Every device in the world that uses CR2032 makes contact with the battery on the bottom and the outside edge. Since the bitter taste is only applied to the top of the battery, there's no reason for Apple to make the BS claim of the battery not working.

The only reason to attack this product is to cover your ass for not including it in the first place.
It did not work in my AirTags. It worked in my car fob, but not in the Airtags. Got some other Energizer ones that worked fine
 
strange? I use them on my airtags

image from google, Mine are the same coating around the edge
 
Replaced my AirTag battery today and it didn’t work. Googled why (actually DDG’d) and remembered reading about the coating. Lighter fluid took it off easily.

I just use energizer and I've had no problems with mine.

It's like drain cleaner that most people have in the house. Yes it's extremely dangerous so keep it out of reach of children!

i don't have any ***** children. useless feature for small percentage of households. packaging is difficult to open anyways.
Me either. I think a better child safe package would have been a better solution but that doesn't stop careless people from leaving old batteries out or giving them for their kids to play with
 
Can't parents just do their jobs as parents, and watch their kids to make sure they don't eat batteries? Am I weird to think that's not asking very much?
Of course...... but you can't always hover over your kids all day and if a kid is crazier than a cat, they will just find things. Seems the better reaction is to make sure the device works with the bitter coating on the AirTag but someone at Apple said, "no! Can't parents just do their jobs?!? If they eat the battery, then they learned a lesson!" so there you go.
 
Well, yeah, or the kid treats it like an Oreo cookie and opens it to have the battery fall out.
If your kid is small enough to be in the eating everything phase you probably don't want to give him an AirTag or something small like that because they could choke.
 
As a child of the late 70s and 80s i survived such horrors as these, which were far smaller and more edible

 
What an idea. If only kids did exactly what you meant for them to do always.
Or if parents watch the kids a little more. Sure I know kids get in trouble and you can’t watch them 24/7 but there’s always going to be things that are dangerous to small children. Most households have medicines that are deadly the small children but that’s why you keep them away.

I would’ve liked to see a rechargeable AirPod, but even then I think it would still be a choking hazard.
 
I know this is an old thread but I just found this out the hard way. Very annoying little hiccup for an otherwise simple task.

Duracell recommends to manufacturers to put the negative contact further 3.2mm from the edge of the battery (odd wording because they SAY perimeter of the negative terminal but illustrate 3.2mm from the edge of the cell which is the positive terminal).

Apple puts their negative terminal less than that.

Also the negative terminal on a Duracell battery starts about .77mm from the cells edge. Whereas competitor batteries start around .5mm (duracell uses a gasket, panasonic and engerizer use a folded edge) and that gasket takes up a little more room. Very minor difference but it exist. (Duracell on the right).

Even after I cleaned the cell with 99% isopropyl alcohol I'd get inconsistent results. So I did it again and got it to work. Personally I just used a Energizer CR2032 which seemed to work right out of the box.

This is how I spend my Saturdays..... :rolleyes:

Huh! I've never noticed anything that tried to touch the battery near the edge. It's always just a tab with a bump or a spring in the middle. I must not have fancy enough stuff. :) Good to know!
 
I have the same micrometer.
I think that's a Vernier Calliper. Micrometer looks totally different and looks like a C-Clamp with a rotating vernier on its handle. 😁

Just goes to show even as something as simple as a industrial battery design standard can get hosed.
