Test Methods and Condition 

Criteria 

 

 

 

 

3.1

 

 

 

 

Over charge testing 

 

At 23±5, charging cells with constant current 3C to
voltage 10.0V, then with constant voltage 10.0V till current
decline to 0. Stop test till cells temperature 10
lower than
max temperature.

No somke or fire 

 

 

 

 

3.2

 

 

Over discharge testing 

At 23±5, According to the requirements of standard
charge, the cells will be discharge to cut-off voltage, then
connect with external load of 30 ohm for 24 hours

No fire ,and no smoke ,no leakage 

 

 

 

3.3

 

 

 

Short-circuit testing 

At 23±5, After standard charging, connect cells
anode and cathode by wire which impedance less than 50m
Ω, keep 6h.

No smoke or fire
