How to Tell When Batteries Have Finished
Charging
While the batteries are charging, the fuel gauge LEDs will light to indicate the current level of
charge and the amber battery status LED will be on steady. When the batteries are fully
charged, all five fuel gauge LEDs will be on steady and the battery status LED will be off.
Temperature Can Affect Recharging Times
DRS has included temperature sensors in the battery circuit to protect the cells when a high or
low temperature condition occurs. Recharging a battery under extreme temperature conditions
can force the charger to suspend charging until the temperature returns to a safe level. This can
occur if the internal temperature of the battery falls below -10°C (14°F) or exceeds 45°C
(113°F).
Battery Operating Time
The total operating time for the ARMOR X7 with two fully charged 2400 mAh batteries at a
nominal room temperature is approximately 4 hours. For a single battery, the operating time is
approximately 2.5 hours. Legacy batteries with lower capacity will have correspondingly shorter
operating times.
Operating times will vary depending on backlight setting (brightness), wireless and GPS radio
activity, Ethernet network activity, and utility and software applications that are currently running.
The operating time can also be reduced when the batteries are near the temperature extremes.
