Characteristics
Standard Charge
This “Standard Charge” means charging the cell with charge current 1300mA and constant voltage 4.2V at 25℃ for 3hours.
Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 520mA with 2.75V cut-off at 25℃ within 1hour after the standard charge.
Standard Discharge Capacity ≥ 2550mAh
Initial internal impedance
Initial internal impedance measured at AC 1kHz after Standard charge. Initial internal impedance ≤ 100mΩ
Temperature Dependence of Discharge Capacity
Capacity comparison at each temperature, measured with discharge constant current 520mA and 2.75V cut-off after the standard charge is as follows.
Charge Temperature | Discharge temperature | |||
---|---|---|---|---|
25°C | -10°C | 0°C | 25°C | 40°C |
Relative Capacity | 60% | 80% | 100% | 80% |
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 (=2550mAh) is 100%
Temperature Dependence of Charge Capacity
Capacity comparison at each temperature, measured with discharge constant current 550mA 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% | 80% |
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 (=2550mAh) is 100%.
