A laptop battery factory executives

A laptop battery factory executives said the government testing and quality inspection departments are generally in accordance with product labeling dell Latitude C600 battery capacity to detect, and the results are certainly not

Qualified. laptop battery is not really poor and can not be used, the question is false capacity.

However, the consequences of false endemic soon be reflected in the market. "At the time of such false phone dealer will say that the ultra-long standby battery capacity, to attract consumers." The executives said that many imitators are at a loss, and a large number dell Latitude CPX battery of stocks have a low price-dumping market.

Shenzhen Mobile Industry Association executive vice president of Sun Wenping that it in fact a true ultra-long standby laptop and the battery will not make too many articles, more technical levels in the power of the phone itself.

Crackdown launched quietly

In fact, false laptop battery capacity problems throughout the business sector has already attracted the attention and the quality inspection departments, and have taken enforcement actions.

Apart from Beijing Technology and Business Council, in January of this year, Sichuan, Jiangxi, Shanghai, Shenyang and relevant departments of the four pairs of laptop batteries dell Inspiron 2500 battery on the market for quality aspects of sampling, and sample test results notification. The results showed that the four laptop batteries to sell nothing but the highest pass rate of 75%, of which the battery capacity of making a false statement is a major quality problems.

Wu Jianmin said that the Joint Development and Reform Commission by the Ministry of Information Industry and other seven ministries issued "Management Measures" after thorough investigation of laptop battery capacity was found during the rather serious problems in making a false statement, which will also focus on law-enforcement inspection in accordance with the law enforcement during the caliber of electronic information products meet the "management approach" to conduct spot checks to integrating them into their daily dell Inspiron 4100 battery work.

According to a number of laptop battery factory in Shenzhen revealed that around January of this year, Shenzhen food safety regulator has sent people to inspect factories, focus on examination of the contents of the cell phone battery is a product identification is true.

A high level of domestic laptops, said false battery capacity the battery manufacturer's modus operandi, non-laptop manufacturers original capacity of the battery dell Inspiron 4000 battery is almost always false. However, this practice is seldom used brand laptops, after all, go through MII testing.

This reporter has learned, as many do ultra-long standby laptop manufacturers in the years before the stock sell-off to the phone channel, currently on the market there are still a considerable number of such false laptop battery for sale

laptop battery capacity of thorough investigation of false start quietly

laptop battery capacity of thorough investigation of false start quietly

2000 milliamperes, 3000 mA, 4000 milliamperes, 5000 mA, the battery Laptop Battery capacity of laptops on the market rising. However, according to "First Financial Daily" reporter has learned that the rising cell phone battery capacity, of which a considerable part, to meet consumer demand for ultra-long standby and false reports.

Recently, the Beijing Municipal Bureau of Commerce and Industry commissioned the Beijing Information Product Quality Supervision and Inspection Station of the Beijing cell phone batteries sold for quality testing, notification of 16 brands of quality laptop battery failure, of which 15 brands of quality laptop batteries because of false report of the battery capacity. Beijing Municipal Industry and Commerce Bureau ordered the 16 kinds of brand laptop battery out of the Beijing market, and will sell the operators of substandard goods according to law.

"First Financial Daily" from the number of laptop battery dell 5081P battery factory in Shenzhen, that since the concept of ultra-long standby laptop market is very popular, resulting in the entire laptop market in the battery capacity on the false rife, not just brand-name laptops, and even individual well-known brands are the existence of this phenomenon. However, this false report has also led to a crisis of confidence, stock dumping large enterprises is the evidence.

Research Institute of China Electronic Information Industry Development Director Wu Jianmin said in October last year to 12 months, according to Ministry of Information Industry, the Customs Department, the State Administration for Commerce and Industry, State Administration of Quality Supervision, Inspection and Quarantine jointly issued a four-sector office "About "Electronic Information Products Pollution Control Regulations" (hereinafter referred to as "Regulations"), issues related to notification of law enforcement ", by the local electronics and information industrial joint customs, industry and commerce, quality inspection and other departments, including electronic products, including laptop batteries to carry out focused examination, found that laptop battery dell 75UYF battery capacity problem is very serious hoax.

