Measurement

(A) After standard charging, laying the

Battery 0.5 = 1. 0h then discharge at 0.2C to ending voltage, recording the discharging time.

(B) After standard charging, rest 5 minutes, the 0.5C discharge to ending voltage.

After standard charged, on-hold for 26 days, discharge with 0.2C to ending voltage, then measure the residual capacity of battery, and examine the recover capacity with 0.2C/0 2C  

3

Testing for cycle life

Capacity Standard capacity 92%

After charged with 0.1C current then discharged with 0.2C to ending voltage. On-hold for 1o0mins, hence as above testing features are to cycle for 1000 time

Storage performance

On-hold for 1 month capacity 92%

After standard charged, under 250, 5C, on-hold for month, then discharged with 0.2C to ending voltage, and measure residual capacity of battery

Over discharge performance

Short-circuit performance under room temperature

No fire, No exploding, No smoking obtained

No fire, No exploding, No smoking obtained

After discharged to the cut-off voltage, the battery shall be subjected to a short-circuit condition with a load of resistance less than 300 for 24 hour

After standard charged, put the cell/battery into the explosion-proof with glass cover to short the positive and the negative for the battery (the total impedance is less than 100m0) for 1 hour
