If it's at the altitude of the ISS, atmospheric drag will eventually slow it enough so that it will return to earth. Sort of, since it's pretty certain to burn up.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.

So I was right?

Well, for quite some time. It will continue in its orbit until it decays, but that won't happen too quickly.

You’re all wrong. When the astronaut nudges the battery, a quantic filigree will spontaneously generate between his space glove and the battery. As we all know, from being familiar with the Hyperdiconic Periflatic Contriboolean Effect, the result will be an interflerian tunnel reaction.
The upshot of all this will dominate the news cycle for about a week, but the astronaut’s wife will get a lovely commemorative plaque and a healthy insurance settlement.

No, would eventually fall due to atmospheric drag, probably take several years though

The burning, yes. But the orbit is a spiraling in over time, not straight down.

Right. It only appears to be moving straight down given my perspective as the pusher. Downwards is a term that generally means "towards the ground." But I understand we are both circling the Earth as that's happening.
The comment that confused me was Polymaths explanation where is it moves away from you but then appears to comes back only to fall back down later. Is that some kind of elliptical orbit that crosses your own at certain points?

Yes. Your push puts the battery into a slightly different orbit. There will still be the tangential velocity, but you have added a (small) radial velocity. The result is an elliptical orbit that initially goes slightly inside of yours, but then has to go back up, eventually intersecting at the point in the orbit where you pushed. There is another intersection point for the orbits, but the timing will be off.

But that is also the case for your own orbit if you don't do corrections.

The path of the battery will be behind me, since I'll be heading back to the airlock.
