 Vibration testPut battery on the platform of the vibrations machine, start the machine and adjust the frequency form 10 times per minute to 15 times per minute. keep it running for an hourCharacteristics keep stability
Leakage at high temperature testStored under temperature 50℃) for 10 daysNo leakage allowed
Over discharge

Test

After 2.0v end-voltage, continuously discharged for 5 hoursNo leakage allowed
