• Avoid storing batteries outside the specified range of -4 to 140° F (-20 to 40°C) or in extremely high
humidity.
• For prolonged storage, it is recommended that the battery be at a 40% - 50% charge level, be removed
from the device, and stored in a controlled temperature environment. Following these
recommendations will maximize battery life.
Guidelines for Battery Pack Use and Disposal
The following are general guidelines for the safe use and disposal of batteries:
• We recommend use of Honeywell Li-Ion battery packs. Use of any non-Honeywell battery may pose a
personal hazard to the user.
• Ensure all components are dry prior to mating batteries with peripheral devices. Mating wet
components may cause damage not covered by the warranty.
• Replace defective batteries immediately; using a defective battery could damage the Dolphin terminal.
• Never throw a used battery in the trash. It contains heavy metals and should be recycled according to
local guidelines.
• Don’t use a battery in any other manner outside its intended use in Dolphin terminals and peripherals.
• Don’t short-circuit a battery or throw it into a fire; it can explode and cause severe personal injury.
• Excessive discharge damages a battery. Recharge the battery when your terminal indicates low battery
power.
• If you observe that the Honeywell battery supplied is physically damaged in some way, send it to
Honeywell International Inc. or an authorized service center for inspection. Refer to the Technical
Assistance (page 13-1) section of this guide.
• Although your battery can be recharged many times, it will eventually be depleted. Replace it after the
battery is unable to hold an adequate charge.
• If you are not sure the battery or charger is working properly, send it to Honeywell International or an
authorized service center for inspection.
Internal Backup Battery
Located inside the terminal, the backup battery is a 3.7V Lithium Polymer battery.
The internal backup battery prevents the terminal from being reset when you remove the main battery
pack. This backup battery retains RAM data and allows the real-time clock to remain operational for at
least 30 minutes (if fully charged beforehand). 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 (\\Honeywell\AutoInstall)
or on an optional SD card are not lost. However, the terminal automatically cold boots when you install a fully
charged battery pack and you will need to reset the real-time clock.
Charging
The internal backup battery charges off the main battery pack and requires 2 hours charge time to backup
RAM data for 30 minutes. You can begin using the Dolphin terminal after charging the main battery for an
average of 5 1/2 hours for a fully depleted battery; however, the internal backup battery will continue to
charge off the main battery. It takes less time to charge the main battery if the battery has some charge.
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.
