While it may be some time before consumers are required to replace the button cell battery in their AirTag, Apple has issued a warning that bitterant coatings may cause the gadget to malfunction.
Users should avoid buying batteries with bitterant coatings, according to an Apple support document about AirTag battery replacement.
CR2032 batteries with bitterant coatings might not work with AirTag or other battery-powered products.
Some battery manufacturers apply a particular coating to prevent toddlers from eating small power sources. Bitterants are non-toxic compounds that have a bitter odor or taste and are widely employed to prevent people from ingesting or inhaling potentially harmful substances. Chemicals used by battery manufacturers react with saliva to produce a foul odor.
Apple launched the help website just days after Australia issued a consumer alert advising parents to keep AirTag out of the reach of children due to the device’s easily accessible battery, which can cause choking.
