5 Tips to Replace AirTag Battery

AirTag is a small item finder for Apple devices. A dead battery means that AirTag can’t communicate with Find My Network and thus can’t track your items.

The AirTag battery replacement process is quick and easy. All you need is a few minutes and a new CR2032 coin cell battery. This guide will walk you through each step to ensure the AirTag is back up and running.

If you don’t want to use a battery-operated tracker, you can choose the Seinxon tracker and use the rechargeable model.

Signs that the Battery is Low or Dead

Your AirTag will notify you when the battery is low through your connected Apple device. You might also notice the AirTag not responding or not appearing in the Find My app, indicating the battery is dead.

Open the Find My app on your iPhone or iPad. Select the AirTag you want to check. If the battery is low, you will see a low battery notification below the AirTag’s name. This notification indicates it’s time to replace the battery.

Preparing for Battery Replacement

You don’t need any special tools to replace the AirTag battery. All you need is a new CR2032 coin cell battery, which you can find at most electronics stores or online.

Ensure you purchase a CR2032 coin cell battery, as this is the type compatible with AirTags. Avoid using used or off-brand batteries to ensure optimal performance.

Step-by-Step Airtag Battery Replacement Guide

Removing the AirTag from Its Accessory 

First, remove the AirTag from any keychain or accessory it might be attached to. This makes it easier to handle during the battery replacement process.

Opening the AirTag to Access the Battery

Hold the AirTag with the white side facing down. Press down on the stainless steel back cover and rotate it counterclockwise. The back cover will pop off, revealing the battery inside.

Removing the Old Battery

Carefully lift the old battery out of the AirTag. Dispose of it properly, following local regulations for battery disposal.

Inserting the New Battery

Take the new CR2032 coin cell battery and insert it into the AirTag with the positive side (marked with a +) facing up. Ensure it is seated properly in the compartment.

Securing the AirTag and Testing the New Battery

 Place the back cover back onto the AirTag. Press down and rotate it clockwise until it locks into place. Once secured, the AirTag will emit a sound to indicate it has powered on. Open the Find My app to confirm the AirTag is working correctly with the new battery installed.

By following these steps, you can easily replace the battery in your AirTag, ensuring it continues to function effectively for tracking your valuable items. Regular maintenance and timely battery replacements will keep your AirTag performing at its best.

Troubleshooting Common Issues

If your AirTag doesn’t power on after replacing the battery, check to ensure the battery is seated correctly and the positive side is facing up. Try using a different CR2032 battery to rule out a faulty battery.

Make sure the battery is properly aligned and fully inserted into the compartment. If the battery is not seated correctly, the AirTag may not function.

Ensure you are using a compatible CR2032 battery. Some off-brand batteries may not fit correctly or provide the necessary power. Use a reputable brand to avoid issues.

What is the Lifespan of the AirTag Battery?

The AirTag battery typically lasts up to one year. Within minutes, you can identify where your AirTag is remotely, even if it’s on the other side of the world, saving you days or even weeks of stress and anxiety. 

However, AirTags only function effectively if they have sufficient battery power. It’s crucial to be aware of the battery’s lifespan to ensure continuous tracking capabilities. I recently learned this firsthand while traveling in Europe when my AirTag’s battery needed replacement after about a year of use.

Maintaining Your AirTag

To prolong the battery life of your AirTag, avoid exposing it to extreme temperatures. Regularly check the battery status in the Find My app and replace the battery promptly when it is low.

Periodically inspect your AirTag for any signs of damage or wear. Ensure the back cover is securely fastened and the AirTag is clean and free from debris.

Clean your AirTag with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Keep the AirTag in a secure accessory to prevent it from being damaged or lost.


Replacing the battery in your AirTag is a simple and straightforward process that ensures your device remains functional and reliable. By following the steps outlined in this guide, you can easily replace the battery and keep your AirTag working efficiently.
