Beetles never had vented compartments. Audi used a battery with small
directly connected vent tube.
As for modern battereis, they really have not changed that much over the
years. Maintenace free normally off gas very little, epecially when only ued
for strting and only being float charged from the alternator. However, where
you can have a problem is when soemtihng goes wrong. Say you have a cell
short out. Now you you have 13.8 volts going into a 10 volt battery. Those
last 5 cells are going to boil and gas really bad. Where do you want the
fumes and liquid to go. A so called sealed battery is going to do the same.
Less available liquid but those pressure relief vents are going to open and
the thing will actualy squirt and spray. If you have the cover, get the
screws and fix it so the cover stays down. When needed, how much effort is
it realy to turn the seat around and remove 4 screws.
