The alternator is overcharging. If its warranted still, I'd ask for replacement of the batteries as well, as consequential damage directly resulting from the faulty alternator.

If you don't get that charging voltage down, it will fry your new batteries too. AGMs too, only a bit slower.
You aren't gonna like the price of a "true" deep cycle AGM.
I got mine from an independent battery shop......at about $200 each.
NAPA wanted $300 each.
Call around to auto parts stores, boat dealers and battery specialty shops in your area. Even an RV dealer or two maybe.....but that would be my last choice.
