Car Battery Terminal Connector, Pure Copper Cable End Top Post Clip Positive and Negative Pole, Applicable to Automobile, Truck, RV Yacht Accessories -

Terminals get replaced for one of two reasons. Either the lead clamp has been done up so many times it no longer closes properly on the post, or the whole connection has furred up green and runs warm under load. Either way, the cheapest part in the engine bay is the one holding everything else up.

The two cone sizes, and what to measure

Published figures are a 19 mm tapered positive and a 17 mm tapered negative. Those are the numbers to hold a vernier against on your own battery, because post tapers are not interchangeable and a clamp cut oversize grips on a ring rather than across the face. Worth knowing before ordering: another copper terminal kit stocked here publishes 18 mm for its positive. Neither listing explains the difference and no standard is named against either figure, so measure rather than assume that one positive terminal is much like another.

The contents line does not add up

Read this part before ordering. The supplier's pack list reads two insulation sleeves, four terminal blocks and two anti-corrosion washers, and the terminals themselves are never counted anywhere in it. The title says positive and negative, and two sleeves plus two washers imply a pair, but nothing states it outright. If both polarities from one order matter to you, confirm with us first rather than opening the packet to find one clamp. The metal is copper, described by the supplier as pure, with no purity grade or plating detail given.

Before you fit these

• A battery post will happily weld a dropped spanner to itself, and the electrolyte behind it burns skin and eats clothing. No fitting procedure is invented here beyond what the source states. If a live post is unfamiliar ground, an auto electrician is the answer.
• There is no current rating in this data and none can be worked back from a material name. Sizing the terminal, the cable and the circuit protection to the actual load is the installer's job.
• Since no cable gauge range appears, check that your cable will physically fit the clamp before ordering.

Two published cone sizes, a copper clamp, and a contents list worth querying before you commit.
