Condensed water for Battery

paye

Does anyone know if condensed water can be bought to top up a car battery? Or is there no need to worry and simply use boiled & cooled tap water?

I think it has to be distilled water.

L1011

Distilled water - most motor factors and some older fashioned pharmacies will have it.

Nonoperational

Any motor factors. Boiled and cooled wont do the trick, its distilled to remove ions and salts boiling wont do that.

8vjohn

De-ionised water. As above, it can be bought in motor factors. Many people use rain water I believe

Also available in Halfords and in some Tesco stores.

defrost your freezer and the water you get will do for the battery, its pure

+1 for Tescos, in the computer, DVD, pottery, funnels, wierd section

What about all the vodka and tomato sauce I spilt in there???

'Condensed' water, would, in fact, still be water; just less of it.

Some crazy or not suggestions out there :eek:

You are looking for distilled water as some posters rightly point out. Available from a motors factor or from a chemist. It's cheap at only a few Euro for 5 litres. Or may I add my own crazy or not suggestion: just use the water from the reservoir from your condenser dryer

'Condensed' water would, in fact, still be water; just the same amount in a smaller space, or the same amount of space with a larger amount of water.

Damn, beat me to it!

I just use rainwater Just make sure the container you use to collect it is CLEAN, and put it into a glass container.

Many thanks - wow! you guys are clever. Course I knew the answer all along.

Well, ACTUALLY, "water" exists as solid water (ice), liquid water, and gaseous water (steam), all are water. So, the most "condensed" form of water is as you say liquid water, regardless of whether it has been distilled previously or not. Usually the solid state of a substance is the most dense (or condensed if you like), but water is peculiar in that it expands when solid and hence is less dense (ice floats on liquid water). Distilled water is more pure than deionised water and probably more suitable for a car battery.

So there!! :D:D:D:D:D:D:D:D:D

Yes uniquely, water expands when it freezes. This small and unusual fact is one of the things which makes Earth habitable. It expands and becomes less dense than water thereby floating on the top. If it became more dense, it would sink in our oceans and freeze the entire planet

How much water do you add to condensed water to bring it back to nornal?

Depends if the amount removed was by freeze drying or desiccation! But roughly 11%.

True that!

But does it not also have strange properties with regards to expansion within the first 3-4 degrees celcius?

OP, you could always distill your own water using a liebig condenser!


This takes me back to the oul secondary school physics days!
