warming first.
 Do not leave the battery in hot or cold places, such as
in a car in summer or winter conditions, as it 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 not work
temporarily, even when the battery is fully charged.
Li-ion batteries are particularly affected by
temperatures below 0
(32 ).
 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-circuit.
 Dispose the used batteries in accordance with local
regulations. Always recycle. Do not dispose of
batteries in a fire.
