摘要
A backup battery for buffering the operating voltage of a circuit arrangement is realized by a battery combined with an electrically irreversible element established by a melt fuse to form a unit. When the irreversible element exhibits its original condition when monitored, it is placed into the irreversible condition and the point in time is stored. As a result of the positive identification of the point in time of the initial commissioning of the backup battery, a premature replacement of the battery before expiration of the guaranteed service life that may appear necessary due to security considerations is avoidable. In a specific development, reaching the end of the service life of the backup battery is marked by the irreversible element.
