The non coated design ensures broad compatibility across different brands and devices without the connectivity issues sometimes caused by bitterant coatings.

I bought these CR2032 3V batteries to feed my very needy Apple AirTags, and so far they are doing their job without drama. I popped them in, the AirTags woke right up, and my phone stopped yelling at me about low battery every five minutes. For something that looks like a shiny little metal coin, they pull their weight. They fit perfectly in the AirTags, no weird sizing issues, no forcing the cover closed, and I like that I can grab a multipack without paying brand name prices. I use AirTags on keys, bags, and the usual “things I misplace at least twice a week,” so having a stash of these on hand is non negotiable. When one AirTag starts whining, I just swap in a new battery and it is back to stalking my stuff like normal. Are they fancy No. Do they need to be, Also no. They last a reasonable amount of time, they do not corrode all over the inside of the device, and they keep my trackers alive so I am not tearing apart the house looking for my keys like a raccoon in a panic. If you use Apple AirTags and do not feel like spending extra just for a logo, these little batteries get the job done. Toss a pack in a drawer, forget about them until your AirTag complains, then enjoy feeling like a responsible adult who actually had backups ready. Read more
