Lithium-ion batteries are classified into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolyte of a lithium-ion battery is fluid, and therefore, it is more unstable than a lithium polymer battery. If it hits an external force or uses a charger that does not meet the standard, it may cause the battery to explode. Many mobile phones, laptops, etc.
For portable electronic products, the batteries used are all 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 purchasing.
First, there is no clear capacity. A battery that does not have a clearly labeled capacity (such as 1000 mAh or 1000 mAh) is likely to use a poor quality battery or a recycled battery. Many cheap batteries that are flooded in the market are made using recycled batteries. Although the price is cheap, the life is short and the quality is unstable. Inadvertent use may damage the mobile phone.
Second, there is no guarantee of standby time. Standby time is the continuous use time after the battery is loaded into the phone until the next charge. The batteries sold in the general market cannot guarantee the standby time for the customers. This is because the battery quality is unstable, and many inexpensive batteries use a poor quality battery, so the standby time is short.
3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery is in danger of being deformed, leaking, or exploding. Under the vicious price-cutting competition, the companies are looking for a lower-cost protection circuit board, or simply omitting the device, making the market full of explosive lithium batteries. Consumers can't tell if they have a protective circuit board from the outside, so it's best to choose a reputable merchant to buy.
