The AGMs that are in it are more than twice the cost of any good brand lead acid battery and didnt seem to last very long. Makes me winder if AGM batterys are not a good choice where you cannot keep them on a charger or dont use the vehicle regularly.
Its probably the worst situation you can subject a battery to, inconsistent use, then 7+ months of dead storage with no access to charging.
I'm guessing the valet marinas sell a lot of batterys!
And at the same time how could they possibly plug in all those boats,,, It would be an impossible task.

Your should be fine. You should easily get a few more years out of your batteries. While not being continually charged, every time you run your boat you are charging them back up. At a discharge rate of 3% per month on your AGM batteries, as long as you are shutting your battery switch off when leaving it for an extended period you should be fine. Fully charge them before winter storage, pull off the negative cable and all should be OK to start in the spring even if you can’t recharge to 100%.
