Characteristics
Standard Charge
This “Standard Charge” means charging the cell with charge current of 1,700mA and constant voltage 4.2V at 23°C, 0.02C(68mA) cut-off.
Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 0.2C(680mA) with 2.65V cut-off at 23°Cwithin 1 hour after the Standard charge.
Standard Discharge Capacity ≥ 3,350mAh
Rated Discharge Capacity
The rated discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 1C(3,400mA) with 2.65V cut-off at 23°C within 1 hour after the Standard charge.
Rated Discharge Capacity ≥ 3,250mAh (97% of 3,350mAh)
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 3,400mA and 2.65V cut-off with follow temperature after the Standard charging at 23°C.
| Charge Temperature | Discharge temperature | ||
|---|---|---|---|
| 23℃ | -10℃ | 23℃ | 40℃ |
| Relative Capacity | 40% | 97% | 97% |
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 (=3,350mAh) is 100%.
Temperature Dependence of Charge Capacity
Capacity comparison at each temperature, measured with discharge constant current 680mA and 2.65V cut-off at 23°C after the Standard charge is as follow temperature.
| Charge temperature | Discharge temperature | |||
|---|---|---|---|---|
| 0℃ | 23℃ | 45℃ | 23℃ | |
| Relative Capacity | 60% | 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 of the Rated discharge capacity(=3350mAh) is 100%.
