Apple AirTag Battery

Introduction

Apple’s AirTag has quickly become a favorite tool for many to keep track of their belongings. With its sleek design and seamless integration with the Apple ecosystem, it promises convenience like never before. Because people are using AirTags to track their important belongings they obviously want to know how long do AirTag batteries last. In this guide we will discuss battery life, step by step instructions on how to change the battery, and how you can monitor how much power is remaining.
 
Some of the most commonly asked questions are with regard to the battery. Is it rechargeable? How long does it last? And if needed, how do you replace it?
 

Is the battery in the Apple AirTag rechargeable?

Unfortunately, the battery in the AirTag is not rechargeable.  However, it is powered by a replaceable CR2032 battery that lasts up to a year!  The CR2032 is a common battery you can buy at most convenience or grocery stores and is commonly known as a “watch battery.”
 

How do I replace the battery in an AirTag?

Your iPhone will notify you when your AirTag battery is running low and it is time for a replacement.
 
To replace the battery:
  • Remove the AirTag from any holder it might be in (i.e. key chain, luggage tag, pet collar, etc.)
  • Hold it in your hand with the stainless steel side facing up
  • Using your thumbs press down and rotate the cover counterclockwise until the cover releases
  • Remove the cover and the battery
  • Replace the battery with the positive side (+ symbol) facing up
  • To replace the cover align the three tabs on the cover with the three slots on the back of the airtag
  • Press down and rotate the cover clockwise until secure
  • Once the cover is replaced the AirTag will make a chime sound. The chime indicates that the battery is connected, but you will still want to make sure the cover is completely closed to avoid damage.

How can I check the battery level on an AirTag?

People often wonder how to keep track of the amount of battery power remaining in their AirTag. To check the battery level of your AirTag open the “Find My” app on your iPhone.
 
You can do this by swiping down on the Home Screen and typing Find My in the search box or by going flipping through the applications on your Home Screen until you find it.  Once it has opened you will see all the devices associated with your Apple ID account.  At the bottom of the screen select the items tab and scroll down to your AirTag name and select it.
 
On that screen you will see a battery icon with an approximate charge indicated by how full the battery icon looks.  If the charge level is red that indicates it is time to change the battery.
 
Also, remember that your phone will notify you when the battery in your AirTag us running low and it’s time to replace it.
 

Frequently Asked Questions (FAQ)

Can an AirTag connect to multiple phones?

Currently, your AirTag can only be associated with one Apple ID. If both devices use the same Apple ID then you will be able to see the AirTag on both devices in the Find My app.

However, beginning with the release of IOS 17 in September 2023 you will be able to share your AirTag locations with friends and family.

Are AirTags waterproof?

AirTags are not waterproof but they are water resistant and have a IP67 rating (i.e. water, splash, and dust resistant). They can be submerged for 30 minutes in 3 feet of water without any damage. So they will be fine if you use them in the rain or accidentally mix them in with the laundry but can be damaged with longer exposure to liquids. There are waterproof cases you can purchase that will effectively make your AirTag waterproof.

How much does a CR2032 battery cost?

CR2032 batteries can be found at most convenience and grocery stores or on Amazon.com and cost $5-$10 for a six pack depending on the brand you choose.  CR2032 batteries have a long shelf life, so you can stock up without fear of them losing their charge.
 

Conclusion

Too quickly summarize, your AirTag is not rechargeable but does use a CR2032 battery that can last approximately one year.  Your iPhone will notify you when it is time to change the battery, but if you want to check the battery level intermittently you can do so using the “Find My” application on your iPhone.
 
Also, remember that beginning with the release of IOS 17 in September 2023 you will be able to share your AirTag locations with friends and family. This will be helpful to people who share specific items using AirTags such as keys.
