If you want to check the brand of lithium battery cells, you can use the following methods:
1. Anti-counterfeiting label: check the outer packaging of the battery core to see if there is an Anti-counterfeiting label Generally speaking, most brand name batteries will have anti-counterfeiting labels affixed to the seals of the battery case. the battery when they leave the factory.
2. Charging process: Observing whether the battery changes significantly during the charging process, if the battery is normal, there should be no obvious changes.
3. Discharge process: changes in discharge charge voltage. If the capacity of the lithium battery is wrong or the internal resistance is too large, the voltage will drop significantly.
4. Weight and thickness: Compared with other batteries of the same capacity, high-quality lithium batteries will have a poids more normal and a more appropriate thickness.
It should be noted that the above methods cannot completely confirm the battery brand. If you need to know the battery brand precisely, you can consult the relevant people or do other related tests.
