Your AirTag is designed to run for about a year on a single battery. When that time’s up, you don’t have to buy a new one because replacing the battery is quick, inexpensive, and tool-free.
Here’s how to tell when your AirTag battery is low and exactly how to remove the stainless steel panel to change it.
How to Know When Your AirTag Battery Needs Replacing
You won’t see a percentage indicator like you do for your iPhone or Apple Watch, but Apple will let you know when it’s time to swap the battery.
You’ll get two signs:
- A low battery notification on your iPhone: “AirTag Battery is Low.”
- In the Find My app, your AirTag will show a low battery icon below its name.
There’s no set expiry date, but most AirTag batteries last about 12 months with regular use.
What Battery Do AirTags Use?
AirTags use a CR2032 lithium coin battery, a common and cheap type that you can buy here or alternatively find them at most supermarkets or electronics shops.
✅ Important: Apple recommends using CR2032 batteries without a bitter coating.
Some coin batteries (especially child-safe ones) have a coating that can interfere with the battery connection in AirTags.
How to Change the Battery in Your AirTag
Replacing the battery takes less than a minute.
Step-by-step:
- Flip the AirTag over so the polished metal side (Apple logo facing you) is on top.
- Press down firmly on the edge of the metal cover with your thumbs, one on each side of the Apple logo.
- Rotate the cover counter-clockwise until it stops (about a quarter turn) and let the cover pop up.
4. Remove the cover and take out the old battery.
5. Insert a new CR2032 battery, positive (+) side facing up.
6. You’ll hear a short chime confirming the new battery is connected.
7. Replace the cover, align it with the tabs, then twist clockwise to lock it.
🪛 No tools required. Just your fingers. If you struggle, try placing it in the palm of your hand and applying pressure with two fingers instead of thumbs.
How Often Should You Replace the Battery?
- Typically, once a year.
- Battery life can vary slightly depending on how often your AirTag plays sounds or gets located via Find My.
It’s a good idea to set a calendar reminder for 11 months after installing a new one so you don’t lose track.
Can You Recharge an AirTag Battery?
No. AirTags do not support charging or rechargeable batteries. You’ll need to use and replace a disposable CR2032 battery.
Final Thoughts
Changing your AirTag battery is as simple as twisting the cap, popping in a new cell, and listening for the chime. There’s no need for tools or a trip to the Apple Store.
Just make sure you use a CR2032 battery without a bitter coating, and you’ll be back up and tracking in seconds.
