Jamie,
I suspect that most if not all Off-Grid clients have well water. My
question is what about domestic water systems that use a filtration unit to
get the water to pass potable test in order to get bank financing and a C of
O. Since we are involved in Green Building I make sure that all our clients
also install an RO (reverse osmosis) system for drinking water only. Not
being a water guru I'm unsure how this RO water would affect the batteries.
I can only say that the water tastes awesome. I do know that it does remove
any minerals or hardness and I'm told by more than one water company that it
is similar to distilled water. I have been using RO water in our battery set
here at the Design and Training Center since 2001. I have seen no ill
effects. Love to hear anyone else's 2 cents.

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!

Matt;
I've used the watering systems for years as well, but never the tap connect.
We have hard water here too, good to know that our distilled water mania is
not in vain.

Ray,
We sell plenty of watering systems, but none are fed from an actual
pressurized tap. 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.

I never used it, but Battery Watering Systems has used them for
years. The rep I talked to thought we in the solar biz were quite
cautious on this.
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.

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?

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.
