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?

N8GS, thanks for the detailed reply. It is not obvious to me what went wrong. Now you have the new batteries with a different charging routine, at least you don't need to figure out exactly what went wrong with the old ones.
Thats right I am moving on. I have only had the new batteries in for a few months but I can say that everything works better with the higher voltage. Our last little camping trip was just a 3 day weekend w/ DW's family. We were at a camp site with power but I didn't plug in, got the batteries down to 80% DOD and ran the microwave to see how it would do. Battery voltage dropped to 12.68 volts after 3 minutes with a 124 amp load, inverter was very happy with that (I asked it and it replied in a very low voice "Its good"). The real test will come in January when we are camped in Quartzsite, AZ. Last year we were there for 53 days, this year we might get to stay there a little longer.
