Storage Guidelines
To maintain optimal battery performance, follow these storage guidelines:
• 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.
• DO NOT attempt to charge damp/wet mobile computers or batteries. All components must be dry
before connecting to an external power source
.
• Replace defective batteries immediately; using a defective battery could damage the Optimus 5900
RFID 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 Optimus 5900 RFID 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 Product Service
and Repair (page 10-1) 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.
