How to 'Charge' an Airtag: the Complete Battery Replacement and Maintenance Guide
Opening the casing requires no screwdrivers, pry tools, or razor blades. The device relies on a spring-loaded bayonet mount concealed beneath the polished metal cap. Follow these exact coin cell replacement steps to swap the power cell safely:
1. Position the unit: Hold the AirTag with the white plastic base facing down and the shiny stainless steel cover displaying the Apple logo facing directly up toward you.
2. Apply downward pressure: Place your thumbs firmly onto opposite sides of the metal disc. Push down firmly toward the center of the white shell to compress the three internal retention springs.
3. Perform the counterclockwise twist: While maintaining even downward force, rotate the polished cover counterclockwise approximately 30 degrees until it hits its mechanical stop.
4. Remove the cap: Release thumb pressure. The internal springs will push the stainless steel cover upward, allowing you to lift the hatch away and reveal the coin compartment.
5. Extract and seat the new cell: Tip the depleted cell out. Take a fresh CR2032 3-volt lithium coin battery and press it into the circular tray with the positive terminal (the flat side displaying text and the + symbol) facing upward.
6. Listen for verification: Press the battery down lightly into the spring contacts. The AirTag will immediately emit a crisp, musical chime. This AirTag chirp sound confirmation indicates the circuit closed successfully and the firmware initialized.
7. Lock the hatch: Align the three metal tabs on the underside of the stainless cover with the three slots in the plastic housing. Push down firmly and twist clockwise until the cover locks tightly into place, aligning the printed text horizontally.
