IV. Charging process and indicator
1. Li-ion battery
1) Constant-current charging: charging current is 800±200mA and the indicator turns red. The
battery switches to constant voltage charging when the voltage rises to 8.4±0.1V.
2) Constant voltage charging: with 8.4±0.1V voltage and indicator turns red.
3) Completed: battery voltage: 8.4±0.1V; the minimum charging current drops to 75±20mA; LED
indicator turns green.
2. Ni-MH battery
1) Fast charge: current: 850±100mA; LED indicator: red; switch to supplementary charging when
rate of temperature rise dT/dt=0.9～1/min or the temperature rises to 50℃.
2) Supplementary charging: charging current: 65±10mA; LED indicator: green; switch to trickle
charging if the supplementary charging time reaches or exceeds MTO.
3) Trickle charging: charging current: 25~35mA; LED indicator: green.
