Important Battery Information
• Note that 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 standby time) is notice-
ably 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 good operation times,
discharge the 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.
