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%.