False become a common practice

"If the laptop battery capacity of 4000 milliamperes have been very dangerous, manufacturers have to bear the risks are very high." Energy company, general manager of Shenzhen City Nosil He said that when the river, 4,000 mAh battery, if short-circuit lead to disastrous consequences. laptop manufacturers and battery manufacturers are well aware of this risk is generally not going to take this risk.

According to reports, no matter the brand or the brand-name laptop, the phone quality requirements are very high, the provision of laptop accessories supplier requirements are very strict, are usually entered into the so-called security protocols, once the cell phone because the battery dell 1691P battery causing fire and explosion problems Each incident cases of laptop batteries suppliers, the amount of compensation may be 50000, 10 ten thousand dollars.

From a technical point of view, in the current level of technology, the general laptop battery capacity peak so far of 1000 milliamperes, through the thickening can be achieved from 1700 to 1800 milliamperes. If the battery capacity of more than 3000 milliamperes, the average cell phone battery factories have been unable to produce, not to mention the production of 4000 milliamperes batteries.

However, copies of last year, Ersan Yue began the use of brand-name laptops and large screen, ultra-long standby concepts such as best-selling in the market, the overall laptop dell Latitude C640 battery market began to follow the trend from last year were newly settled. "Actual capacity is only 1200 milliamperes, laptop manufacturers require S to 2000 milliamperes; product label is the 4300 milliamperes, the actual capacity may be only 2000 milliamperes." He, when Jiang said most of the capacity of high-capacity batteries are false.

Reporter on the Internet through the GOOGLE search, in line with "4000 milliamperes laptop batteries" dell Latitude C610 batteryof the query results as much as high as 123,000. Individual brand-name laptop laptop battery capacity will also be false to 6800 milliamperes, or even 8000 milliamperes.

At risk of overheating it would recall 46 million dell batteries

At risk of overheating it would recall 46 million dell batteries

As the battery charger may short-circuit temperature is too high risk exists. Recently, dell dell 312-0306 battery announced the global recall of 46 million BL-5C mobile phone batteries.

dell said the battery replacement is limited by the Matsushita Company in December 2005 to November 2006 during the production of BL-5C batteries have been used from the 1100 series of low-end to high-end N91 and E60 products multiple models . For reports of overheating, dell said that the world is about 100 onwards, and has not received any serious personal injury or property damage dell F5136 battery were reported.

Marianne Holmlund, said company spokesman, overheating will cause the battery charger from the phone, "pop." She said that, although they do not know what causes a small number of incidents, but the battery does not exist the danger of fire. dell said the company in 2006 sold 347 million mobile phones, cell phone batteries use only one of about 10%.

It is understood that the problem the Chinese market dell Inspiron 710m battery will also be a unified replacement batteries. As for the Chinese market will be the number of defective batteries, dell Customer and Market Operations IT Manager, LIU Yan said there was no relevant statistics.

She introduced, customers will only have the battery on the back below the 26-character battery identification number, through the dell website or customer service hotline to identify, you can determine whether the free replacement battery conditions. dell will use DHL courier, sent a new battery. For areas not covered by DHL, dell will take the form of other courier dell Inspiron 700m battery delivery.

dell , Panasonic will recall program is expected to bear "certain financial responsibilities", the two sides will investigate the battery issue. If all 46 million customers decided to replace the battery, then the cost of the recall would be very high. However, the Matsushita spokesman said the general in such cases, only a small part of the customer will be returned to the battery.

Promotion master Gonglue: How ThinkPad Battery

Into the relevant Enterprise Center is well known, Thinkpad notebook Laptop Battery has often been dubbed astronomical reason for sale, not only because of its excellent product quality, in addition, but also with the product and its many applications, while providing a great relationship. In this being, Thinpad notebook equipped with a battery management chip inside the battery, and then with power management software, so Thinkpad laptop's battery during use there is plenty of room for user attention.

First, note that the details of the use of

In the actual use of the process, many of the details have not been noted, has affected the life of your battery dell Latitude D510 battery. For example when the AC-powered laptop at the state shutdown, waiting for the power indicator light and the bottom of the screen all the lights off after the exchange with the plug pulled (not later than 5 seconds). After the lights go out because the power supply board are still working, this time will begin to pull the plug on the battery, thereby accelerating the battery more quickly fell to the charging power to set the starting value, thereby reducing the battery charge with the cycle, affecting the battery's life.

