Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out of your battery’s performance.
䢇 Recently there have been some public reports of wireless device 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 devices resulting from the proper use of batteries and accessories approved by
Sprint or the manufacturer of your device. Use only Sprint-approved or manufacturer-approved batteries
and accessories found at Sprint Stores or through your device’s manufacturer, or call 1-866-343-1114 to
order. 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.
䢇 In order to avoid damage, charge the battery only in temperatures that range from 32° F to 113° F (0° C
to 45° C).
䢇 Don’t use the battery charger in direct sunlight or in high humidity areas, such as the bathroom.
䢇 Never dispose of the battery by incineration.
䢇 Keep the metal contacts on top of the battery clean.
䢇 Don’t attempt to disassemble or short-circuit the battery.
䢇 The battery may need recharging if it has not been used for a long period of time.
䢇 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.
