters, models of meaning, application and use for attention.


Lithium is a metallic element, its chemical symbol Li (its English name lithium), is a silvery white, very soft, lively and chemical properties of metal, the metal is the lightest. In addition to its application outside the atomic energy industry, can produce special alloys, special glass (TV screen glass used), and lithium batteries. In lithium batteries use it as a battery anode.


Lithium batteries are also divided into two categories: non-rechargeable and rechargeable types. Non-rechargeable battery known as the disposable batteries, it can only be a one-time chemical energy into electrical energy, electrical energy can not be restored back to chemical energy (or restore the performance of poor). The rechargeable battery is called secondary batteries (also known as batteries). It would be chemical energy into electrical energy stored in the use of time, and then convert chemical energy into electrical energy, which is reversible, such as chemical energy lithium batteries power the main features.


Smart portable electronics products require Pavilion dv9000(hp dv9000 battery) light weight and size of filial piety, but the battery size and weight compared with other electronic components are often the largest and most heavy. For example, I remember when the "Big Brother" is very "thick, heavy," while today's cell phone is so light. One improvement is the battery played a significant role: in the past is a nickel-cadmium batteries, lithium-ion batteries are now.


The biggest characteristic of lithium batteries is higher than the energy. What is the specific energy then? Refers to the specific energy per unit weight or unit volume of energy. With the specific energy Wh / kg or Wh / L to represent. Wh is a unit of energy, W is watts, h is the hours; kg is 1000 grams (weight units), L is liters (volume units). To give an example to illustrate: 5, nickel-cadmium batteries are rated at 1  2V, its capacity is 800mAh, then its energy is 0  96Wh (1  2V × 0  8Ah). 5, the same size Lithium - Manganese Dioxide battery rated at 3V, its capacity is 1200mAh, then its energy is 3  6Wh. Both the battery size is the same, then the lithium - manganese dioxide battery is a nickel-cadmium battery specific energy of 375 times!


1 5 nickel-cadmium batteries, weighing about 23g, while a 5 Lithium - Manganese Dioxide Battery weighs about 18g. 1 Lithium - Manganese Dioxide battery 3V, while the two nickel-cadmium battery only 2  4V. Therefore, when the battery using a small number of lithium battery (to reduce size of portable electronic products to reduce the weight of filial piety), and long battery operating life.


In addition, the lithium battery with a discharge voltage stability, operating temperature range, self-discharge rate is low, storage, long life, no memory effect and pollution-free and so on.


The drawback is that lithium batteries are expensive, so it is not yet widely used, mainly used in handheld computers, PDA, communications equipment, 396008-001 cameras, satellites, missiles, torpedoes, equipment and so on. Along with technological development, process improvement and production increase in the price of lithium batteries will continue to decline, applications will be more common.


Non-rechargeable lithium batteries


Non-rechargeable lithium batteries have a variety of currently used are lithium - manganese dioxide batteries, lithium - thionyl chloride batteries and lithium batteries and other compounds. This article describes only the first two of the most commonly used.

1, lithium - manganese dioxide batteries (Li  MnO2)

Lithium - Manganese Dioxide Lithium battery is a kind of anode to manganese dioxide as cathode, and a one-time use of organic electrolyte batteries. The main characteristics of the battery cell voltage is high, rated voltage of 3V (an ordinary alkaline batteries 2 times); the termination of the discharge voltage of 2V; than the energy of large (see above examples); discharge voltage is stable and reliable; a good storage properties (storage time 3 years), self-discharge rate is low (annual self-discharge rate ≤ 2%); Operating temperature range -20 ℃ ~ +60 ℃.


The battery can be made into a different shape to meet different requirements, it has a rectangular, cylindrical and button-shaped (button). There are also different cylindrical diameter and height measurements. Here are all the more 395789-001 familiar one # (size of the code D), 2 # (size of Code C) and 5 # (size of the code AA) batteries main parameters.


