How to select lithium battery

Lithium batteries are divided into liquid lithium batteries and polymer lithium batteries. The electrolyte of lithium battery is fluid. Therefore, it is more unstable than lithium polymer lithium battery. If it encounters external force collision or fails to pass the application of charging head, it will cause battery explosion.

Rechargeable batteries for portable electronic devices and applications are lithium batteries. For better safety, you must pay attention to the following aspects when purchasing.

First, is there a clear capacity for signs. It is very likely that rechargeable batteries without established marked capacity (such as 1000mah or 1000 Ma Pei hour) are likely to be the application of fake batteries or recycled batteries. At present, many cheap batteries in the market are all made of recycled battery cells. Although the price is cost-effective, the cycle is short and the quality is unstable. Careless application is likely to destroy the mobile phone.

Second, is it possible to ensure the endurance? Battery life refers to the continuous use time of the next battery charge after the rechargeable battery is installed in the mobile phone. Generally, rechargeable batteries in the sales market can not guarantee the endurance to customers because of the unstable quality of rechargeable batteries. Many cheap rechargeable batteries have a short endurance because they use poor quality battery cells.

Third, is the safety protection circuit board installed? If there is no lithium battery protection plate, the lithium battery will have the risk of deformation, liquid leakage and explosion. Because of the vicious price reduction market competition, many manufacturers will look for low-cost protection circuit boards, or directly ignore this machine and equipment, resulting in the full risk of lithium batteries in the sales market. The customer could not identify whether there was a lithium battery protection board from the appearance, so he chose a reputable store to buy it.
