Although it does not really apply, I love a quote from a motorcycle
maintenance book I read (paraphrased, because I don't have it here to get
the exact quote)

"If you use distilled water you can expect the battery to last for 12
months, but if you use tap water it will only last one year"

I know motorcycle batteries are a completly different world, but I still
like the quote.

R.O. water has even lower mineral content than distilled water. It's
actually better for the battery, since it's the minerals that cause
the harm.

Which RO dealer told you that? No RO system can produce the TOTAL
dissolved solids of my commercial distiller at 3.8ppm. Hell, it's easy to
try. Take a glass of RO water....Drop a power cord into the water and
plug
it into the wall. Distilled water is an INSULATOR. WRJA-TV's television
transmitter puts 18,500VDC on the distilled water that cools their two RCA
Klystrons on UHF. Body current is in microamps....

Nope...doesn't wash. The only contaminants in distilled water are
distillable liquids like benzene and the other ...enes. This is why we
pass them through activated carbon which removes them by attaching their
ions....

Then there's the problem of bacterial toxins passing through the membrane
when the trapped bacteria break down in the water stream....a serious
problem RO would rather you didn't know about.

Biologicals don't survive 100C for hours....

Having had motorcycles since I was 17, I'd say that was a fair statement.
One year might be stretching it a bit...(c;

But, here, we're talking about deep cycle, truly rechargeable wetcells that
one can make last for 5 to 10 years, even under heavy use.

The problem is the ions in the electrolyte combining with the impurities,
say iron or some other metal in solution, in the tap water....eating away
at the available acid supply while not producing usable electrons and not
being recoverable....leading to boat batteries that last a year like cheap
motorcycle batteries...(c;
