An AirTag is designed to work quietly in the background, helping you keep track of your keys, wallet, luggage, and other everyday essentials without much maintenance. However, like any battery-powered device, it won't last forever. Whether you've recently started using an AirTag or you've received a low battery notification, understanding how long it lasts and when it needs a replacement can help you avoid interruptions and keep your belongings protected.
In this guide, you'll learn how long do AirTags last, what affects their battery life, and how to replace the battery in just a few simple steps. We'll also explain which battery type to use, how to tell when it's running low, and share practical tips to help maximize battery life so your AirTag continues working reliably whenever you need it most.
How Long Does AirTag Battery Last?
An AirTag battery typically lasts about one year before it needs to be replaced. That's possible because AirTags are designed to be extremely power efficient. Unlike GPS trackers that continuously transmit their location, an AirTag spends most of its time in a low-power state and only communicates when necessary using Bluetooth and Apple's Find My network. This allows it to provide reliable tracking for months on a single CR2032 coin-cell battery without needing to be recharged.
While Apple's one-year estimate is accurate for most users, battery life can vary depending on how you use your AirTag. Frequently playing sounds, using Precision Finding, or relying on Lost Mode may reduce battery life slightly, although the difference is usually minimal. When the battery begins running low, your iPhone will send a notification well in advance, giving you plenty of time to replace it and continue tracking your belongings without interruption.
Can You Recharge an AirTag?
No, AirTags can't be recharged. Instead of using a built-in rechargeable battery, every AirTag is powered by a replaceable CR2032 coin-cell battery. Once the battery runs low, you simply remove the back cover, swap in a new battery, and your AirTag is ready to use again. The entire process takes less than a minute and doesn't require any special tools.
Apple chose a replaceable battery to keep AirTags compact, lightweight, and easy to maintain. Since a single battery typically lasts about a year, most users only need to replace it occasionally rather than charging it every few days or weeks. Your iPhone will notify you when the battery is running low, so you'll have plenty of time to pick up a replacement before your AirTag stops working.
What Battery Does an AirTag Use?
Apple AirTags are powered by a CR2032 3V lithium coin-cell battery, a common battery that's widely available in supermarkets, electronics stores, pharmacies, and online. Because it's such a standard battery type, finding a replacement is usually quick and inexpensive, no matter where you are.
Although any compatible CR2032 battery may fit, Apple recommends choosing one without a bitter coating, as certain coated batteries can interfere with the electrical contacts inside the AirTag and prevent it from working properly. Under normal use, a single battery lasts about a year before it needs replacing, making AirTags one of the lowest-maintenance tracking devices available. Combined with the low cost and wide availability of CR2032 batteries, keeping your AirTag powered throughout the year is both simple and affordable.
How to Replace an AirTag Battery
Replacing an AirTag battery is quick and doesn't require any special tools or technical knowledge. Since AirTags use a replaceable CR2032 coin-cell battery instead of a rechargeable one, the entire process usually takes less than a minute. Once you've installed a fresh battery, your AirTag will continue working as normal, allowing you to keep tracking your belongings without having to pair it again.

