Lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolytes of lithium-ion batteries are mobile, so they are more unstable than lithium-polymer batteries. When they are hit by external forces, or when they use non-conforming chargers, they may cause battery explosion. Many mobile phones, laptops, etc.
Portable electronic products, the batteries used are lithium batteries. That is to say, many people have a "bomb" beside them. In order to be safe, you must pay attention to the following points when choosing to buy.
1. Are there clear capacity labels? Batteries with no clearly marked capacity (such as 1000 mAh or 1000 mA hours) are likely to use inferior batteries or recycle batteries. Many inexpensive batteries in the market are made from recycled batteries. Although they are cheap, they have short life and unstable quality. Careless use of batteries may damage mobile phones.
2. Is there a guarantee of standby time? Standby time is the continuous use time from the battery to the next charge. Generally, batteries sold on the market can not guarantee standby time for customers, because of the unstable quality of batteries. Many cheap batteries use poor quality batteries, so standby time is very short.
3. Whether to install safety protection circuit board. Without a protective circuit board, lithium batteries are in danger of deformation, leakage and explosion. In the vicious price competition, each company seeks to lower the price of the protective circuit board, or simply omitted the device, making the market full of explosive lithium batteries. Consumers can't tell from the appearance whether there is a protective circuit board, so it's better to choose a reputable business to buy.
