3 - 10 Rev C Dolphin® 9500 Series User’s Guide
Batteries
Dolphin terminals feature intelligent battery technology. There are two types of battery power: the main battery pack installed in
the back panel and the backup battery located inside the terminal. They are designed to work together to prevent data loss when
the terminal is in use over long periods. Both batteries must be completely charged before using a Dolphin terminal for the first
time.
Main Battery Pack
Use only the Li-ion battery packs provided by Hand Held Products. The use of any battery pack not sold/manufactured by Hand
Held Products in Dolphin 9500 Series terminals will void your warranty and may result in damage to the Dolphin terminal or
battery.
The 7.4V, 14.8 watt hour Li-Ion battery pack is the primary power source for the Dolphin. The Li-Ion battery is designed to operate
in a temperature range of -10 to 50°C (14 to 122° F). For the location of the Li-Ion battery on the terminal, see Battery/Battery
Well on page 3-5.
Charging Options
When the Li-ion battery is installed in the terminal, use one of the following peripherals:
• Dolphin HomeBase (see page 12-1)
• Dolphin Mobile Base (see page 13-1)
• Dolphin ChargeBase (see page 14-1) or the Dolphin Net Base
• Dolphin Mobile Charger - connect the charger to the terminal and vehicle power port
Note: Make sure the mechanical connector on the terminal is properly connected to the peripheral and that the peripheral is
connected to the appropriate power supply.
When the Li-ion battery is not installed in the terminal:
• Place the battery pack in the Dolphin QuadCharger - see Charging Batteries in the QuadCharger on page 15-4.
• Place the battery pack in the Auxiliary Battery Well of the Dolphin HomeBase (see page 12-5)
Charging Time
The Li-ion battery pack requires four hours to charge completely.
Internal Backup Battery
Located inside the terminal, the backup battery is a 3.6 Volt nickel metal hydride (NiMH) battery.
The internal backup battery prevents the terminal from being reset if you need to remove and replace the main battery pack. It
retains RAM data and allows the real-time clock to remain operational for up to 30 minutes when the main battery pack is
removed. If the terminal is left without the main battery pack for more than 30 minutes, the internal backup battery needs to be
recharged to function according to its specifications.
Note: Data and programs stored in Flash memory are not lost even if the internal backup battery fails. However, you must reset
the real-time clock; see Set the Time and Date on page 2-9.
Charging
The internal backup battery is powered by the main battery pack. Therefore, charging the internal backup battery requires that
the main battery pack be installed in the terminal and the terminal be connected to a charging device.
The internal backup battery must be fully charged before using the terminal for the first time. The initial charge cycle takes
approximately eight hours. After that, if the internal backup battery becomes fully discharged of power, it requires a minimum of
10 hours of charging time to function normally.
Guidelines for Use
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. The internal battery prematurely discharges if there is not at least
a partially charged battery in the terminal.
• Keep the Dolphin terminal connected to power when the terminal is not in use.
Managing Battery Power
Data and files saved on Dolphin terminals may be stored in RAM memory, which does not persist through a hard reset. Therefore,
to help prevent data loss, maintain a continuous power supply to the terminal.
