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
Press down on the polished stainless steel battery cover of your AirTag and rotate counterclockwise until the cover stops rotating.
Remove the cover and battery.
Insert a new CR2032 lithium 3V coin battery (available at most electronic and drug stores) with the positive side facing up. You'll hear a sound indicating that the battery is connected.
Keep batteries away from children. To further discourage accidental ingestion, use a bitterant-coated CR2032 battery, like the Duracell 2032 Lithium Coin Battery with Bitter Coating. Look for packaging that states "Compatible with Apple AirTag". Some CR2032 batteries with bitterant coatings might not work with AirTag or other battery-powered products.
Replace the cover, making sure that the three tabs on the cover align with the three slots on the AirTag.
Rotate the cover clockwise until it stops.
