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
