Full Charge

The charger supplies 0.2C5A constant current until battery voltage reaches 3.65V，then be changed at constant voltage of 3.65V
while tapering the charge current to less than or equal to 0.01C5A.Charging time is 5.0 hours in all.

Capacity

①Within 1 hour after fully charged, discharged at 0.5C5A continuously down to 2.0V.

³ 100% capacity

②Within 1 hour after fully charged, discharge at 1.0C5A continuously down to 2.0V.

³ 95% capacity

Cycle life

A battery unit shall be repeated 3500 charge/discharge cycles, charged at CC-CV(0.2C5A-3.65V) for 5 hours, discharged at 0.5C5A
continuously down to 2.0V Cut-off Voltage, Measure discharge capacity.

³ 80% capacity

Capacity retention

After fully charged, stored for 28 days at 20°C, then for 1 hour at normal temperature and continuously discharge at 0.2C5A to
2.0V.

Capacity retention rate ³ 95%
