Precautions When Using Batteries
. Never use any 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 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.
. 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 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 short-circuit the battery. Accidental shortcircuiting 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.
. Dispose of used batteries in accordance with local regulations. Always recycle. Do not
dispose of batteries in a fire.
