Analysis on the purchase skills of lithium batteries

1. The external appearance refers to the appearance, craftsmanship, size and technology of lithium batteries. Check whether the shell stitch width is wide, whether there are burrs, whether there is oil stains, and the hand feels good. The advanced technology feels very comfortable. Through polishing, the rubber varnish material has a good hand feel and strong insulation performance. 2. See if you can know the capacity of the lithium battery without knowing it. It is likely to use the remaining battery or reassemble the remaining battery. The market is flooded with many low-cost lithium batteries. Whether to use recycled batteries or removed batteries, the price is of course cheap, but the lifespan is short and the quality is unstable. Careless use may damage the equipment and cause an explosion. 3. Look at the maintenance circuit of the characteristics of the lithium battery to solve the problem that the lithium battery must be added to the maintenance board, in order to prevent the lithium battery from overcharging, overdischarging and short circuit, if the lithium battery does not have the risk of deformation, leakage, and explosion of the maintenance board. Faced with fierce price competition, battery assembly companies are looking for cheaper maintenance circuits, may completely eliminate the equipment, and put a large number of potentially explosive lithium batteries on the market. Of course, in practice, consumers cannot distinguish and maintain circuit boards from appearance, so it is best to choose reputable merchants to buy. 4. Look at the brand There are many brands of lithium batteries, and it is difficult to see the quality from the appearance. In this case, everyone should do a little more homework before choosing, and check the manufacturer's information more online. Generally speaking, professional manufacturers are more reliable than small workshops, and those with long working hours are more reliable than those who have just entered the field.
