How to change the AirTag battery quickly and easily

Apple’s AirTag is handy Bluetooth accesory that gives you an idea of where all your tech is. If you’ve picked up an AirTag since its launch you’re probably going to need to change the battery – here’s how to do it.

The AirTag is an interesting device because, unlike just about every other Apple product, it can’t be charged up via a Lightning or USB-C cable. Instead, when the AirTag runs out of juice you’ll need to physically change the battery inside to get you back up to 100%.

The Find My app will let you know when your AirTag needs a new cell and the battery itself is a widely used CR2032 coin cell unit. You can pick these up from a supermarket, electrical store, pharmacy or online. See below for the specific unit we used.

The AirTag system works with many of the best iPhones we’ve tested.
