More than likely, your detector going off is not due to off-gassing from your wet cells, but a low voltage warning.
Sounds like you're on the right track. You'll want to disconnect and let your batteries "rest" overnight.. then take a new reading. After that, you might re-connect, put a load on (maybe 5amps) and monitor continuously. That will give you a good idea of how well your batteries are holding a charge.
As for batteries.. in that class.. I would be looking more at the group 27 or group 31 battery. You'll get more bang for your buck. AGM's are really nice to just "set and forget", but I really don't think off-gassing is causing your alarm. As such, I don't think it would hurt to just stay with wet-cells and save a few bucks.
