Introduction to the purchase skills of lithium-ion batteries

Look at the appearance refers to look at the appearance, workmanship, size and craftsmanship of lithium-ion batteries. Check whether the shell seam is wide, whether there are burrs, oil stains, whether it feels good to the touch, advanced technology is very comfortable to the touch, through polishing, the rubber oil polishing material not only feels good, but also has a strong insulation function. . 2. See if the capacity is clearly marked. Lithium-ion batteries without clearly marked capacity are likely to be waste batteries assembled from scratch using inferior battery cells or recovering battery cells. The market is full of many cheap lithium-ion batteries, which are made by retrieving battery cells or disassembling battery cells. Although they are cheap, they have short lifespan and unstable quality. Careless use may damage the equipment or even explode. 3. The characteristics of the lithium-ion battery in the maintenance circuit determine that the lithium-ion battery must be equipped with a maintenance board to prevent the occurrence of overcharge, over-discharge and short circuit of the lithium-ion battery. The lithium-ion battery without the maintenance board will be deformed, Risk of leakage and explosion. Under the fierce price competition, various battery packaging factories seek lower-priced maintenance circuits, and perhaps omit this device at all, making the market full of lithium-ion batteries with a risk of explosion.
