Rejuvenating old batteries

[Mackman]

Lots of u-tube videos out there of guys rejuvenating dead batteries. Anyone had any luck breathing new live into old batteries, and does it last? What methods did you use?

I have an old friend obsessed with this idea, and over the years, I've never seen him get more than a few weeks of (daily use) life from a lifeless battery. There have been many urban legends and modern-day youtube videos on this topic.

Considering the lead content in lead-acid batteries, they are a pain to dispose of. If there were some miracle cure for failing batteries, it should be common knowledge by this time, in our effort to make the environment better.
