Lithium iron phosphate batteries are divided into liquid lithium batteries and polymer lithium batteries. Lithium battery electrolyte is fluid, so it is more unstable than lithium polymer lithium battery, and it will cause the battery to explode when it encounters external force collision, or the charging head that is not used properly.

The rechargeable batteries used in portable electronic devices are all lithium batteries. For better safety, be sure to pay attention to the following aspects when purchasing.

1. Is there a clearly marked capacity? It is very likely that a rechargeable battery that does not have a marked capacity (such as 1000mAh or 1000mAh) is likely to be a counterfeit battery or a recycled battery. At present, many cheap batteries on the market are made of recycled battery cells. Although the price is cost-effective, the cycle is short and the quality is unstable. Careless application may damage the mobile phone.

2. Is it possible to ensure battery life? The battery life is the continuous use time of the next battery charge after the rechargeable battery is installed in the mobile phone. The rechargeable batteries in the general market cannot guarantee the battery life to customers. It is because of the unstable quality of the rechargeable batteries. Many cheap rechargeable batteries use poor quality battery cells, so the battery life is short.

3. Is the safety protection circuit board installed? If there is no lithium battery protection board, the lithium battery will have the risk of deformation, liquid leakage, and explosion. Because of the vicious price-cutting market competition, many manufacturers will look for cheap protection circuit boards, or simply ignore this equipment, resulting in the sales market filled with lithium batteries with the risk of filling up. Customers cannot identify whether there is a lithium battery protection board from the appearance, so choose a reputable store to buy.
