Projecta BT14H-N1 Negative Heavy Duty Wingnut Brass Battery Terminal, Blister of 1

Quick answer

The Projecta BT14H-N1 is the Negative Heavy Duty Wingnut Brass Battery Terminal, Blister of 1. One negative heavy duty wingnut terminal in a blister pack, the BT14H-N1 is the one to grab when a single clamp has corroded or cracked on the negative post.

Heavy duty pattern, so it suits thicker starter and dual battery cable.

Positive posts are slightly larger than negative posts, so fit this one only to the negative side. Before fitting, clean any corrosion off the post so the terminal seats properly. Stud size is listed as 3/8 inch or 10 mm.

With a wingnut on the stud, lugs can be swapped without a spanner. Forged brass conducts well and copes with the heat and vibration of an engine bay.

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. Check the terminal again after the first week, as new cable can settle under the clamp.

FAQ

Doing this in the driveway, is the BT14H-N1 sold as one terminal or a pair?

One negative heavy duty wingnut terminal, packed on its own.

Before I order, will 10 mm ring lugs fit on the BT14H-N1?

The stud is 3/8 inch or 10 mm. Use lugs with a hole to match.

Fitting it myself, why does the BT14H-N1 only suit the negative post?

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

Fitting it myself, what makes the BT14H-N1 heavy duty compared with the standard wingnut terminal?

It is built for heavier cable, with a 3/8 inch or 10 mm stud, which suits 4WD, truck and dual battery work.

Fitting it myself, my old heavy duty wingnut terminal is cracked; can I just swap in the BT14H-N1?

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.
