How to replace the battery in your AirTag

You can replace the battery in your AirTag. Here’s how. 

Warning: AirTag, the battery cover and the battery might present a choking hazard or cause other injury to small children. Keep these items away from small children.


Replace your AirTag battery

  1. Press down on the polished stainless steel battery cover of your AirTag and rotate anticlockwise until the cover stops rotating.
  2. Remove the cover and battery.
  3. Insert a new CR2032 lithium 3V coin battery (available at most electronic stores and pharmacies) with the positive side facing up. You’ll hear a sound indicating that the battery is connected.
    CR2032 batteries with bitterant coatings might not work with AirTag or other battery-powered products, depending on the alignment of the coating in relation to the battery contacts.
  4. Replace the cover, making sure that the three tabs on the cover align with the three slots on the AirTag.
  5. Rotate the cover clockwise until it stops.