In addition, when using AC power supply, the adapter plug the input plug and output plug (unload) the correct sequence of operations is: First the AC adapter's output plug into the power jack plug, and then plug into the input plug power dell Latitude D505 battery outlet; and should be removed when the input should first unplug the plug, then pull the plug then the output. This will prevent the adapter has been damaged in a no-load state.

2, in-use maintenance and storage of

1, the battery charge times by their limited life span, so there are places in which AC power, they should make full use of AC power to minimize the number of battery charging to extend battery life;

2, when the electricity is 3% to 5%, it is timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine can be in any state, side by side rechargeable battery also will not hurt ;

3, power is not fully depleted before (ie electricity at 5 ~ 100%), not to recharge the battery, otherwise they will reduce the charge to increase with cycle number of charge cycles and shorten dell Latitude D500 battery the battery life;

4, if the battery a long time (several months) do not, remove the saved backup from the machine; if the battery a long time unused, it should be set to 30% of electricity consumption to 50% in storage; Do not put the battery temperature and cold environment, the battery performance will be temporarily reduced. Should be at standby mode to save battery life and storage of the state placed in places of lower temperature for the battery, the best temperature range is about 10 ~ 20 degrees Celsius.

Third, on the activation of the battery deal

As we all know, just purchased a new Thinkpad batteries dell Inspiron 600m battery to activate processing, ie 100% charge and discharge, in fact, a random Thinkpad help to say "re-engineering of your battery every month, that your battery is 3% or less, this will Increase your battery capacity, "is intended to adjust the battery management chip and charge control chips in the normal value of each register. Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery power, and if the chip has not been opportunity to once again read out the full curve, calculated results can be inaccurate, and therefore need the deep charge put to adjust.

Concrete method is to click the "Battery Maintenance" - "" implementation of the re-setting. "

4, on the charge adjustment of the starting threshold

If you mainly use AC power, only occasionally use the battery, you can change the battery charge threshold, to increase your battery life. Pre-charge start value of 96%, because the battery dell Inspiron 510m battery is fully charged after the phenomenon of self-discharge of electricity due to fall to 96% generally lasted about 50 days, while the battery every month and a half or so just in need of a discharge and charge order. But if you often need to live in the office and equipment, between the "Two Cities" campaign to curb the power supply and battery-powered AC adapter to switch between the frequency should be charging start value is set to 6%, which can be avoided with the cycle due to reduced charge increase the number of charge cycles and shorten battery dell Inspiron 500m battery life. Concrete method is to click the "Battery Maintenance" - "change" began to charge less than the following value, "values.

Note:

1, charging threshold is set to run only in the case of Battery MaxiMiser effective;

2, charge termination charge than the initial percentage of the high percentage of at least 4%;

3, due to cell aging, generally charging threshold is set higher than the ideal value of 2%;

4, when the charging stops when the percentage is less than 100%, please battery dell 312-0305 battery every three months to conduct a 100% charge.

Enlightened and teach you buy cell phone batteries five big trick

Enlightened and teach you buy cell phone batteries five big trick

How to choose mobile phone battery is still subject to the concerns of consumers. But nowadays a lot about the cell phone battery Laptop Battery purchase the article are often starting from the observation areas, superficial, we might look at a deeper level, this issue, passing on to consumers in a number of "trick", easy to get really suitable for mobile phone battery.

Battery capacity is also false standard, and passed the brand is the key first is the capacity of the battery. The capacity of the battery level is determined by the core battery accessories - batteries to decide, but because the batteries are wrapped in the battery inside, as if the market for sale Red duck egg - can not be seen from the surface, good or bad, but the cut open to observe, then the battery itself would be destroyed, but can not be used - under the guise of the shell, the capacity dell Inspiron 630m battery of virtual standard has become the first problem faced by consumers. The so-called virtual-standard, that is, the actual capacity of the battery capacity is lower than the outer mark. The mobile phone battery market is now widespread this problem, the general scope of virtual object in 200-300 milliamperes, and some even reached 500 mAh - which means that consumers no reason to lose 1 / 5 or even 1 / 3 of standby time. This involves the integrity of the enterprise business problems, consumers alone that he is unable to accurately determine. To avoid this problem the best way is to choose a really good brand of battery, such as the Scud batteries, its products and the virtual standard battery on the contrary, the actual capacity of the battery Scud packaging marked capacity higher than 30 mA time.

