the battery connected to a charger for more than a week, since
overcharging may shorten its life.
• Do not use incompatible cell phone batteries and chargers.
Some Web sites and second-hand dealers, not associated with
reputable manufacturers and carriers, might be selling
incompatible or even counterfeit batteries and chargers.
Consumers should purchase manufacturer or carrier
recommended products and accessories. If unsure about
whether a replacement battery or charger is compatible,
contact the manufacturer of the battery or charger.
• 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.
