What should I pay attention to when purchasing lithium-ion batteries?

Pay attention to the following points when purchasing: 1. Is there a clear capacity mark? Batteries without a clearly marked capacity (such as 1000mAh or 1000 mAh) are likely to be inferior batteries or recycled batteries. Many cheap batteries on the market are made from recycled batteries. Although they are cheap, they have short lifespan and unstable quality. Careless use may damage the phone. 2. Is there any guarantee of standby time? The standby time is the continuous use time after the battery is installed in the phone to the next charge. Generally, the batteries sold in the market cannot guarantee the standby time for customers. This is because the battery quality is unstable. Many cheap batteries use poor quality batteries, so the standby time is very short. 3. Whether to install a safety protection circuit board. Without the protection circuit board, there is a danger of deformation, leakage, and explosion of the lithium-ion battery. Under the vicious price cut competition, various companies seek lower-priced protective circuit boards, or omit this device at all, making the market full of lithium-ion batteries that are dangerous for explosions. Consumers cannot tell from the appearance whether there is a protective circuit board, so it is best to choose a reputable merchant to buy.
