A battery diagnosis apparatus is configured to perform a diagnosis process that determines whether a battery mounted on an electric vehicle is a normal product. The battery diagnosis apparatus includes a battery control unit. The battery control unit is configured to diagnose that the battery is not the normal product when one of the following conditions is satisfied: a voltage of the battery decreases to a lower limit voltage before a predetermined time elapses from a start of discharging of a current having a predetermined current value from the battery; and an output value from the battery during a period from the start of the discharging until the elapse of the predetermined time is equal to or less than a predetermined ratio of an output value to be outputted from a genuine, new battery during the period from the start of the discharging until the elapse of the predetermined time.
