Lithium battery purchasing method

Lithium batteries are divided into lithium-ion batteries and lithium polymer batteries. Lithium-ion battery electrolytes are fluid. Therefore, they are more unstable than lithium-polymer batteries. When they hit an external force or use a non-standard charger, they may cause the battery to explode. Many mobile phones, laptops and other portable electronic products use lithium batteries. In other words, many people have a "bomb" around them. For your safety, you must pay attention to the following points when purchasing.

I. Is there a clear indication of capacity? A battery that does not have a clearly marked capacity, such as 1000 mAh or 1000 mAh, is likely to use a poor battery or a recycled battery. Many of the cheap batteries in the market are made from recycled batteries. Although the price is cheap, they have short life span and unstable quality. Inadvertent use may damage the mobile phone.

Second, there is no guarantee of standby time. The standby time is the continuous use time after the battery is loaded into the mobile phone until the next charge. The battery on the general market cannot guarantee the standby time for the customer. This is due to the unstable quality of the battery. Many inexpensive batteries use a battery with poor quality, so the standby time is very short.

Third, whether to install security protection circuit board. Without a protection circuit board, there is a danger of lithium batteries deforming, leaking, and exploding. In the competitive competition, each seeks for a lower-priced protective circuit board, or simply omits the device, making the market filled with lithium batteries that are dangerous to explode. Consumers cannot distinguish from the appearance of whether there is a protective circuit board, so it is best to choose reputable businesses to buy.
