An AirTag is packed with a user-replaceable battery designed to last approximately one year. When the AirTag battery is low, your iPhone will send a notification. You can also check the AirTag's battery life manually. A dead battery will disable your AirTag, but replacing it is a quick and easy process that you can do at home. In this article, we'll walk you through all the steps to securing a new battery in place to get your AirTag back up and running in no time. Let's get started!
The easiest way to replace your AirTag battery in 2024!
Apple's AirTag uses a CR2032 lithium CV coin battery which is widely used in remote controls and practical electronic devices. These batteries are popularly known as button cell batteries or watch batteries. To prevent accidental ingestion by small children, Apple recommends using a CR2032 battery coated with bittering agent. You can also use a Duracell 2032 Lithium Coin battery with Bitter Coating.
Before purchasing a replacement battery, be sure to check its compatibility. Some packages explicitly state that they are "AirTag compatible". If you can't find it, just make sure it's a CR2032 battery with a bitter coating. It is worth mentioning that some CR2032 batteries may not work with AirTags. In such a case, you can scrape off the coating slightly with a sheet of sandpaper.
CR2032 lithium CV coin batteries are available at most electronics and drugstores.
