Apple’s AirTags have revolutionized how we keep track of everyday items like keys, wallets, and luggage. But one common question many new AirTag users have is: do AirTags need to be charged? As an AirTag owner myself, I’m here to provide the definitive answer along with expert insight into AirTag battery life and replacement.
How Are AirTags Powered?
Non-Rechargeable Coin Cell Batteries
Unlike many tracking devices, AirTags do not have a built-in rechargeable battery. Instead, each AirTag is powered by a standard CR2032 coin cell battery, the same type commonly used in watches, car key fobs, and other small electronics. You may also be wondering, are AirTags magnetic and how they attach to items – check out our guide for more info.
When you purchase a new AirTag, it comes with the battery pre-installed and ready to use out of the box — no charging required. The AirTag has no charging port, as the battery is designed to be replaced, not recharged, when depleted.
One-Year Average Battery Life
According to Apple, the CR2032 battery in an AirTag should last about one year before needing replacement, based on everyday use. Several factors can impact actual battery life, including:
- How often the AirTag is in Lost Mode
- Ambient temperature exposure (learn more about AirTag heat resistance)
- Frequency and duration of separation alerts
- Number of devices connected to the Find My network near the AirTag
In my experience, an AirTag used to occasionally track keys or a backpack typically lasts the full year or more. AirTags that are triggered more frequently, like those attached to a dog collar or constantly misplaced wallet, may need a battery swap a bit sooner.
Checking AirTag Battery Level
Using the Find My App
Luckily, there’s an easy way to keep tabs on your AirTag’s remaining battery life so you’re not caught by surprise. Simply:
- Open the Find My app
- Tap the Items tab
- Select an AirTag from the list
- Look for the battery icon below the AirTag’s name
The battery icon provides a visual indicator of remaining power, much like your iPhone battery icon. When the battery icon is full, your AirTag has plenty of power left. If your AirTag is not working or connecting properly, a low battery could be the culprit — here’s a guide on troubleshooting AirTag connection issues.
Low Battery Notifications
If an AirTag battery is critically low, a notification like “[AirTag Name] Battery Is Low” will appear below the battery icon to alert you that it’s time to replace it. You’ll also receive a push notification and email to remind you.
It’s a good idea to regularly check your AirTags’ battery levels every month or so, especially if they are attached to less frequently used items, to avoid a dead battery catching you off guard.
Replacing an AirTag Battery
Compatible Battery Types
When it comes time to replace an AirTag battery, you’ll need a new CR2032 lithium 3V coin battery. These are widely available at drug stores, electronics stores, and online retailers. Some top brands include:
While cheaper off-brand CR2032 batteries can work, buying a high quality battery from a trusted brand will ensure your AirTag has a reliable power source.
Note: Apple recommends using CR2032 batteries without bitterant coatings, as the coating can interfere with the battery contacts. However, always keep AirTags out of reach of small children regardless of battery type.
Step-by-Step Replacement Instructions
Replacing an AirTag battery is a simple process you can do at home in under a minute by following these steps:
- Place the AirTag plastic side down on a flat surface.
- Press down on the stainless steel battery cover and rotate counterclockwise until it stops.
- Remove the battery cover and the old battery.
- Insert a new CR2032 battery positive side up.
- Replace the cover, aligning the three tabs on the cover with the slots on the AirTag.
- Rotate the cover clockwise until it locks in place.
Your AirTag will play a sound after battery installation to indicate it is powered on and ready to use. If you don’t hear a sound, remove the battery, wait 30 seconds, and reinstall to reset the AirTag.
Battery Safety Precautions
When handling AirTag batteries, keep the following safety guidelines in mind:
- Always keep batteries away from children and pets.
- Dispose of used batteries according to local regulations. Many retailers offer free battery recycling.
- Don’t mix old and new batteries.
- Store spare batteries in a dry place at normal room temperature away from metal objects.
- If a battery is swallowed, immediately seek medical help.
By following these precautions and using the correct type of battery, you can ensure your AirTag maintains a reliable power source without any issues.
AirTag Battery FAQs
Do AirTags come with a battery? Yes, a new AirTag comes with a preinstalled CR2032 battery that should last about a year before needing replacement.
Can you recharge an AirTag? No, AirTags are not rechargeable. When the battery is depleted, you must replace it with a new CR2032 lithium coin battery.
How do I know if my AirTag needs a new battery? You can check your AirTag battery level anytime in the Find My app. When the battery is critically low, you will see an in-app notification and receive an email and push alert.
Is changing an AirTag battery difficult? Not at all! To replace the battery, simply rotate the stainless steel battery cover counterclockwise, remove the old battery, insert a new CR2032 battery, and lock the cover back in place. The whole process takes less than a minute.
Can I use a bitterant coated battery in my AirTag? While a bitterant coated CR2032 battery will still power an AirTag, Apple advises against it as the coating can interfere with the battery contacts. It’s best to use a non-bitterant battery from a brand like Duracell or Energizer.
How often should I check my AirTag battery level? It’s a good practice to check your AirTag batteries once a month, especially for those attached to items you don’t use often, to make sure you aren’t surprised by a dead battery. You’ll also receive alerts when a battery is critically low.
Does Apple charge a monthly fee for AirTags? No, there are no monthly fees associated with using AirTags. However, you do need an Apple device to set up and use AirTags. Learn more about potential AirTag costs.
Can AirTags track location history? AirTags don’t store a history of all the places they’ve been. However, you can see an AirTag’s current and last known location in the Find My app. For more details, check out our AirTag location history guide.
What does it mean when an AirTag is “searching for signal”? If you see “searching for signal” in the Find My app, that means your AirTag is out of Bluetooth range of your device and any others in the Find My network. Here’s a more in-depth look at what AirTag signal issues mean and how to resolve them.
