air tag battery

Whether you’re using your Apple Air Tag to keep track of your keys, wallet, luggage, or even child, you’re probably wondering, “how long will it last?”

An Apple Air Tag Battery should last for around one year. After that, the batteries will then need to be changed. Unfortunately, there’s no way to recharge them, nor do they come with a charging port.

Stick around to learn more about how long an Apple Air Tag battery lasts and more!

How Long Do Apple Air Tags Battery Last?

According to Apple, an Air Tag should last a year, maybe more, depending on how often you use them. Since they’re powered by lithium CR2032 batteries, the tags can’t be recharged once the battery dies.

That said, the one-year test was carried out on batteries used daily with four play-sound events and one Precision-find event—both of which are the main features of an Air Tag.

What Impacts the Lifespan of an Apple Air Tag Battery?

Even though the average battery life of an Apple Air Tag is approximately one year, there are certain factors that might impact its longevity.

For instance, if you typically use your Air Tag more than its average test use, the battery will die out quicker, and vice versa.

Certain environmental factors might also cut the battery’s life short. For example, Apple Air Tags should operate at an average temperature of -4 to 140 degrees Fahrenheit for best results.

Luckily, Air Tags are waterproof. Since they’re rated an IP67 for water and dust resistance, the tracking devices can withstand a three-foot submersion in water for about half an hour.

Nevertheless, extreme temperatures can hinder your Air Tag’s battery life. It can even cause the battery to shut down completely.

How to Keep Track of Your Apple Air Tag’s Battery Life?

The good news is you don’t need to worry too much about losing track of your Air Tag’s battery life. Apple added a feature that sends notification alerts when the battery is about to die.

Plus, if the battery is about to die, you’ll notice it the next time you use the Air Tags because they’ll operate slower than usual.

Apart from that, other factors can also help indicate your Air Tag’s low battery status. Take a look.

  1. First, you want to make sure your device is linked to the Find My app. Then, for added convenience, check to make sure your Wi-Fi or cellular data connection is working at optimal speeds.
  2. Go to the Find My app from your searching Mac device. It should show you a list of all the other tracked Apple devices.
  3. Locate the “Items” tab near the bottom. There, you should find a list of the Air Tags you’re connected to.
  4. Tap on the one you’re searching for.
  5. Look at the battery icon below under the Air Tag’s given name to see how full it is.

How to Get the Most Out of Your Apple Air Tag’s Battery Life?

In some cases, you can save up your Air Tag’s battery. The best way to do that is to activate it only when needed.

This can be when you’re traveling and need to track your luggage. Or maybe you prefer using it when going out to keep track of your wallet. Either way, just remember to disconnect it when it’s not in use.

In addition, you can also just set an 11-month reminder after activating your Air Tag to keep track of the battery life.

How to Change an Apple Air Tag Battery?

Now, what if your battery’s low? You can’t recharge it, which means you’ll need to get a new one.

Luckily, replacing the battery is a simple process. Check out our easy step-by-step guide below.

Step 1: Find a New Battery

The first thing you need to do is purchase a new lithium CR2032 coin-shaped battery. Thankfully, you don’t need to go to an Apple store to get them for a steep price since they’re not proprietary.

In other words, any lithium CR2032 battery will do.

Simply head to your nearest electronics store, navigate the battery section, and find the CR2032 3V coin batteries. You can also purchase them online from Amazon.

Apple Air Tag Battery Complications

Before making your purchase, you need to ensure that the new battery doesn’t contain any bitter coatings.

Although the coating prevents children from ingesting the battery, it might not allow the Air Tag to function properly.

Step 2: Remove the Old Battery

To dispose of the old battery, you need to turn the Air Tag to its silver stainless steel side, where there’s an Apple logo. Next, make sure the device is out of any casing.

Next, you’ll want to use your thumbs to press down on the battery cover. Then, turn the silver cover counterclockwise. Once there’s no more room to turn, remove your fingers.

The cover should be off by now to reveal the old battery inside. Now, carefully take it out of the Air Tag.

Step 3: Insert the New Battery

Take the new battery and place it inside the Air Tag’s empty cavity. Make sure the positive sign is facing upwards, and you hear a click once it’s inside.

Put the cover back in by positioning all three tabs into their complementary three slots of the Air Tag. Then, turn the lid around clockwise until it’s fully sealed.

We recommend discarding old batteries by giving them to a certified electronics waste recycler rather than throwing them in the trash.


So, how long do Apple Air Tag batteries last? Well, it depends, but the average time span is about a year. The good news is that keeping track of your easy-to-lose belongings has never been easier with Apple’s Air Tag product.

The best part is that you don’t need to constantly worry about battery loss since there’s about a year’s worth of power already guaranteed.

A notification alert or reminder makes it easy to keep track of how long an Air Tag battery will last. Then, after a year has gone by, you can replace them with new batteries. It’s foolproof, cost-effective, and only takes a few minutes
