Half the car batteries were at 11v or more, so some likely have some life to them.

Anyone have a methodology to test capacity that doesn't involve deeply discharging the battery? Perhaps target a 75% voltage as the discharge cutt-off and extrapolate capacity from that?

Know where to get top dollar for the scrap value? I don't see batteries mentioned on the webpage of the local metal scrapyard, but it's also not on the prohibited list.
If a lead acid is below 11V its really not even on the scale anymore. Scrap them for lead for a good price. Its more than the $10/ battery core they give you. The local recycling place will take those batteries, aluminum wheels etc...