Security news of mobile phone battery dell 6T473 battery exploded repeatedly hit the newspapers, however, consumers should avoid this one to an unknown theory, and secondly, a lack of professional detection means, the only solution is to choose the brand batteries. Scud on the battery to take "safety valve" to protect board plus a "double protection." Against short circuits caused by high-pressure high-temperature conditions, Scud batteries a "safety valve" for protection, its principle is similar to the daily household use pressure cooker valve that can occur in the battery when the drums through the gas valve will be let go -- - This is the first tier of Scud battery safety protection; and in the battery core security components - the protection board, the adoption of overseas imported Scud-MOSFET, protect the IC and other components, occurred when the battery charge, over-current, resulting in high temperature and pressure When the protection plate chips in its reaches a certain critical point, before automatically cutting off dell Inspiron 5100 battery power supply, thereby preventing the battery continues to heat up step-up causing a fire, explosion - this is the Scud batteries second layer of protection. Such products, safety, of course, is very high.

Pollution control our every day and mobile phones, "Erbinsimo," but mobile phone battery itself is a huge source of pollution, which states "Electronic Information Products Pollution Control Regulations" set clear lead, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) as the mobile phone battery that contains the six most serious pollution of heavy metals. China's pollution control measures taken on the grading system, according to an annual division, a total of 11 levels. For example, one that environmentally friendly products can be used in a period of one year, two for 2 years, and so on ... ... no pollution products are referred to as "e"-class. For the mobile phone battery dell Inspiron 1100 battery products, environmental protection, service life requirement of 3 years. The Scud batteries environmentally reached five years of life, through the authority of the testing, the implementation of SJ/T-11364 Electronic Information Products Pollution Control Standards and implementation of standard quote management, and is currently on the market green life of the longest mobile phone batteries.

How do anti-counterfeit labels anti-counterfeiting issues should also be brought the attention of consumers. In fact, mobile phone batteries on the market from packaging in terms of basic similarity, many fail to see what the battery manufacturers to produce products. Low-quality products are often from fish in troubled waters. Take Scud, the large number of counterfeit products flooding the dell C1295 battery market. To this end, Scud specializing in packaging upgraded security measures by adding laser anti-counterfeit labels, while each cell has a one to one security code, scratch covering the security code on the film can see, consumers can be telephone or text message to the manufacturers check the check to verify whether their purchase of the battery is not genuine Scud mobile phone batteries. In such anti-counterfeiting measures, under the protection of the rights of consumers in order to be fully protected.

After-sales service Finally, the price of a battery-Although there is no cell phone, DV and other products as high, but the problem still exists after-sales service. Scud batteries has always been committed to "7 days caveat vendor, 30 days replacement, a 180-day failure replacement, life-long maintenance of" after-sales service policy for consumers to solve the last one to worry about, the full assurance of the interests of consumers.

Conclusion In summary, cell phone battery dell 1X793 battery purchase, not only to see prices superficial problems. As for the identification of good and bad cells, but also no longer touching the touch, and take a look at the battery and cell phone, the color of the nose is the same so simple and obvious method can be resolved. In fact, the cell phone batteries buy the ultimate solution, but also in the trust and the purchase of "Scud" This brand of batteries, can truly deserve protection.

Let your second-hand laptop battery recycling

Let your second-hand laptop battery recycling

For batteries, a lot of people thought it was a simple thing, but by the time a problem is not unaware of even the kind of hands-on is unable to find the appropriate accessories, when looking for a battery Laptop Battery that is very difficult to exactly the same, or the price unacceptable, then the only allows integration of a laptop as a desktop machine, and it is a pity, and there are ways around this? The answer is yes, in fact, all laptop batteries for all media is just two kinds, one is a hydrogen battery, a battery is the reason, as long as you have some hands-on capability (the main thing is confidence) then the world is that there is a rare live your thing! ! !

