Using batteries and chargers

For charging and recharging your phone battery, see Charging the
battery on page 10.
• Use only batteries approved by the phone manufacturer and recharge
your battery only with the chargers approved by the manufacturer.
• A new battery's full performance is achieved only after two or three
complete charge and discharge cycles!
• The battery can be charged and discharged hundreds of times but it will
eventually wear out. When the operating time (talk-time and stand-by
time) is noticeably shorter than normal, it is time to buy a new battery.
• 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.
• For good operation times, discharge the NiMH battery from time to time
by leaving your phone switched on until it turns itself off (or by using the
battery discharge facility 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.
• When the battery is running out of power and only few minutes of talk
time remain, a warning tone is heard and
played. When no more talk time is left,
and a warning tone is sounded and the phone switches itself off.
• Use the battery only for its intended purpose.
• Never use any charger or battery that 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.
