Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out of your
battery’s performance.
ᮣ Use only Sprint-approved batteries and desktop chargers.
These chargers are designed to maximize battery life. Using
other batteries or chargers voids your warranty and may
cause damage.
ᮣ In order to avoid damage, charge the battery only in temperatures
that range from 32º F to 113º F (0º C to 45º C).
ᮣ Don’t use the battery charger in direct sunlight or in high
humidity areas, such as the bathroom.
ᮣ Never dispose of the battery by incineration.
ᮣ Keep the metal contacts on top of the battery clean.
ᮣ Don’t attempt to disassemble or short-circuit the battery.
ᮣ The battery may need recharging if it has not been used for a long
period of time.
ᮣ 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.
ᮣ Don’t store the battery in high temperature areas for long periods
of time. It’s best to follow these storage rules:
Less than one month:
-4º F to 140º F (-20º C to 60º C)
More than one month:
-4º F to 113º F (-20º C to 45º C)
ᮣ Never expose the terminals of the battery pack to any other metal
object. Always wrap it or place it in a plastic bag, whenever
transporting it.
ᮣ Never heat and never attempt to disassemble the battery pack, as
that could cause leakage of the caustic electrolyte. If the battery is
accidentally broken, avoid skin contact with the contents. In the
event of skin contact, wash the affected area immediately and
obtain prompt medical attention.
ᮣ Always turn your phone OFF before removing the battery pack,
and always use the battery pack for its intended purpose only.
