The method includes a process of (i) and a process of (ii) in this order. In the process of (i), the potential of a first anode and the potential of a first cathode are adjusted in an aqueous solution containing chloride ions so as to increase the concentration of free chlorine in the aqueous solution. In the process of (ii), the potential of a second anode and the potential of a second cathode are adjusted in the aqueous solution so as to decrease the concentration of free chlorine in the aqueous solution. The difference between the potential of the second anode and the potential of the second cathode in the process of (ii) is smaller than the difference between the potential of the first anode and the potential of the first cathode in the process of (i).

A method for testing a precursor of a secondary cell with high reliability and high efficiency to judge the precursor to be acceptable or defective. The current flowing when a test voltage is applied between a pair of electrodes is measured before an electrolyte is placed between the electrodes. If a current the current value of which exceeds a predetermined reference current value () is detected during the time from the start of application of a voltage to a normal secondary cell precursor until the current becomes constant, the precursor is determined to be defective.
