Important Battery Information - Nokia 6188 Owner's Manual

Important Battery Information

• The battery can be charged and discharged hundreds of
times but it will eventually wear out. When the operating
time (talk time and standby time) is noticeably shorter
than normal, it is time to buy a new battery.
• Use only batteries approved by the phone manufacturer
and recharge your battery only with the chargers
approved by the manufacturer. When a charger is not in
use, disconnect it from the power source. Do not leave the
battery connected to a charger for longer than a week,
since overcharging may shorten its life. If left unused a
fully charged battery will discharge itself over time.
• (NiMH batteries only) For optimal operation, discharge the
battery from time to time by leaving your phone switched
on until it turns itself off. You can also use the battery
discharge feature of any approved accessory available for
your phone. Do not attempt to discharge the battery by
any other means.
• Temperature extremes will affect the ability of your
battery to charge: allow it to cool down or warm up first.
• Use the battery only for its intended purpose.
• Never use any charger or battery which is damaged or
worn out.
• Do not short circuit the battery. Accidental short
circuiting can occur when a metallic object (coin, clip, or
pen) causes direct connection of the + and - terminals of
the battery (metal strips on the back of the battery), for
example when you carry a spare battery in your pocket or
purse. Short circuiting the terminals may damage the
battery or the connecting object.
• Leaving the battery in hot or cold places, such as in a
closed car in summer or winter conditions, will reduce the
capacity and lifetime of the battery. Always try to keep
the battery between 59º F and 77º F (15º C and 25º C). A
phone with a hot or cold battery may temporarily not
work, even when the battery is fully charged. NiMH
batteries' performance is particularly limited in
temperatures below 14º F (-10º C). Li-Ion batteries'
performance is particularly limited in temperatures below
32º F (0º C).
• Do not dispose of batteries in a fire!
• Dispose of used batteries in accordance with any local
regulations.
