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.

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.

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%.
