Extracting lead from car batteries?

I have a couple of battered old car batteries. There is no local scrap dealer that will take them so I was wondering if it would be possible to extract the lead myself and sell it for scrap. I have searched on google and cannot find anything about this and I suspect it would be dangerous and impractical. However I thought there's no harm in asking here. I was imagining that I could open the battery up and pour the acid into some kind of strong alkali, neutralising it to make it safe for disposal. But then, I certainly wouldn't like to try this without some advice first. Cheers! Pete

H202 production

Wondering if any one have come across a video showing the steps or know how to do this and how to extract H2O2 form the solution to make hydrogen peroxide like discribed from wikipedia article http://en.wikipedia.org/wiki/Hydrogen_peroxide#Manufacture i know i just cut and pasted to make it easer the history  barium peroxide with nitric acid. An improved version of this process used hydrochloric acid, followed by sulfuric acid to precipitate the barium sulfate byproduct.  Sodium peroxide also makes H2O2 Na2O2 + 2 H2O → 2 NaOH + H2O2 those are hard to come by for DIY and thought maybe this would easier  inorganic processes were used, employing the electrolysis of an aqueous solution of sulfuric acid or acidic ammonium bisulfate (NH4HSO4), followed by hydrolysis of the peroxodisulfate ((SO4)2)2− that is formed. peroxodisulfate commonly referred to as the persulfate ion
