No, you don't replace the permanent batteries in these 10 year smoke
detectors, you toss the whole smoke detector and buy a new one. Heroic
efforts aside.

So you don't need to find the right battery.

FWIW many smoke detectors bought in the past 10-15 years (I dunno but
something like that) even with typical replaceable batteries have some
sort of timer in them so when they hit 10 years they begin beeping in
a slightly different pattern (like two short beeps every 60 seconds)
and replacing the battery doesn't help. It just begins doing that on
the fresh battery until you figure out that you need to toss the
detector and buy a new one.

Ran into that, looked it up on their web site as I was confused why a
new battery wasn't helping and they confirmed that means the detector
has expired buy a new one.

I assume these 10 year sealed smoke detectors somehow came out of
that.
