Boiled water or distilled

Yep, wot he said.

No prob Phil (I don't pretend to have the final undisputable word!) but I agree, boiling won't remove the minerals. Usually tap water doesn't have too much in the way of minerals anyway though (it's safe to drink in Oz) - I certainly would recommend using bore water tho'

Bore water would be the worst to use, depending on its make up Timbo!! Michael

Oops, I meant to say "I certainly wouldN'T recommend using bore water tho'", as Michael pointed out, it would be the worst to use!

What a slip up...

I would not use tap water around Perth as most of it is bore water. I have heard from water authority workers the water is near black with minerals when it comes to the surface and then they filter it a bit. Still tastes like it has too much minerals. Many people in the northern suburbs are installing house under sink filter systems as the water is just too hard to drink.

There is no way I would put this in my battery. I would not even put it in my radiator. I would not even put it in my coffee. Dogs and cats probably develop calcium kidney stones from it.

Hi Bob,

Filtering only removes the particulates, it does not remove the dissolved solids. The main solid of concern is calcium as it reacts with the sulphuric acid to form calcium sulphate (gypsum). Once this is formed and coats the plates, your batteries are cactus!

Truly CACTUS.
Bite the bullet and get a reputable gel. Yea. I know they cost.
In the long run they are better off road

Just curious, but wouldn't water condensing over the evaporator be contaminated with a metal ?

Yeah I see your point! but then distilling water or boiling through a copper pipe would do the same. Unless they distill the water in glass.

Yep! Rain water every time - keep a couple of juice bottles of it in the garage, and the wife collects and uses it in the steam iron.
cheers
