Abstract: A terminal having a nut-positioning device. The terminal including a horizontal potion, a vertical portion and a nut-positioning device. The horizontal and vertical potions respectively have a round hole enabling the fastening device to pierce therethrough and the round hole of the horizontal portion is configured to lockingly joint the output end of a lead-acid battery via the fastening device, and the round hole of the vertical portion is configured to lockingly joint an external electrical component via another fastening device. The nut-positioning device has a pair of vertically paralleled supporting arms to vertically extend from both ends of the vertical portion, and a pair of correspondingly biased arms extend from the extreme end of the supporting arms, and another pair of correspondingly biased arms is extended from the lower side end of such supporting arms.

Abstract: The present invention provides with a terminal post capable of delaying acidification thereof, mainly referring to the surface of a terminal post being formed with a plurality of grooves or protruding rings, so as to enlarge the contact surface between the posts and resin filled in the interior of the lead-acid battery, for the purpose of avoiding or delaying sulfate solution to infiltrate towards the posts through capillary action, thus delaying the acidification of the terminal posts, as well as protecting the terminal posts and the lead-acid battery terminals, and decreasing the possibility of occurring short circuit by lead-acid batteries.

Abstract: A terminal having nut-positioning device, comprising: a horizontal portion, a vertical portion and a nut-positioning device, wherein the horizontal and vertical portions respectively have a round hole enabling the fastening device to pierce through, whereas the round hole of the horizontal portion is to lockingly joint the output end of a lead-acid battery via the fastening device, and the round hole of the vertical portion is to lockingly joint an external electrical component via another fastening device; the nut-positioning device has a pair of vertically paralleled supporting arms to vertically extend from both ends of the vertical portion, and a pair of correspondently biased arms extends from the extreme end of such supporting arms, and another pair of correspondently biased arms is extended from the lower side end of such supporting arms, thus a containing space is formed by the supporting arms and two pairs of biased arms extended therefrom; such containing space is used for containing the nut of a fa
