The cost of building materials are still high so ...

I was tripping on the size thing. The deal is for what those are worth it to Recycling yard you could buy two to three concrete blocks with every one of them.....actually more than that ,depending on Weight. I think last 12 volt battery I scrapped I got seven bucks for. Maybe 10
I didn't even think about that exchange rate between cinder blocks and batteries. Great point!!
