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 in less than 30
minutes, an error message is displayed and charging stops.
Storage Mode
When set to storage mode (Storage Mode = Store at 3.8 V), all batteries are
charged or discharged to 3.8 volts, which is ideal for long-term storage.
The charge status LEDs indicate the voltage state:
Red flashing = battery charging or discharging to 3.8 volts.
Amber flashing = battery voltage at 3.8 volts.
The following indicators appear on the home screen next to each bay number:
Charge Status LED
Each charger bay has an LED to indicate the status of the battery.

LED illuminates and the charge cycle begins.
3. Use the arrow keys to select Off.
4. Press the SET key to exit.
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).
