An automatic battery discharger and tester for recording the performance of a battery being discharged under a selected resistance load wherein the battery's current and voltage are continuously monitored and compared against preselected current and voltage values, and includes means for maintaining a constant discharge current by varying the load resistance in response to any deviations of the battery current against the preselected current value, and similarly includes means to disconnect the battery from the load and interrupt the test when the battery voltage drops below a preselected voltage value signifying the discharged state of the battery.
