Please help with New Battery Purchase

Thanks! I think I understand that the "group" is the physical size of the battery itself...is there another number I should be looking for...like what amp hour rating would you consider to be OK in a large battery?

I definitely prefer a sealed system....I'm terrible with maintenance. Good intentions and all, I'll even put it on the calendar, but in reality I'll add water once or twice, but after that...well, I'll be buying a new battery again. :) Not proud, it's just my truth.

I saw another post about adding a second battery and the issue of sufficient space came up...that would be an issue for me too...pretty tight in there and I just bought this thing....haven't even camped in it yet so I don't know that I know enough to be taking it to a metal fabricator to make a custom mount for a second battery.

Thanks for the advice, much appreciated!

Since this RV is new to you, it is unknown how you will be using it. Also since you want to eliminate maintenance, you will need an AGM or gel battery.

I would suggest you buy a single AGM battery that will fit in your available space. It will cost substantially more than a similar size flooded battery.

All batteries of any given size will have very similar amp hour ratings. The rating normally used for comparing deep cycle batteries is the 20hr rating.
