Terminal for lead-acid batteries having nut-positioning device

A terminal having nut-positioning device, comprising: a horizontal portion, a vertical portion and a nut-positioning device, wherein the horizontal (11) and vertical portions (12) respectively have a round hole (110,120) enabling the fastening device (20) to pierce through, whereas the round hole (110) of the horizontal portion (11) is to lockingly joint the output end of a lead-acid battery via the fastening device (20), and the round hole (120) of the vertical portion (12) is to lockingly joint an external electrical component via another fastening device; the nut-positioning device has a pair of vertically paralleled supporting arms (130) to vertically extend from both ends of the vertical portion, and a pair of correspondently biased arms (131) extends from the extreme end of such supporting arms (130), and another pair of correspondently biased arms (132) is extended from the lower side end of such supporting arms (130), thus a containing space (133) is formed by the supporting arms (130) and two pairs of biased arms (131,132) extended therefrom; such containing space is used for containing the nut (22) of a fastening device (20), thus the nut (22) is to be held without loosening, enabling the screw (21) of the fastening device (20) to easily joint the nut (22) and fasten together.
