We've not bothered to recharge Odyssey AGMs on the big boat when stored on land over winter... ~4 months without any attention... no issues, batteries still almost fully charged after splashing in Spring.
Even our diesel tractor with a run-of-the-mill AGM (East Penn, I think) sits over the winter without needing recharging -- unless we have enough snow that it requires plowing (didn't this year).
I wouldn't try that with wet batteries, though...
