BATTERY
 Main Battery
The mobile computer is powered by a rechargeable 3.8V / 3100mAh Li-ion battery
pack, and it takes approximately 4 hours to charge it to full from the power adaptor.
However, the charging time may vary by your working condition.
 Spare Battery
A spare battery pack is provided as an accessory. We recommend keeping a fully
charged spare battery at hand in order to replace the main battery when it is nearly
drained out.
 Backup Battery
Settled on the main board is a backup battery that keeps the mobile computer in
suspension when the main battery is depleted. The backup battery is a 60 mAh
rechargeable Li-ion battery, and can retain data in the DRAM for 30 minutes when it
is fully charged (as long as wireless modules on the mobile computer are inactive).
The backup battery can be charged by the main battery or the power adapter, and
takes approximately 3.5 hours to charge to full.
Warning:
(1) The battery cover must be secured in position. If not, the mobile computer cannot
turn on by pressing the power key or wake up by pressing the scan key.
(2) For a new battery, make sure it is fully charged before using.
(3) To avoid data loss, when replacing the main battery, make sure you replace it with
a well-charged spare battery pack. Always prepare a spare battery at hand,
especially when you are on the road.
