7. Characteristics
7.1 Standard Charge
This "Standard Charge" means charging the cell with charge current
1100mA and constant voltage 4.2V at 25℃for 3hours.
7.2 Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 440mA with 2.75V cut-off at 25℃within 1 hour after the Standard charge.
Standard Discharge Capacity ≥2150mAh
7.3 Initial internal impedance
