This has not been my experience. I’ve had multiple AirTags notify me multiple times over a period of months that I needed to change the batteries.
Maybe my batteries die completely before the second notification triggers.

Apartment living can be hell when there are neighbours who don't replace their smoke detector batteries. I can't fathom how people can sleep through this loud annoying chirp every thirty seconds. I certainly find it hard and my apartment is far enough away that it's hard to determine where exactly the chirp is coming from.
The thought of smoke-detector like beeping of airtags all over the place gives me the worst kind of creeps. Please don't give them ideas! Please!
