Charging Batteries
Slide the battery into the charging bay until it locks into place. Charging begins
as soon as the batteries are inserted.
Recovering a Battery from Deep Discharge
A deeply discharged battery is one that has been discharged to less than 3.0
volts. When the charger detects a deeply discharged battery, it automatically
enters recovery mode, which charges the battery using a reduced current. A
red LED indicates recovery mode. If recovery is successful, the charger exits
recovery mode and charges the battery to capacity. If the battery cannot be
recovered in less than 30 minutes, the red LED turns off and charging stops.
Charge Status LED
Each charger bay has an LED to indicate the status of the battery.
Red battery charging
Green charging complete
Off battery inserted incorrectly or battery depleted below 3.0
volts.
Amber charging stopped at reduced capacity (not less than 75%
capacity) because the battery is too warm. To reach 100%
capacity, a battery must be cooled to below 45°C.
