Projecta BT142-N1 Negative Bolt Brass Battery Terminal, Blister of 1

Quick answer

The Projecta BT142-N1 is the Negative Bolt Brass Battery Terminal, Blister of 1. One negative bolt terminal in a blister pack, the BT142-N1 is the one to grab when a single clamp has corroded or cracked on the negative post.

Check polarity before fitting: this suits the negative post only.

Before fitting, clean any corrosion off the post so the terminal seats properly. Lugs sit on a 5/16 inch or 8 mm stud.

The bolt style holds ring lugs firmly with a nut, the usual choice where vibration is a concern. Material is forged brass, a solid choice for battery connections.

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

FAQ

Does the BT142-N1 blister hold one terminal or two?

One negative bolt terminal, packed on its own.

Doing this in the driveway, what stud size does the BT142-N1 have for ring lugs?

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

Before I order, will a negative bolt terminal fit the opposite post?

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

Before I order, replacing a corroded clamp with the negative bolt BT142-N1: anything to watch?

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.

Before I order, how do I stop the bolt BT142-N1 going green on the post?

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