• 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.
• Misuse or use of incompatible phones, batteries, and charging devices could result
in damage to the equipment and a possible risk of fire, explosion, leakage, or other
serious hazard.
• 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 nearest Samsung authorized
service center. Always recycle. Do not dispose of batteries in a fire.
