Yes, AirTag batteries can be replaced, and it takes about 30 seconds

Apple AirTags use a standard CR2032 coin cell battery, the same type found in watches, calculators, and hearing aids. When your AirTag stops making sound or the Find My app warns you the battery is low, you can buy a replacement battery at any pharmacy, grocery store, or online retailer for $3 to $8 and swap it yourself. You do not need tools, a technician, or an Apple Store visit.

The battery lasts roughly one year under normal use — Apple estimates 12 months. If you use your AirTag heavily (checking its location multiple times daily), the battery may drain faster. If you rarely check it, it may last longer. The Find My app will notify you when the battery is running low, usually a few weeks before it dies completely.

Key Takeaways

  • AirTags use CR2032 batteries, which are inexpensive and sold everywhere batteries are stocked.
  • Replacing the battery takes under a minute and requires no tools — you twist the back cover off and drop the new battery in.
  • The Find My app will alert you when the battery is low, giving you time to buy a replacement before it dies.
  • A fresh CR2032 battery costs between $3 and $8 and lasts approximately one year.

Where to buy CR2032 replacement batteries

CR2032 batteries are one of the most common battery types in the world. You can find them at pharmacies (CVS, Walgreens), grocery stores (most have a battery aisle), dollar stores, Target, Walmart, and online at Amazon. A single battery typically costs $3 to $5 in a store; multi-packs online are often cheaper per battery but require buying more than one.

When you buy, look for the label "CR2032" on the package. Some sellers also list it as "2032" or "DL2032." The battery is small — about the size of a dime — so check that you have the right one before you leave the store. Avoid buying the cheapest option if the brand is unfamiliar; a reputable brand like Energizer, Duracell, or Panasonic costs only slightly more and is more likely to last the full year.

How to replace the battery step by step

Hold your AirTag with the white plastic side facing up. On the back (the metal side), you will see a small circular cover. Press down on this cover and twist it counterclockwise — it will come loose after about a quarter turn. The cover will pop off in your hand.

Inside, you will see the old battery sitting flat in a small metal cup. Lift it out with your fingernail or a plastic tool (a credit card edge works). Drop the new CR2032 battery in with the positive side facing up — the side with the "+" symbol should face toward you. Press the metal cover back on and twist it clockwise until it clicks. The AirTag will beep to confirm the battery is installed correctly.

If the AirTag does not beep, the battery may be installed upside down. Pop the cover off again, flip the battery, and try once more. Once it beeps, you are done. The Find My app will update within a few minutes and show the battery as full.

What to do with the old battery

Do not throw a used CR2032 battery in the trash. Batteries contain materials that can harm the environment if they end up in a landfill. Most pharmacies and retailers that sell batteries also accept used batteries for recycling at no charge — ask at the customer service desk or look for a battery recycling bin near the checkout.

If your local store does not have a program, search "battery recycling near me" online or check Earth911.com, which has a database of recycling locations by zip code. Some municipalities also have hazardous waste collection days where you can drop off batteries for free.

Signs your AirTag battery is dying

The Find My app is the most reliable indicator. Open the app, tap the Items tab, select your AirTag, and scroll down to see the battery level. When it drops below 10 percent, the app will show a red battery icon and send you a notification. At that point, you have a few weeks before the battery is completely dead.

If you do not check the app often, you may notice the AirTag stops making sound when you press the button on the back. This usually means the battery is nearly gone. Some people also notice the AirTag takes longer to connect to the Find My network, though this is less common and can also be caused by other issues.

Can you replace the battery at an Apple Store?

Apple Stores do not offer battery replacement for AirTags. The company designed the battery to be user-replaceable specifically so you would not need to visit a store or pay a service fee. If your AirTag is damaged and the battery cover will not come off, or if the AirTag itself is not working, you can contact Apple Support or visit an Apple Store to discuss repair or replacement options — but for a straightforward battery swap, you are on your own (and that is a good thing, since it saves you time and money).

This design choice reflects Apple's philosophy that some repairs should remain straightforward and inexpensive for the user. You will not find a battery replacement service at the Genius Bar, and you should not expect one — the whole point is that you handle it yourself in seconds at home.

How long does a CR2032 battery last in an AirTag?

Apple states that a CR2032 battery lasts approximately one year in an AirTag under normal use. "Normal use" means checking the location of your AirTag a few times per week. If you check it multiple times per day, the battery will drain faster — possibly in 8 to 10 months. If you rarely use the Find My app, the battery may last 14 to 16 months.

The battery life also depends on how far your AirTag is from your other Apple devices. An AirTag that is frequently near your iPhone, iPad, or Mac will use less power than one that is far away and relying on the Find My network. Extreme temperatures can also shorten battery life, so avoid leaving your AirTag in a hot car or freezing garage for long periods.

Frequently Asked Questions

Can I use a different type of battery in my AirTag?

No. AirTags are designed for CR2032 batteries only. Other coin cell batteries, even if they fit physically, may have different voltage or chemistry and could damage the AirTag or fail to work. Stick with CR2032.

What if my AirTag battery cover is stuck?

Try twisting it with a bit more force — sometimes the cover is just tight from the factory. If it still will not budge, wrap a rubber band around the cover for better grip and try again. Do not use pliers or tools that could scratch the metal. If it remains stuck, contact Apple Support.

Will replacing the battery reset my AirTag?

No. Swapping the battery does not erase the AirTag's settings or unpair it from your account. It will reconnect to Find My automatically within a few minutes. Your location history and any custom name you gave the AirTag will remain unchanged.

Is it safe to handle a CR2032 battery with bare hands?

Yes, CR2032 batteries are safe to touch. They are not radioactive and do not pose a shock risk. Wash your hands after handling if you prefer, but it is not necessary. Keep batteries away from small children and pets, as swallowing one can be dangerous.

Can I buy rechargeable CR2032 batteries for my AirTag?

Rechargeable CR2032 batteries exist, but Apple does not recommend them for AirTags. Rechargeable versions have slightly lower voltage and may not power the AirTag reliably. Stick with standard single-use CR2032 batteries for the best performance and longest lifespan.
