Important Safety Information
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. Sprint is not aware of similar problems with
Sprint PCS® phones resulting from the proper use of batteries and
accessories approved by Sprint or the manufacturer of your phone.
Use only Sprint- or manufacturer-approved batteries and accessories
found at Sprint Stores or through your phone’s manufacturer, or call
1-866-343-1114 to order. They’re also available at
www.sprint.com
click the
Wireless link under Personal, and then click Accessories under
Shop the Sprint PCS Store Online. 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
Sprint 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.
