Protecting your battery.
For best battery performance, you should follow these
guidelines:
Only use Samsung-approved batteries and desktop
chargers. These chargers are designed to maximize
battery life. Using other batteries or chargers will
invalidate your warranty and may cause damage as
well.
To avoid damage, only charge the battery in
temperatures that range from 32° F to 104° F.
Do not use the battery charger in direct sunlight or in
high humidity areas (such as a bathroom).
Never dispose of the battery by incineration (fire).
Keep the metal contacts at the battery base clean.
Do not attempt to disassemble or short-circuit the
battery, as injuries or burns may result.
You may need to recharge the battery if it has not been
used for a long period of time.
Replace the battery when it no longer provides
acceptable performance. It can be charged hundreds
of times before it will need to be replaced.
Do not allow metal objects or liquids to contact or
short-circuit the battery terminals, as injuries or burns
may result.
To avoid damage, store the battery in temperatures
ranging from -4° F to 185° F, and avoid leaving the
battery unused for very long periods. Follow these
storage rules:
Less than one month:
-4° F to 140° F (-20° C to 50° C)
More than one month:
-4° F to 113° F (-20° C to 35° C)
