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 Charging/Fault LED will flash at a 1-second rate. When the batteries are
fully charged, all five fuel gauge LEDs will be on steady and the Charging/Fault LED will be on
steady.
Battery Operating Time
Your ARMOR X10gx can operate on one or two batteries and can operate with a single battery
installed in either bay. The length of time your X10gx can operate on batteries alone before
needing a recharge is primarily determined by the following:
screen brightness (backlight) setting
wireless and GPS radio activity
utility and software applications that are currently running
battery temperature extremes
number of batteries (1 or 2)
remaining battery capacity
The total operating time for the ARMOR X10gx 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.
Battery Discharge
When two batteries are installed, the system draws power from the highest charged battery first
until it reaches the 10% charge level, and then switches to the second battery. When the
second discharged battery reaches the 10% level, the system switches back to the first
discharged battery.
NOTE
The total remaining % charge for two installed batteries is
determined by the following formula: Batt #1 % + Batt #2 % / 2.
When the total remaining charge of both batteries reaches the 5% level, Windows forces the
computer into hibernation to save your session and protect your batteries from becoming fully
depleted.
Any time you return and find your computer has shut itself down (placed itself in hibernation), it’s
a good idea to check the remaining battery charge level as soon as you power up to be sure
your batteries are not exhausted. If they are exhausted, the Charging/Fault indicator will flash 5
times when you press the Power button.
