Apple’s AirTags are currently the best tracking gadgets available. They look surprisingly stylish for such a practical item, and they work flawlessly with the iOS environment, allowing you to keep tabs on the whereabouts of anything from your keys and baggage to your pet and your rucksack.
The only time you should ever have to service your AirTag is to swap out the battery. The included battery has a lifespan of over a year, but will eventually need to be replaced. Here’s a simple guide to swapping out the battery in your AirTag if you find yourself in need of assistance.
Verify that The Battery in Your Air Tag Has to Be Replaced.
You should verify that the AirTag’s battery is indeed low before attempting any adjustments. Apple has programmed the tracker to alert your phone via a notice when the battery needs to be changed, so you should see a reminder on your lock screen to do so.
If that isn’t happening, or if you’re just curious about the health of your battery, try these steps.
Step 1: Launch the Find My app.
Step 2: Choose the Items menu item.
Step 3: Choose the AirTag you want to examine.
Step 4: There, you’ll find a battery icon that represents how much juice is left in your device.

After determining that your AirTag requires a new battery, you can follow these steps to open up the device and swap it out.
Step 1: while still holding down the cover, press firmly on the AirTag’s stainless steel part and spin it counterclockwise. The thumbs of both hands are used to provide pressure and rotate the AirTag, making it the preferred method of operation.
Step 2: remove AirTag’s case. Make sure there is no dirt caught around the edges if this doesn’t come off easily. Pry it off with your fingers or a small tool.
Step 3: swap out the CR2032 lithium 3V coin battery with a new one, making that the negative end is pointing downward. A whistle will sound when the battery is properly installed.
Step 4: Replace the cover, making that the tabs line up with the slots on the AirTag base. Turn the cover clockwise to secure it.
