Your AirTag battery only lasts a year — here's how to check it

Editor's Note

This is a recurring post, regularly updated with new information and offers.

If you've only recently started using an AirTag to track your luggage, you may not realize that the original AirTag battery only lasts for roughly one year. Just as you can replace your iPhone battery, you can also replace your AirTag battery when it runs out of power.

Now that you can share your AirTag information directly with several airlines to help locate your lost luggage more quickly, it's more important than ever to ensure your AirTag's battery health is strong.

When your battery is on the brink of death, Apple will notify you via the FindMy app if you've connected your AirTag within the app. You can also proactively check the battery level within the app by opening it and identifying your AirTag under the "Items" tab at the bottom. Consider it one more task for your pretravel "to-do" list.

Instead of replacing the AirTag itself when the time comes, you can replace the battery for a lower cost. Then, you can continue using the AirTag as normal. According to Apple, you should use a CR2032 lithium 3-volt coin battery that states "Compatible with Apple AirTag."

Compatible batteries include the Panasonic CR2032 and Energizer CR2032 batteries, both of which are currently available on Amazon. You can also find compatible batteries at most electronics stores and drugstores, per Apple.

Bottom line

If you've had your AirTag for anywhere close to a year, we recommend you go ahead and buy a pack of batteries so you have them on hand when the time comes.

If you can't find a battery in time or prefer to replace your AirTag entirely, the regular price for a single tag is $29. Alternatively, you can purchase a four-pack for $99, although we often see AirTags on sale through Amazon.

Why We Chose It

There’s a lot to love about the Amex Gold. It’s a fan favorite thanks to its fantastic bonus-earning rates at restaurants worldwide and at U.S. supermarkets. If you’re hitting the skies soon, you’ll also earn bonus Membership Rewards points on travel. Paired with up to $120 in Uber Cash annually (for U.S. Uber rides or Uber Eats orders, card must be added to Uber app and you can redeem with any Amex card), up to $120 in annual dining statement credits to be used with eligible partners, an up to $84 Dunkin’ credit each year at U.S. Dunkin Donuts and an up to $100 Resy credit annually, there’s no reason that foodies shouldn’t add the Amex Gold to their wallet. These benefits alone are worth more than $400, which offsets the $325 annual fee on the Amex Gold card. Enrollment is required for select benefits. (Partner offer)
