Ah. I see.

I'm sure I have that elbow lying around somewhere in my battery compartment. I just didn't know enough to look for it.

It's 'this' kind of simple (obvious, once you already know it) stuff I'm trying to help other newbies with, so thanks for letting me know.

I don't actually 'need' it, since I replaced my BMW-installed battery with a Duralast (whose venting is wholly different); but I want to add it to the DIY ...

My original battery has this little black plug for the vent hole on the negative side of the battery.
