It is possible that the battery you installed is not properly seated or is not compatible with the AirTag. If the battery is not seated properly, it may not make contact with the device and will not power it. Additionally, using a battery that is not compatible with the AirTag can cause issues such as this one.
Here are a few steps you can try to fix the issue:
- Make sure that the battery you installed is the correct type for the AirTag. The AirTag uses a CR2032 lithium coin cell battery.
- Carefully inspect the battery compartment of the AirTag to ensure that the battery is seated properly. Make sure that the positive (+) and negative (-) terminals of the battery are aligned with the corresponding terminals in the battery compartment.
- If the battery is seated properly and you are using a CR2032 battery, try removing and reinserting the battery. This can sometimes fix issues with the battery not making contact with the device.
- If the issue persists, try resetting the AirTag. To reset the AirTag, press and hold the button on the device for 10 seconds. This will erase all data from the device and restore it to its factory default settings.
