Characteristics
1. Standard Charge
This “Standard Charge” means charging the cell with charge current 1300mA and constant voltage 4.2V at 25°C for 3hours.
2. 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
3. Initial internal impedance
Initial internal impedance measured at AC 1kHz after rated charge. Initial internal impedance ≤ 100mΩ
