　　Don't you know how to choose lithium batteries yet?

　　1. Look at the appearance

　　Appearance refers to the appearance, workmanship, size, and craftsmanship of lithium batteries. Check whether the seam width of the shell is not wide, whether there are burrs, whether there are oil stains, and whether the hand feel is good. The advanced technology provides a very comfortable touch. The rubber oil polishing material after grinding has a good hand feel and strong insulation function

　　2. Compare weight

　　The weight of a lithium battery is directly proportional to its capacity. If it is a polymer lithium battery, if the weight difference is too large, the capacity will definitely be insufficient, but some batteries have their own capacity differences. In addition, the weight of the battery can also be perceived from the outer packaging. If it is heavy, it tends to be a high-quality lithium battery.

　　2. Check if the capacity is clearly labeled

　　Lithium batteries without clearly labeled capacity are likely to be waste batteries reassembled from inferior battery cells or recycled battery cells. There are many cheap lithium batteries on the market, all made from recycled or disassembled battery cells. Although the price is cheap, the lifespan is short and the quality is unstable. Careless use may damage the equipment or even cause an explosion.

　　5. Check the battery

　　Most of the battery cells used in lithium batteries are soft pack cells and 18650 cells, which are also common materials for lithium battery pack cells. Firstly, check if the battery is brand new, as there are some unscrupulous small workshops in the market that use waste batteries to make lithium batteries. Flexible lithium battery, also known as polymer battery, is a kind of battery with flexible electrolyte in the form of gel. It can be made into various shapes, with high battery safety and no explosion.
