Charging antimony-free VRLA batteries without float
Here is a proposed much lower float current method to charge non-antimony batteries. Supposedly better than traditional float. Low current float for AGM

Hi Jim;
As a hobby or test case I can understand your curiosity about your AGMs. Thanks for posting your details as the info is beneficial to any interested parties, including myself.
An AGM is pressurized. I do believe there is capacity loss in the same manner that a tire loses pressure simply by the movement of atoms. I believe that is baked into the design. However, to deliberately walk a high voltage tightwire that could possibly lose gas, means a loss of H and O that is not baked into the design, is asking for trouble. I trust my two MS PWM controllers, with temp comp, to work unattended every day.
If the valves are intact, it should be nearly impossible to reintroduce H2O because AGMs are watertight submerged to 30ft. Another plus in a marine use if there is a concern for Chlorine gas.
If the valves are broken, then you really don't have a proper AGM battery. Yes it has a-g-m but the chemistry is not to spec.
