7. Characteristics

7.1 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.

7.2 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

7.3 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)

7.4 Initial internal impedance

Initial internal impedance measured at AC 1kHz after Standard charge.

Initial internal impedance ≤ 45mΩ

7.5 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.
