If your AirTag still shows a low battery after replacing it, there are several steps you can take to troubleshoot the issue:
1. Verify Battery Installation
- Check Orientation: Ensure that the new CR2032 battery is installed with the positive side facing up. A misalignment can prevent proper contact[1][2].- Secure the Cover: Make sure the metal battery cover is securely fastened. It should rotate clockwise until it stops[1][5].
2. Wait for Updates
- Delay in App Update: Sometimes, there can be a delay in the Find My app updating the battery status. Wait a few minutes and check again[1].3. Remove Residual Charge
- Leave Battery Out: Try removing the battery and leaving it out of the AirTag for 5 to 10 minutes. This can help reset any residual charge that might be affecting the battery reading[3].4. Check Battery Quality
- Bitterant Coating: If you used a battery with a bitterant coating (common in some brands like Duracell), it may not make proper contact. Consider using a different brand or removing the coating with isopropyl alcohol or vinegar[3][7]. Energizer batteries are often recommended as they typically do not have this coating[2].5. Reconnect the AirTag
- Remove and Reactivate: If the above steps do not work, try removing the AirTag from your Apple ID in the Find My app and then re-adding it. To do this, swipe left on the AirTag in the app and select "Remove," then follow prompts to reconnect it[4].6. Test with Another Battery
- Try a Different Battery: If all else fails, test with another new CR2032 battery, as sometimes batteries can be defective or dead upon purchase[3].By following these steps, you should be able to resolve issues with your AirTag showing a low battery even after replacement.