First, make sure your books are the kind of media, and generally have the battery dell PC764 battery shell is marked, and people do not know the English does not matter if the battery shell is nothing but a few hundred words, if there are NI-MH tags (the word), then congratulations to you , because you are away from success recently,, NI-MH battery marked state your medium is hydrogen battery, you must first engage in several batteries back from the electronic market to buy or purchase from a very hit network. The battery is used to trumpet shape Jiugen at home almost the same as the battery is no packaging, voltage unity is 1.2V (if you even do not know 1.2V is the voltage value, then the following article you do not read) and the capacity is not the same, as household batteries, like trumpet, medium voltage is 1.5V, but the use of the same as the dell 312-0386 battery output current, then the numbers must be used for longer than the trumpet. Conditions as the price to purchase high capacity although there is some discrepancy.

With the battery, then the next step is to give your battery an operation, because the battery is a "patient" as "a doctor you should be careful, (and do not have an accident) and that an operation of the tool is necessary. Screwdriver , pliers, saw blade, lighter, small copper wire, an adjustable DC voltage 1v to 12v transformer (small appliance stores sold), household fuses, electric iron, insulating tape and so on. these things are available from hardware store buy. Most of the battery dell Latitude D620 battery shell casing from the upper and lower bonding formed from the middle, then we are also bonded areas from its sawing it, (this process is the most troublesome to build off the success of) gradually saw in order to be sawn in a straight line after the bonding process, but also your patience and ability to test. saw the time be careful not to saw the parts inside the battery bad, anyway, the mentality of a doctor, it wants to deal with the battery.

Sawing the post you will find inside is just N a (sometimes N is greater than 10) battery series-parallel and Fall, (well sort of!) Yes, in fact, several battery strings in parallel, series is up to standard work voltage, in parallel for up to a certain battery capacity (ie, notebook usage time), in fact there are problems in most cases is not each section of the cell but only one of one or more sections, from which it points out the need of wisdom the maintenance process is put the batteries dell RC107 battery a few problems were found with the purchase to replace the normal cell generation, the problem is so simple.

Well, the battery begins to undergo an operation, and the battery removed a 1 (that is, the connection between the battery sawing, it is best to make a sketch on paper so as to avoid loss of memory), the battery can be divided into positive and negative electrodes , and with the battery connected and the smooth side of the shell is negative, the other side is the cathode, the battery's function is to save electricity, and discharge. Then verify that a battery is good or bad is to test its storage, discharge capacity, we set an initial battery charge, the surgical instruments mentioned in the transformer transferred to 6v, then the positive battery dell Y9943 battery cathode, anode then the battery negative (this is a super-pressure charging ), each cell 5 minutes stopped five minutes due to two, one is for transformer cooling, 2 is the battery "rest." About eight times this operation to complete the process of rechargeable batteries, compared to test for the discharge process is much more simple and fun, take a home side take the negative side of the fuse then the positive (short-circuit discharge) If the fuse immediately fuse, then this section is a good , and the other hand, if no response is the problem then this section of the battery cell of (Oh ... victory in front of). All this has put the batteries in question instead of using the normal battery, connected the battery and then carefully put it back into the shell, the bond and then back into the good books to try, you will be dell Inspiron 640m battery very happy. This news to a friend might be able to return for a few words to commend or a few Kiss it ... ...

Shanghai mobile phone battery checks into a substandard performance to be improved 3

Shanghai mobile phone battery checks into a substandard performance to be improved 3

Recently this reporter learned from the Shanghai Quality and Technical Supervision, in its most recent spot check Laptop Battery in the supervision of mobile phone batteries on the market production and sale of non-original battery status of poor overall quality, this Shanghai Quality and Technical Supervision Department had taken 15 kinds of mobile phone battery products, of which 10 qualified and unqualified 5, sampling pass rate was only 66.7%, mobile phone battery safety performance needs to be improved.

In the past in 2007, involving the safety of mobile phone batteries dell Inspiron 8500 battery continue to emerge. In Gansu in June last year, there have been bombing the country's first fatal case of piles phone to Nokia announced a worldwide recall 46 million of the original existence of hidden batteries, and then to burst out all over the cell phone battery exploded wounding incident. This series of events have shown is that to the mobile phone battery safety under the Vice "strong medicine" of.

Mobile phone battery safety can not be ignored

People's daily lives mobile phone is an indispensable communication tool among the nearly 24-hour companionship around, has become a very important part of people's daily lives. At present, China has more than 540 million mobile phone users, is the world's mobile phone users than any other country. For this reason, mobile phone security has been a lot of people's attention, particularly the safety of dell Latitude D800 battery mobile phone battery.

