Demineralised Water

Monaro Pete · 04-06-2017, 07:05

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

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

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

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.
