AirTags are small tracking devices designed by Apple that help many people keep track of their belongings through the Find My network. However, some users who replace their AirTag’s battery may encounter an unusual issue. After replacing the old battery with a new one, the AirTag might stop working. This is especially confusing when the AirTag functions properly if you swap the old battery back in. So what’s going on?
This issue occurs due to the AirTag’s design and the specifications of its battery. AirTags are powered by a CR2032 lithium coin battery, and it’s crucial to use the correct type. Not all CR2032 batteries will be compatible due to variations in design or additional coatings that some brands apply.If your AirTag stops working with a new battery but works correctly with the old one, it often signifies that the new battery isn’t meeting the necessary requirements. Users must ensure that the new battery’s positive side is up and that there is no bitterant coating, which may prevent proper contact. Additionally, cleaning the AirTag’s battery contacts can help resolve connection issues with the new battery.
Help! My AirTag Won’t Work After Changing the Battery
It can be frustrating when your AirTag suddenly stops working after a battery replacement. Here’s why this might happen and how to fix it:
The Culprit: Battery Coatings
- Bitterant Coatings: Some battery brands, Duracell in particular, add a bitter, non-toxic coating to deter children from swallowing them. Unfortunately, this coating can interfere with the electrical connection inside your AirTag.
- Solution: Remove the coating using an alcohol wipe or gently scrape it off with a fingernail or a flat object.
Other Potential Reasons
- Incorrect Battery Placement: Ensure the battery is inserted correctly with the positive (+) side facing up.
- Dirty Contacts: Clean the battery contacts on your AirTag with a cotton swab dipped in a small amount of rubbing alcohol.
- Defective Battery: While rare, a new battery could be faulty. Try a different one.
- AirTag Reset Needed: Try resetting your AirTag by removing and replacing the battery five times.
Table: Troubleshooting Tips
| Issue | Solution |
|---|---|
| Bitterant Coating | Wipe the battery with alcohol or gently scrape off the coating |
| Incorrect Installation | Make sure the positive (+) side of the battery faces up |
| Dirty contacts | Clean the AirTag’s battery contacts with alcohol |
| Faulty battery | Try a different battery |
| Resetting needed | Reset your AirTag by removing and replacing the battery five times in a row |
Important Note: Use only CR2032 batteries with your AirTag.
Key Takeaways
- AirTags require CR2032 coin batteries without bitterant coatings.
- Battery contact issues can prevent AirTags from recognizing a new battery.
- Proper placement of the new battery is crucial for AirTag functionality.
Troubleshooting AirTag Battery Issues
When an AirTag works with an old battery but not a new one, it’s key to identify possible causes, ensure correct replacement, and understand factors affecting performance.
Identifying Common Problems
If an AirTag shows a low battery notification but fails to work with a new CR2032 battery, first confirm the battery indicator in the Find My app on an iPhone. Sometimes, the issue is not the battery itself but the connection or battery contacts.
Replacing the Battery
To replace an AirTag’s battery, follow these steps. First, remove the stainless steel battery cover by pressing down and rotating it counterclockwise. Ensure the new CR2032 lithium 3V coin battery is placed with the positive side facing up. After, line up the three slots on the AirTag with the three tabs on the cover and rotate clockwise to secure it.
Factors Affecting Battery Performance
Factors that affect battery performance include the brand of the CR2032 and whether it has a bitterant coating. Some users report issues with bitterant-coated CR2032 batteries. Brands like Panasonic or Duracell without bitter coatings, available on Amazon, are advisable. Always check for compatibility.
Safety and Handling
Small children can risk harm from batteries, treated with bitterant or not. A bitterant is meant to deter ingestion, but it’s still a choking hazard. The Duracell 2032 lithium coin battery with bitter coating serves this safety purpose. Always keep batteries away from kids.
Technical Support and Warranty
For unresolved issues after trying the above tips, reach out to Apple Support. If your AirTag still doesn’t work, it may be covered under warranty. Apple may offer a replacement. Always check the published date for warranty and support information.
