car battery - really necessary to use distilled water??

Money saving tip: If you have a condensing drier you can get free distilled water from the water tank when you empty it.

Or a dehumidifier :cool:

Also, "distilled water" (while correct) isn't the best term to use.... It's "de mineralised water".

Ironing water is also "de mineralised water", but only use that stuff if it's pure and not perfumed.

Tap water varies in quality, in a hard water area you'll very quickly ruin your battery.

It is up to the person filling the battery what they want to put in it, I will go by manufacturers advice as that seems sensible to me, and therefore i would recommend that course of action where asked for my opinion, I am not saying not used distilled water will or won't have a detrimental effect, though I suspect that it may, otherwise there wouldn't be any recommendation.

Okay - were you hoping for a gold star? as I have run out, specially after having to give quite a few out during last week.........

This will be my last comment on this thread as I was told by my parents to never feed the troll.

Has your company ever used distilled water to do this?I just wondered how the 2 processes compared longevity wise.

some of our larger customers that are controlled by southern offices do use distilled water,however non have been using it long enough to know yet.
if we get to the estimated life expectancy then we are happy with that.

If you have to regularly top up a car battery = it is nearing the end of it's life and I doubt you will notice any difference using tap water. I would replace it with a sealed battery.

Two year old post (YAWN). OP has probably replaced the car by now?

not always true. some batteries exposed to long periods of high temperature will dry out.

I used tap water in a unsealed car battery that I had years back, it lasted a good 8-9 years until I got rid of the car with the battery.

However, my car battery now is the newer sealed type.

I have always found using tap water to be more than OK, it has never proved any type of problem to me, even through winter and it being a cheap-ish battery back then.

I would advise that anyone who still has a unsealed battery to use, tap water, as very few have had any problems doing such, if any, at all

I find when I check car batteries that have been in for a while that noone else has checked them (not even a garage doing a service) and they've run dry.

Distilled water is so cheap that I can barely see the argument to use tap water instead as a credible moneysaving method. Probably costs nearly as much to boil the tap water

Agreed, the water around here (Suffolk) comes out the tap in tattoo'd lumps, it's very hard, nobody I know of around here tops up a battery with tap water.

That said, one, this is a very old thread, secondly, it's just a car battery.
