Got my new (used) batteries!! Now, how do I rejuvenate them?

Woohoo! I got it hooked up and did not electrocute myself :B.

I hot a chaperone, just in case. My mom :B. And moms are great -- When I let out a 'Woo! 14 point seven zero! I rock, ' she said, 'You do.'

I started with the lowest battery, figuring it was in the worst shape in case I ruined it. It is happily sucking down nearly 29 amps.

I made an elaborate edifice if plastic junk to provide air circulation while keeping cars and water out.
