Perhaps it is a difference in cap design?
But the gas is able to escape these batteries while they are closed (which is the reason some people build enclosed battery boxes & vent them to the outside). The seal is not air tight. In fact electrolyte can seep out if the battery is not sitting upright.

The old style batteries had removable caps, but as far as I know they were vented. In fact I would recommend that you
not remove them while charging the battery. The reason being that while charging the electrolyte typically will bubble and spew minute quantities of acid out of the battery. At the very least this might result in rust from the unseen presence of stray acid.
You might want to check that there is the right level of electrolyte in the battery before charging it; but leave the caps on while charging.
