3 - 10 Dolphin® 9500/9550 Mobile Computer User’s Guide
Batteries
The Dolphin 9500/9550 features intelligent battery technology. It is comprised of 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 must be completely charged before using the Dolphin 9500/9550 for the first time.
Main Battery Pack
Use only the Li-ion battery packs provided by HHP. The use of any battery pack not sold/manufactured by HHP in the
Dolphin 9500/9550 terminal 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). They can be stored between -30 to 80°C (-22 to 176°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:
• Place the terminal in a HomeBase (page 10-7) or Mobile Base (page 11-4) that is connected to an appropriate power supply.
• Connect a charging/communication cable to the mechanical connector, plug the cable into the AC adapter, and plug the
adapter cable into a power outlet.
• Connect the terminal to the Mobile Charger and vehicle power port.
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 13-3.
• Place the battery pack in the auxiliary battery well of the HomeBase - see page 10-7.
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.
Purpose
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.
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.
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 using the Pocket PC time and date function; see Setting the Time and Date on page 2-10.
Guidelines
Follow these guidelines to maximize the life of the Dolphin’s backup battery:
• Keep a charged Li-Ion battery pack in the Dolphin. The internal battery prematurely discharges if there is not at least a partially
charged battery in the terminal.
• Keep the Dolphin connected to power when the terminal is not in use.
