Earlier quoted context omitted.
Given that the battery in my Airtag lasts about a year, I'd rather have to exchange a CR2032 once per year than to buy a new tracker whenever the built-in rechargeable battery inevitably dies. (I think there are actually rechargeable CR2032s too – best of both worlds?)
There are, and I got cursed with a BMW that uses one of them. Eventually after 10+ years it finally dies, and it's basically impossible to replace and actually make it work again, so I just have to replace the 2032 in it every few months.
Since the islands he now lives on has no BMW presence they want him to ship the car back to get new keys.
