Charge Status LED
Each charger bay has an LED to indicate the status of the battery.
battery charging
Red
charging complete
Green
battery inserted incorrectly or battery depleted below
3.0 volts.
Off
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.

Inserting Batteries into the Charging Bay
Slide the battery into the charging bay until it locks into place. The charge
LED illuminates and the charge cycle begins.
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 automat-
ically enters recovery mode, which charges the battery using a reduced cur-
rent. 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:

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).
