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