Charge Status LED
Each charger bay has an LED to indicate the status of the battery.
battery chargingRed
charging completeGreen
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.
Amber
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 3.8V), 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:
battery at 3.8 V, ready for storageRdy
battery coldCold
battery warmWrm
battery hotHot

percentage of charge%
Charging or discharging may take several hours. The remaining time is dis-
played as Time to 3.8 V in the battery monitoring menu (instead of Time to
Full).
To exit storage mode:
1. Enter the utility menu by holding both arrow keys.
2. Navigate to the Storage Mode menu and press the SET key.
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).

Time to Full
Displays the time remaining until the battery is fully charged.
IMPORTANT: Battery might not be charged to full capacity if any of the fol-
lowing status indicators appear:
Cold
Charging stopped because battery temperature is too cold. Charging will re-
sume when battery temperature increases.
Warm
Battery charging to less than full capacity (not less than 75%) because of
elevated temperature. The amber LED will illuminate when charging has
stopped.
Hot
Charging stopped because battery temperature is too hot.
Battery Health
This displays the health of a selected battery as a percentage of the charge
capacity of a new battery. Charge capacity (battery life when fully charged)
will decline as a result of repeated charge cycles, age, or storage conditions.
Cycle Count
Displays the total number of times that the battery has undergone one full
count of discharge and charge. Recharging after discharging half way counts
as one half of a cycle. Recharging after discharging a quarter of the way
counts as one quarter of a cycle.
Charge Status
Displays charge as a percentage of the total battery capacity. Also displays
charge in milliampere-hours (mAh).
Batt.Temp. (Battery Temperature)
Displays both the battery temperature (in Celsius and Fahrenheit) and the
status, as follows:
[Normal]
Battery temperature = 0°C to 45°C (32°F to 113°F).
