People screw up occasionally, and if the consequences are expensive
it's sometimes worth the recovery effort. The one use of EDTA I
really recall reading about was a solar guy called in to fix a totally
discharged battery bank. He claimed it worked well. Perhaps he
could have gotten equally good results just by flushing and replacing
the acid. Perhaps not.


He was probably laughing his way to the bank and didn't use EDTA at all
If the battery bank had stood discharged for only a day or so, all he would
have
needed to do is rewire the bank in parallel, charge it for a couple hours,
this
would get enough internal resistance in the bank so it could be wired back
again,
then charged normally without burning up the charger. I'm sure his bill to
the battery owner was substantial. ;-)

As told by the guy who wrote the article, this was an attack of
midwinter cabin fever, where the couple had an argument and
both stormed out of the place leaving the lights on until the
battery bank died. He was called in much later.

As I said, this stuff has been touted for a decade or so by people
who work with batteries pretty regularly.

At the time we replaced a battery bank, I considered trying it but
finally decided I wasn't up for a couple days of farting around with
lots of gallons of battery acid.

If I'd had more time than money and acess to some expertise I
might have given it a shot.

I'd really love to see some methodical testing. To date,
all I've seen is anecdotal evidence, but all of it positive.
