Apple AirTags have become a go-to solution for keeping track of everyday items like keys, wallets, or even pets.

These tiny trackers rely on a replaceable battery to stay powered and functional. When your AirTag’s battery runs low, there’s no need to panic or replace the entire device—swapping out the battery is quick, affordable, and something you can do at home.

In this guide, we’ll walk you through the process of replacing your AirTag battery with clear instructions, helpful tips, and resources to ensure your tracker keeps working like new.

Step-by-Step Guide to Replacing the Battery

Follow these simple steps to swap out your AirTag’s battery in just a couple of minutes.

Step 1: Check the Battery Status

First, confirm the battery needs replacing. Open the Find My app on your iPhone:

  • Tap the Items tab.
  • Select your AirTag from the list.
  • Look for a “Low Battery” warning beneath its name.

If you see this alert, it’s time to proceed. No warning? Your AirTag might still have some juice left, but replacing the battery proactively can prevent unexpected shutdowns.

Step 2: Open the AirTag

Hold your AirTag with the shiny stainless steel side (the battery cover) facing up. This is the side with the Apple logo.

  • Press down firmly on the cover with your thumbs. You’ll feel a slight give.
  • While pressing, rotate the cover counterclockwise. It won’t spin far—about a quarter turn—until it stops.
  • Lift the cover off gently. If it’s stubborn, try pressing harder or using a soft cloth for extra grip.

The design is child-resistant, so it might take a couple of tries to get the motion right.

Step 3: Remove the Old Battery

Once the cover is off, you’ll see the CR2032 battery nestled inside. Carefully pop it out with your fingers or tap the AirTag lightly on your palm to dislodge it. Set the old battery aside for proper recycling—don’t toss it in the trash, as lithium batteries require special disposal. Check your local recycling center or use Apple’s recycling program for guidance.

Step 4: Insert the New Battery

Take your new CR2032 battery and place it into the slot, positive side (+) facing up. The positive side is the flat, shiny surface, often marked with a “+” symbol.

  • Press it down gently until it sits flush.
  • You’ll hear a faint chime from the AirTag—this means the battery is connected and recognized.

No chime? Double-check the battery orientation or try a different CR2032, as some may be duds or incompatible.

Step 5: Reattach the Cover

Place the stainless steel cover back onto the AirTag, aligning its three tabs with the three slots on the device.

  • Press down lightly and rotate clockwise until it locks into place. You’ll feel it stop when it’s secure.
  • Give it a gentle tug to ensure it’s snug.

Step 6: Test Your AirTag

Head back to the Find My app:

  • Select your AirTag.
  • Tap Play Sound to confirm it’s working.
  • Check that the low-battery warning is gone.

If everything checks out, your AirTag is ready to roll with a fresh power supply.

Where to Buy Replacement Batteries

CR2032 batteries are widely available. Grab them from:

  • Electronics Stores : Best Buy or RadioShack.
  • Online Retailers : Amazon’s CR2032 selection offers bulk packs for multiple AirTags.
  • Pharmacies : CVS or Walgreens often stock them near the checkout.

Opt for trusted brands like Energizer or Panasonic for reliable performance.

Final Thoughts
