Apple AirTag is a popular tracking device that helps users locate lost items using the Find My app. One of its key advantages is its replaceable battery, which provides long-lasting performance without needing frequent recharging. Understanding the battery type used in an AirTag, how to replace it, and ways to maximize battery life can help users get the most out of their device.
This guide explains the type of battery used in Apple AirTags, how to replace it, how long it lasts, and tips for maintaining optimal performance.
What Type of Battery Does Apple AirTag Use?
Apple AirTag uses a CR2032 lithium coin cell battery, a small, round, disposable battery commonly found in watches, calculators, and small electronic devices. The CR2032 battery is widely available and can be purchased at electronics stores, supermarkets, and online retailers.
CR2032 Battery Specifications
- Battery type: Lithium coin cell
- Voltage: 3 voltages
- Diameter: 20mm
- Thickness: 3.2mm
- Typical lifespan: Around one year in an AirTag
How Long Does an Apple AirTag Battery Last?
Apple states that an AirTag battery lasts approximately one year under normal usage. The actual lifespan depends on usage factors such as the frequency of sound alerts, the number of location pings, and environmental conditions.
Frequent use of the Precision Finding feature or playing sound alerts often may cause the battery to drain faster.
How to Check AirTag Battery Life
Unlike other Apple devices, AirTags do not display a precise battery percentage. However, users can check the battery status in the Find My app.
Steps to Check AirTag Battery Status
- Open the Find My app on an iPhone.
- Tap the Items tab at the bottom of the screen.
- Select the AirTag whose battery status you want to check.
- The battery indicator will appear below the AirTag’s name.
If the battery is low, a notification will appear in the Find My app, reminding users to replace it soon.
How to Replace an Apple AirTag Battery
Replacing the battery in an AirTag is simple and requires no tools.
Steps to Replace the AirTag Battery
- Hold the AirTag with the Apple logo facing up.
- Press down on the stainless steel cover and rotate it counterclockwise.
- Remove the cover and take out the old battery.
- Insert a new CR2032 battery with the positive (+) side facing up.
- Place the cover back and rotate it clockwise until it locks into place.
Once the new battery is inserted, the AirTag will play a sound to confirm that it has been successfully powered on.
Best CR2032 Batteries for Apple AirTags
Many brands manufacture CR2032 batteries, but not all work well with AirTags. Some CR2032 batteries come with a bitterant coating to prevent accidental ingestion, which may interfere with the AirTag’s battery contact points.
Recommended CR2032 Battery Brands for AirTags
- Duracell CR2032: Avoid the bitterant-coated version, as it may not work properly with AirTags.
- Energizer CR2032: compatible and widely available.
- Panasonic CR2032: long-lasting and reliable.
- Sony CR2032: Known for consistent performance.
If a new battery does not work, checking for a bitterant coating or trying a different brand may help resolve the issue.
How to Maximize Apple AirTag Battery Life
Although AirTag batteries last about a year, following some simple steps can help extend battery life.
Avoid Excessive Sound Alerts
Playing sound alerts frequently drains the battery faster. Using sound only when necessary helps conserve power.
Use Precision Finding Sparingly
The Precision Finding feature, available on iPhones with U1 chips, requires extra power. Limiting its use can help extend battery life.
Keep the AirTag in a Stable Environment
Extreme temperatures can affect battery life. Keeping the AirTag in normal conditions helps maintain battery performance.
Check Battery Levels Regularly
Monitoring the battery status in the Find My app ensures the battery is replaced before it runs out.
What Happens When an AirTag Battery Dies?
If an AirTag battery runs out, the AirTag will stop functioning, meaning:
- It will no longer update its location in the Find My app.
- Precision Finding and sound alerts will not work.
- The AirTag will need a new battery to function again.
Replacing the battery restores full functionality immediately.
Does AirTag Have a Rechargeable Battery?
No, AirTags do not have a rechargeable battery. Apple designed them with a replaceable CR2032 battery to ensure convenience and cost-effectiveness.
Environmental Considerations for AirTag Batteries
Since AirTags use disposable batteries, responsible disposal is important. CR2032 batteries should not be thrown in regular trash. Instead, they should be recycled at designated battery disposal centers or electronic stores that accept used batteries.
Future Possibilities for AirTag Battery Design
Apple may explore alternative battery solutions in future AirTag models. Possible improvements could include:
- Rechargeable battery options are similar to AirPods.
- Solar or kinetic energy solutions to extend battery life.
- More efficient power management to reduce energy consumption.
