Here’s Why Your AirTag Battery Replacement Is Not Working

Very timely! One of the three AirTags I bought when they were initially released just notified me of its low battery. Looking in a drawer, I found a four-pack of CR2032s that I had no memory of purchasing, but were from The Findables Company, which apparently makes a competing product. After I replaced the battery, the AT still said the battery was low. One of Apple’s help pages mentioned the coating, and the “orientation” comment made me repeat the process, this time kind of grinding the battery against the contact inside the AT to see if that would help cut through any coating, and in fact the AT started reporting a full battery.

After reading this article, I’m starting to think that was just a coincidence, as these were certainly not Duracell brand batteries. But it did make me wonder…if the coating keeps the Duracell batteries from working, why would anyone buy them?
