Summary:The invention discloses a test method for evaluating the quality of an electrolytic capacitor, and the method comprises the steps: for each of a plurality of electrolytic capacitors, taking at least three electrolytic capacitors of the electrolytic capacitor, charging the electrolytic capacitors, and enabling the voltage values of the electrolytic capacitors to accord with a preset initial voltage range; in the process, the currently reserved voltage value of each electrolytic capacitor is measured at least twice in sequence, two adjacent measurements are carried out according to a preset time interval, and after each non-last measurement, if the voltage value of the electrolytic capacitor deviates from the normal voltage range of the measurement, the voltage value of the electrolytic capacitor is determined to be within the normal voltage range of the measurement. If so, charging or discharging the voltage value to enable the voltage value to be within the normal voltage range of the current measurement; if
