April 6, 2025

Check If Your AirTag Battery is Low

Before replacing, check if the battery is low. The iPhone gives a notification when the battery is almost dead. You can also manually check it using Find My. Open the Find My app on your iPhone.

Tap on Items to see all connected devices. Choose your AirTag to check its battery level. If it shows “Low Battery”, replacement is needed. Never wait too long after seeing the notification. A dead battery makes AirTag completely useless.

The AirTag battery usually lasts for one year. Still, it’s good to check every few months. This helps you avoid problems in urgent situations. Regular checking ensures your AirTag always stays active.

Which Battery to Use for AirTag in 2025

AirTag uses CR2032 lithium coin cell batteries only. These are easily available in local electronics stores. You can also find them in big medical shops. Apple suggests using bitterant-coated CR2032 batteries. This coating keeps small children from eating them. Duracell 2032 with Bitter Coating is a good option.

Before buying, check the label on the battery pack. Look for “Compatible with Apple AirTag” on it. Some coated batteries might not work properly inside AirTag. In such cases, gently scratch the coating using sandpaper. Be careful while doing this, avoid damaging the battery.

Do not use any other battery model or type. Only CR2032 batteries work well with Apple AirTag. Other batteries may not fit or cause damage. So always double-check before making any purchase online.

Warning: Always keep small batteries away from children. Both battery and cover can cause choking hazard. Never allow kids near you during the replacement process.

Extra Tips to Keep Your AirTag Working Well

If your AirTag is not pairing with the iPhone, Try removing and reinserting the same battery again. This small step sometimes solves pairing or connection issues. If the problem continues, then change to a new battery.

Also, check if the battery is placed correctly inside. Wrong placement can stop your AirTag from working. You should always hear a beep after insertion. No sound means the battery is not working right.

Always close the back cover tightly after changing. Loose covers may cause poor contact with the battery. This can stop AirTag from sending proper signals.

Try to replace the battery once every year. Even if it seems fine, don’t take risks. AirTag is a useful tracker and needs good power. Timely battery changes keep it running without problems.

Store extra batteries in a safe and dry place. Avoid moisture or heat which can damage the battery.

The Final Words

You now know how to replace the AirTag battery in 2025. It’s a simple task that takes a few minutes. Use only CR2032 batteries and follow the steps carefully.

Always check your AirTag battery through your iPhone. With proper care, your AirTag will last long. Keep it charged, stay safe, and track your things easily.
