Samsung SCH-u740 Cell Phone User Manual


 
Section 13: Health and Safety Information 150
• Follow battery usage, storage and charging guidelines found in the user’s
guide.
• Battery charging time depends on the remaining battery charge and the type of
battery and charger used. The battery can be charged and discharged
hundreds of times, but it will gradually wear out. When the operation time (talk
time and idle time) is noticeably shorter than normal, it is time to buy a new
battery.
• If left unused, a fully charged battery will discharge itself over time.
• Use only Samsung-approved batteries and recharge your battery only with
Samsung-approved chargers. When a charger is not in use, disconnect it from
the power source. Do not leave 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.
• 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.
