Items Test Method and Condition Criteria

Over-Charge Protection
 

 At 20±5℃ conditions,after full-charging the battery with 0.5C and set the constant current and voltage supplier with 2times of the nominal voltage and current, then load it to the battery for 8h.

The battery should be no leakage,deformation,smoking and explosion during the test processes.

Over-Discharge Protection

At 20±5℃ conditions, discharge battery to 6.0V with 0.5C constant current, then discharge with 30Ω loading for 24 hours. Check the appearance of battery.

The appearance is normal,
Noexplosion, No fire,
No smoking, No leakage.

Short-Circuit Protection

After fast-charging, use a cable of 0.1Ω resistance to short the battery for 1 hour. Then check the appearance of battery.
Cut circuit of resistance; test the battery’s voltage after charging with 1C constant current for 5 seconds.

The appearance is normal,
Noexplosion, No fire,
No smoking, No leakage.

 
 
It is forbidden to short-circuit batteries or batteries, and do not place multiple batteries in boxes or drawers at will to avoid shorting each other or by other metal objects.
It is prohibited to subject a battery or battery pack to mechanical shock.
In the event of leakage, do not contact the leaking liquid directly to the skin or eyes, if contact occurs, apply a large amount of water to flush the contact area.
Do not use non-special charging, which should be done in accordance with the manufacturer’s instructions.
Note the “plus positive ear” and “-negative ear “signs of the battery pack to ensure proper use.
Keep the battery pack clean and dry.
