AirTags are a handy way to keep track of your stuff. But like any battery-powered device, they eventually need a new battery. Luckily, replacing the AirTag’s battery is a breeze. With just a few simple steps, you can have your AirTag working like new again.
1. What You Need
- A New Battery: You need a CR2032 lithium 3V coin battery.
- The “Bitterant” Warning: This is the most important step. Many battery manufacturers (like Duracell) coat their coin batteries in a bitter-tasting substance to prevent children from swallowing them. Apple AirTags often do not work with bitterant-coated batteries because the coating can prevent the battery terminals from making a proper connection. Look for batteries labeled “Non-Bitterant” or wipe the battery down with an alcohol prep pad before installing.
2. Step-by-Step Instructions
Step 1: Open the AirTag
- Hold the AirTag with the polished silver stainless steel battery cover facing toward you.
- Press down firmly on the silver cover.
- While pressing down, rotate the cover counter-clockwise (to the left) until it stops rotating.
Step 2: Remove the Old Battery
- Lift off the silver cover.
- Remove the old battery and set it aside for recycling.
Step 3: Insert the New Battery
- Insert the new CR2032 battery with the positive (+) side facing up (you should see the text and the “+” sign on the battery).
- Press down on the battery. You should hear a distinct “chime” or startup sound. This sound indicates that the battery is connected and the AirTag is powered on. If you don’t hear a sound, the battery may have a bitterant coating that needs to be cleaned off.
Step 4: Close the AirTag
- Replace the silver cover, making sure the three tabs on the cover align with the three slots on the AirTag.
- Press down on the cover.
- Rotate the cover clockwise (to the right) until it stops and feels secure.
3. Troubleshooting
- No Sound: If you don’t hear the chime when pressing the battery down, the battery is likely upside down or has a coating blocking the connection. Ensure the “+” side is facing you.
- “Low Battery” Warning Won’t Go Away: Sometimes the Find My app takes a few hours to update the battery status. If it still says “Low Battery” after 24 hours, try removing and re-inserting the battery to “reboot” the tag.
- Cover Won’t Stay On: Ensure the three tabs are perfectly aligned with the slots before you start turning. If one tab is bent, the cover will sit crooked and won’t lock.
4. Safety & Disposal
- Choking Hazard: Coin batteries are extremely dangerous if swallowed. Keep both the old and new batteries away from children and pets at all times.
- Proper Disposal: Do not throw the old battery in the trash. Take it to a local electronics recycling center or a dedicated battery drop-off location (often found at Best Buy, Home Depot, or Lowe’s).
Pro Tip: If you are replacing multiple AirTag batteries at once, do them one at a time to avoid mixing up which AirTag belongs to which item in your Find My app!
