How to change the AirTags batteryHow long does the AirTag last
Apple's dinky AirTag tracker is now available as a convenient way to keep tabs on your stuff if you're already immersed in the iOS ecosystem. Unlike other Apple products, you don't charge the AirTag. So here's what to do when the AirTag runs out of battery.
Designed to be attached to a key pair or backpack, the AirTag is a rival to Tile's line of trackers and integrates deeply into the iOS ecosystem. This product has been rumored for centuries, so it's good to see Apple finally let it out in the wild. The system works with most of the best iPhones we've tested over the years.
You can buy AirTags as a single unit (£ 29 / $ 29) or a four-pack (£ 99 / $ 99) and there are several accessories available. We've also detailed how to set up an AirTag with your iPhone - so if you've just picked the tracker, that's a good place to start.
How to change the AirTags battery
AirTag uses a standard CR2032 button cell battery, which means it does not need to be recharged. When the battery dies, you just need to replace it with another one. These particular batteries are very common in supermarkets and other stores and on Amazon they are available in a 10 pack for around £ 5 / $ 5.
It is easy to change the battery. Just flip the AirTag on its stainless steel side, push it down and turn it. The back should come out and you can then remove the cell. Insert a new one and reinstall the back panel.
How long does the AirTag last
Apple says the button cell battery inside an AirTag should last a year before needing to be replaced. This is ideal because it's not something you really want to worry about running out of charge in a matter of days or weeks.
You will receive an alert on your iPhone when an AirTag needs to change its battery so that it doesn't randomly run out of power without you realizing it.
