TIL Duracell's CR2032 batteries don't immediatley work with AirTags - lemm.ee

Thought I had gotten a bad batch of batteries because no matter what I did, I couldn’t get an AirTag back online after a replacement. Turns out, the bitter coating seems to be preventing proper contact in the AirTag. Cleaning the battery off with an alcohol swab solved the problem immediately for me and my AirTag came right back online.
