No real category for this so putting it here:
I just got a call from a guy asking if I'd seen his batteries. He had "a bunch" stolen. Among them and the most identifiable were several "Ultra Power" and several deep-cycle marine batteries. There was also some stainless steel. From his location, they'll likely get sold in southern Maine or northern New Hampshire. If you see them, PM me and I'll pass along his name and town.
