An electric working machine includes an electric device, battery packs, and a controller. The electric circuitry includes external relays corresponding to the respective battery packs. The controller is configured or programmed to perform an external relay test process to examine whether contacts of a corresponding external relay which corresponds to a second battery pack to be connected to second or later are locked, and, in the external relay test process, if a voltage between the positive and negative external terminals of the battery pack is equal to or more than a threshold, determine that the contacts of the external relay are locked, and, if the voltage between the positive and negative external terminals of the battery pack is less than the threshold, determine that the contacts of the external relay are normal.
