Test Methods and Condition

Criteria 

2.1

0.2C Capacity

After standard charging, rest battery for 10min, then
discharging at 0.2C to voltage 3.0V, recording the discharging
time.

≥300min

2.2

Cycle life 

Constant current 0.5C charge to 4.2V, then constant voltage
charge to current declines to 0.01C, rest 10min,constant
current 0.5C discharge to 3.0V,rest 10min. Repeat above
steps till continuously discharging capacity Higher than 80%
of the Initial Capacities of the Cells

≥300times

2.3

Capablity of keeping electricity 

20±5℃, After standard charging, rest the battery 28days,
discharging at 0.2C to voltage 3.0V, recording the discharging
time.

≥240min
