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 phones resulting
from the proper use of batteries and accessories approved
by Sprint or the manufacturer of your phone. Use only
Sprint-approved or manufacturer-approved batteries and
accessories found at Sprint Stores or through your phone’s
manufacturer, or call 1-866-343-1114 to order.
ⅷ They’re also available at www.sprint.com — click Accessories .
Buying the right batteries and accessories is the best way to
ensure they’re genuine and safe.

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.
