Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out of your
battery’s performance.
ⅷ Use only Sprint-approved batteries and battery chargers. These
chargers are designed to maximize battery life. Using other
batteries or chargers voids your warranty and may cause damage.
ⅷ In order to avoid damage, charge the battery only in
temperatures that range from 32° F to 113° F (0° C to 45° C).
ⅷ Don’t use the battery charger in direct sunlight or in high
humidity areas, such as the bathroom.
ⅷ Never dispose of the battery by incineration.
ⅷ Keep the metal contacts on top of the battery clean.
ⅷ Don’t attempt to disassemble or short-circuit the battery.
ⅷ The battery may need recharging if it has not been used for a long
period of time.
ⅷ 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.
ⅷ Don’t store the battery in high temperature areas for long periods
of time. It’s best to follow these storage rules:
Ⅲ Less than one month:
-4° F to 140° F (-20° C to 60° C)
Ⅲ More than one month:
-4° F to 113º F (-20° C to 45° C)
