No, Apple AirTags cannot be recharged. AirTags are powered by a replaceable CR2032 lithium coin cell battery, which typically lasts about one year. When the battery runs low, you simply replace it – there’s no built-in charging port, cable, or wireless charging capability.
How AirTag Power Works
Battery Type
- Model: CR2032
- Type: 3V lithium coin cell (non-rechargeable)
- Replacement: User-replaceable (no tools needed)
- Average lifespan: Around 12 months per battery
The CR2032 battery is the same type commonly used in watches, car key fobs, and remotes.
Why It’s Not Rechargeable
Rechargeable batteries (like lithium-ion cells) require internal charging circuitry and a charging port or wireless coil – which would add size, weight, and complexity.
Apple designed AirTags to be compact, low-maintenance, and inexpensive to power, so they use a disposable coin cell instead.
How to Replace an AirTag Battery
Replacing an AirTag battery takes less than a minute:
- Hold the AirTag with the stainless steel cover facing up.
- Press down on the metal cover.
- Turn counterclockwise until the cover stops turning.
- Remove the old battery.
- Insert a new CR2032 battery with the positive side (+) facing up.
- Press down until you hear a sound, confirming the AirTag has power.
- Replace the cover and turn clockwise until it locks.
After replacement, your AirTag reconnects automatically – there’s no need to re-pair it.
How to Know When to Replace the Battery
AirTags notify you when the battery is running low:
- Open the Find My app.
- Tap the Items tab.
- Select your AirTag.
- If the battery is low, a low battery warning will appear under its name.
You’ll also receive an iPhone notification when the battery is nearly depleted.
Battery Life Expectations
- Typical lifespan: ~1 year under normal use
- Heavy use (frequent sound alerts or Lost Mode): slightly shorter lifespan
- Minimal use: may last longer than 12 months
You can maximize battery life by keeping sound alerts and Lost Mode usage to a minimum.
Recommended Replacement Batteries
Use a standard CR2032 lithium battery from reputable brands such as Energizer, Panasonic, or Maxell.
⚠️ Avoid bitter-coated batteries.
Some CR2032 batteries (like Duracell’s “child-safe” versions) have a coating that can interfere with AirTag contacts and prevent it from powering on. Always use uncoated batteries for reliable performance.
What Happens If You Try to Recharge an AirTag
Since AirTags are not designed for recharging:
- There’s no port or coil for connecting a charger.
- Attempting to recharge the battery could damage it or cause leakage.
- The CR2032 cell is non-rechargeable – trying to recharge it is unsafe and not supported.
Always replace the battery instead of trying to recharge it.
Summary
- AirTags cannot be recharged – they use a replaceable CR2032 battery.
- The battery lasts about one year, depending on usage.
- When low, replace it with a new uncoated CR2032 coin cell.
- AirTags have no charging port or wireless charging feature.
- Replacing the battery is quick, safe, and keeps your AirTag running like new.
