Battery Specifications & Life
- Battery Type: CR2032 3V Lithium Coin Cell.
- Expected Lifespan: 12 to 14 months under normal use.
- Low Battery Alert: Your iPhone automatically sends a notification when battery capacity reaches ~15%.
How to Replace in 30 Seconds:
- Press down on the polished stainless steel battery cover.
- Rotate counterclockwise to unlock and remove the cover.
- Replace with a fresh CR2032 battery (positive + side facing up).
- Re-attach cover and rotate clockwise until it clicks.
⚠️ Warning: Avoid CR2032 batteries with bitter child-safety coatings (like Duracell Bitter Coating), as the coating can prevent electronic contact with AirTag terminals. Use standard uncoated CR2032 batteries (Energizer, Panasonic, Sony).
