• Using batteries and chargers
For charging and recharging your phone battery, see “Charge your battery” on page 5.
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
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 NiMH batteries 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 Battery low is briefly displayed. When no more talk time is left, the phone will beep three times and Recharge battery is displayed. The phone then switches itself off.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged or worn out.
