Abstract: The present invention provides a terminal, comprising the contact portion, the insert portion, the engaging portion, the joint portion for connecting the contact portion, insert portion and engaging portion, the stopper for fastening the contact portion, insert portion, or engaging portion on the middle cover of the battery; the contact portion provides external electric appliances with electrical connection through means of contact, the insert portion provides external electric appliances with electrical connection through means of insertion, the engaging portion fastens on the terminal post of the battery so as to transmit electricity from the battery by the joint portion to the contact portion and insert portion through the engaging portion; the present invention further provides a battery having the terminals, mainly utilizing a pair of the terminals as positive and negative electrodes, and the contact portions and the insert portions in a pair of the terminals are disposed on different sides of the batte

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.
