For me, when it comes to batteries, size matters. I get the largest (capacity specs) that will fit in the space allocated to the batteries. It is difficult to say if you should be looking for new batteries. Do you have a chassis disconnect switch? If so, make sure the chassis batteries are fully charged before the coach goes into storage. Once parked, turn the disconnect switch to off. The batteries should hold their charge for a couple of months. If they do not, then it is time for new batteries.
