No, AirTags cannot be recharged. Unlike many modern electronic devices, Apple designed AirTags to use a replaceable coin cell battery instead of a rechargeable one. This design keeps the device lightweight, simple, and long-lasting – while avoiding the need for charging cables or docks.
AirTag Battery Type
Each AirTag uses a CR2032 lithium coin cell battery, a common type found in small electronic devices like watches and car key fobs.
Battery details:
- Type: CR2032 coin cell
- Voltage: 3 volts
- Lifespan: About 1 year
- Replaceable: Yes
- Rechargeable: No
When the battery runs low, your iPhone will notify you in the Find My app so you can replace it easily.
Why AirTags Are Not Rechargeable
Apple intentionally made AirTags non-rechargeable for several reasons:
- Compact size – The battery design allows for a small, sealed device that’s easy to carry or attach to items.
- Ease of maintenance – Instead of managing chargers, users simply replace the battery once a year.
- Durability – Without charging ports, the AirTag remains dust- and water-resistant (IP67 rated).
- Environmental efficiency – CR2032 batteries are recyclable and easy to replace without discarding the entire device.
How to Replace an AirTag Battery
Replacing the battery takes less than a minute and doesn’t require tools.
- Press and twist the stainless-steel back cover counterclockwise until it stops turning.
- Remove the cover and old battery.
- Insert a new CR2032 coin cell battery with the positive side (+) facing up.
- You’ll hear a sound confirming the new battery is connected.
- Reattach the cover and twist clockwise to lock it in place.
Your AirTag will reconnect automatically and resume tracking immediately.
Choosing the Right Replacement Battery
When buying replacement batteries, note the following:
- Use a standard CR2032 lithium coin cell battery.
- Avoid “bitterant-coated” batteries (like some Duracell models) – the coating can interfere with contact points and cause power issues.
- Choose reliable brands such as Energizer, Panasonic, or Sony for best performance.
A good-quality battery typically lasts around 12 months under normal use.
How to Check AirTag Battery Level
You can monitor the battery status directly from your iPhone:
- Open the Find My app.
- Tap the Items tab.
- Select your AirTag.
- The battery icon appears below the name of the AirTag if it’s running low.
When you see a low-battery warning, replace it soon to avoid disconnection.
Can You Modify or Recharge It Yourself?
Attempting to recharge or modify an AirTag’s battery is not recommended and can damage the device.
The CR2032 battery is not rechargeable and could leak, overheat, or explode if connected to power.
If you prefer a tracker with rechargeable batteries, consider alternatives such as:
- Tile Pro (2022+) – Rechargeable with USB-C
- Chipolo Card Spot (2024) – Rechargeable and Find My-compatible
- GPS trackers (like Jiobit or Tracki) – Offer recharging and longer battery life
Summary
