Lithium Battery Selection Method

Lithium ion batteries are divided into liquid lithium ion batteries and polymer lithium ion batteries. The electrolyte of a lithium ion battery is fluid, so it is more unstable than a lithium polymer battery. Falling against external forces or using a charger that does not meet standards can cause the battery to explode. Many portable electronic products such as mobile phones and laptops use lithium batteries. In other words, many people have a "bomb" around them. For safety reasons, you must pay attention to the following points when purchasing.
1、 Is the capacity clearly marked. Batteries that do not have a clearly labeled capacity (such as 1000 mAh or 1000 milliampere hours) are likely to use inferior or recycled batteries. Many cheap batteries on the market are made from recycled battery cores. Although they are cheap, they have a short lifespan and unstable quality, and careless use can damage your phone.
2、 Is standby time guaranteed. Standby time refers to the continuous usage time from the time the battery is loaded into the phone to the next charge. Generally speaking, batteries sold on the market cannot guarantee standby time for customers, which is due to unstable battery quality. Many cheap batteries use poor quality battery cores, so standby time is very short.
3、 Whether safety protection circuit boards are installed. Without a protective circuit board, there is a risk of deformation, leakage, and explosion of the lithium battery. In the face of vicious price cutting competition, companies are seeking lower price protection circuit boards or simply omitting this device, making the market full of lithium batteries with explosive risks. Consumers cannot tell from the appearance whether there is a protective circuit board, so it is best to choose a reputable merchant to purchase.
