Can you replace an AirTag battery?
Best answer: Yes, you can absolutely replace an AirTag battery, and you can do it yourself for a low cost.
What is AirTag?
Apple's AirTag is a small, disk-shaped tracking device that can be slipped inside or attached to your valuables via AirTag accessories. Using the Find My app, you can track down the AirTag and whatever item you've attached it to. The AirTag's battery is easily replaceable. Best of all, you don't have to take it to your local Apple Store to replace it. You can easily do it at home without any tools. The replacement battery costs only a few bucks and can be found in just about any store that carries batteries.
What kind of battery does AirTag use?
The AirTag uses a CR2032 battery. This is not a special proprietary battery; it's an ordinary 3-Volt lithium coin cell battery that you can buy at any drugstore. You'd commonly find this inexpensive battery powering wristwatches, car key fobs, calculators, and other small electronics.
- Note: When buying a CR2032 battery, be sure to buy one without the bitterant coating that some battery makers use to discourage children from swallowing them. I found out the hard way that the AirTag won't work with a coated battery.
How long does an AirTag battery last?
The battery the device comes with should last about a year with normal use.
How will you know when it's time to replace the AirTag's battery?
There's no need to guess. Your iPhone will let you know when your battery is low, in plenty of time for you to purchase a replacement.
Can you replace the AirTag battery yourself?
Yes, you can. No special tools or skills are required. Simply press and twist the metal front of the AirTag counterclockwise while keeping the plastic back stationary and then lift. It's a similar motion to opening a child-proof cap on a medication bottle. The battery is housed between the two pieces, simply remove it and replace it with a fresh one.

The AirTag runs on an ordinary user-replaceable CR2032 battery.
