34 Abstract of the Disclosure: In an arrangement which is for use in an electronic circuit controllably put into operation by a battery (20) and which is for indicating a consumption status of the battery, a measuring circuit (22) measures a total time interval of operation of the electronic circuit. A processing circuit (21, 27) processes the total time interval into a calculated status for the battery. An indicator (32) indicates the consumption status based on the calculated status. The processing circuit may comprise a memory (21) for memorizing various current rates which are used in the electronic circuit and on which an arithmetic circuit (27) calculates the calculated status. Alternatively, first and second measuring circuits (25, 26) may be used with first and second current rates memorized in the memory for the first and the second measuring circuits. Instead of the measuring circuits, a summing circuit may be supplied with a succession of the current rates repeatedly read out of the memory to sum up a total amount of consumed current consumed by the electric circuit. As a further alternative, a counter counts down to obtain the total time interval in response to a pulse sequence of a pulse repetition period variable in proportion to a varying level of electric current supplied from the battery to the electronic circuit.
