I have not ordered a new battery yet. I'm hoping to open the camper once the temps get above 40 and calculate my electric usage for each power item. Then beside on what changes I can make and what size battery to order. I have a large group 31 on it now but the charge doesn't last long. :-
I cleared 17" of snow off the camper today so it will be a few weeks.
The price makes the decision easier, but I've considered a Blue Top.
My concern is discharge state or how much they can be discharged.
For deep cycle the 50% rule applies for best economy.
The biggest blue top has less capacity than a group 24 but that could be made up if higher discharge is acceptable.
What about voltage versus state of charge, is it the same as a wet battery? I know the blue tops are fully charged at 13.1V.