CR is expressed as cylindrical lithium - manganese dioxide battery; five figures, the first two that the diameter of the battery, the latter three, said with a decimal level. For example, CR14505, whose diameter is 14mm, height of 50  5mm (this model is generic).


Here we must point out that the same plant are different types of batteries may be some differences in their parameters. In addition, the standard discharge current value is smaller, the actual discharge current can be larger than the standard discharge current, and the continuous discharge and pulse discharge permit discharge current is different from the battery plant to provide relevant data. For example, Li Hing power produced by CR14505 gives maximum continuous discharge current of 1000mA, maximum pulse discharge current up to 2500mA.


The camera using lithium batteries are mostly lithium - manganese dioxide battery. Here the camera commonly used in lithium - manganese dioxide battery included in Table 2, for reference.


Button type (button) batteries smaller, its diameter is 12  5 ~ 24  5mm, a height of 1  6 ~ 5  0mm. Several more commonly used button batteries as shown in Table 3.


CR for the cylindrical lithium - manganese dioxide battery, the last four digits in the first two for the diameter size of the HSTNN-DB20 battery, the latter two with a decimal point for the height measurements. For example, CR1220 diameter of 12  5mm (not including the number after the decimal point), its height is 2  0mm. This model that is universal.


This button batteries commonly used in clock, calculator, electronic notebook, cameras, hearing aids, electronic games, IC cards, backup power supplies.


2, lithium - thionyl chloride batteries (Li  SOCl2)


Lithium - thionyl chloride battery is the highest specific energy of a current can be achieved 500Wh/kg or 1000Wh / L level. Its rated voltage is 3  6V, medium-current discharge with a very flat discharge characteristics of 3  4V (available at 90% of capacity to discharge within the flat to keep small change). The battery can be -40 ℃ ~ +85 ℃, within the scope of work, but in -40 ℃ ambient temperature when the volume capacity of about 50%. Self-discharge rate is low (annual self-discharge rate ≤ 1%), storage life of up to 10 years.


With a # (size of the code D) nickel-cadmium batteries and 1 # lithium - thionyl chloride battery than the energy to make a comparison: 1 # nickel-cadmium batteries are rated at 1  2V, a capacity of 5000mAh; 1 # lithium - Asia Sulfur chloride rated voltage of 3  6V, capacity 10000mAh, the latter than six times more energy than in the former Pavilion dv8000(hp dv8000 battery) Great!

Li-ion battery performance Xiangjie <

Li-ion battery performance Xiangjie <

Battery capacity. In order to pursue slimmer body, better Laptop Battery portability, the battery would have made sacrifices. Now with MP3 players can watch movies about 3 ~ 4 hours, music, 12 hours or so. Q2 marked as 50-hour endurance is to a very stringent conditions can be attained. For example, the song bit rate, the battery charging perfectly, sound off, volume, and so limited. Well, in order to use more time for everyone to talk about how "attended to" the battery.

Lithium batteries in the discussion, we must first understand the lithium battery is divided into two types: lithium batteries and lithium-ion batteries. Li-ion battery is the electronic watches and other products in the button batteries, in theory, can also be charged. But not only ineffective, but also easy to short-circuit, so generally are not allowed to charge. Later, after Sony's improved design materials, inventions lithium-ion battery. This is what we are now widely used in lithium batteries, security, higher, life expectancy longer. The following discussion of the lithium batteries, both PB991A lithium-ion battery.


1. How do I recharge.


Legend 1: The battery has memory, the first three charging must be filled, at least 12 hours! This argument refers to the nickel batteries. Nickel battery memory strong at the beginning will affect the use of activation is not sufficient. While lithium batteries have to activate, but it's easy, after 3 to 5 times the normal charge and discharge can be activated. There is no memory of its own.


 


Classic SONY gum battery


Classic SONY chewing gum battery, you can see a clear indication for the Ni-MH (nickel-metal hydride) batteries.


Note that for too long instead of charging lithium batteries will cause harm, so the vast majority of electronic products are charging protection function. When the battery is full, the automatic power off. We can not guarantee protection must rely on charging to PB994A live a precaution, we still do not charge the battery a long time As for the state. In addition, some parts of voltage instability, lithium batteries relatively poor resistance to volatility, longer recharge time, which means even more vulnerable.


