Is the water collected from a de-humidifier suitable for use in batteries. If so why? It is not distilled nor is it de ionised. Thank you for the correct explanation.
IMHO and of course I will be told if I'm wrong, but form my school physics, the water is distilled, it in fact water which has been turned into vapour, (leaving behind the impurities) then condensed, so it is distilled and fine for batteries, I used it for years in my batteries when in the uk and a mate rented them out, I used to get a 20 litre container from him. The only problem I would be worried about, is it's acid content, from being in the air, (acid rain) but as it's sulphuric acid, I doubt it would make any fdifference to a lead, sulphuric acid battery, it certainly didn't hurt mine. In lancashire by the way we used to use hill stream water!
had a neighbour who topped up his truck batteries from the stream beside our house. when asked why, he explained that it hadn't run through any metal pipes so it was 'de-steeled'
Water condensed in this way is quite pure, and the levels of acidity or alkalinity will not matter in the slightest when put into a battery. Unless you are running a smelting plant or something in your cabin, I really wouldn't worry about the possibility of 'acid' water.
I would however be concerned about putting hill or stream water into the battery as mentioned elsewhere in the thread. I know the gut instinct is to think that because they are natural, they are 'pure', but they will actually have high levels of minerals in them, exactly the things that distillation or deionisation are designed to remove.
In fact you'd be better off using tap water, as at least it has been filtered to remove large particles.
Totaly agree. and it's certainly good enough for the Steam Iron. Don't try our stream water here though....rather more calcium than is good for your batteries.......or your iron.
