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