A method for producing a storage battery, the storage battery including:

• an encapsulated terminal comprising:
• a terminal portion having a plurality of bolt insertion holes bored in one or a plurality of directions, a nut insertion opening through which a nut is inserted, and a hollow in communication with the bolt insertion holes and the nut insertion opening,
• a pole portion coupled to a lower end of the terminal portion, and
• a plastic portion surrounding a circumferential surface of the pole portion;
• and
• the nut having at least one screw hole threaded in a direction coincident with the at least one or a plurality of directions, the method comprising:
• a step of fixing the nut by deforming the terminal portion with the nut being inserted through the nut insertion opening into the hollow and the at least one screw hole of the nut being in communication respectively with the at least one of the plurality of bolt insertion holes.
