A method for diagnosing a redundant power supply executed by a computer of an apparatus for diagnosing a state of a battery mounted on a vehicle, the method comprising the steps of: performing a discharge process for discharging a battery according to a predetermined discharge pattern; performing a deterioration diagnosis of the battery when the first information obtained by the discharge process satisfies a predetermined condition; estimating an internal resistance value of the battery based on the second information acquired at the time of performing the latest diagnosis satisfying the predetermined condition if the first information does not satisfy the predetermined condition; and determining a state of the battery using the estimated internal resistance value of the battery.
