• 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 place the phone in areas that may get very hot, such as on or near a
cooking surface, cooking appliance, iron, or radiator.
• Do not get your phone or battery wet. Even though they will dry and appear
to operate normally, the circuitry could slowly corrode and pose a safety
hazard.
• 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.
• Do not permit a battery out of the phone to come in contact with metal
objects, such as coins, keys or jewelry.
• Do not crush, puncture or put a high degree of pressure on the battery as
this can cause an internal short-circuit, resulting in overheating.
• Dispose of used batteries in accordance with local regulations. In some
areas, the disposal of batteries in household or business trash may be
prohibited. For safe disposal options for Li-Ion batteries, contact your
