Battery terminal cleaning and treatment

[Ralph Day]

Hi all
My almost 15 year old battery bank has a couple of terminals that are showing a little bit of corrosion. The plan is to shut down, clean and re-connect. I'm just wondering what others have done regards corrosion deposition prevention.

Grease? Vaseline? Dielectric grease? Some kind of automotive terminal protection spray?
In the connection contact area or just after/put over top of the various bits?

Thanks for any and all advice.

Hi Ralph,

I've had reasonable success with a spraycan of dielectric grease. It's pretty thin stuff, so it doesn't get between the lugs/terminal to obstruct conduction. That said, it seems those lugs eventually all corrode no matter what.

An electrician buddy of mine noted something not long ago: According to him bare copper lugs were much cleaner with no corrosion compared to tin-plated lugs that were all corroded in the same system. I've not put much research into this, possibly something in it to do with which metal is more 'noble' (so the other one corrodes and the copper stays nice). Needs a bit more thought...

I have a tube of something similar to this which I have used.
