AirTags don’t need to be recharged. Instead, they run on a replaceable coin-cell battery that lasts for about a year. This means you can enjoy the convenience of tracking your essentials—like keys, bags, or an AirTag wallet—without worrying about charging them every few days. For many users, this is a major advantage over other Bluetooth trackers that rely on built-in rechargeable batteries.
What powers an AirTag and how long does it last?
Apple’s AirTags use a CR2032 lithium coin battery—yes, the same small disc battery you might have seen in garage remotes or kitchen scales. This battery provides enough juice to keep the AirTag running for roughly 12 months under normal usage. You’ll receive a notification on your iPhone when the battery is low, giving you plenty of time to swap it out.
Key points:
- AirTags use a CR2032 coin cell battery
- Battery life is around 12 months
- No recharging required
- Easy to replace
This simple power setup is part of what makes AirTags so appealing. You don’t need to pack a charging cable or set reminders. Just set it, forget it—and replace it once a year.
How do you know when an AirTag battery is low?
Your iPhone will alert you with a notification when the AirTag battery needs replacing. It doesn’t show a percentage like your phone or headphones, but once the battery starts running low, you’ll get a clear message.
You can also check manually:
- Open the Find My app.
- Tap on your AirTag.
- If the battery is low, you’ll see a “Low Battery” message under the device’s name.
This simple system removes guesswork and ensures you’re not caught off guard, especially if your AirTag is keeping tabs on something important—like your luggage or a slimline AirTag wallet tucked inside a passport holder.
Can AirTag batteries be replaced?
Yes, and it’s easy. One of Apple’s smartest design decisions with the AirTag is making the battery replaceable without tools. Just press and twist the back of the AirTag counterclockwise to open the battery compartment. Pop in a new CR2032 battery and twist it shut.
Important tip: Avoid batteries with bitter coatings (often sold as child-safe), as they may not work properly with AirTags due to poor contact.
Why don’t AirTags use rechargeable batteries?
There’s a clear reason Apple opted for disposable coin batteries over rechargeable ones: convenience. Rechargeables would require a charging port or wireless charging setup, increasing the device size and price. AirTags are meant to be discreet and low-maintenance—especially when hidden inside accessories like wallets or bags.
By using a replaceable coin battery:
- The design stays sleek and minimal
- Users aren’t tethered to charging cables
- The AirTag remains waterproof (IP67 rated)
In short, Apple prioritised simplicity and user experience over unnecessary complexity—something many owners appreciate.
Are there risks with the battery design?
Like any product using coin-cell batteries, there are safety considerations—especially around young children. The CR2032 battery can pose a choking or ingestion hazard. That’s why many accessories like AirTag wallets or keyrings feature secure enclosures that require some effort to open.
When handled properly, the battery system is safe, practical, and eco-conscious when disposed of correctly. It’s also worth noting that battery recycling options are widely available across Australia at local supermarkets and recycling centres.
Can AirTag battery life vary depending on usage?
Absolutely. While the 12-month estimate is standard, real-world battery life depends on:
- Ping frequency: The more often you trigger a sound or locate it, the more battery it uses.
- Out-of-range alerts: Constant searching or use in areas with poor signal may drain power faster.
- Environmental conditions: Cold weather can reduce battery efficiency.
For those using an AirTag wallet that rarely moves from a bag or jacket, you may even squeeze out a few extra months.
Are there alternatives that use rechargeable batteries?
There are. Brands like Tile and Chipolo offer trackers with rechargeable or USB-charging options. However, these usually need to be plugged in every few weeks and lack Apple’s native Find My integration, which makes AirTags uniquely powerful for iPhone users.
For example, only AirTags tap into Apple’s massive crowd-sourced tracking network—using anonymous pings from millions of Apple devices to help locate lost items, even from far away.
FAQs
How much does a replacement AirTag battery cost?
A single CR2032 battery typically costs between $2–$5 in Australia. You can find them at most supermarkets, pharmacies, or online stores. It’s best to buy name-brand batteries like Duracell or Energizer for reliability.
Do I need to pair my AirTag again after changing the battery?
No. Once you replace the battery, the AirTag reconnects automatically to your iPhone. There’s no need to reset or reconfigure anything.
Can I see exact battery levels in the app?
No, Apple doesn’t show a battery percentage. You’ll only be notified when the battery is low, which gives you time to replace it without losing tracking functionality.
Final thoughts
So, do AirTags need to be charged? Not in the traditional sense. Their coin-cell battery system offers a worry-free alternative to cable-charging trackers. Whether you’re using an AirTag wallet to keep tabs on your essentials or attaching one to a pet collar or suitcase, you can trust it to keep working silently in the background for a full year.
