Projecta BT14-P10 Positive Wingnut Brass Battery Terminal, Box of 10

Quick answer

The Projecta BT14-P10 is the Positive Wingnut Brass Battery Terminal, Box of 10. Marked positive, it is sized for the positive post; the two are not interchangeable.

Box of 10 positive wingnut terminals, so this one is aimed at workshops restocking the drawer rather than a single car. Marked positive, it is sized for the positive post; the two are not interchangeable. Before fitting, clean any corrosion off the post so the terminal seats properly.

Lugs sit on a 5/16 inch or 8 mm stud. A wingnut lets you fit and remove ring lugs by hand, which suits accessories that come off now and then.

Forged brass conducts well and copes with the heat and vibration of an engine bay.

After fitting, a thin smear of terminal grease or spray protector slows corrosion. If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one. Keep the positive covered so a spanner cannot bridge it to the body. Tighten firmly but do not crush the post; a lead post deforms easily. Measure the post and the cable before ordering; a terminal that is too big for the post will never clamp properly.

FAQ

Quick question: are all 10 terminals in the BT14-P10 positive?

All 10 are positive wingnut terminals, packed in one box.

Doing this in the driveway, will my 8 mm ring lugs fit the BT14-P10 stud?

The stud is 5/16 inch or 8 mm. Use lugs with a hole to match.

Doing this in the driveway, will a positive wingnut terminal fit the opposite post?

No. Positive posts are slightly larger than negative ones, so this positive terminal is sized for the positive post only.

Doing this in the driveway, when swapping to a BT14-P10, should I cut the cable back first?

Cut the cable back to clean, bright copper if the old end is green or black, then fit the new terminal and tighten it firmly.

Quick question: how do I stop the wingnut BT14-P10 going green on the post?

Once it is tight, a thin coat of terminal grease or protector spray over the joint slows corrosion.
