Test purpose:
The final test result requires that the battery cannot explode or catch fire; In addition, the battery should not smoke or leak liquid, and the battery protection valve should not be damaged. Test whether other electronic and electrical products can work properly under low voltage, or if they are damaged

According to the standard:
Meets standard: UN 38.3/UL 1642/GB 31241
