To replace the battery in an AirTag, follow these steps:
1. **Prepare a Replacement Battery**: Ensure you have a suitable replacement battery for your AirTag. AirTags use a CR2032 coin cell battery.
2. **Locate the Notch**: Turn the AirTag over so that the white side is facing up. Look for a small notch or groove along the edge of the white side.
3. **Press In and Twist**: Using your thumb or a small tool, such as a coin or flathead screwdriver, press into the notch and twist counterclockwise. Apply gentle pressure until the cover pops open.
4. **Remove the Old Battery**: Once the cover is removed, carefully lift out the old battery from the battery compartment. Be cautious not to damage the AirTag or the compartment.
5. **Insert the New Battery**: Take the new CR2032 coin cell battery and place it into the battery compartment with the positive (+) side facing up. Ensure the battery sits flat and is properly aligned.
6. **Replace the Cover**: Align the cover with the battery compartment and gently press down until it clicks into place. Ensure the cover is securely fastened to prevent water or dust from entering the AirTag.
7. **Test the AirTag**: Once the battery is replaced and the cover is securely attached, test the AirTag to ensure it powers on properly. You can do this by placing the AirTag near your iPhone or iPad and checking if it appears in the Find My app.
8. **Dispose of the Old Battery**: Safely dispose of the old battery according to local regulations for recycling electronic waste. CR2032 batteries should not be thrown away with regular household trash.
It's essential to use caution when handling the battery and ensure it is inserted correctly to avoid damaging the AirTag or causing injury. If you encounter any difficulties or are unsure about replacing the battery yourself, consider seeking assistance from an authorized Apple service provider. Additionally, refer to Apple's official support documentation for detailed instructions specific to your AirTag model.
