Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out of your battery’s
performance.
ⅷ 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.
ⅷ In order to avoid damage, charge the battery only in temperatures that
range from 32° F to 113° F (0° C
to 45° C).
ⅷ Don’t use the battery charger in direct sunlight or in high humidity
areas, such as the bathroom.
ⅷ Never dispose of the battery by incineration.
ⅷ Keep the metal contacts on top of the battery clean.
ⅷ Don’t attempt to disassemble or short-circuit the battery.
ⅷ The battery may need recharging if it has not been used for a long
period of time.
ⅷ 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.
ⅷ 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.
