1.4.2. CHARGE BATTERIES

Due to shipment, it is likely that the main battery and backup battery won't be fully charged
when you receive the package. Before setting the mobile computer to work, charge the
main battery to full by direct charging via a power adapter (with the help of a Snap-on
Charging & Communication Cable or Charging & Communication Cradle).
Some key facts about charging batteries:
Charging Time
 Main battery: It takes approximately 4 hours to charge the 3.3V, 3600mAh main battery, and
approximately 6 hours to charge the 3.3V, 5400mAh main battery. The battery charging LED
above the touch screen lights red or orange during charging (depending on the battery level at
the moment), and lights green when the mobile computer is completely charged. See
for details about the LED indicator.
 Backup battery: The backup battery is a 3.6V, 15mAh Ni-MH battery which is rechargeable by
the main battery. It takes around 36 hours to charge the battery to full, however it does not need
to be fully charged for the mobile computer to work.
Charging Temperature
 It is recommended that batteries be charged at room temperature (18°C~25°C) for optimal
performance.
 Charging stops when temperature drops below 0°C or exceeds 35°C. In this case the battery
charging LED will be continuously blinking in red.
Power Consumption
 When all radios (802.11 a/b/g/n, Bluetooth) are active on battery power, main battery level will
drop substantially.
 In order to prevent the system from shutting down due to depletion of the main battery, we
suggest that you keep a fully charged battery for replacement or have the mobile computer
access the radios on external power.
