"Learn How to Change Your AirTag Battery"

Understanding Your AirTag Battery Type and Lifespan

Apple AirTags use a single CR2032 coin cell battery, which is a common battery type found in many consumer devices like watches, calculators, and remote controls. This small, round battery measures about 20 millimeters in diameter and 3.2 millimeters in thickness. The CR2032 designation comes from its specific dimensions and chemical composition—it's a lithium coin battery that provides reliable power for tracking devices.

The battery in your AirTag typically lasts approximately one year under normal usage conditions. Apple's testing shows that a new CR2032 battery powers an AirTag through roughly 12 months of regular operation, though this timeline can vary based on how frequently your AirTag connects to nearby Apple devices and how often it uses its speaker or other features. If you own multiple AirTags or use them in areas with dense Apple device populations, your battery may last the full year or potentially longer.

When your AirTag battery is running low, you'll receive a notification on your iPhone, iPad, or Mac. This notification appears in the Wallet app or Find My app, alerting you that it's time to consider a battery replacement. Some users report receiving this notification when the battery still has several weeks of charge remaining, giving you adequate time to plan the replacement without your AirTag losing functionality.

Understanding battery lifespan helps you plan maintenance schedules. Many users find it helpful to replace their AirTag batteries during seasonal transitions—for example, when changing their clocks for daylight saving time or during regular phone system updates. This approach creates a predictable maintenance routine rather than dealing with unexpected low-battery notifications.

Practical Takeaway: Plan to replace your AirTag battery approximately once per year, and don't wait until you receive a low-battery warning to purchase a replacement CR2032 battery. Having a spare battery on hand prevents service interruptions when multiple AirTags need replacement simultaneously.

Locating and Purchasing the Correct Replacement Battery

Before you begin the replacement process, you need to obtain a CR2032 battery. These batteries are widely available and inexpensive, typically costing between $3 and $8 depending on brand and quantity. You can purchase CR2032 batteries from numerous retailers both in-store and online, making them easy to find when you need them.

Common places to buy CR2032 batteries include pharmacy chains like CVS and Walgreens, where they're usually located in the pharmacy section near other health and personal care items. Major retailers such as Target and Walmart stock CR2032 batteries in their electronics or general merchandise departments. Online retailers including Amazon, Best Buy, and eBay offer bulk purchase options, which can be economical if you own several AirTags or other devices that use this battery type.

When shopping for a replacement battery, look for the "CR2032" designation on the packaging. The battery should be labeled as a lithium coin cell battery. While various manufacturers produce CR2032 batteries—including Energizer, Duracell, Panasonic, and store-brand options—most perform similarly in AirTag devices. You don't need a premium brand; standard CR2032 batteries work reliably in Apple AirTags.

Consider buying in bulk if you own multiple AirTags. A pack of four to eight CR2032 batteries typically costs only slightly more than individual batteries, and having extras on hand means you won't need to make a special shopping trip when multiple devices need replacement. Some users purchase a year's supply at once, using this as their planned maintenance schedule.

Avoid purchasing batteries from unknown online sellers or unmarked packages, as counterfeit batteries occasionally appear in the marketplace. Stick with recognized retailers and established brands to ensure battery quality and longevity. Battery expiration dates, while rarely an issue with CR2032 batteries due to their minimal discharge rate in storage, should be checked if you're purchasing older inventory.

Practical Takeaway: Buy CR2032 batteries from established retailers, consider purchasing in small bulk quantities to reduce shopping trips, and keep spare batteries stored in a cool, dry location for whenever your AirTags need replacement.

Preparing Your AirTag for Battery Removal

Before you remove the battery from your AirTag, take a moment to prepare and understand the device's physical design. An AirTag consists of a white plastic disc approximately the size of a large coin, with a stainless steel or gold-colored back plate. The back plate is not permanently sealed—it's designed to be removed by applying rotational pressure, allowing you to access the battery compartment inside.

Start by locating the seam between the white plastic top and the metal back plate. This seam runs around the circumference of the device and is where you'll apply pressure to separate the two parts. The seam is subtle but visible if you look carefully at the edge where the white and metal portions meet.

Before opening your AirTag, decide where you'll work. A clean table or desk with good lighting provides an ideal workspace. The components inside are small—the battery itself is tiny, and the internal components are delicate. Having adequate lighting helps you see exactly what you're doing and prevents dropping small parts.

Some users find it helpful to have a small container nearby to hold the back plate once it's removed, keeping all parts organized and preventing loss. A small bowl or cup works well for this purpose. If your AirTag is attached to a keychain or item, consider removing it from any attachments first, as this provides better access to the back plate.

Gather any tools you might need. While you technically only need your hands to open an AirTag, some people find that a coin or flat-edged object like a guitar pick helps apply pressure to the seam. Avoid using sharp objects or screwdrivers, as these can damage the plastic or metal components. Your fingernail or a coin usually provides sufficient leverage.

Practical Takeaway: Set up a clean, well-lit workspace before opening your AirTag, and have a small container ready to hold the back plate so you don't misplace it during the battery replacement process.

Opening the AirTag and Removing the Old Battery

Now that you're prepared, you're ready to open your AirTag. Hold the device with the white plastic side facing up and the metal back plate facing down. Position the AirTag so that the seam between the white and metal portions is easily accessible.

Apply firm, steady pressure downward on the white plastic while simultaneously rotating it counterclockwise. The metal back plate should remain stationary as you rotate the white portion. You don't need to use extreme force—firm, controlled pressure is more effective than forceful twisting. Rotate approximately one-quarter turn, or about 90 degrees.

As you rotate, you should feel slight resistance, and then the white plastic will begin to separate from the metal back plate. Continue rotating until you can see a clear gap between the two pieces. Once there's visible separation, you can stop rotating and instead gently pry the white plastic away from the metal plate using your fingernail or the edge of a coin.

Inside the AirTag, you'll see the small CR2032 battery sitting in a circular battery compartment. The battery is held in place by the battery compartment itself—it doesn't have springs or other retaining mechanisms that complicate removal. Above the battery, you may see a small circuit board with minimal components. This is normal and requires no interaction from you.

To remove the old battery, simply slide your fingernail or a coin edge under the edge of the battery and gently lift it out of its compartment. The battery will come free easily, as there's no adhesive holding it in place. If the battery seems stuck, don't force it—try working from a different edge of the battery until it lifts free.

Once removed, examine the battery compartment briefly to ensure it's clean. If you see any dust or debris, you can gently wipe the compartment with a dry cloth. Don't use liquids or cleaning solutions, as moisture inside your AirTag can damage the electronics.

Practical Takeaway: Open your AirTag by rotating the white plastic counterclockwise while applying downward pressure, and remove the old battery by gently lifting it from its compartment with your fingernail or a coin edge.
