I got this brand just few weeks ago ... 20ct for $3.58.
Dont know about quality of these because I haven't used them yet.. but cheap, might just have to replace more often?

Quote from adtruck :

Key DifferencesDimensions: CR2032 measures 20 mm × 3.2 mm; CR2450 measures 24 mm × 5.0 mm.Capacity: CR2032 holds ~225 mAh; CR2450 holds ~620 mAh (lasts nearly 3 times longer under similar loads).Anyone tried these in an AirTag?

Worked for me. Thanks.

This is not for AirTag. AirTag uses CR2032. CR2450 is both thicker and wider. I have insignia garage door HomeKit sensor that uses this 2450 battery. Should be good supply for a few years.

Also a trick: my car key fob uses CR2354 which is very close to 2450 in terms of thickness but slightly smaller. So what I did before was to buy a bunch of 2354 on discount and used them in my 2450 sensor too -- I added a tiny rubber filling in the battery compartment so it fits nicely. This way I don't have to buy two kinds of batteries. But this deal makes it easier

Some vehicle keyfobs use these chunkier 2450 batteries. Toyota's recent ones definitely do... but yeah airtags definitely use the smaller 2032 coin cells.
