Nominal
Capacity |
≥25000mAh@ 0.2C Discharge |
Nominal Capacity refers to the capacity of
0.2C discharge with 2.75V cut-off voltage, after charging with standard method. |
Cycle Life |
≥ 300 Times |
One 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. |
