The water probably has a lot of bugs in it, but would it be Ok to use in lead acid batteries? Got to be better than tap water.

While battery manufacturers recommend using distilled water, I have used tap water for the last 40 years or so and have had no worries at all, so using water from a dehumidifier can't be all that bad.

I don't think that the bugs will have drunk too much of the water :D but it makes sense to strain the water before use.

1213824 2011-07-02 04:44:00 Wish I'd thought of it when I last needed some. I also reverted to the tap water. The dehumidifier, apart from traces of dust should be great. Paul.Cov (425)

1213826 2011-07-02 19:12:00 You can buy distilled water for batteries from Supercheap

When I changed the coolant in one of the cars,was advised to use deionised water which also was available at Supercheap

Even topping up your coolant ,you should not use tap water either

1213828 2011-07-02 20:42:00 Though water becomes more pure, I think, if it's also deionized/filtered through a cationic exchanger, since some water can be soft or hard, depending on presence of certain ions. Some domestic water chillers seem to have filtering beads. kahawai chaser (3545)