Mobile phone battery is a certain danger of chemical industry products, so safety is very important. If you are experiencing over-voltage, over-charging mobile phone batteries, etc. will be fever, does not meet the safety standards, the product is very likely to catch fire, explosion, caused by personnel and property losses. In recent years, mobile phone batteries due to fire caused by the blast in the global incidence.

Mobile phone battery dell 312-0393 battery explosion took place, who are hurt not only mobile phone users, manufacturers, distributors also are victims. Therefore, mobile phone battery safety can not be ignored, need to attract vendors, channel providers, government departments, consumers, the media of common concern.

Manufacturers blame

Mobile phone battery hidden safety problems are caused by several factors, one important reason is that technically immature. Currently on the market used in lithium-ion battery technology is still defective and therefore can not completely avoid the possibility of an explosion. Tokyo University of Technology Professor MasatakaWakihara pointed out that "in the safety design of lithium batteries dell YD626 battery, battery manufacturers is still in the learning phase, as manufacturing technology is not yet mature, therefore, the current lithium-ion battery there is a fundamental flaw in the design, it is necessary to avoid security problems, it is necessary to completely change the manufacturing methods. "

Second, the mobile phone battery manufacturers have to bear a great responsibility. A lot of regular cell phone batteries, battery manufacturers strict quality control, in July last year, Industry and Commerce Administration, Guangdong Province, found in the sample, four batches of cells with the trial, the samples burst into flames, involving Motorola, Nokia and other brand-name products. At the same time, the formal marketing channels and brand manufacturers are doing enough publicity. Many original equipment batteries are placed in stores to sell products, and expensive, resulting in many consumers to look, "price" sigh. This is tantamount to those who counterfeit mobile phone batteries dell MM165 battery are also a potential market.

Again, uneven quality, the proliferation of fake and shoddy products are mobile phone battery safety issues emerging one of the factors. A lot of lawless elements coveted mobile phone battery market is a piece of "cake", in order to reap big profits produced inferior battery. Inferior battery in order to save costs, cutting corners is very serious, so that the battery lacks the necessary technical protection measures, prone to fire, explosions and other accidents such comparisons vicious, threatening consumer safety.

Finally, the safety of consumer awareness of mobile phone battery dell Latitude D830 battery weak, those who yield to the temptation to buy cheap counterfeit mobile phone batteries, plus usually improper use of mobile phone batteries, mobile phone battery has also led to security risks from arising.

Urgent need to improve the access threshold

Mobile phone battery to solve the security issues should be multi-pronged approach. First, from the monitoring and improving the products, the market threshold. For those who frequent quality problems, quality, low passing rate of the battery brands to be off the market. Black mobile phones, as well as to increase efforts to crack down counterfeit mobile phone batteries.

Second, firms from the technology research and development start with the greatest degree of assurance of the safety of mobile phone batteries. For now, cell phone batteries use lithium-ion batteries are still the main ways to avoid defects in lithium battery technology to improve safety will be the R & D focus. In addition, the fuel cell is very likely to replace the current lithium dell Latitude D820 battery batteries, while the solar cell is the future of mobile phone battery development.

Third, the proliferation of mobile phone battery problem is the crisis facing the mobile phone battery manufacturers, in fact, is also a brand and win market opportunities. Mobile phone battery manufacturers should consider creating a good channel for consumers to purchase through the authority of the channels, cell phone batteries. To enhance brand awareness in the public's trend, if the mobile phone battery brand stores across the country can be so fake batteries will gradually lose their living space. Of course, the relevant departments should intensify efforts to combat counterfeit mobile phone batteries, cell phone batteries to avoid the inferior spread in the market and damage the public interest.

Finally, the country needs as soon as possible cell phone battery dell TD175 battery standards. From the development of the industry trend, mobile phone battery need a new standard. At present the safety performance of mobile phone battery, and there is no specific certification standards, which makes a variety of vendors their own ways, so that will no doubt leave some security implications. Therefore, as soon as possible mobile phone battery standards are conducive to promoting safety certification, raising the technological level, standard mobile phone battery market.
