The AirTag is said to provide over a year of battery life in everyday use. But that doesn’t mean Apple doesn’t offer the option to keep tabs on AirTag battery life. When your AirTag’s battery is low, your Apple device will alert you with a notification so you can schedule a replacement. Additionally, there is an easy way to replace the AirTag’s existing battery. Apple’s AirTag features a CR2032 battery, which is user-replaceable and widely available through online or offline stores near you.

But before buying a new battery for your AirTag, you should check the condition of your existing battery, as the company claims to last a year with a decent amount of usage.

How to Check AirTag Battery Life

Before starting the steps to check AirTag battery life, it is important to note that the device must be connected to the Find My application. Your Apple device (which can be an iPhone, iPad or Mac) should also be connected to a Wi-Fi or cellular network to provide accurate details. If these two conditions are met, you can proceed with the following steps.

  1. Open the Find My app on your Apple device.

  2. Now, click on the name of your AirTag. You’ll see the battery status right the AirTag’s name and location.

Apple does not provide an option to view the exact percentage of battery remaining on the AirTag. However, the battery status provided through the Find My app is enough to you when it’s time to replace it.

How to Replace the AirTag’s Battery

You can replace your AirTag’s battery in just a few steps. Before starting the replacement process, make sure you have removed the AirTag from its attached accessory or case.

  1. Hold the AirTag with the stainless steel battery cover facing you.
  2. Press the cap down and turn it counterclockwise until it stops.
  3. Let go of your fingers. The battery cover will now pop off.
  4. Pull the cover and remove the battery, then insert a new battery with the positive side of the battery facing you.
  5. Once the battery is properly seated, align the three tabs on the cover with the available slots on the AirTag and press down with a little pressure to replace the cover.
  6. The AirTag will now play a song to indicate that a new battery is attached.
  7. Turn the cap clockwise until it stops.
