Hi Matt et al, Sorry for missing my que to respond.
As mentioned, the big concerns is mineral content in the water which will adhere to the plate and "take the place" of a possible reaction site - thus reducing capacity. As you can imagine, water quality is a concern from both the input and output standpoint and we have an outside Environmental Consultant group review water (and air) quality 1/4ly. We are very fortunate that even untreated/ filtered, has negligible mineral content. I have never been in a battery plant that uses distilled water but (almost) all, I have seen, use a form of filtration / dionizing before use. Hard water is a definite no no! Jamie >>> "R.

We have hard water here too, good to know that our distilled water mania is not in vain.

The "best" one uses a manual water release on top of each cap; this prevents over-filling when (not if) something sticks. I have never used non-distilled water in a battery, but I have replaced a couple of banks that were wrecked by using well water with a high mineral content. Matt ---- "R.

I still use distilled H2O, myself BTW. Have you actually experienced ruined batteries from ionized or filtered H2O? Also, if you reread Jamie's previous response, it sounds like they aren't even using distilled H2O to build them either. Ray On Sep 3, 2008, at 7:15 PM, Matt wrote: This is a majorly bad idea! Tap water usually contains dissolved minerals that will screw up battery plates, reduce or increase conductivity and generally void battery warrantees. Am I correct about this Jamie? Matt ---- "R. Walters" <[EMAIL PROTECTED]> wrote: Some of the single point battery watering systems have a pressure regulator that plumbs right to the water tap with a small filter. Apparently we in the solar business are more anal about using distilled water than many other battery users.
