| Anyone have any personal success or failure stories on using EDTA to
desuphate batteries? I've read the homepower and web articles, just
would like to have a bit broader base of experiences before I try it.

So she's back up to full capacity? Did she have warped plates when
the doctors overcharged her?

| Nope, she is now 86 and drives around the city doing
charity work everywhere. Says she feels as good as 16
years old. I didn't check to see if her virginity was
back.

| EDTA is a chelator that chelates metals, especially
calcium. Chelating means it bonds to a metal molecule
and makes it easy to remove or filter via your kidneys
or the rinse water from your battery cell. I have no
actual experience with battery "chelating" though.

| As I recall from college days (back in the dark ages) EDTA chelates with any
heavy metal- so will combine with any heavy metal in your battery- this
includes lead of which there is quite a bit in the average lead/acid
battery. I think you're wasting your time on this route. I have tried
methods where you can put sodium sulphate (sulfate) into a battery
electrolyte and charge gently for a day or so but never had much success
with this. Scrap the battery, recycle the lead and start again with a new
one.

Sounds more or less correct. What you may be missing is that the
sulphate is more "available" than the other forms of lead, making the
sulphate the first to go and exhausing the EDTA before it works
against the lead itself.
The documentation is out there (including by Richard Perez) that the
process can create an improvement. Since the EDTA is relatively
cheap, I'm going to try it as an experiment at least. Peering into
the top of the cells, it looks like I may have some mild warping of
the plates from the high charge rate <sigh>, so I may end up recycling
them anyway.

| I tried EDTA in a 8 year old set of 220 AH golfcart batteries about 15
years ago and was very disappointed. I couldn't tell any difference
after treatment.
There's a company that's called PulseTech that also claims to eliminate
sulfation. Unfortunately I haven't been able to detect that it works
either.

Thanks. The success stories are often what get circulated, and yet
there isn't as much buzz these days about the stuff. I wondered if
there might be some other experiences out there.

| I've just reciently built and used one of those desulfators on a marine battery.
After a few charge cycles, I can now get a full charge. The battery was left 6 months or so with out charging, and would not fully
charge. Capacity is around 85%.
There is however self dischare rate that is higher than before. Still experimenting.
Cheers

I've also had a positive experience with a "desulfator" circuit I built up.
I have an old starting battery that had been sitting for a -long-
time(few years?),and was pretty much "dead",it wouldn't even take a
charge,would draw no current.
So I connected a 12V "wall-wart" to the battery and desulfator and left
it for a month,and sure enough it started coming back to life!
Nowhere near it's rated capacity,but better than dead.
After it had re-gained enough life to take a charge and run the
desulfator for a while,I cycled it like that..
charge/desulfate(discharge)/charge/repeat.
After a few more charge/discharge cycles with the desulfator as a load
it would now run a headlight (both high and low beams) for a decent
amount of time.But still nowhere near rated capacity(but,remember it was
*dead* as a doornail before I started).
It will hold enough charge to run some lighting,or a radio,etc. for a
while,I'd guess.
Not bad for an otherwise scrapped battery. Atleast it's somewhat useful
now,-it will never start a car again though.
