Internal Backup Battery
Located inside the terminal, the backup battery is a 3.6V nickel metal hydride (NiMH) battery.
The internal backup battery prevents the terminal from being reset when you remove the main battery pack. The backup battery
retains RAM data and allows the real-time clock to remain operational for up to 30 minutes. If the terminal is left without the main
battery pack for more than 30 minutes, the internal backup battery discharges and needs to be recharged to function according
to specifications.
retains RAM data and allows the real-time clock to remain operational for up to 30 minutes. If the terminal is left without the main
battery pack for more than 30 minutes, the internal backup battery discharges and needs to be recharged to function according
to specifications.
Note: Even if the internal backup battery fails, data and programs stored in Flash memory are not totally lost. However, the
terminal automatically cold boots when you install a fully charged battery pack and you need to reset the real-time clock.
Charging
The internal backup battery charges off the main battery pack and requires eight hours charge time to backup RAM data for 30
minutes. You can begin using the Dolphin terminal after charging the main battery for four hours; however, the internal backup
battery will continue to charge off the main battery.

battery will continue to charge off the main battery.
To ensure that the internal backup battery functions properly, maintain a consistent power supply for the first eight hours of
terminal operation. This power supply can be external power (using a charging peripheral) or an installed, charged battery pack
or a combination of both.

Guidelines
Follow these guidelines to maximize the life of the Dolphin’s internal backup battery:
•
Keep a charged Li-ion battery pack in the Dolphin terminal.
•
Keep the Dolphin terminal connected to a power source when the terminal is not in use.
Managing Battery Power
Data and files saved on the Dolphin terminal may be stored in RAM memory; therefore, maintain a continuous power supply to
the terminal to help prevent data loss. When you remove a battery pack, insert another charged battery pack in the Dolphin. If
the main battery pack is low, insert the terminal into a charging peripheral to power the terminal and begin recharging the battery.

the main battery pack is low, insert the terminal into a charging peripheral to power the terminal and begin recharging the battery.
Note: If the main battery is low and the terminal is in suspend mode, pressing the SCAN trigger does not wake the Dolphin
terminal; you must replace the discharged battery with a fully charged battery.
Default Low and Critical Battery Points
The Dolphin terminal ships with default low and critical battery points programmed in the following registry parameters:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\LowBatt]
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\CriticalBatt]
The Navigation bar at the top of the each screen displays battery warning icons when the main battery reaches the low, then
critical battery points.
critical battery points.
Note: Battery power warnings do not appear when the terminal is running on external power.
Registry Parameter
Description
LowBatt
Sets the Low Battery point. The default is 25% (Hexadecimal=19). This is the point at which the
user is warned that the battery is low; the user is notified only once for a low battery.
user is warned that the battery is low; the user is notified only once for a low battery.
CriticalBatt
Sets the Critical Battery point. The default is 10% (Hexadecimal=a). This is the point at which the
user is warned that the battery charge is very low. This warning is posted every three minutes until
the situation is corrected.
