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. Use only manufacturer-approved batteries and accessories.
Buying the right batteries and accessories is the best way to ensure they’re genuine
and safe.
● Only use the battery with a qualified charger. Use of an unqualified battery charger
may present a risk of fire, explosion, leakage, or other hazard. If you are unsure about
whether a charger is qualified, contact customer support.
● Do not disassemble or open, crush, bend or deform, or puncture or shred the battery.
● Do not modify or remanufacture, attempt to insert foreign objects into the battery,
immerse or expose to water or other liquids, expose to fire, explosion, or other hazard.
● Avoid dropping the phone or battery. If the phone or battery is dropped, especially on
a hard surface, and the user suspects damage, take it to a service center for
inspection.
● Improper battery use may result in a fire, explosion or other hazard.
● Do not short-circuit a battery or allow metallic conductive objects to contact battery
terminals.
● Keep the metal contacts on top of the battery clean.
● Battery usage by children should be supervised.
Charging
● In order to avoid damage, charge the battery only in temperatures that range from
32° F to 113°(0° C to 45° C).
● Don’t use the battery charger in direct sunlight or in high humidity areas, such as the
bathroom.
● The battery may need recharging if it has not been used for a long period of time.
