Anything new in batteries for solar
I have four 31 size lead acid batteries. They are heavy and you only get to used half their capacity. Is anything come up recently that could be a reasonable replacement--probably lithium?

IMO lithium wins hands down in ALL categories except up front cash.
Still going to be lower cost in the full life cycle. Even then they can rest at any voltage so if it degrades to half capacity in 6,000 cycles (15 years?) you just add a second in parallel. They will not fight each other.
you're right about cost.. currently about 400% more expensive but
6000 cycles, hmm.. not in the commercial world.. where did you dream up that number ?
