Using RS35 Mobile Computer
2.1. BATTERY
Main Battery
The mobile computer is powered by a rechargeable 3.8V, 4020mAh Li-Polymer battery
pack, and it takes approximately 4 hours to charge it to full from the power adaptor (for
the first time charging the main battery, please charge it for at least 8 to 12 hours).
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 3.7V, 100mAh
rechargeable Li-Polymer 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).
It also keeps Wi-Fi and Bluetooth connections for about 30 minutes in suspend mode
after the main battery is removed. The Wi-Fi and Bluetooth connections will resume
right after the main battery is installed within the time period the connection is retained.
The backup battery can be charged by the main battery or the power adapter, and takes
approximately 4 hours to charge to full under the condition that it is always be charged
except of power off and no external power.
RTC Battery
RTC battery is a 3V, 1mAh rechargeable SMT type Li-battery which takes about 12 hours
to be fully charged. RTC retention will be maintained for at least 72 hours when the
main battery is removed.
Warning:
(1) The battery cover must be secured in position with its latch locked.
(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.
(5) To avoid system crash, system will NOT resume from the suspend mode if the power of the
installed main battery is less than 10%.
