Expectations for 6 volt batteries
We replaced our two 12V group 24's with two 6 volt golf cart batteries - 220 amp hours. We also have 270 watts of solar, a Trimetric monitor and a Progressive Dynamic 9100 converter with a Charge Wiza...

When we switched to 6v we thought we would get longer time than the 12v. Right now, if we were using the furnace at all, we would be lucky to get through one night."

There seems to be some confusion in last few posts.
Two group 24 12v batteries were most likely 75AH each for a total of 150AH. The new 6 volts when connected in series are 220 AH. First reason to use sixes since you get more AH in the same space.
Batteries in series do not prey on each other in storage, so the sixes can get through the winter (on disconnect) without charging if needed.
Did you actually use the furnace over-night and have dead batteries in the morning? The furnace uses 7 amps per hour and should easily get through the night. With your usage mentioned, getting through a 2 or 3-day weekend would be no problem.
My Trojan T105,s lasted 10 years, along with one Optima Blue Top (for Television). My new ones are Trojan T105's and one Trojan 80AH 12v (for TV). I have no problems with either and the slight loss in early capacity will never be missed.
As for Diehard batteries; all bets are off! I had one go bad in less than a year and would never get another.
