Demineralised Water

[Monaro Pete]

Most know that the ice in your freezer is pretty much pure of minerals & so can be used in your battery. The ice is moisture taken from the atmosphere.

So the water collected by my dehumidifier should also be demineralised as the process is the same?????

Or am I wrong?

I used to use water from our condensing tumble dryer.

I used to pass it through a coffee filter paper to remove any "debris".

I can't remember where I got this idea from, but used it successfully for some years, until all our batteries became "maintenance free".

You are right but a final filter to remove debris if any would be a good idea.

Or you could just buy some instead of messing about with filters etc :hide:

Oh so wrong, yes it was distilled water till it got contaminated by bacteria, it is fine for the likes of a steam iron but never ever in a battery, Rick

Or just get some from work that they use for the forklift trucks

My battery is sealed, but I was just thinking about the water my dehumidifier produces which I just throw away.
It produces 3 litres before it needs to be emptied.

Then folk buy it for irons when they could use the dehumidifier by product

Get a two inch lift on your truck, that's a much better use of your time

I read it somewhere that people use it for the final rinse when washing a car as it does not leave watermarks and also in the screen wash bottle.

Now that is a good idea :thumb2

Boil it then to kill off the bugs ?

Pretty sure the Sulphuric Acid would kill most bugs.

Not worth the hassle and risk for me 25 ltr water less than £12 Rick

I was told that it picks up metal sulphates from running over the condenser fins, making it very bad for batteries, and since air is being pulled through the fins by the fan to cool them, it picks up all the dust particles in the area, so is anything but pure.

Only thing it is good for is watering the plants.

crazy is it not that you pay over £1.00 for Di water, almost as much as fuel, as it happens I have a still so could produce my own proper distilled water and it would not cost the 50p per Ltr that I can buy it for, but I really cannot be fussed, good point that Clive, I have used filtered rain water in the past but not from a roof with any metal on it, Rick

Distilled Water options

Most of my batteries are sealed so top can't be done.

Just one last thought what about RO water from your local Aquarist it can cost from£3 to £4 for 25 litres it is classed as Pure Deionised water.

Here's a useful paper on the negative effects of impurities in battery water:
