Really. Haven't we beaten this to death? Steam distilled will be as good as
you can practically get. If you're really anal, get triple distilled
deionized HPLC grade water from Fisher Scientific or similar. It'll probably
cost $50 a gallon, but hey... it's really pure H2O!

Steve, the steam distilled is as good as it gets unless you pay through
the nose for laboratory grade USP water. I have been playing with this
Hanna TDS meter that I am putting on my watermaker. It came with
calibration samples of USP water and a 1000 ppm TDS sample. I
calibrated zero ppm with the USP water and 1000 ppm with the other
sample then started playing with different samples. The kitchen faucet
read 190 ppm. A sample of grocery store distilled water was 15 ppm.
Less than 8% of faucet water.

Thanks for all the tips on finding distilled water for my batteries.

However, I still remain sceptical regarding the quality of the
supermarket
"distilled water".

In one store I found it labeled as "steam distilled" water but no
reference
to the TDS (total desolved solids).

In another store I found two brands of "distilled" water. One label
stated
that it came for "Portland water system, charcoal filtered, Reverse
Osmoses
or steam distilation." I many not have the wording exactly, but that
"OR"
worrys me. Else where on the label it states that it has less than 1ppm
solids.

The other brand only indicated that it came from a plant in New
Hampshire
and gave a 800 number. Surprisingly, I called it at 1700 Pac. time and
got a
real live and helpful person. He had to go check when I as what process
was
used to produce the "distilled water". Without any prompting, as to what
answer I wanted to hear, he came back on the line and told me it was
Steam
Distilled. However, I neglected to ask if he know what the TDS was for
this
product. I got the impression that he was just an answering service for
the
distiller and had to call someone for all technical matters.

I purchased a couple gallons of the product that provided the info on
TDS
(1ppm) but now I'm unsure of how high a TDS I should allow.. I have no
idea
where to have a sample tested of the other stuff..

Anyone have any idea of what would be exceptable for my $600+ battery
bank??
Perhaps I should call Trojan??

BTW. I had several gallon jugs of nice clean rain water. Well, after
sitting
on the shelf for 2 years, this water developed green algae bloom.. I
dumpted
it out but later, I realized I could have filtered it through coffee
filters.
