Caring for the Battery

Protecting Your Battery
The guidelines listed below help you get the most out of your battery's performance.
Recently, there have been some public reports of wireless phone batteries
overheating, catching fire, or exploding. It appears that many, if not all, of these
reports involve counterfeit or inexpensive, aftermarket-brand batteries with unknown
or questionable manufacturing standards. Qwest is not aware of similar problems with
Qwest phones resulting from the proper use of batteries and accessories approved by
Qwest or the manufacturer of your phone. Use only Qwest- or manufacturer-approved
batteries and accessories found through your phone's manufacturer, or online at
www.qwestwireless.com/accessories. Buying the right batteries and accessories
is the best way to ensure they're genuine and safe.
In order to avoid damage, charge the battery only in temperatures that range from 32°
F to 113° F (0° C
to 45° C).
Don't use the battery charger in direct sunlight or in high humidity areas, such as the
bathroom.
Never dispose of the battery by incineration.
Keep the metal contacts on top of the battery clean.
Don't attempt to disassemble or short-circuit the battery.
The battery may need recharging if it has not been used for a long period of time.
It's best to replace the battery when it no longer provides acceptable performance. It
can be recharged hundreds of times before it needs replacing.
Don't store the battery in high temperature areas for long periods of time. It's best to
follow these storage rules:
Less than one month:
-4° F to 140° F (-20° C to 60° C)
More than one month:
-4° F to 113° F (-20° C to 45° C)
Disposal of Lithium Ion (Li-Ion) Batteries
For safe disposal options of your Li-Ion batteries, contact your nearest authorized service
center.
Special Note: Be sure to dispose of your battery properly. In some areas, the disposal of
batteries in household or business trash may be prohibited.
