How to Replace an AirTag Battery: A Step-by-Step Guide 🔋
AirTags are small tracking devices designed to be durable and long-lasting, but like any device with a battery, they eventually need a replacement. The good news: replacing an AirTag battery is straightforward and doesn't require special tools or technical skill. This guide walks you through the process so you can keep your AirTag working reliably.
What Battery Does an AirTag Use?
AirTags use a CR2032 coin cell battery, a common, inexpensive battery type you can find at most drugstores, supermarkets, and online retailers. This is the same type used in many watches, calculators, and medical devices. You don't need an Apple-specific battery—any CR2032 will work.
When to Replace Your AirTag Battery
Your iPhone or iPad will notify you when your AirTag's battery is running low. You may also notice the AirTag app shows a low-battery warning or the battery status changes color. The actual lifespan depends on how often the AirTag communicates, environmental conditions, and usage patterns—but most users find batteries last roughly a year or longer before needing replacement.
The Replacement Process: 5 Simple Steps
Step 1: Gather what you need
Locate a fresh CR2032 battery. You'll also benefit from having a flat, soft surface to work on (a cloth or towel helps prevent the small parts from rolling away). No special tools are required.
Step 2: Locate the battery compartment
Hold your AirTag with the stainless steel side facing up. At the bottom of the white plastic side, you'll see a small indented circle—this is the battery compartment cover.
Step 3: Open the compartment
Press down firmly on the indented circle and twist counterclockwise (to the left) about a quarter turn. The stainless steel ring should loosen and come free. Don't force it; gentle, steady pressure works best.
Step 4: Remove and replace the battery
Lift out the old battery carefully. The flat side of the CR2032 typically faces upward. Insert the new battery with the flat (+) side facing up and the raised side facing down. This orientation matters—if it's reversed, the AirTag won't work.
Step 5: Reseal the compartment
Place the stainless steel ring back into position and twist clockwise (to the right) until it's snug. It should feel secure but doesn't need to be forced. You'll hear or feel a gentle click when it's seated properly.
After Battery Replacement
Once sealed, your AirTag should reconnect automatically within moments. Check your iPhone or iPad to confirm the battery status has cleared and the AirTag appears as connected. If it doesn't show as connected right away, wait a few seconds and refresh your app—this is normal.
Key Points to Remember
| Element | Detail |
|---|---|
| Battery type | CR2032 coin cell (standard, widely available) |
| Orientation | Flat (+) side faces up |
| Tools needed | None—use your hands |
| Difficulty level | Very straightforward; no technical skill required |
A word of caution: CR2032 batteries contain lithium. Keep them away from children and pets, and store unused batteries safely. If a battery is swallowed, seek medical attention immediately.
The most common mistake people make is inserting the battery upside down. If your AirTag doesn't work after replacement, simply repeat steps 3–5 with the correct orientation.
If you're uncomfortable opening the battery compartment or encounter resistance, stop and consider having Apple Store staff handle it—they can do it quickly and safely. The choice depends on your comfort level with small mechanical tasks.
