I know nearly squat about batteries but I know how to groups.google. :)

The best threads I found about this are searching for
'sci.chem.electrochem.battery sulphate'. (Without the quotes.)

The best snippet I found was
http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=slrnah74se.4mv.Znospam%2BnoZs_0206%40hpb13799Z.Zboi.hpZ.com.invalid

Yup, they stand to make money if they can convince you.  :)

And they strike me as at least over-hype, if not shady:

''The Macbat battery regenerator is a unique and revolutionary
innovation, ... ''

1)  Their implementation may be unique, but the ideas, overall
techniques, etc. sure don't seem to be.

2) revolutionary?  Right.

This is another one of those gray areas where people seem to get
sometimes good results, sometimes not.  Every controlled (ie
scientific) study I've seen has shown inconclusive or outright
failure.

So if you can find one cheap (eg easily build the one mentioned in
another post, borrow or buy and return, or ???) or if you're
spending someone else's money (gov't job, perhaps?) then try it out.
Just don't bet your life on it working.

And others saying similarly that it's a tossup, that the best cure is
prevention.

Have a :) day!
