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. The
Recovery icon is displayed next to the bay number on the home screen. If recovery is successful, the charger exits
recovery mode and charges the battery to capacity.
If the battery cannot be recovered within 30 minutes, an error message is displayed and charging stops. Remove the
battery from service and check with local vendor for proper disposal of used batteries.
When batteries are ready for storage, they should be removed from the charger and placed into a temperature controlled area. Recommended battery
storage temperature is 0°C (10°F) to 25°C (77°F).
