Batteries are not sealed - they would pressurize as weather and altitude change. I sure would not want a pressurized box of sulfuric acid in my trunk. They are really just (owner) maintenance free.

Thanks for the info. Anyway, the automotive AGM that I have seen have vent ports... The article clarifies that These batteries utilize a valve-regulated design that prevents electrolyte leakage, making them safe to use in various applications.
So - some kind of pressure relief valve is present in a "sealed" battery. Should be safe enough...
If the battery has vent ports, plug one and run the vent tube to the other port.
I learned something new today!
