H2O source for batteries?

Seems I remember the best water source for batteries is distilled water to keep the contaminents out.

What source do most of you use? I have used tap water without any known problems. Ours is reasonable quality and not too soft (based on how easily soap rinses off).

I thought about using the condensation off the dehumidifer that we run in the summer. But since it comes from the air and drips off the aluminum fins, I thought it might have some alum disolved in it.

Steve, I have used condesate from an AC, and I know of no reason not to use it. Aluminium is not soluble in distilled water. However, I get my wife to catch the ice and water as the refrigerator defrosts, and I use that in my car. I wouldn't use tap water, with it's dissolved minerals. Also, its only pennies to buy de-ionised water from the local pharmacist, and that's what I use in our Airstream. Nick.

You can buy jugs of distilled water from most any drugstore, like CVS, or Walgreen's. People use it for their contact lenses. I always thought the rule was "distilled only" for batteries......

Use distilled water, about 70-75 a gallon nearly anywhere, and cheaper than destroying a battery.

Is the water from the dehumidifier filtered clean so that no extra particles are in it? For .70, a gallon of distilled water seems like a cheap enough price to pay to ensure nothing extra is being deposited into the battery.

For me, a distilled water is all I use in any of my batteries and they have all so far lasted 5 or more years each!

Thank you guys for your replies.

I was trying to keep the 'inventory' down. But I think it's best to keep a gallon of CVS distilled water around to be sure not contaminated as John, Eric, and others have stated.
