Educate me on 12 volt batteries

oldwizard asked what other spare parts we carry. The answer is "several," but a spare battery is not just a spare battery in case the first one dies. Instead, it is a "swap out" battery -- we know for certain that our main battery will need charging after a few days (unless we have sunshine).
So then we swap the old one out and put the new one in. It's not a matter of "if." The issue is "when."
For each trip, I alternate which one will be my main battery and which one will be the spare.
By the way, my very risk-averse method of battery maintenance sacrifices the Peukert effect -- if I were to hook the two batteries together, I'd more than double my capacity.
But then I would have to recharge both batteries at the same time.
With my "spare battery" strategy, I can take the discharged battery and my portable solar panel into a sunny place and recharge, even though the trailer is parked in deep shade (which is what we usually do).
