Characteristics
Standard Charge
This “Standard Charge” means charging the cell with charge current 0.91A and constant voltage 4.2V 100mA cut-off at 25℃.
Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 4A with 2.5V cut-off at 25℃ within 1hour after the standard charge.
Standard Discharge Capacity ≥ 1250mAh
Initial internal impedance
Initial internal impedance measured at AC 1kHz after standard charge.
Initial internal impedance ≤ 30mΩ
Temperature Dependence of Discharge Capacity
Capacity comparison at each temperature, measured with discharge constant current 4A and 2.5V cut-off after the standard discharge is as follows.
| Charge Temperature | Discharge temperature | |||
|---|---|---|---|---|
| 25℃ | -20℃ | -10℃ | 0℃ | 25℃ |
| Relative Capacity | 60% | 75% | 80% | 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 (=1250mAh) is 100%
Temperature Dependence of Charge Capacity
Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the standard charge is as follows.
| Charge Temperature | Discharge temperature | |||
|---|---|---|---|---|
| 5℃ | 25℃ | 45℃ | 25℃ | |
| Relative Capacity | 80% | 100% | 95% | |
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 capacity at 25℃(=1250mAh) is 100%.
