26. Batteries and Recharging

Batteries

Batteries with different capacities are available. They are all of the NiMH type. (NiMH stands for Nickel Metal Hydride.)

Compared to the commonly used NiCd (Nickel Cadmium) batteries, the NiMH batteries have a higher capacity and they are much more friend- ly to the environment.

Battery meter

The battery icon, on the right of the display, re- flects the state of charge of the battery attached to the phone.

Low Battery alarm

As a reminder that the battery soon needs re- charging or replacing, an alarm signal (a long beep) sounds and the message Battery low appears for ten seconds in the display.

In addition, the indicator light on the top edge of the phone starts blinking red. If the phone is left on, the low battery alarm will be repeated several times and, finally, the phone will turn itself off when the battery is no longer able to power it satisfactorily. It is not possible to turn the phone on again. Instead the battery must be recharged, or replaced with a charged one.

If the condition of a battery is very bad, the phone will turn itself off immediately after the low battery alarm is issued for the first time.

Low battery alarm during a call:

If the low battery alarm is issued when a call is in progress, you should end the call as quickly as possible. If the call continues, the phone will turn itself off after a short period.

Recharging a battery

Besides the charger delivered with the phone, there are a number of other chargers available that can be used to recharge a battery.

Some of these chargers are connected to the socket at the bottom of the phone, allowing the battery to remain attached to the phone.

Such a charger both recharges the battery and supplies power to the phone. The recharging is controlled by the phone, which must be turned on. To indicate that recharging is in progress, the battery icon in the display is filled and emptied continuously.

The indicator light on the top edge of the phone shows green constantly (instead of slowly blink- ing green) when the phone is powered via the socket at the bottom, to indicate that service is available from a cellular network.

Battery care and maintenance

A battery has a long maintenance-free service life if properly treated.

●A new battery, or an old battery that has not been used for a long period of time, needs to be recharged and discharged 2 – 3 times, to reach full capacity. To discharge the battery, operate the phone as usual until the low battery alarm is issued.

●Avoid recharging a full, or almost full, battery. If you have the opportunity, wait until the low battery alarm is issued.

●Do not keep a battery in a sunny place. Extremely high temperatures reduce the battery’s capacity permanently.

●Never let a battery get into contact with metal objects that may short-circuit the battery poles, for example a bunch of keys in a pocket.
