Battery terminals vitality used to dive originate automobile.
Battery terminals are used to attach leads to the battery. A Broad change of battery terminal types exis. Automotive batteries and alkaline batteries (the tiny batteries that faculty flashlights) are the most commonly used batteries, and the types of terminals used by Everyone varies mostly by where they are located.
Top Post
The most universal terminal type for an automotive battery is the top publish. Two round, metal projections on the top of the battery are designed to occupation a cable clamp. The bad terminal is ofttimes a inconsiderable smaller than the beneficial terminal to diffenrentiate between them; the negative terminal is normally labelled with a minus letter or a brunet plastic comprehend; persuaded terminals are labelled with the plus letter and burgundy tabs. Top publish terminals come in two sizes: customary post terminals, where the categorical terminal is 20 mm and the antagonistic terminal is 16 mm; and pencil proclaim terminals, which keep a 15 mm positive terminal and a 13 mm abrogating terminal.
Side Post
The side advise type of battery as the brand implies, has the posts on the side of an automotive battery, typically on the contour of the battery near the top. The side publish type of terminal does not acquire a projection; instead it consists of a threaded socket where a bolt on battery clamps is inserted. Provided a bolt is reinserted or replaced, over-tightening is a danger. Using a torque wrench place to 6 to 8 foot-pounds avoids any hot potato.
Dual Terminal
Some lead-acid batteries come equipped with two types of battery terminals.
Cylindrical
Most household batteries have "flashlight" style terminals on either end of the cylinder. A small metal cap projects out of the top of the battery and is the positive terminal, while a flat metal base serves as the negative terminal. These terminals will connect with either springs or metal strips in the battery holder.Called dual terminal or dual advertise, this drawing has two indefinite variations. One variation consists of both top proclaim terminals and side publicize terminals. The other consists of top display terminals that are tapped so that a bolt-clamp can be inserted. A dual post or dual terminal design provides a choice in connecting the battery to the battery cables.
Snap and Spring
Some household batteries have both terminals on the top. Typical 9 volt alkaline batteries, which are used in smoke detectors and digital clocks, have snap terminals. The negative terminal has a hexagon shape, while the positive terminal is circular. Each of these terminals fits or "snaps" into a power connector that also has the exact same type of terminals, with each positive terminal snapping into the opposing negative terminal.
6-volt lantern batteries have springs for terminals, than can be attached with screw-type connectors or simple metal contacts.
