Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out of your 
battery’s performance.
ⅷ
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 Samsung-approved batteries and 
accessories found at Sprint Stores or through Samsung, or 
call 1-866-866-7509 to order.
