RS31 Mobile Computer
2.1. BATTERY

Main Battery
The mobile computer is powered by a rechargeable 3.85V / 2960 mAh 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.
(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.
(4) When the mobile computer has been on backup battery for 30 minutes, the system will
shut down. Be sure to replace the main battery as soon as possible in order to avoid data
loss.
