How to Check an AirTag’s Battery Life and Replace Existing Battery

AirTag is claimed to deliver over a year's worth of battery life with everyday use. But that doesn't mean that Apple has not provided an option to keep an eye on your AirTag's battery life. Your Apple device will alert you with a notification when your AirTag's battery becomes low to let you arrange for its replacement. Additionally, there is an easy way to replace the existing battery of your AirTag. Apple's AirTag carries a CR2032 battery that's 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 status of the existing one as the company claims to offer a fair amount of usage that should last you a year.

Apple doesn't provide the option to look at the exact percentage of battery remaining on your AirTag. However, the battery status available through the Find My app is good enough to suggest when you will need its replacement.

How to replace AirTag's battery

You can replace the battery of your AirTag in just a few steps. Before beginning with the replacement process, make sure you've removed the AirTag from the accessory or case it is attached to. 

1. Hold the AirTag with its stainless steel battery cover facing towards you.
2. Press down the cover and rotate it counter-clockwise until it stops rotating.
3. Release your fingers. The battery cover will now pop up.
4. Pull the cover and remove the battery, and then insert a new one with the positive side of the battery facing towards you.
5. Once the battery is placed correctly, reattach the cover by lining up the three tabs on the cover with the slots available on your AirTag and press it down with a little pressure.
6. The AirTag will now play a song to indicate the new battery is connected.
7. Rotate the cover clockwise until it stops.

Keep the original battery away from children and dispose it off properly.
