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?

So get a battery warmer.
I wonder why the LiIon companies building these batteries for uses where they could face cold temps don't do the same thing they do for military applications. There they build in warmers and the micro controller in the battery determines when to apply heat and modifies the charge rate accordingly.
Pretty sure that's how the Li batteries in cars are handled. Rather sophisticated battery temperature management in the newer ones. Heating and Cooling too.
Apparently the Nissan Leaf got bit by high temperature issues in their early models; while the Chevy Volt and Bolts have more sophisticated temperature management and haven't had any problems.
But then cars are often plugged into shorepower when not driving, so it's easier to manage temperatures.
As for long term storage under freezing (or hot) conditions (3 months, pianotuna's scenario), the darn things are so light I would just remove them from the trailer and keep them in a temperature controlled environment and on some sort of maintenance charge.
