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.