2. When charging.


Legends II: running out of power as far as possible, preferably automatic shutdown recharge. It is also said that nickel batteries. As the nickel battery memory, so every time you can begin using photoelectric charging. Some people may remember, the early mobile phone charger there are still "discharge" of this feature. However, lithium batteries model does not apply to this rule, over-discharge of lithium batteries but harmful. In order to ensure the life of lithium battery, preferably a low power consumption when prompted to start charging.


Ni-Cd (nickel-cadmium) batteries


The first generation of rechargeable batteries, Ni-Cd (nickel-cadmium) batteries. There is memory and cadmium on the human body is lethal.


Say that a true story. I once went out to play, cell phones do not charge a timely manner, resulting in power completely used up. Can not be recharged back to PB992A power, and had to give customer service overhaul. This is because the battery voltage is too low, leading to excessive discharge, or even do not have the normal charging conditions.


PSP to use Li-ion (Li-ion battery)


3. In the use of precautions.


In recent years have continuously heard that mobile phone battery explosion thing. Light burned property, in serious cases even burn the user. As for the explosion culprit Well, that is the battery of (nonsense, have not heard of the motherboard can be an explosion!). This is because the lithium batteries in many materials in contact with water, after severe chemical reaction can occur, and release a lot of heat, resulting in fever, burning. Manganese dioxide lithium battery cathode, only a small drip can dip fever phenomenon. Lithium thionyl chloride batteries in contact with water in the generation of hydrochloric acid and sulfur dioxide, while releasing heat. To understand the reason, preventive measures is also very simple, as long as attention to water moisture on it. Do not have lithium batteries must remove the battery should be placed separately. Winter is coming soon, after returning from the outdoors must be careful not to MP3, mobile phones and other products remain on the clothing pocket. Condensation products both inside and outside will become very wet, dry and ventilated a timely manner. Even if the battery is no problem, but also 398876-001 may cause short circuit damage to the device.


Was the battery burned pants


Some guests may have to ask, you can charge while watching movies? This problem can not be generalized. Some products of the AC circuit and the battery circuit separate from the design, while the use of edge charge completely no problem. However, some will not be able, if the description does not specify, for security reasons, the best customer service bar or advice.


Lithium battery tips


Lithium battery is a lithium metal or lithium alloy anode material, the use of non-aqueous electrolyte solution batteries. Reflect the process as follows:


Li + MnO2 = LiMnO2 the reaction of oxidation-reduction reaction, discharge.


Lithium batteries can be widely used in recent years, although it, but it has a long history. The first one lithium battery is invented by the great inventor Thomas Edison. Because lithium metal is very active on the manufacturing process make high demands. Early use only in the aerospace or the military field, along with manufacturing process 337607-003 improvements, has been able to promote civilian equipment.

Laptop battery power-saving-oriented of the three major controversies

As the price of notebook batteries Laptop Battery are expensive "consumables", it triggered a lot of use of arguments.


With the increasing popularity of notebook computers, notebook computers on all aspects of the problems cropped up in various media on the largest number of arguments the proper use of laptop batteries, notebook batteries some articles say that the use of personal experience, while others claim expert guidance, all kinds of stories are, the argument number.


The author is also a regular laptop user, although not an expert, but with many years experience in the use of notebooks, the author through a friend recruited dozens of university students using a laptop Hp laptop battery, so that they talk about their experiences on the use of laptop batteries, coupled with its a little more experience, summed up what made available to everyone as a reference, hope to give everyone a little help.


1, the argument 1: the activation of a new battery


Point 1: before buying a new battery inside, there will be more than 3% of electricity, more than the battery inside the power exhausted, until the shutdown, and then re-use an external power supply charge. Charging time must be more than 12 hours, repeated three times to do in order to activate the battery.


Point 2: No, the battery for 10 hours of rechargeable battery to activate the activity of the normal charge-discharge method for activation.


