Characteristics

1. Standard charge

This “Standard charge” means charging the cell CCCV with charge current 0.5CmA (1,250mA), constant voltage 4.2V and 125mA cut-off in CV mode at 25℃ for capacity. .

2. Rapid charge

Rapid charge means charging the cell CCCV with charge current 4A and 100mA cut-off at 25’C

3. Nominal discharge capacity

The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 500mA(0.2C) with 2.5V cut-off at 25’C within 1hour after the standard charge.

Nominal discharge capacity ≥ 2,500mAh Which complying to the minimum capacity of IEC61960 standard.

4. Standard rated discharge capacity

The standard rated discharge is the discharge capacity of the cell, which is measured with discharge current of 10A with 2.5V cut-off at 25’C within 1hour after the standard charge.

Standard rated discharge capacity ≥ 2,450mAh

5. Initial internal impedance

Initial internal impedance measured at AC 1kHz after standard charge Initial internal impedance ≤ 18mΩ

6. Temperature dependence of discharge capacity

Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the standard charge is as follows.
