1.3.1 Battery
Main Battery
The 9500 terminal is powered by a rechargeable 3.7 V/4000 mAh Li-ion battery
pack. It takes approximately four hours to fully charge it. 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
A backup battery retains data in SDRAM and maintains the OS running in suspend
mode for at least 30 minutes without the main battery.
Note: It takes approximately 8 hours to charge the backup battery to full.
Battery Charge
 Initial Charging
The main battery must be fully charged before using the terminal for the first time.
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 main/backup batteries
charged at the same time.
Note: For initial charging, we recommend that you install the main battery to the terminal
and seat the terminal in the cradle to charge the main/backup batteries at the same
time. It requires approximately 4 hours to fully charging the main battery.
 Caution of Low Battery Charge
The battery pack is the only power source for the terminal to work. It also charges
the backup battery so that the data stored in SDRAM can be retained properly.
Therefore, when the main battery charge goes low, replace the battery pack with a
charged one or seat it in the cradle for charging as soon as possible. Always save
data before it is too late.
