Nominal Capacity |
90mAh@ 0.2C Discharge |
Nominal capacity refers to the capacity of 0.2C discharge with 3.0V cut-off voltage. |
|
4 |
Cycle Life |
≥500 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 3.0V The cycle life is the cycle times when the discharge capacity is about 60% of the rated capacity. |
|

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. |
|

Storage Temperature |
Less than 1 year: -5~25℃ |
Cells must be storied at 3.75V~3.95V. 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 3.75~3.95V. |
|
Less than 3 months: -10~40℃ |
