  "description_excerpt": "This specification relates to a battery terminal.\n\nJapanese Unexamined Patent Publication No. 2016-167407 discloses battery terminal to be mounted on a battery post of a battery provided in a vehicle. The battery terminal includes a terminal body and a bolt/nut combination for fastening the terminal body to the battery post.\n\nThe battery body is formed by bending one metal plate and includes two C-shaped annular portions and two U-shaped bolt holding portions for coupling both ends of the two C-shaped annular portions. The battery post is inserted into the annular portions. The bolt then is inserted through the bolt holding portions and the nut is screwed onto the bolt. Thus, the two bolt holding portions move toward each other, and the annular portions are reduced in diameter to be fixed to the battery post.\n\nThe terminal body of the above described battery terminal may be deformed excessively if an excessive tightening torque is applied to the nut.\n\nA battery terminal disclosed by this specification is to be mounted on a battery post of a battery and includes a terminal body with arcuate first and second mounting portions arranged to face each other and to surround the battery post. A first fastening portion couples one end part of the arcuate first mounting portion and one end part of the arcuate second mounting portion, and a second fastening portion couples the other end part of the arcuate second mounting portion and the other end part of the arcuate second mounting portion. The first and second fastening portions include bolt accommodating portions.",
