Take a look here:
http://www.alton-moore.net/graphics/desulfator.pdf
It's got some information you might find useful.
It would do you plenty of good to get yourself a multimeter.
It's the kind of information I was looking for, I can now build my own! :biggrin5:

Bad boy 
Your liver needs sleep
Anywho, I think it works. It barely reached 6V before. After about 24-28 hours, took it off, went to Walmart and bought a digital multimeter, hooked it up, it went from 8V to 11V in no time.
On the other hand (^ post was written 30 minutes ago), once I put a 12V speaker on it, it immidiately dropped to 5V. Tried it again, 8V. So I THINK it worked, but it needs to stay on there a bit longer.

Well.... I guess I could say it works!
That along with a bitta topping offa fluids and such. Bought 5 batteries from eBay, 4 were discharged (got them to 70-90% of original capacity). And one measured 10V. Wouldn't power a 24V scooter motor at all...
I made sure it wouldn't power it, then tried a old speaker. It had a nice bounce, so it had hope
Added a bitta water, desulfated it, and charged it, did that again... then some EDTA water...
And then 13.07V, which dropped down to 12.5xV after a 5 second stand with a 55W light...
So yay it worked

Oscar, Kinda of interesting on this reviving sealed batterys and all but after doing all this work I think you need a real load test and not just some light bulb. My money says once you think you've fixed it put it on a load meter....See what happens.
Well today I thought to drain it
And what's weird is... well here's the whole skoop:
1) Lasted about 1 minute before dimming rather... well like at a 4V level.
2) Let it sit there (hey I wanted to drain it all!)
3) Out of nowhere after a couple minutes there's a small *poop* and the light goes up to FULL BLAST
Literally, as in it looked better than it was at full charge. And as good as a 13V measured battery on the same light.
So... weird battery.
