1.5.1 Battery
Main Battery
ƒ This rechargeable 3.7 V/4000 mAh Li-ion battery pack serves as the main power.
ƒ Normally, it takes approximately four hours to fully charge the battery. The
charging time may vary by working condition.
ƒ During normal operation, the terminal can work for up to 16 hours.
Warning: Using backlight, wireless connectivity, and peripherals while on battery
power will substantially reduce battery life.
Backup Battery
ƒ The backup battery takes charge when the main battery is removed or drained out.
ƒ If fully charged, it will help retain data in SDRAM and maintain the system running
in suspend mode for at least 30 minutes without the main battery. In the meantime,
you have to replace the main battery as soon as possible.
Battery Charge
ƒ Initial Charging
The main and backup batteries may not be charged to full for shipment. When you
first receive the package, you will need to charge batteries to full before using the
terminal.
Note: To charge the batteries for the first time, it requires approximately 8 hours.
After the initial charging, it takes only 4 hours to charge the batteries to full.
Because the internal backup battery is constantly charged from the main battery, the
initial charging requires installing the battery pack to the terminal and then seating
the terminal in the cradle for charging. This will have both the main and backup
batteries charged at the same time.
Note: To charge the backup battery, make sure that you slide the DIP switch inside the
battery compartment to the ON position.
