Teach you how to buy lithium battery

The lithium battery is divided into lithium-ion batteries and lithium polymer battery. Lithium-ion battery electrolyte flowing solid polymer lithium battery electrolyte, lithium-ion battery is more volatile than the lithium polymer battery, hit the external blows, or does not meet the standard charger, may cause the battery to explode. The batteries are lithium batteries use a lot of mobile phones, laptops, digital cameras and other portable electronic products. Buy poor quality lithium battery, just like in his side put a "time bomb". Therefore, consumers in the purchase of lithium battery must pay attention to the following points:

Capacity is clearly marked. No clearly marked capacity (2200mAh or 4400mAh) lithium battery, is very likely to use poor quality battery core or recycling battery core reassembled garbage battery. The market flooded with cheap lithium battery is done using recycled battery cells or disassemble battery core, although the price is cheap, but life is short, unstable quality, careless use may damage the phone, or even explode.
Whether the guarantee of standby time. The standby time, i.e. the time of the lithium battery into the phone to the next charge of continuous use. General market sales of lithium batteries are not customer guarantee standby time, this is because the battery, unstable quality, many cheap battery because the use of poor quality battery core, so standby time is very short.
Whether with safety protection circuit. The characteristics of lithium batteries lithium batteries must be plus protective plate to prevent the lithium battery overcharge, over discharge and short circuit from happening, without lithium battery protection board will have deformation, leakage and the risk of explosion. Fierce price competition, the battery packaging factory seeking lower-priced protection circuit, or simply omit the device, so that the market is flooded with lithium battery explosion hazard. Consumers can not tell the difference from the appearance of whether there is a protection circuit board, so it's best to choose a reputable merchant to buy.
