Main Battery
Except that Model 8000/8020 is powered by two AAA alkaline batteries, Model
8001/8021/8061/8071 is powered by a rechargeable 3.7 V/700 mAh Li-ion battery pack,
and it takes approximately two hours to fully charge it.
For power-saving purpose, always turn off the backlight while working in a well-lit area.
When the backlight is on for extended periods of time, the main battery will become low
sooner than expected.
The smart battery icon on the LCD screen shows the status of power consumption. There
are two ways to monitor a low battery charge or discharged battery from the screen.

Backup Battery
In addition, one 3.0 V/7 mAh rechargeable Lithium button cell on the main board retains
data in SRAM and maintains the running of the real-time clock and calendar. It takes at least
twenty-four hours to fully charge the backup battery.
For a fully charged backup battery, it can last for at least 30 days. However, it is not
necessary to fully charge the backup battery for the mobile computer to work.

Initial Charging
The rechargeable battery pack must be fully charged before using the mobile computer for
the first time. Because the internal backup battery is constantly charged from the main
battery, the initial charging requires installing the battery pack to the mobile computer and
then seating the mobile computer in the cradle for charging. This will have both the main
and backup batteries charged at the same time.
Note: For initial charging, it takes approximately 2 hours to fully charge the main battery.
