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 Centro devices
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 device’s manufacturer, or call
1-866-343-1114 to order. They’re also available at s
print.com—click Accessories under the
Shop & Browse menu. 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).
Caution
Do not turn on the HAC setting unless you use a hearing aid with a telecoil.
Using this setting without a hearing aid or with a hearing aid without a
telecoil may be harmful to your hearing.
