Characteristics
Standard Charge
This “Standard Charge” means charging the cell with charge current 1100mA and constant voltage 4.2V at 25℃ for 3 hours.
Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 440mA with 2.75V cut-off at 25℃ within 1 hour after the Standard charge.
Standard Discharge Capacity ≥ 2150mAh
Initial internal impedance
Initial internal impedance measured at AC 1kHz after Standard charge.
Initial internal impedance ≤ 100mΩ
Temperature Dependence of Discharge Capacity
Discharge capacity comparison at each temperature, measured with discharge constant current 1100mA and 2.75V cut-off with follow temperature after the standard charging at 25℃.
| Charge Temperature | Discharge temperature | |||
|---|---|---|---|---|
| 25℃ | -10℃ | 0℃ | 25℃ | 45℃ |
| Relative Capacity | 60% | 80% | 100% | 100% |
Note: If charge temperature and discharge temperature is not the same, the interval for temperature change is 3 hours. Percentage as an index of the Standard discharge capacity(=2150mAh) is 100%.
