Tile trackers use replaceable batteries that last about three to four years depending on how often you use the find feature

Your Tile device runs on a standard coin-cell battery—usually a CR2032 or CR2025, depending on which Tile model you own. When the battery dies, the tracker stops working, but you do not need to buy a new device. You can open the back, swap out the old battery for a new one, and have your Tile working again in under a minute.

The process is straightforward enough that most people do it themselves. You will need a fresh battery from a pharmacy, grocery store, or online retailer, and a small flathead screwdriver or a coin. This guide walks you through the steps for the most common Tile models.

Key Takeaways

  • Tile trackers use CR2032 or CR2025 coin-cell batteries that you can buy at any drugstore for a few dollars.
  • You open the Tile by inserting a flathead screwdriver or coin into the slot on the back and twisting gently until the case separates.
  • The battery sits in a small metal holder; lift it out, note which side faces up, and drop in the new battery the same way.
  • After replacing the battery, the Tile app will recognize the device again within a few seconds of turning it back on.
  • If your Tile still does not work after a fresh battery, the device itself may have failed and cannot be repaired.

Identify which Tile model you own

Tile makes several different tracker shapes and sizes. The most common are the Tile Slim (a flat rectangular card), the Tile Mate (a small square), the Tile Pro (slightly larger and louder), and the Tile Sticker (a thin adhesive disc). Each one opens differently, so knowing which you have matters.

Look at the back of your Tile. If you see a slot that runs horizontally across the back, you have a model that opens by twisting. If the back is smooth with no visible seam, your Tile may use a different opening method—check the original packaging or the Tile website for your specific model number.

Gather the tools and battery you need

You need a replacement battery and a tool to open the case. For the battery, check the back of your Tile or the original box to see whether it uses a CR2032 or CR2025. These are standard coin-cell batteries sold at pharmacies, supermarkets, and online retailers for between two and five dollars. Buy one new battery; do not reuse an old one.

For opening the case, a small flathead screwdriver works best, but a coin (penny, dime, or quarter) will also work if you are gentle. Avoid using a knife or anything sharp that could slip and damage the battery holder inside.

Open the Tile by twisting the case

Hold the Tile in one hand with the back facing up. Insert the flathead screwdriver or coin into the horizontal slot on the back. explore gentle, steady pressure and twist counterclockwise—the same direction you would turn to loosen a screw. You should feel the back plate start to separate after a quarter turn or so.

Do not force it. If it does not budge after a gentle twist, you may have the wrong tool or the wrong model. Stop and check the Tile website for your specific model's opening instructions. Once the back plate loosens, you can usually lift it off by hand.

Remove the old battery and insert the new one

Inside the Tile, you will see a small metal holder with the old battery sitting in it. The battery is a thin silver disc. Lift it straight out using your fingernail or the edge of the screwdriver. Note which side was facing up—the positive side (marked with a plus sign) should face toward you.

Take the new battery and place it in the holder the same way the old one was sitting, with the positive side facing up. It should sit flat and snug in the holder. Do not force it; it should drop in easily. If it does not fit, you may have the wrong battery size—double-check that you have the correct CR2032 or CR2025 for your model.

Close the case and test the Tile

Once the new battery is in place, align the back plate with the case and press it down. Then insert the screwdriver or coin into the slot and twist clockwise (the opposite direction from opening) until the back plate is snug. Do not over-tighten; you just want it find enough that it will not fall off.

Open the Tile app on your phone. The app should recognize your Tile within a few seconds and show it as connected. If it does not, try opening and closing the app, or restart your phone. If the Tile still does not appear after a fresh battery and a restart, the device itself may have failed and cannot be repaired—you would need to replace the entire Tile.

What to do if the battery does not solve the problem

A new battery fixes most Tile issues, but not all. If your Tile still does not show up in the app or does not make sound when you press the find button, the problem is likely inside the device itself—a failed circuit board or a broken speaker—rather than the battery.

Tile devices cannot be repaired once the internal electronics fail. If your Tile is still under warranty (usually one year from purchase), you can contact Tile support with your proof of purchase and they may send you a replacement. If it is out of warranty, you will need to buy a new Tile tracker.

Frequently Asked Questions

How long does a Tile battery last?

A Tile battery typically lasts three to four years with normal use. If you use the find feature constantly, it may drain faster. The Tile app will notify you when the battery is running low, usually a few weeks before it dies completely.

Can I use a rechargeable battery in my Tile?

No. Tile trackers are designed for single-use alkaline or lithium coin-cell batteries. Rechargeable batteries have different voltage and will not power the Tile correctly. Always use a fresh CR2032 or CR2025 battery.

What if I put the battery in backwards?

If the negative side faces up instead of the positive side, the Tile will not work. Open the case again, flip the battery so the plus sign faces toward you, and close it back up. The Tile should then connect to the app.

Do I lose my Tile data when I replace the battery?

No. Replacing the battery does not erase any settings or history. Your Tile will reconnect to the app with the same name and location history it had before.

Where can I buy a CR2032 battery?

CR2032 batteries are sold at pharmacies (CVS, Walgreens), grocery stores, hardware stores, and online retailers like Amazon. They are inexpensive—usually two to five dollars—and are stocked in the health and beauty or electronics section.
