• Battery charging time depends on the
remaining battery charge and the type of
battery and charger used. The battery can
be charged and discharged hundreds of times,
but it will gradually wear out. When the
operation time (talk time and standby time)
is noticeably shorter than normal, it is time
to buy a new battery.
° If left unused, a fully-charged battery
will discharge itself over time.
° Use only Samsung-approved batteries
and recharge your battery only with
Samsung-approved chargers. When a
charger is not in use, disconnect it from
the power source. Do not leave the battery
connected to a charger for more than a week,
since overcharging may shorten its life.
° Do not use incompatible cell phone batteries
and chargers. Some Web sites and second-
hand dealers, not associated with reputable
manufacturers and carriers, might be selling
incompatible or even counterfeit batteries
and chargers.
° Extreme temperatures will affect the
charging capacity of your battery: it may
require cooling or warming first.
° Do not leave the battery in hot or cold
places, such as in a car in summer or
120
winter conditions, as you will reduce the
capacity and lifetime of the battery.
Always try to keep the battery at room
temperature. A phone with a hot or cold
battery may temporarily not work, even when
the battery is fully charged. Li-Ion
batteries are particularly affected by
temperatures below 0 °C (32 °F).
° Do not place the phone in areas that may
get very hot, such as on or near a cooking
surface, cooking appliance, iron, or radiator.
° Do not get your phone or battery wet.
Even though they will dry and appear to
operate normally, the circuitry could slowly
corrode and pose a safety hazard.
° Do not short-circuit the battery. Accidental
short-circuiting can occur when a metallic
object (coin, clip or pen) causes a direct
connection between the + and - terminals
of the battery (metal strips on the battery),
for example when you carry a spare battery
in a pocket or bag. Short-circuiting the
terminals may damage the battery or the
object causing the short-circuiting.
° Do not permit a battery out of the phone
to come in contact with metal objects,
such as coins, keys or jewelry.
