I don't worry about the AGM batteries at all. Just don't let them die, freeze, or overheat when charging, Location doesn't worry me either. I put my AGM in my trailer's tongue box, surrounded by miscellaneous spare parts and extra electrical cords (there's a plastic barrier separating battery from them). Though the top of the box is sealed with a foam strip, the rear of the box has an open flap where the cables enter. I have the AGM on a BatteryMinder trickle charger year-round (as are all my vehicle batteries); I have never detected any hydrogen discharge whenever I have opened the box. My HHR Panel has a flooded-flat-plate battery under the rear floor. Whenever I had to sleep in it (on icy nights at work, too far to make a round-trip home), I never detected any hydrogen from the battery inches from my nose, even while charging it all night with the vent-tube missing (never saw the need to replace it). And then there are the three Volkswagens I had, all with standard lead-acid batteries under the rear seat. I did detect hydrogen gas when charging them, but only when they were being charged too quickly. P.S. I never let anyone smoke in my VW's.
