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 on the Shopping tab at top, then look under Phones & 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)
