Storing Batteries
To maintain optimal battery performance, follow these storage guidelines:
• Avoid storing batteries outside the specified range of -4° to 104° F (-20° to 40°C) or in extremely high
humidity.
• For prolonged storage, to maximize battery life, it is recommended that the battery be at a 40% - 50%
charge level, be removed from any device, and stored in a controlled temperature environment.
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.
• 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, please send it
to Honeywell International Inc. or an authorized service center for inspection. Refer to the Product
Service and Repair 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, please send it to Honeywell International
or an authorized service center for inspection.
Internal Backup Battery
Located inside the terminal, the backup battery is a 3.6 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
