Car Battery Terminal Connector Classification Kit, Pure Copper Negative and Positive Cable Ends with Plastic Cover, Applicable to Automobile, Truck RV Accessories -

The two posts on a car battery are not the same diameter. Positive is the fatter one, and a clamp cut for the other will never grip it across its full face. This kit deals with that by supplying both ends: a red-cased positive at 18 mm and a black-cased negative at 17 mm, in copper the supplier describes as pure.

Two posts, two diameters, colour coded

The published figures are 0.71 inch / 18 mm for the positive and 0.67 inch / 17 mm for the negative, one in a red plastic case and one in black. Those numbers are what to measure your own battery against before ordering, because the taper of the post decides whether a clamp bites over its whole contact area or only part of it. Partial contact is what produces a warm terminal, a voltage drop under load, and a crank that sounds tired on a battery with nothing wrong with it. The colour cases also remove any guessing about which one goes where when you are leaning over the bonnet.

Pure copper is the stated material, and it stays a stated material

The supplier gives pure copper, and adds that it connects better than other materials and offers better corrosion resistance. That sentence is the supplier's, carried over as written. No purity grade, no plating detail, no current rating and — more awkwardly — no cable gauge range appears anywhere in the description, which is basic matching information for a terminal. A metal is not an amp figure and nothing here turns one into the other. Nor is any comparison made against a terminal in a different alloy.

The contents list, and one word buried in it

Listed contents are a pair of terminals, red positive and black negative, along with two terminal blocks and two anti-corrosion washers. Sitting in the middle of that same line are the words "for Nissan", which appear nowhere in the title and come with no model, year or part number attached. It is repeated here because the source says it, not because it defines what these suit. Treat them as generic post terminals and match on the 18 mm and 17 mm figures instead. Beyond that the supplier lists vans, RVs, trucks, yachts and cars in general.

Key features

• Positive and negative in one kit: both posts covered without ordering twice.
• 18 mm and 17 mm: the two published diameters, sized to the two different posts.
• Red and black cases: polarity is visible at a glance.
• Anti-corrosion washers: two supplied, aimed at the white furring that forms around a post.
• Terminal blocks: two included alongside the clamps.

What's in the box

• 1 x red positive battery terminal
• 1 x black negative battery terminal
• 2 x terminal block
• 2 x battery anti-corrosion washer

Before you fit these

• A battery can deliver an enormous current into a dropped spanner, and the electrolyte inside it burns. Nothing beyond the supplier's own text is offered here as method, and an auto electrician is money well spent if this is unfamiliar work.
• Matching a terminal to the post, the cable and the current it will carry sits with whoever installs it. This listing carries no rating for any of that.
• Because no cable gauge range is published, confirm that the clamp will accept the cable you intend to run before you order.
• The "for Nissan" wording is unverified and unsupported by any part number. Do not read it as a fitment guarantee for a Nissan or as a restriction against anything else.

A matched pair with the two post sizes actually printed — check them against your battery, and check the cable before you commit.
