Can i use group 65 batteries in place of group 31 . walmart maxx

[Rick Penick]

I have a 1997 Monterey it has been stored for a few years in RV park in white mtns az. I am up here to try get motorhome back to Tucson and looks like all the batteries are shot. I have two napa 7236 batteries group 31 and have threaded post. I have 4 6 volt orielly batteries gs100tj same as a gs2 they say 115 min on them. I have had excellent luck with the maxx batteries from walmart got 10 years out of the pair on my dodge cummins. I called the local walmart they havee a group 65 not a group 31 like the napa battery and it has regular post not threaded post. I was thinking of just getting post adapters and buying these as they have 3 year full replacement warranty i called napa they have 18 mo and some only have 12 mo. Plus walmarts are  everywhere. Same with the GS2 they are 98.00 oh and so is group 65battery 98.00 . Any advice or thoughts on this ?

Thanks in advance..

Rick,
The group 65 battery only has 850 cca. That's marginal IMHO. I've used O'Rielly's group 31 and had good luck with them in our Marquis. There is a store in Show Low with a $119 price and they have the threaded terminals. The extra $ is worth it IMHO.
