Learning About the Backup Battery
The NiCad backup battery provides protection for power surges, sags,
spikes, and dropouts. The backup battery includes these features:
• During a power loss, the terminal uses backup battery power to
continue operating for 3 seconds. If power is still not restored, the
terminal saves all data and turns off. However, if the backup battery
charge is low, the terminal cannot protect the data against a power loss
and turns off immediately.
• The backup battery is rechargeable. The power supply provides the
power to charge the backup battery when required with the terminal
turned on or off. The terminal continuously monitors the backup
battery voltage level and charges the backup battery whenever the
voltage level gets low.
• The backup battery will last for a minimum of 3 years before its capacity
is reduced. Battery life depends on the age of the backup battery, your
usage, and RF duty cycle factors. If you are using the terminal in
extreme environments (very hot or very cold), battery life will be
reduced and you may need to replace the backup battery more often.
Note: The NiCad backup battery is NOT user-serviceable. You must
return the Trakker Antares 2475 terminal to Intermec to replace the
backup battery.
• The backup battery will provide backup battery power for a minimum
of 2 weeks with a fully charged backup battery pack installed and no AC
power. If you plan to store the terminal for a long period of time, save
any data stored in RAM to another drive on the terminal.
If the backup battery is still providing power when you reconnect the
power supply and turn the terminal on, the terminal resumes exactly
where it was when you turned it off, or restarts your application.
Note: If the Resume Execution command is set to Allowed, the
terminal resumes the application when you turn on the terminal.
Otherwise, the terminal boots and the application restarts.
Charging the Backup Battery
The backup battery is shipped inside the terminal, but it may not be fully
charged. You must fully charge the backup battery after you install the
terminal.
Note: The backup battery charger operates from 0°C to 40°C (32°F to
104°F). If you continuously use the terminal in an environment that is
outside this temperature range, the backup battery will not charge. You
may need to protect the terminal and create an environment that is within
