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
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 device. Use only
Sprint-approved or manufacturer-approved batteries and
accessories found at Sprint Stores or through your device’s
manufacturer, or call 1-866-866-7509 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.
䢇Don’t store the battery in high temperature areas for long
periods of time. It’s best to follow these storage rules:
䡲Less than one month:
-4° F to 140° F (-20° C to 60° C)
䡲More than one month:
-4° F to 113° F (-20° C to 45° C)

Disposal of Lithium Ion (Li-Ion) Batteries

Do not handle a damaged or leaking Li-Ion battery as you can
be burned.
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.
Radio Frequency (RF) Energy

Understanding How Your Device Operates

Your device is basically a radio transmitter and receiver. When
it’s turned on, it receives and transmits radio frequency (RF)
signals. When you use your device, the system handling your
call controls the power level. This power can range from 0.006
watt to 0.2 watt in digital mode.
