In an electric battery, an electronic clock is integrated in the battery container in order to monitor battery functions. The frequency of the electronic clock is varied as a function of at least one characteristic value of the battery. In one embodiment, the frequency of the electronic clock increases with increasing electrolyte temperature and increasing deviation of the terminal voltage from the open-circuit voltage of the battery. Specifically, the electronic clock may be connected to a measurement probe immersed in the electrolyte through which voltage is supplied to the electronic clock and the battery temperature and the electrolyte level are measured. The electronic clock signals its stopping as soon as a pre-assigned nominal running time is reached.
