What you need to know
- Apple has warned AirTag users not to use batteries that are coated in bitterant used by some manufacturers.
- The company says this could prevent your AirTag from working properly.
- Bitterant is used by companies like Duracell to discourage young children from swallowing them.
A coating used by battery companies to stop young children from swallowing lithium coin batteries could cause Apple's AirTags to stop working, the company has warned.
The document is titled How to replace the battery in your AirTag and details the steps users must follow to replace the battery inside its new tracking device, steps that can also be found in our 'How to replace an AirTag battery' guide. AirTags use standard CR2032 batteries that you can buy basically anywhere, but the company says that certain batteries that use a bitterant coating might not work:
According to Duracell every year hundreds of lithium coin batteries are ingested by young children because of their small size. The company last year started applying Bitrex to its batteries to prevent this:
The company does this because a swallowed battery can become a potentially fatal problem for young children, causing a harmful chemical reaction if it gets stuck in the esophagus. A neat safety measure, this does however mean these batteries aren't suitable for use with AirTags, so make sure you check before buying!
You can do it
The AirTag runs on an ordinary user-replaceable CR2032 battery.
