Combining Dissimilar Battery ah?
I know there are a few people here with real-world experience with this, so I hope they chime in! QUESTION: With a small 12v AGM battery (33ah), I have the choice of paralleling a slightly larger ...

Gassing and out-gassing are two different things HTH John.
Gassing is normal part of lead acid battery recharging, On SEALED Valve Regulated Lead Acid Batteries there is chemistry inside the battery that tends to encourage the gasses to re-combine into water.. Thus the battery does not "OUT-GAS".
Out gassing (Where the battery VENTS those gasses to the outside is not normal on AGM or other maintenance free types. at least not in any quantity. Some out-gassing MAY occure but it should be minimal. Which is why you can use AGM's indoors safely I might add.. The path is convoluted enough that acid fumes are normally held in even if Oxygen and Hydrogen are not. And very little H2 and O2 escape as well.
Maintenance free are not quite as good at this containment, and thus should be installed outdoors away from delicate electronics
Flooded wet cells do not even attempt to contain it and thus MUST be outdoors out of contact with delicate electronics or in a box vented to the outside
