Battery Conditioning/Calibration
Your ARMOR X10gx batteries are self-calibrating and do not normally require the conditioning
process. The only time DRS recommends conditioning/calibrating a battery is if you notice that
the charge levels reported by Windows or ARMORutils, or displayed by the battery gauge, are
consistently different from actual battery performance. This is because conditioning adds to the
charge cycle count of the battery.
Battery conditioning is a 3-step process consisting of an initial full charge, followed by a full
discharge and finally followed by a full recharge. Each step is documented in the Conditioning
Status panel of the ARMORutils Battery Conditioning window (see Figure 122).
Read the following cautions and notes carefully and follow the procedure in Table 33 to
condition a battery.
CAUTION!
If the internal battery temperature exceeds 45°C or drops below 0°C
during conditioning, the system will abort the conditioning process.
Do not restart conditioning until the internal battery temperature is
well within the above temperature limits to avoid another possible
abort.
CAUTION!
Ensure external power remains connected until conditioning is
complete. If you disconnect
external power during the discharge
cycle, conditioning will not abort immediately but will continue until
the battery reaches the 3% charge level, and then abort. If you are
operating on only one battery or the other battery is also low in
charge, you could risk an unexpected shutdown of the tablet.
NOTE
You must have external power connected to condition a battery.
NOTE
The conditioning process can take 10 or more hours
with two
batteries
. Ensure that external power remains connected for the
duration of the conditioning period.