Survey Results: The author investigated and 24 college students laptop users, 18 is the second point of view, and that such manner and does not charge the battery for future use can hurt, of course, to exclude damage to the natural elements. The author himself is also the case when the normal use of a new battery for up to two and a half hours, now two years past, the status of the battery is still good, still can reach more than two hours, so I have been satisfied.


The proposed method: I agree with the second view, based on Compaq Presario 2100 battery(compaq 2100 battery) available information indicates that the activation of cell work should be completed at the factory, and laptop battery factory with a capacity of some natural wear and tear in order to avoid damaging the battery. Activation of the battery should be in no circumstances to protect the circuit can be with its own lithium battery circuit protection circuit, the purpose of this piece of the circuit is to avoid excessive battery charge and discharge, generally filled with the battery after charging when the indicator light off , the battery can not be recharged into the electricity, and then you then plug the power plug to recharge the battery in the face of what use? Available from the battery can be seen on the status of the battery have any charge, another teaches you a simple way to be able to determine whether there during the battery charging, battery charging, when the phenomenon will have a fever, when the battery is full after one hour (power plug does not pull), you go try the battery to see if the battery is still warm not hot? The result is definitely cold, because the battery is not charging and discharging state certainly does not heat. Notebook makers at the factory will propose that a new battery Hp 319411-001 battery for more than 10 hours. This sentence may be generated for some users the wrong point of view first, the author of this opinion, should be taken into account that some notebook manufacturers a new user in the new battery charge when not fully grasp the skills, simply so that they can charge directly 10 hours, so this should be the business of expediency.


Second, the argument two: whether the external power supply unplug the battery?


View 1: Use an external power supply when the battery removed.


Point 2: Use an external power supply is not required to remove the battery.


Survey Results: Most students in the use of an external power source, will the battery removed, only a few use an external power supply when the battery is placed above, that the few brands are used by students in several international brand.


The proposed method: In fact, if the battery Hp F4812A battery is removed, the conflict focused on the use of an external power supply when the battery is charging to the issue. We should know that the number of charging and discharging the battery life is directly related to the general lithium battery set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially modified products, but 800 times, once for each rechargeable batteries a step forward to retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only increase the number of charge cycles, but will also cause overcharge. The second view is that the battery is full power on the computer in the use of an external power supply will not recharge. In fact, both views have their right side, but also the wrong place. Because it is only the views expressed by individuals is not very comprehensive, after I investigated, many notebook manufacturers are taking into account the vulnerability of the battery Hp F4809A battery , and the product added to the battery protection technology, and thus the corresponding different brand laptop batteries charging protection technology is different, like some large companies do very well in this regard, such as: IBM, Hewlett-Packard, Toshiba, Compaq, etc.. One of the most thoughtful consideration is that IBM, IBM's notebook computers can detect the battery discharge situation, ThinkPad notebook battery only less than 95% of the time will automatically recharge. This can play a very good protective effect on the battery, and now many other manufacturers have followed suit. So, like the battery, you do not have the time to use pull down, because only when the capacity less than 95% of the time it would charge. But even so, if you are a long time using your computer, or remove the battery


To compare the good, because the long-running laptop heat generated when the battery Hp F4098A battery will cause some damage. However, some other "little brand" laptop batteries, may not enjoy such treatment, because it has not done inside the battery protection technology. I like to use a certain brand of notebook computers, if the fully charged battery on the above, when using an external power supply was confirmed when the first charge about electricity, because the battery storage, will have wear and tear, can not reach 100%, while not 100% as long as , power supply connected to the charge. Each access to external power supply is equivalent to charging the battery once, although only a small charge will be the time. Therefore propose that we use when the machine according to their own circumstances, look at the laptop manual, choose whether to use an external power supply when the battery dell 4834T battery removed.


Third, the argument 3: How to correctly charge?


Point 1: The battery power should always be all exhausted, so that consumption of notebook computers to automatically shut down and then recharge, each must be filled.


