Maintaining the Dolphin’s Batteries 

There are two batteries in the Dolphin: 

Internal NiMH Backup Battery 

Located inside the Dolphin, this battery backs up the RAM and clock when the NiMH 

main battery is discharged or removed from the terminal. 

 

NiMH Battery Pack 

The battery pack is the primary power source for operating the Dolphin. 

Internal NiMH Backup Battery 

The Dolphin’s internal backup battery prevents the terminal from being reset if you 

need to remove and replace the main battery pack.  The battery retains RAM data and 

allows the real-time clock to remain operational for up to 30 minutes when the battery 

pack is removed.  If the internal back-up battery becomes discharged of power, it 

requires a minimum of 5 hours of charging time in order to perform and maintain the 

system as described above. 

The internal backup battery is charged by the Dolphin’s main battery pack.  If the 

terminal is left without the main battery pack for more than 30 minutes, the internal 

backup battery needs to be recharged.   

 

Follow these guidelines to maximize the life of the Dolphin’s backup battery: 

• 

Keep a charged NiMH battery pack in the Dolphin. The internal battery 

will prematurely discharge if there is not at least a partially charged battery 

in the terminal. 

• 

Put the Dolphin in the HomeBase when the terminal is not in use.
