How To Replace Airtag Battery 2024 Guide

What Batteries Does an AirTag Use?

Apple’s AirTag uses a CR2032 lithium CV coin battery that’s commonly used in remote controls and handy electronic devices. These batteries are popularly known as coin cell batteries or watch batteries. To discourage accidental ingestion among small children, Apple recommends using a bitterant-coated CR2032 battery. You can also use a Duracell 2032 Lithium Coin Battery with Bitter Coating.
Before you buy a battery replacement, make sure to check its compatibility. Some packages explicitly state that they are “Compatible with AirTag”. If you don’t find that, just make sure it’s a CR2032 battery with a bitterant-coating. It’s worth mentioning that some CR2032 batteries may not work with AirTags. In such a case, you can slightly scratch off the coating with a sandpaper sheet.
CR2032 lithium CV coin batteries are available at most electronic and drug stores.
