1. Standard Charge

This “Standard Charge” means charging the cell with charge current 1475mA and constant voltage 4.35V at 25℃  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 590mA with 2.75V cut-off at 25℃  within 1hour after the standard charge.

Standard Discharge Capacity    ≥   2850mAh

3. Initial internal impedance

Initial internal impedance measured at AC 1kHz after rated charge.
Initial internal impedance    ≤   100mΩ

4. Temperature Dependence of Discharge Capacity

Capacity comparison at each temperature, measured with discharge constant current 590mA and 2.75V cut-off after the standard charge is as follows.
