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 life-time 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 (32 )
   and above 45 (113 ).

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 back of 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-circuit.

Dispose of used batteries in accordance with local regulations. Always
   recycle. Do not dispose of batteries in a fire.
