Why Your AirTag Needs the Right Battery
Think of the battery as the heart of your AirTag. Without it, your AirTag can’t send out its Bluetooth signal, which is how your iPhone or other Apple devices can locate it using the Find My network. When the battery is low or dead, your AirTag essentially goes silent, leaving you in the dark.
Choosing the correct battery ensures your AirTag performs at its best. It means reliable tracking, long battery life, and avoiding any performance hiccups. Apple designs its products to work seamlessly with specific components, and the battery is no exception. Using the right one means you get the intended performance and longevity.
The Official Battery Type: CR2032
Here’s the simple, direct answer: The battery type for your Apple AirTag is the widely available CR2032 lithium coin cell battery.
This battery is pretty standard and can be found in countless electronic devices, from car key fobs to small home gadgets. It’s a 3-volt battery, known for its reliable power output and impressive lifespan, which is exactly what you need for a device that’s meant to be on guard for extended periods.
What Exactly is a CR2032 Battery?
Let’s break down what the “CR2032” label means, so you feel confident picking one up at the store:
- CR: This code indicates the battery chemistry. “C” stands for “Cylindrical” and “R” stands for “Alkaline” or, in this lithium context, “Primary Lithium.” These are non-rechargeable batteries.
- 20: The first two digits refer to the battery’s diameter in millimeters. So, a CR2032 battery is approximately 20mm wide.
- 32: The last two digits refer to the battery’s thickness in tenths of a millimeter. So, a CR2032 battery is about 3.2mm thick.
In short, CR2032 just describes the size and type of this very common coin cell battery. It’s a powerful little disc that provides consistent energy.
Why Apple Chose the CR2032 for AirTags
Apple didn’t pick the CR2032 at random. Several factors make it an ideal choice for AirTags:
- Longevity: CR2032 batteries are known for their long shelf life and ability to provide power for a considerable amount of time. Apple states your AirTag battery should last about a year.
- Availability: This is probably the biggest win for users. CR2032 batteries are sold almost everywhere, from supermarkets and convenience stores to pharmacies and big-box electronics retailers. You can easily find them when you need a replacement.
- Standardization: Because it’s such a common battery, you’re likely to find good quality ones from reputable brands. This ensures reliable performance.
- Power Output: The 3-volt output is perfectly suited for the low-power requirements of the AirTag’s components.
- Compact Size: Its slim, coin-like shape allows the AirTag to maintain its small, discreet form factor.
Understanding AirTag Battery Performance and Replacement
One of the best things about your AirTag is how long the battery lasts. Most users can expect about a year of usage before needing to swap it out. This is great because it means you don’t have to constantly worry about charging or replacing the battery.
When to Replace Your AirTag Battery
Your iPhone will alert you when the battery on your AirTag is running low. You’ll usually see a notification. You can also check the battery level at any time by opening the Find My app, selecting “Items,” tapping on your AirTag, and looking for the battery icon.
Don’t wait until you desperately need to find something to realize the battery is dead! When you get that low battery notification, it’s a good idea to have a replacement CR2032 battery on hand.
How to Replace the AirTag Battery: A Step-by-Step Guide
Replacing the battery in an AirTag is quite simple, but it requires a little care, especially with newer AirTags that have a child-resistant coating on the battery.
Tools You’ll Need:
- A new CR2032 lithium coin cell battery.
- Your AirTag.
Steps for Battery Replacement:
- Press and Twist: Take your AirTag and place it face down on a soft surface (like a cloth or your palm) so the white side is up. Using your thumb and index finger, firmly press down on the polished stainless steel battery cover. While maintaining pressure, twist the cover counter-clockwise (to the left) until it stops.
- Remove the Cover: Once it has twisted as far as it will go, lift the battery cover off. You should now see the old CR2032 battery inside.
- Remove the Old Battery: Gently push the battery out. You can often do this by tilting the AirTag carefully, or by gently prying under one edge of the battery with a fingernail or a non-metallic, thin tool. Be careful not to damage the internal components.
- Insert the New Battery: Take your new CR2032 battery and insert it with the positive (+) side facing up. The battery should sit snugly in place.
