Duracell 2023 Batteries Don't work with Apple AirTags
Found I couldn't use the most respected Duracell batteries in my AirTag. Eventually figured these coin-cell batteries are coated with a bitter taste so children will spit the battery out if they try to swallow it.
Solution is to wash the bitter taste coating off as it clearly insulates the battery. I use water and a kitchen sponge abrasive, which works in seconds. Suggest you wash your hands in case the bitter taste compound gets on your fingers.
Duracell do not provide any advice that the batteries must have the bitter taste compound removed in order to use their batteries. How stupid is that. Maybe they think 2 year olds could read this :-(
