How to choose high-quality lithium-ion batteries?

release time:2022-11-07 Hits: Popular:AG11 battery

　　1. Check the appearance and packaging

　　First, it can identify the packaging and appearance of lithium ion battery products. Although ordinary products look deceptive, they can also be filtered out from the appearance of some defective products.

　　2. Compare components

　　The composition of lithium-ion batteries is proportional to the capacity. Suppose it is polymer lithium-ion batteries. If the composition is too different, the capacity will inevitably be lacking. However, some batteries have different capacities. In addition, the weight of the battery can be seen from the package. Assume that heavy people prefer high-quality lithium-ion batteries.

　　3. Test internal resistance and maximum current

　　In fact, the fastest way to test the performance of lithium ion battery is to test its internal resistance and maximum discharge current. High quality lithium ion battery, small internal resistance, maximum discharge current. Select the 20A range of the multimeter and directly short circuit the lithium ion battery with two electrodes. The current should be about 10A or higher, which can be maintained for a period of time. A good battery is relatively stable.

　　4. Working at the test site

　　During the charged operation of the lithium-ion battery, the electric pole that has been discharged for about 10 minutes is assumed not to generate heat, and the battery protection system is perfect. Generally, the quality of the lithium-ion battery with high-quality protection is better than that of the general lithium-ion battery
