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 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.

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.
