8000 Series Mobile Computer

1.1 BATTERY

1.1.1 MAIN BATTERY

Except that 8000/8020 is powered by two AAA alkaline batteries, 8001/8021/8062/8071
is powered by a rechargeable 3.7 V/700 mAh Li-ion battery pack, and it takes approx.
two hours to charge it to full.
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.
Examine the level of the battery icon
Monitor voltage level (see

1.1.2 BACKUP BATTERY

The backup battery on the main board takes charge when the main battery is removed or
drained out. When fully charged, the 3.0 V/7 mAh rechargeable Lithium button cell helps
retain data in SRAM and maintain the running of the real-time clock and calendar for at
least 30 days without the main battery. In the meantime, you have to replace the main
battery as soon as possible. It takes at least 24 hours to fully charge the backup battery.
However, it is not necessary to fully charge the backup battery for the mobile computer
to work.

1.1.3 CAUTION OF LOW BATTERY CHARGE

The power source for the mobile computer to work can be alkaline batteries (2*AAA for
8000/8020) or the rechargeable battery pack (for 8001/8021/8062/8071). The alkaline
batteries or the battery pack also charges the backup battery on the main board so that
the data stored in SRAM can be retained properly. Therefore, when the main battery
charge goes low, you need to replace the alkaline batteries or the battery pack. For
8001/8021/8062/8071, you may charge the battery pack in the cradle as soon as
possible. Most of all, you should upload important data on a regular basis.
Warning: Data loss may occur with SRAM during low battery condition. Always save
data before running out of power or keep a fresh battery for replacement
(or 2*AAA for 8000/8020).