- Replace the Cover: Align the three tabs on the battery cover with the three slots on the AirTag. Press down firmly on the cover and twist it clockwise (to the right) until it locks into place. You should feel and hear it click once it’s secure.
- Test It: After replacing the battery, you should hear a chime. This confirms the AirTag is powered up and ready to go. You can also check its status in the Find My app.
Important Safety Note on Child-Resistant Coatings:
Some CR2032 batteries come with a bitter, child-resistant coating on them. While good for safety if accidentally swallowed, this coating can sometimes make it just slightly harder to make good contact with the AirTag’s terminals. If your AirTag doesn’t seem to register the new battery immediately, ensure the battery is seated correctly and try wiggling it slightly, or try a CR2032 battery without the coating if you have one available.

Choosing the Right CR2032 Battery: What Brands to Look For
While CR2032 is the type of battery, not all CR2032 batteries are created equal. For something as important as tracking your belongings, opting for reputable brands is a smart move.
Recommended Brands
You’ll find many brands offering CR2032 batteries. Some of the most reliable and widely available include:
- Energizer
- Duracell
- Panasonic
- Sony
- Amazon Basics (often a good value for reliable performance)
What to Avoid
While it might be tempting to buy the cheapest batteries you can find, especially from unbranded sources, it’s generally not worth the risk for your AirTag:
- Unknown Brands: Batteries from companies you’ve never heard of might have inconsistent power output or a shorter lifespan.
- Counterfeit Batteries: Be wary of deals that seem too good to be true, especially online. Counterfeit batteries can be unreliable and even dangerous.
- Old Stock: Batteries lose their charge over time. Try to buy from retailers that have good stock turnover to ensure you’re getting fresh batteries.
Battery Quality vs. Price
Let’s look at a quick comparison:
| Factor | Reputable Brand CR2032 | Generic/Unbranded CR2032 |
|---|---|---|
| Reliability | High – consistent power output | Variable, often lower |
| Lifespan | Meets or exceeds expected performance | Often shorter than advertised |
| Availability | Widely available in most stores | May only be found online or in specialty shops |
| Price | Slightly higher, but offers good value | Lower upfront cost |
| Safety | Generally higher safety standards | Could be lower |
For your AirTag, the small difference in price for a quality battery is well worth the peace of mind knowing it will last as expected and perform reliably.
Can I Use Rechargeable Batteries in My AirTag?
This is a common question, especially with the rise of rechargeable technology. However, for your AirTag, the answer is generally no. AirTags are designed to use non-rechargeable lithium coin cell batteries, specifically the CR2032.
While rechargeable CR2032 batteries exist, they often have a slightly lower voltage (typically around 1.5V to 1.9V) compared to the standard 3V of a primary lithium CR2032. This lower voltage might not provide enough power for the AirTag to function correctly or may significantly reduce its performance and lifespan. Furthermore, the charging circuitry required for rechargeable batteries would add bulk and complexity that Apple designed the AirTag to avoid.
It’s always best to stick with the manufacturer’s recommendation for non-rechargeable CR2032 batteries to ensure optimal performance and longevity of your AirTag.
Disposing of Used Batteries Responsibly
When you replace your AirTag’s battery, you’ll have a used CR2032 battery. Lithium batteries, like all batteries, should be disposed of responsibly to protect the environment.
- Never throw them in the regular trash. They can contain materials that are harmful if they end up in landfills.
- Tape the terminals: Before disposing of a lithium coin cell, it’s a good practice to place a small piece of clear tape over the positive (+) side of the battery. This helps prevent accidental short circuits, which can pose a fire risk.
- Find a Battery Recycling Point: Many retail stores that sell batteries (supermarkets, electronics stores, hardware stores) have designated battery recycling bins. You can also check with your local waste management services or search online for battery recycling locations in your area. For instance, resources like Call2Recycle (a non-profit battery stewardship organization in North America) can help you find local drop-off points. You can visit Call2Recycle.org to find your nearest location.
Proper disposal ensures these materials can be handled safely and reused where possible.
