just had an agm battery fail and had to open a window at midnight to get fresh air, the batteries are located under the bed in the Motorhome, turned Ctek charger off and called a sparky in the morning no suitable batteries in Roxby Downs so he is coming back tomorrow to isolate the failed battery and I will rely on the remaining 140 amp battery to I get home. Wasn't aware that a sealed ago can still give off fumes

No such thing as a "sealed" battery. AGMs are a category of "Valve regulated" batteries. They have a valve that opens if the pressure gets too high inside. That is to ensure that the pressure is released before the battery case explodes if something goes wrong.
All batteries should be in a compartment that is vented to the outside.
Cheers,
Peter

Yes that is true ! Any lead acid battery will gas if over charged or something goes wrong. An external vented compartment should be the norm not open under the bed.

Hi Graeme c

That is an interesting curiosity question but it has little useful relevance as any and every brand of battery can fail and at any age.
Cheers,

Thankyou Peter. I just installed my agm in our new van and forgot to seal it and vent it to the outside.
Another job!
Regards Tony.

Hi Grahem
The reason I would like to know the brand name, is that I, and perhaps others in the future, could avoid them
I have heard of some no name brand batteries failing early, but this is the first time I have heard of one gassing
