The charger supplies 0.2C constant current until battery voltage reaches 14.4V,then be changed at constant voltage of 14.4V while tapering the charge current to less than or equal to 0.01C.Charging time is 5.0 hours in all.
Capacity
Within 1 hour after fully charged, discharged at 0.5C continuously down to 10.0V.
100% capacity
Within 1 hour after fully charged, discharge at 1.0C continuously down to 10.0V.
95% capacity
Cycle life
A battery unit shall be repeated 2500 charge/discharge cycles, charged at CC-CV(0.2C-14.4V) for 5 hours, discharged at 0.5C continuously down to 2.0V Cut-off Voltage, Measure discharge capacity.
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 0.2C to 10.0V.
