Characteristics
Standard Charge
This “Standard Charge” means charging the cell with charge current of 1,375mA and constant voltage 4.20V at 25°C, 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 550mA with 2.50V cut-off at 25°C within 1 hour after the Standard charge. Standard Discharge Capacity ≥ 2,750mAh
Rated Discharge Capacity
The rated discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 2,750mA with 2.50V cut-off at 25°C within 1 hour after the Standard charge. Rated Discharge Capacity ≥ 2,668mAh (97% of 2,750mAh)
Initial internal impedance
Initial internal impedance measured at AC 1kHz after Standard charge. Initial internal impedance ≤ 45mΩ
Temperature Dependence of Discharge Capacity
Discharge capacity comparison at each temperature, measured with discharge constant current 2,750mA and 2.50V cut-off with follow temperature after the Standard charging at 25°C.
| Charge Temperature | Discharge temperature | ||
|---|---|---|---|
| 25°C | -10°C | 25°C | 40°C |
| Relative Capacity | 60% | 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 (=2,750mAh) is 100%
Temperature Dependence of Charge Capacity
Capacity comparison at each temperature, measured with discharge constant current 2750mA and 2.50V cut-off at 25°C after the Standard charge is as follow temperature.
| Charge temperature | Discharge temperature | |||
|---|---|---|---|---|
| 0°C | 25°C | 45°C | 25°C | |
| Relative Capacity | 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 (=2,750mAh) is 100%.