Point 2: when the battery is very deliberately not to pay attention to, and use when I wanted to charge to charge.


Survey Results: Most students said that, unnecessary to the first view, as used in automatic shutdown and then charge, but dell 2834T battery also like the second point of view, it is free of charge. Are generally used when the battery needs charging when the computer prompted further charge, of course, prompts the time can be set, the default is to 3%.


The proposed method: In this paper the proposed method with the majority of the students is the same. In fact, regardless of laptop use nickel-metal hydride or lithium batteries, these batteries are have a memory effect, and nickel-metal hydride batteries with memory effect is very obvious, but equally there will be lithium memory effect, but its memory effect smaller than the nickel-metal hydride Bale . There is no memory effect on lithium to say, only exaggerated and irresponsible dell Latitude LS battery business conduct in advertising, is totally misleading. Well, since the battery has a memory effect, it should be noted when charging point, as far as possible and then run out of charge, but do not have to deliberately say must use the computer to automatically shut down, so that although there is no harm in using them (because the laptop battery has a charge discharge protection and automatic shutdown in general has not yet reached notebook battery discharge protection standards), but you do not feel so tired? In fact, less than 3% of the charge in this way is very good, memories will certainly be the effect, compared to natural wear and tear, it should be nothing. As for the second charge on the charge to the view, the author is completely disagree, and have already said, whether laptop battery nickel-metal hydride or lithium, which has a memory effect, if in this way then the battery life will be shortened.

Laptop battery maintenance to note what

What is the use of laptop battery maintenance of the taboo? Laptop battery Hp F3172A battery maintenance of the books in the end whether or not to pull, pull-out how to do that if a power outage? Laptop battery maintenance of good, if the maximum can use for how long? See below, it will know.


Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must be used in attention to some maintenance tips: Whether you use the notebook lithium notebook battery or Ni-MH battery, battery power as much as possible to the basic use to do after filling (capacity less than 5%), which is the best way to avoid the memory effect. In fact, the lithium-ion battery has some memory effect, but much smaller than the nickel-metal hydride batteries Laptop Battery Bale. However, attention is needed to carry out charging as much as possible to avoid too long, the general control within 12 hours.


Laptop battery battery life not by the length of the total use of time, but by the charge and discharge times to decide. Here is the importance of maintenance of notebooks. If the battery will always be loaded to a notebook instead of taking down, then even if the machine shut down and remove AC power, the battery would not have imagined, as has been maintained, as when fully charged state. Laptop battery because the battery in the integrated control circuit, so even shut down your computer when power is power. As one connected to AC power, the battery will begin charging, when turned on or off the power, your laptop battery Hp F2299A battery will be charged and discharged repeatedly, affecting battery life.


To do this, use an external power supply when the AC is best to unplug the battery, or laptop battery a long life of their implications in the hot state. To maintain the battery for the long term do not, please charge and discharge at least once a month to ensure that its activity. In the custody of the battery when there is a need for attention. At present, the vast majority of notebooks used in lithium-ion batteries do not use if a long time, often prone to the phenomenon of excessive discharge, may no longer Compaq Presario NX9000 battery be able to recharge laptop batteries. In order to prevent over-discharge, can be in semi-charged state to save in a cool dry place, and then every six months, and then to half of


In addition, the factors that affect battery life books also include the use of the environment temperature (below 30 ℃ proposed use), battery storage and battery temperature suffered shock size. Laptop battery in use after a period of time will be aging (how care is the same), concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled with capacity is also naturally declined. The laptop battery correction is an effective way to deal with aging batteries, a small number of laptop battery calibration software will be dedicated. If your laptop not have a dedicated discharge software, then the battery Compaq Presario NX9010 battery can be maintained in accordance with the following steps:


● Disable the screen saver;


● In the Windows Power Management power scheme will be set to "always open";


● In the Alert tab will be "insufficient power warning" is set to 10%, the operation is set to "no action";


● will be "a serious power shortage alert," set to 3%, operating as a "pending";


● the screen brightness to the maximum;


● confirmed that closed all the windows, and keep all the previous work of the data;


● confirmed that over 80% battery charge after the unplug the power and all external devices.


