Gassing

Do flooded wet cell batteries only produce gas when being charged? Can they be charged outdoors and then placed inside a camper for use powering fans, etc. safely?

Tom,

You have never gotten a clear answer to your questions. So,
Yes, but very little.
Yes

More involved discussion:
=> Once most Lead/Acid batteries are charged, they pretty much cease outgassing. The problem is that the loose hydrogen can still be detected by sensitive instruments.
=> If you have finished charging and you give the jar a couple of minutes to let the H2 escape, it will.

I do suggest that if you are going to do this, you store and carry the jar in a marine style battery box. No matter what you do with anything but a sealed battery, there will be acid residue on the surfaces.

If L/A batteries could not be safely inside, sailboats would be in real tough shape.
