Pay attention to the battery identification, and the battery trademark should indicate the manufacturer's name, battery polarity, battery model, nominal voltage, trademark, etc. Sales packaging (such as 2 shrink films or 4 shrink films, or tag) should have Chinese address, production date and shelf life, or indicate the effective period of the shelf life and the number of the implementation standard (generally GB/T GB/T×××××××××). Don't buy products without Chinese factory name, production date and shelf life, shelf life and implementation standards.