Step 1: Remove the Back Cover - Hold the AirTag with the stainless steel side facing up. Press down firmly on the metal cover using two fingers and rotate it counterclockwise until it stops. Lift the cover off and set it aside.
Step 2: Take Out the Old Battery - Remove the old CR2032 battery from the AirTag. If you're disposing of it, be sure to recycle it according to your local battery recycling guidelines rather than throwing it in the regular trash.
Step 3: Insert the New Battery - Place a new CR2032 3V lithium coin-cell battery into the AirTag with the positive (+) side facing up. When the battery is properly installed, you'll hear a chime confirming that the AirTag has power.
Step 4: Reattach the Cover - Align the three tabs on the stainless steel cover with the slots on the AirTag. Press the cover down and rotate it clockwise until it locks into place. Your AirTag is now ready to use, with all of your settings and Find My information remaining exactly as they were before the battery replacement.
Step 5: Check That Your AirTag Is Working - Open the Find My app to confirm your AirTag is connected and working properly. You can also use Play Sound to verify the new battery is installed correctly. If it doesn't respond, check that the battery is inserted properly and is compatible with AirTag.
How to Check AirTag Battery Status
Apple makes it easy to monitor your AirTag's battery, so you won't have to guess when it's time for a replacement. Instead of displaying an exact battery percentage, the Find My app automatically alerts you when the battery starts running low, giving you plenty of time to replace it before the AirTag stops working.
To check your AirTag, open the Find My app on your iPhone and select the Items tab. Tap the AirTag you want to view to access its details. If the battery is in good condition, no warning will appear. When it's nearing the end of its lifespan, you'll see a Low Battery message, indicating it's time to install a new CR2032 battery. For most users, this notification appears roughly once a year under normal everyday use.
Best Alternatives to AirTags
AirTags are a reliable way to keep track of everyday belongings, but they're not the only option. If you're looking for more than a standalone tracker, several accessories combine Apple Find My technology with practical everyday features like wallets, phone stands, and tripods, helping you carry less while getting more from a single device.
Trackable Snap-on Stand & Wallet
The Trackable Snap-on Stand & Wallet is a smart alternative to carrying both an AirTag and a separate wallet. With built-in Apple Find My technology, it lets you track your wallet directly from the Find My app while also functioning as a MagSafe wallet and adjustable phone stand. That means fewer accessories to carry without sacrificing functionality. Despite its slim profile, it securely holds up to three cards, weighs just 60 g (2.1 oz), and measures only 8.3 mm (0.33 in) thick.
The foldable design supports both portrait and landscape viewing, making it ideal for FaceTime calls, streaming videos, or browsing hands-free. Strong MagSafe magnets keep it securely attached to your iPhone, while the integrated tracker provides peace of mind if your wallet is ever misplaced. It's a practical upgrade for anyone looking to simplify their everyday carry.
Trackable Field Wallet
The Trackable Field Wallet is designed for people who need more than a slim card holder. It combines the convenience of a MagSafe wallet with built-in Apple Find My technology, allowing you to keep track of your everyday essentials without carrying a separate AirTag.

A convenient pull-tab provides quick access to your most-used cards, while the foldable design also functions as a sturdy stand for both portrait and landscape viewing.
Wrapped in durable MOVAS™ vegan leather and secured with powerful MagSafe magnets, it stays firmly attached to your iPhone throughout the day.

Tips to Make an AirTag Battery Last Longer
Although an AirTag battery is designed to last about a year, a few simple habits can help you get the most out of it. Since AirTags are already optimized for low power consumption, there isn't much maintenance required, but reducing unnecessary activity can slightly extend battery life. Avoid repeatedly using features like Precision Finding or Play Sound unless you need them, as frequent use can drain the battery faster.
It's also a good idea to keep your AirTag clean and dry, as dirt or moisture around the battery compartment can affect performance over time. Finally, use a high-quality CR2032 battery when it's time for a replacement and avoid batteries with a bitter coating, which may not work properly with AirTags. With normal use and a quality battery, most users can expect close to Apple's one-year battery estimate.
Wrap Up!
AirTags are designed to be simple, low-maintenance trackers, and their battery reflects that. With a lifespan of around one year, a widely available CR2032 battery, and a replacement process that takes less than a minute, keeping your AirTag powered is quick and inexpensive. As long as you replace the battery when your iPhone alerts you, your AirTag can continue helping you locate your everyday essentials without interruption.
If you're looking for a more streamlined alternative, accessories with built-in Apple Find My technology offer the same tracking convenience while adding practical features like a wallet, phone stand, or tripod. Whether you stick with a traditional AirTag or choose an all-in-one tracking accessory, understanding how AirTag batteries work will help you get the most from your device and ensure it's always ready when you need to find your belongings.
