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 manufac-
turer 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 acces-
sory available for your phone. Do not attempt to dis-
charge 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.
