Lithium ion batteries are divided into liquid lithium ion batteries and polymer lithium ion batteries. The electrolyte of lithium-ion battery is flowing, so it is more unstable than lithium polymer battery. When it is hit by external force, or using a charger that does not meet the standard, it may cause battery explosion. Many mobile phones, laptops and other portable electronic products use lithium batteries. In other words, many people have a "bomb" around them. For the sake of safety, you must pay attention to the following points when shopping.
1、 Whether the capacity is clearly marked. Batteries without clearly marked capacity (such as 1000mah or 1000 MA / h) are likely to use inferior batteries or recycled batteries. Many cheap batteries in the market are made of recycled battery cores. Although the price is cheap, the service life is short and the quality is unstable. Careless use may damage the mobile phone.2、 Is the standby time guaranteed. Standby time refers to the continuous use time from the time the battery is loaded into the mobile phone to the next charging. Generally, the batteries sold in the market cannot guarantee the standby time for customers, because the battery quality is unstable. Many cheap batteries use poor quality battery cores, so the standby time is very short.
3、 Whether to install safety protection circuit board. If there is no protective circuit board, the lithium battery will be in danger of deformation, liquid leakage and explosion. Under the vicious price cutting competition, all companies seek lower price protection circuit boards, or omit this device at all, making the market full of lithium batteries with explosion risk. Consumers cannot tell whether there is a protective circuit board from its appearance, so it is best to choose a reputable business to buy it.
