If you’re an Apple user and want to keep track of all your stuff, owning an AirTag is a must. But what makes them phenomenal is their long-lasting battery life.

If you’re new to AirTags, or perhaps considering buying some, one question you might be curious about is, do AirTags have lithium batteries? Fear not, because I have the answer in this article.

AirTags come with a Panasonic CR2032 3V lithium coin cell battery out of the box. The CR2032 lithium-ion battery is the go-to choice when powering small electronic devices such as car key FOBs, calculators, watches, fitness trackers and medical devices.

In this article, I explore topics like does an AirTag have a lithium battery, whether you can charge an AirTag battery, and much more.

Does An AirTag Come With A Battery?

When you buy an AirTag, it comes with a pre-installed Panasonic CR2032 battery. It comes with some user and warranty documentation in the box too.

New AirTags come with a battery installed.

If you decide to shell out $29 for a new glossy white and polished stainless steel AirTag, here’s what you can expect for your hard-earned cash. 

Upon opening the sleek packaging, it will reveal a few informational documents. Pushing those to one side, you will find the AirTag all neatly wrapped in plastic. Removing the plastic serves two functions, first, it exposes the stainless steel face (which can easily be scratched), and second, it activates the pre-installed lithium battery that comes with an AirTag – and that’s it.

Unfortunately, an AirTag does not come with an extra battery included in the box, nor any accessory for attaching the AirTag to something.

How Long Will An AirTag Battery Last?

Apple has said that you can expect an AirTag battery to last about one year before needing to replace it. That said, an AirTag’s battery life will vary depending on its use.

How you use an AirTag and the features you use can affect an Apple AirTag’s battery life. Frequently pinging its location in the Find My app will affect how long the battery will last. Other things like environmental conditions and the battery brand also play a part in how long a battery will last.

  5. Next, replace the cover making sure that it aligns with the AirTag.
  6. Lastly, rotate the cover clockwise until it stops.

Note: If you do not hear a sound indicating that the new battery is connected, repeat step 4.
