BATTERY
Main Battery
The mobile POS is powered by a rechargeable 3.8V / 4000 mAh Li-ion battery pack. 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 POS 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 POS 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 must be secured in position. If not, the mobile POS cannot turn on by pressing the
power key.
(2) For a new battery, make sure it is fully charged before using, and for the first time charging the
main battery, please charge it for at least 8 to 12 hours
(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 POS 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.
