Characteristics
Standard Charge
This “Standard Charge” means charging the cell with charge current 1075mA and constant voltage 4.2V at 25℃, 0.02C cutoff.
Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 430mA with 2.75V cut-off at 25℃ within 1 hour after the Standard charge. Standard Discharge Capacity ≥ 2050mAh
Rated Discharge Capacity
The rated discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 2150mA with 2.75V cut-off at 25℃ within 1 hour after the Standard charge. Rated Discharge Capacity ≥ 2000mAh
Initial internal impedance
Initial internal impedance measured at AC 1kHz after Standard charge. Initial internal impedance ≤ 35mΩ
Temperature Dependence of Discharge Capacity
Discharge capacity comparison at each temperature, measured with discharge constant current 2150mA and 2.75V cut-off with follow temperature after the standard charging at 25℃.
Temperature Dependence of Charge Capacity
Capacity comparison at each temperature, measured with discharge constant current 2150mA and 2.75V cut-off at 25℃ after the Standard charge is as follow temperature.
| 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 Rated discharge capacity(=2000mAh) is 100%.
