2.4. BATTERY
The mobile computer is fed by two batteries, main battery pack and backup battery. The
main battery is removable and replaceable from battery chamber while the backup battery
is mounted on the main board inside the mobile computer.
When the mobile computer is shipped, the main battery is stored in a package separated
from the mobile computer, which keeps it in good condition for future use.
MAIN BATTERY
The main battery is a Li-ion battery pack that comes in two sizes, a standard 3.7V/3600mAh
pack and an extended 3.7V/4400mAh pack. Both types will take around 4 hours to charge
to full. The working time of the mobile computer varies by its working states. Under normal
operation, it works for at least 12 hours. An icon on Title Bar
helps monitor main battery
level. See Main Battery Level
.
See also Main Battery Setup
for the assembly.
BACKUP BATTERY
The backup battery settles on the main board inside the mobile computer. It is a 15 mAh
rechargeable Li-ion battery. When main battery is absent or depleted, backup battery takes
over to feed the mobile computer. Without main battery, a fully charged backup battery
retains the data in the DRAM and holds the system in suspension for 30 minutes(as long as
wireless modules are inactive).
The backup battery is rechargeable by the external power (through power adapter) or main
battery pack. It takes about ˈ8 hours to charge it to full. An
icon on the Title Bar makes
it observant that backup battery gets low. See also Backup Battery Level
