How to choose lithium battery

How to choose lithium battery
1. Look at the appearance
Looking at the appearance refers to the appearance, workmanship, size and craftsmanship of the lithium battery. Check whether the seam line of the shell is wide, whether there are burrs, oil stains, and whether it feels good to the touch. The advanced technology is very comfortable to the touch. After grinding, the rubber oil polishing material not only feels good, but also has strong insulation performance. .
2. Check whether the capacity is clearly marked
A lithium battery without a clearly marked capacity is likely to be a garbage battery reassembled using inferior battery cells or recycled battery cells. There are many cheap lithium batteries on the market, which are made of recycled battery cells or disassembled battery cells. Although the price is cheap, the life is short and the quality is unstable. Careless use may damage the device or even explode.
3. Look at the protection circuit
The characteristics of lithium batteries determine that lithium batteries must be equipped with protective plates to prevent overcharge, overdischarge and short circuit of lithium batteries. Lithium batteries without protective plates will have the danger of deformation, leakage and explosion. Under fierce price competition, various battery packaging factories seek lower-priced protection circuits, or omit this device at all, making the market flooded with explosive lithium batteries. Of course, in fact, consumers cannot tell whether there is a protective circuit board from the appearance, so it is best to choose a trusted business to buy.
4. Look at the brand
There are many brands of lithium batteries, but the quality is difficult to see from the appearance. In this case, everyone should do more homework before making a choice, and check the manufacturer's information online. Generally speaking, professional manufacturers are more reliable than small workshops, and manufacturers who have been in the industry for a long time are more trustworthy than those who have just entered the field.
