A good/charged battery will last the winter without much negative effect—the golf carts here in our association last years doing just that. Obviously, we charge them full before storage and disconnect the leads (through the "tow" switch).

In terms of "which" batteries to buy, I think a lot depends on how it's/they're used. We're on our 7th season with a single Interstate that only gets charged when underway (disconnected in winter), but we also only have a single 150 OB, basic 4-speaker stereo, GPS, and, sometimes, a 12v inflator. We are rarely out at night to use lights.

I looked into a solar charging system and dual batteries, but I just couldn't bring myself to spend the moolah.

I suspect we'll replace this with a new Interstate next season and just hope for five+ years out of each.
