Precautions when using batteries
• Never use a charger or battery that is damaged in any
way.
• Use the battery only for its intended purpose.
• If you use the phone near the network’s base station,
it uses less power. Talk and standby time are greatly
affected by the signal strength on the cellular network
and the parameters set by the network operator.
• Battery charging time depends on the remaining
battery charge, the type of battery, and the charger
used. The battery can be charged and discharged
hundreds of times, but it will gradually wear out. When
the operation 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.
Disconnect the charger from the power source when it
is not in use. Do not leave the battery connected to a
charger for more than a week, since overcharging may
shorten its life.
• 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 because
the capacity and lifetime of the battery will be
reduced. Try to keep the battery at room temperature.
A phone with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Li-
ion batteries are particularly affected by temperatures
below 0°C (32°F).
• Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object like a coin,
clip or pen causes a direct connection between the +
and – terminals of the battery (metal strips on the
battery). For example, do not carry a spare battery in
a pocket or bag where the battery may contact metal
objects. Short-circuiting the terminals may damage
the battery or the object causing the short-circuiting.
• Dispose of used batteries in accordance with local
regulations. Always recycle. Do not dispose of
batteries in a fire.