Discharge after the notebook will automatically shut down after the power plug for laptop charging, this process can be repeated 2 to 3 times to let the battery continuous low current discharge, which discharge status in our daily use is not possible Compaq Presario 2500 battery(compaq 2500 battery) achieved, the effect of the discharge and those dedicated basically the same software.

Notebook School - Science and the use of laptop battery guide

Advantage lies in its notebook mobility, while the battery Laptop Battery is to provide basic mobility. Batteries in notebook computers occupy a pivotal position, which is from the notebook of the benchmarks can be seen - no matter what kind of laptop is a comparison test, MobileMark an indicator of success are very important.


Here we will briefly explain how to scientifically and to use their own laptop batteries.


First of all, a kind of popular practice whereby the use of electricity in the long hours of work, many users will remove the laptop battery that this can extend the battery Hp Omnibook XT1500 battery life. In fact, the use habits to ensure a good premise, remove the battery module or not on battery life, and not much impact. For users who do not remove the battery needs to pay attention not to frequent Plug Power, which is due to appear inconspicuous short plug power supply, will generate the battery charging and discharging process, the frequent charge-discharge operation will shorten the battery life; while for the battery on the side of the users, the best time to time (about a month or so), it will be placed in the battery Hp Omnibook XT1000 battery recharge laptop computers, so that can help keep the battery in the best condition If the battery is idle for too long can lead to reduced capacity.


Second, lithium-ion battery, battery depletion is not necessary to conduct further charge that this is because lithium-ion battery is almost no memory effect. The so-called memory effect occurs in nickel-chromium batteries or Ni-MH batteries, these batteries do not fully discharged in the circumstances, will produce a kind of crystallization reaction, resulting in a temporary decrease battery capacity, if you want to eliminate the memory effect can be done several times the battery fully charge and discharge cycles, there is likely to come back to save the battery Hp Pavilion ZT1100 battery.


Another issue requiring attention is the use of the environment, although the mobile computing will encounter a variety of environment, but at room temperature to ensure the use of battery life, or there are certain advantages, too cold ambient temperature on overheating notebook computers will be harm. In addition, when using a transformer operation, the power supply from outside will only support the system operation, while charging the battery, so that the charging process of Hp Pavilion XZ200 battery charging more than shut down state operations slower, if you want to fast-charging, better carried out in the off state.


Some users complained that some of the battery capacity display features built-in reliability is not high, in fact, these products there is a special calculation of battery capacity chips. In general, the percentage of notebook computer batteries in the display still has a certain credibility, and should be noted that from time to time, it is best to do the battery calibration operation to correct the calculation of battery capacity chips may have errors. Calibration can be performed through two methods: unplug the external power Hp Pavilion ZT1000 battery supply, turn off power management in power-saving mode, and will self-discharge to shutdown your computer; the use of BIOS or in random calibration provided by the related software.

Laptop battery maintenance! How to do

What are the laptop battery maintenance mode? What is the use of laptop battery maintenance of the taboo? Laptop Battery maintenance of the books in the end whether or not to pull, pull-out how to do that if a power outage? Laptop battery maintenance of good, up to be able to use for how long? See below, it will know.


Laptop battery life is longer, often dissatisfied with the charge, or even show damage, if coupled with maintenance of normal laptop battery has not done enough good, even more accelerated pace of aging of the battery! Therefore, attention must be used in a number of maintenance tips. Whether you are using a notebook lithium batteries, or nickel-metal hydride batteries, as much as possible to the basic battery charge after the exhaustion (power less than 5%), which is to avoid the battery Hp laptop battery the best way memory effect. In fact, the lithium-ion battery has some memory effect, but much smaller than the nickel-metal hydride batteries Bale. However, attention is needed to carry out charging as much as possible to avoid too long, the general control within 12 hours. Laptop battery with the Charger is available with the maintenance of avoidance!


