Quite a few of us use the screw-type isolator. I do, because I often don't use the car for several days and the after-market alarm system tends to drag the battery down.
Last week I got back in the car at the supermarket and hey-presto!, the thing was dead as a door-nail. Not even my MR S can drag a battery down that quick. I fiddled with the isolator and off we went. The isolator was struggling to maintain a good connection.
So, if you're using one of these, I recommend getting some of this stuff. It's excellent.

Thanks for that Carolyn, it occurs to me I don't have any grease of any description on mine!

I wonder if Copaslip, which I have, has similar properties?

I would be cautious about using copper with lead and alloy. I would think a petroleum jelly would be better.
This is the description of the grease Carolyn suggested- Copper Grease Pasta Multi Purpose Electric conductive ANTI Seize
My guess would be that Copaslip would be a similar formulation.
But Tomo's word of caution could be valid as from what I remember about that branch of science is that dissimilar metals in an eletrolyte solution produce an electric current. But what that would mean on the terminal of a battery I really do not know.
My next guess would be that someone on here will know.
It's actually of quite a different consistency to Coppaslip. It also looks different. It is designed for use in such applications. As for electrolysis due to dissimilar metals, I dealt with this issue a lot during my years in the Solar industry. Copper doesn't like steel if water is present. Ally doesn't like steel very much either, which is why steel bolts seize in ally castings. Copper and lead would be closely equivalent to old fashioned lead plumbers' solder and copper pipe - not a problem at all.
The biggest no-no was copper fittings directly onto steel threaded pipe - corrosion guaranteed. This was overcome by putting a brass fitting in between. The isolator is brass.
There are quite a few products out there that do similar jobs. They can't all be wrong.
My guess about "someone" is correct, it would seem that steel ( perhaps the iron content ) is the least Noble, thank you C.
I probably ( certainly!) did not make myself clear. What I'm talking about is the screw which makes the connection. It's a brass screw with a rounded tip that locates into a brass plate in the isolator. Has nothing to do with battery terminals. (Though I'm positive that this stuff would be excellent on battery terminals.)
No you didn't s:wink: :wink: s:wink:
Use on battery clamp is indeed listed in its attributes.
