Look at the surface
Look at the appearance is to look at the appearance, technology, size and technology of the lithium battery. See if the width of the shell suture is wide, whether there is burr, whether there is oil stain, feel good, advanced technology is comfortable, after polishing, the rubber varnish material feels good, and the insulation function is also strong.
2. See if the capacity is clearly marked
Lithium batteries without a clearly marked capacity are likely to be junk batteries assembled from scratch with defective or recovered batteries. The mall is flooded with many cheap lithium batteries, which are made by recycling batteries or disassembling them. Although they are cheap, they have a short life span and unstable quality. If accidentally used, they may damage the equipment and even cause an explosion.
3. Look at the protection circuit
The characteristics of the lithium battery determine that the lithium battery must be added to the protective plate to prevent the lithium battery from overcharging, overdischarging and short-circuiting. For example, the lithium battery without the protective plate will have the risk of deformation, leakage, and explosion. Faced with fierce price competition, battery packaging companies are looking for cheaper protection circuits, and perhaps they will not use them to flood explosive malls with lithium-ion batteries. Of course, customers cannot judge whether there is a protective circuit board from the appearance, so it is best to choose a reputable merchant to buy.
4. Look at the brand
There are many brands of lithium batteries, but it is difficult to see the quality from the appearance. In this case, we have to do a little more homework before choosing, and check the manufacturer's information online. Generally speaking, professional manufacturers are more reliable than small workshops, and experienced manufacturers are more reliable than novices.