Laptop battery life not by the length of the total duration of use, but by the charge and discharge times to decide. This is the importance of maintenance of laptop battery - Li-ion laptop battery life by charging and discharging to determine the number of times! If you are using a laptop when the battery has been loaded to a notebook instead of taking down, then even if the machine shut down and remove the After the AC power supply, the battery will not as you imagine, as always maintained when fully charged state. Because the laptop battery is used in an integrated control circuit, even when the computer is also shut down power Hp F1739A battery consumption. 1 AC power is connected, this time the battery is not full capacity, so it will soon start charging. In this way, whenever the power turned on or off, your laptop battery will be repeated charge and discharge, shortening the battery life, which is maintained in a laptop battery bogey.


To do this, the use of an external power supply when the AC is best to unplug the battery. Moreover, the laptop battery a long time in a fever state will have an impact on their life. In order to maintain long-term non-use of laptop battery, please charge and discharge at least once a month to ensure that the battery Hp OmniBook 6000 battery activity. At the same time we must pay attention when the battery in the custody of a problem. That is, the vast majority of laptop battery currently used in lithium-ion batteries do not use the words, if a long time, often prone to the phenomenon of excessive discharge, may no longer be able to recharge the battery on the laptop. This is the laptop battery maintenance of a bogey! In order to prevent over-discharge the battery can be charged in the semi-state of the battery stored in the shade, and then every six months, and then to half of its electricity charge state. Laptop battery storage battery maintenance bogey too long, as well as the battery over-discharge damage to the battery!


In addition, the impact of notebook battery life factors including the use of the environment temperature (below 30 ℃ proposed use), battery storage and battery temperature Hp F2019B battery suffered shock size. Laptop battery in use after a period of time will be aging (no matter how maintenance can not be avoided!), Is specifically expressed in resistance of larger, when the charging voltage across rise faster, so easy to charge control circuit judge To have full capacity naturally dropped. The laptop battery correction is an effective way to deal with aging batteries, which is where a number of laptop battery maintenance methods more commonly used as a! However, only a small number of laptop batteries Hp F2019A battery will have a dedicated calibration software. If your laptop not have a dedicated discharge software, then the battery can be maintained in accordance with the following steps:


● Disable the screen saver;

● In the Windows Power Management power scheme will be set to "always open";

● In the Alert tab will be "insufficient power warning" is set to 10%, the operation is set to "no action";

● will be "a serious power shortage alert," set to 3%, operating as a "pending";

● the screen brightness to the maximum;

● confirmed that closed all the windows, and keep all the previous work of the data;

● confirmed that over 80% battery charge after the unplug the power and all external devices.


Discharge after the notebook will automatically shut down after the Hp F2019 battery power plug for laptop charging, this process can be repeated 2 to 3 times to let the battery continuous low current discharge, which discharge status in our daily use is not possible achieved, the effect of the discharge and those dedicated basically the same software.

hp laptop battery maintenance problems

First use the battery, the former three to be recharged for 12 hours


This is totally unnecessary. Because of the notebook computers Hp laptop battery have improved power management circuitry and charging management system, when the battery reached saturation, the control circuit will automatically switch to the circuit state, so even if sufficient length of time and then also to no avail.


In order to prevent memory effect, we should run out before electric charge do?


Each charge before the pairs of battery discharge is not necessary, but also harmful, because it proved the depth of discharge the battery will shorten the life of unnecessary, it is recommended to use about 10% when the battery can be charged when the. Of course, when the battery power is still more than 30% of the time advisable not to charge, because the memory Laptop Battery effect does exist.


AC plug when the battery should win, so as to prevent the repeated charge-discharge do?


I'll give you the advice is: do not. You may take the natural discharge lithium-ion batteries to refute me, and said that if the natural discharge the battery after the power supply if there is access to repeated charge and discharge will reduce battery life. And I give you "instead of" This is the Hp 346970-001 battery answer for several reasons:


1. Now notebooks are designed to power control circuit of this feature: that when the battery reached 90% (such as most HP models), or 95% would charge, but to achieve this through natural discharge capacity of one time for 2 weeks On the following I will not say when the battery is idle for a month or so to fully charge and discharge in order to maintain the battery capacity, this time you should be concerned about is the battery should be exercising their body rather than being idle again after the charge;


2. Even if the battery has "unfortunately" been re-charged, bringing the loss, it's not a long time do not drop the battery power caused much greater.

