In order to improve the logging in of battery-operated mobile parts (MT) in base stations (BS) with a battery charging device (ALE) in telecommunications systems for wireless telecommunication so that a log-in standby state between the mobile part (MT) which is logging in and the base station (BS) can be automatically produced without the user of the telecommunications system having to execute existing described procedures, said log-in standby for a battery operated mobile part (MT) in a base station (BS) with a battery charger in a telecommunications network for wireless telecommunication is produced by means of charging contacts (LK-M, LK-M, LK-B, LK-B) of the mobile part (MT) and base station (BS), whereupon the log-in procedure is carried out via the aerial interface of the telecommunications system.

In order to create a method with which, independently of the technology of the batteries utilized, a constant overcharging of the batteries is dependably avoided, even given a different capacity, particularly given a value deviating from the original capacity, and, thus, a long service life of the batteries can be assured, it is provided that an initial charging phase of the batteries after initial insertion into the device up to full charging is provided, that, subsequently, the batteries are at least partly discharged and a value representing the previously drawn capacity is generated at every point in time, that this generated value is compared at the beginning of a renewed charging phase with a stored base value representing the duration of the initial charging phase, and that subsequent charging phases follow whose duration is equal to that of the initial charging phase when the generated value is less than or equal to the base value or that subsequently charging phases follow whose duration is determined dependent on the generated value, said generated value, over and above this, being stored as new base value when it is higher than the original base value.
