Discharge
Nominal Capacity refer to the capacity of
0.2C discharge with 2.75V cut-off voltage,
after charging with standard method.
5 Cycle Life 500 TimesOne cycle refer to one charge period
and then one discharge period.
Test condition:
Charge: 0.2C to 4.2V
Discharge: 0.2C to 2.75V
The cycle life is the cycle times when
the discharge capacity is about 80% of
the rated capacity.
6 Self-discharge Residual Capacity>90%After standard charging, storied at
25°C±0.5°C for 30 days, then measure
the capacity as item 4.

Cells must be storied at 3.6V-3.9V.
During long period storage, cells should be
maintained every 90 days. The method
is to do a charge-discharge cycle with
standard method, then charge to 3.7—
3.9V.
