furred up negative terminal on leisure battery

[hogggman]

hi all,
i`m intermittently losing all leisure battery electrics.i haven`t investigated in depth yet,but have notice a lot of furring/white crud around the negative leisure battery terminal,could this be the cause,or just because of a loose terminal?
thanks

Does sound like problem. If it were me, I'd remove both connectors & clean up each clamp & battery terminal with a small wire brush or some fine sandpaper. Then smear both surfaces with petroleum jelly (Vaseline) which will prevent futher oxidation, but without affecting the electrical conductivity. Good luck.

The sanding of the terminals will increase the conductivity of the connections too, but only temporarily unless the terminals are protected from the damp, as simon suggests....

I use copper grease, this helps to promote a good electrical contact.

Yip i use a little copper grease aswell, top tip tho don't leave the tin infront of your van trust me it makes a nasty mess when you forget it and drive over it

Doh! It's not exactly the cheapest grease in the world either cheffy...

That's true, it does go a LONG way! I bought the tin i have about ten years ago, and it'sstill nearly full! I'll lose it before i use it.
