Testing method

 

Requirements

 

 

7.1

 

Temperature   test

Fully charged at 25  ℃, use 1C   discharge current to measure

the capacity at different temperatures by cut-off voltage 19.25V. take   the capacity at 25  ℃ as standard 100%

25% (at) -20℃

60% (at) 0℃

96% (at) 60℃


 

 

7.2

Constant temperature and   humidity test

 

Maintain the battery at   40  ℃ and 90% RH for 96 hours

Capacity recovery rate 85%

 

 

7.3

 

 

Vibration test

Vibrate   the battery in three mutually perpendicular directions by the amplitude of   0.35mm, the vibration frequency of 10-55HZ in 10 times each, the frequency   changing rate is 1HZ per minute.

 battery No broken, no smoke,no fire, no leakage.
