Air Tag Battery: Everything You Need to Know
The air tag battery is small but powerful. It is designed for convenience and long life, especially for travelers.
What Type of Battery Does an AirTag Use?

How Long Does an AirTag Battery Last?
On average, an AirTag battery lasts about one year.
However, battery life depends on:
How often you use Precision Finding

Travel Tip:
Before a long international trip, check your AirTag battery level. Replacing it before departure can prevent tracking issues abroad.

Replace the cover and rotate clockwise until it locks.
You will hear a sound when the battery is correctly installed.

Not all CR2032 batteries are the same.
When traveling, choose:
Trusted brands (Energizer, Duracell, Panasonic)

Important:
Some CR2032 batteries with bitter coatings may not make proper contact inside the AirTag. Always test the battery after installation.