3. Your data than you or even your laptop batteries are much more valuable a sudden power failure will not only have damage to your laptop Hp Omnibook XE3 battery and can not restore the data is too late to repent of.


Long-term preservation needs of fully charged battery do?


Read the following table is clear: (percentage of saturation at the time the relative percentage of the initial value)


Storage temperature 40% of the charge state of 100% state of charge


0 degree 98% (one year later) 94% (one year later)


25 degrees 96% (one year later) 80% (one year later)


40 degrees 85% (one year later) 65% (one year later)


60 degrees 75% (one year later) 60% (3 months later)


Obviously, if you want long-term preservation batteries, as far as possible on the dry and low temperature environment and allow the battery remaining capacity in 40% of the ideal, of course, best to take the battery out every month to use them once, both to ensure the preservation of the battery Hp F2024A battery well state, but not so high so that the loss of damage to the battery power completely.


How to use the notebook as far as possible to extend the use of time?


1. The screen brightness to reduce. However, power-hungry LCD screen brightness can effectively be extended to reduce the use of time;


2. Open SpeedStep and PowerPlay power-saving features such as. Now the notebook processors and graphics chips have lower operating frequency and voltage to extend the use of time functions, open the appropriate option can greatly extend the battery life time;


3. The use of the spin-down hard drives Hp F2024B battery and CD-ROM software. Such as NERO DriveSpeed, PowerBooster can reduce software such as CD-ROM, hard drive speed, etc. can also be effective in reducing notebook power consumption;


4. Make good use of standby, sleep and other functions. As a long time without a computer, allowing notebook standby or hibernate, saving electricity extended the life of the computer Hp Omnibook XE battery.

Laptop battery maintenance of Mistakes

This is totally unnecessary. Because of the notebook computers have improved power management circuitry and charging management system, when the battery reached saturation, the control circuit will automatically switch to the circuit state, so long as full on-line, and not to say that the longer you charge can be used longer The.


Second, in order to prevent the memory effect, we should run out before electric charge do?


Each charge before the pairs of battery Hp laptop battery discharge is not necessary, but also harmful. Because it has proven: the battery depth of discharge will be unnecessary to shorten battery life, it is recommended to use about 10% when the battery can be charged when the. Of course, when the battery power is still more than 30% of the time advisable not to charge, because the memory effect does exist.


3, insert the AC when the battery should win, so as to prevent the repeated charge-discharge do?


I'll give you suggestion is: No! Of course, you can take the natural discharge lithium-ion batteries to refute me, saying that the natural discharge the battery after the power supply access will appear if there is repeated charge and discharge, and reduce the battery life. And I give you "instead of" This is the answer for several reasons:


1. Now notebooks are designed to power control circuit of this feature: that when the battery reached 90% (such as most HP models), or 95% would charge, but to achieve Compaq PP2100 battery this through natural discharge capacity of one time for 2 weeks month, when the battery idle for about a month to fully charge and discharge in order to maintain the battery capacity, this time you should be concerned about is the battery should be exercising their body rather than being idle again after the recharge.


2. Even if the battery has "unfortunately" been re-charged, bringing the loss, it's not a long time do not drop the battery power caused much greater.


3. Your data than you or even your laptop batteries Hp DP390A battery are much more valuable a sudden power failure will not only have damage to your laptop and can not restore the data is too late to repent of.


4, the battery unused for a long time to do the need full power?


If you want long-term storage battery, as far as possible on the dry and low temperature environment and allow the battery remaining capacity in 40% of the best. Of course, the best to take the battery out every month to use them once, both to ensure the battery a good state of preservation, but also alienating the loss of damage to the battery power completely.
