A battery test circuit for a heart pacemaker generates a signal which corresponds to the charge status of the pacemaker battery which is displayable in a manner which does not interfere with the normal pacing frequency of the pacemaker. A marking pulse is generated by the circuit at a chronological position between successive stimulation pulses which is dependent upon the charge status of the battery at the time the marking pulse is generated.
