Let’s get started!

Why Battery Replacement Matters

Eufy trackers are designed to help you keep tabs on your most important items—keys, wallets, backpacks, pets, and even kids. They use Bluetooth to connect to your smartphone via the EufySecurity app, sending alerts when you’re out of range and helping you locate lost items with precision. But like all electronic devices, they rely on a power source: a small coin cell battery.

Over time, that battery loses its charge. Depending on usage, a Eufy tracker battery can last anywhere from 6 to 12 months. When the battery runs low, you might notice:
– Delayed alerts when your item goes out of range
– The tracker not appearing in the app
– A “low battery” notification in the EufySecurity app
– Reduced Bluetooth range

Replacing the battery promptly ensures your tracker stays reliable. A fresh battery restores full functionality, improves connection strength, and gives you peace of mind knowing your belongings are protected.

What You’ll Need

Before you begin, gather the following tools and materials. Having everything ready will make the process faster and reduce the risk of damaging your device.

• A compatible replacement battery: Most Eufy trackers use a CR2032 3V lithium coin cell battery. Check your user manual or the label inside the battery compartment to confirm.
• A small Phillips or flathead screwdriver: Needed to remove screws on models like the SmartTrack Tag.
• A plastic prying tool or guitar pick: Helps gently open the casing without scratching or cracking it.
• A clean, well-lit workspace: A flat surface with good lighting prevents you from dropping small parts.
• Tweezers (optional): Useful for handling tiny screws or the battery itself.
• Soft cloth or microfiber towel: Protects the tracker’s surface during disassembly.

Tip: Avoid using metal tools near the battery or circuit board to prevent short circuits. If you don’t have a plastic prying tool, a credit card or old gift card works in a pinch.

Step 1: Identify Your Eufy Tracker Model

Not all Eufy trackers are built the same. The battery replacement process varies slightly depending on the model. Here’s how to identify which one you have:

Eufy SmartTrack Card

This slim, credit-card-sized tracker is designed to fit in wallets or card holders. It has no visible screws and is opened by prying apart the two halves of the casing. The battery is located in the center.

Eufy SmartTrack Tag

Resembling a small key fob, this model has a rectangular shape with a keyring hole. It’s held together with small screws on the back. You’ll need a screwdriver to open it.

Eufy SmartTrack Link

This compact, circular tracker is often attached to keys or bags. Like the SmartTrack Card, it has no screws and is opened by separating the two halves with a prying tool.

Check the back of your tracker or the original packaging for the model name. If you’re unsure, open the EufySecurity app, go to “Devices,” and select your tracker—it will display the model number.

Step 2: Power Down the Tracker (If Possible)

While most Eufy trackers don’t have an on/off switch, it’s a good idea to minimize activity during battery replacement. If your tracker has a button (like the SmartTrack Tag), press and hold it for 5 seconds to ensure it’s not actively transmitting.

This step isn’t always necessary, but it reduces the chance of interference or accidental resets during the process.

Step 3: Open the Tracker Casing

Now it’s time to access the battery. The method depends on your model.

For the SmartTrack Card or SmartTrack Link (No Screws)

These models use a snap-fit design. Follow these steps:

1. Place the tracker on a soft cloth to protect the surface.
2. Locate the seam where the two halves meet. It’s usually along the edge.
3. Insert a plastic prying tool or guitar pick into the seam. Start at one corner and gently twist to create a small gap.
4. Work your way around the edge, slowly prying the two halves apart. Be patient—forcing it can crack the plastic.
5. Once the top half lifts, carefully remove it to reveal the battery compartment.

Tip: If the casing feels stuck, try warming it slightly with a hairdryer on low heat for 10–15 seconds. This softens the plastic and makes it easier to open.

For the SmartTrack Tag (With Screws)

This model requires a bit more precision:

1. Place the tracker face down on a soft surface.
2. Use a small Phillips screwdriver to remove the two screws on the back. Set them aside in a small bowl so they don’t get lost.
3. Gently lift the back cover. You may need to wiggle it slightly to release any clips.
4. Once open, you’ll see the battery seated in a small compartment.

Caution: Don’t overtighten the screws when reassembling. This can strip the threads or crack the plastic.

Step 4: Remove the Old Battery

With the casing open, you’ll see the battery nestled in a small holder. Here’s how to remove it safely:

• Use a plastic tool or your fingernail to gently pry the battery out. Avoid using metal tweezers directly on the battery terminals.
• If the battery is held in place by a small metal clip, carefully lift the clip to release the battery.
• Note the orientation of the battery—most CR2032 batteries have the positive (+) side facing up. Take a quick photo with your phone for reference.

Important: Never puncture, crush, or expose the battery to heat. Damaged batteries can leak or catch fire.

Step 5: Insert the New Battery

Now it’s time to install the fresh battery:

1. Take your new CR2032 battery and confirm the positive (+) side is facing up (unless your model specifies otherwise).
2. Align the battery with the compartment and press it gently into place. It should sit flush with the housing.
3. If there’s a metal clip, make sure it securely holds the battery in place.
4. Double-check the orientation—incorrect installation can prevent the tracker from working.

Tip: Buy high-quality batteries from reputable brands like Duracell, Energizer, or Amazon Basics. Cheap knockoffs may not last as long or deliver consistent power.

Step 6: Reassemble the Tracker

With the new battery installed, it’s time to put your tracker back together.

For Snap-Fit Models (SmartTrack Card, SmartTrack Link)

Align the two halves carefully and press them together along the edges. You should hear a soft click as the clips engage. Make sure there are no gaps—this ensures a tight seal against dust and moisture.

For Screw-On Models (SmartTrack Tag)

Place the back cover over the tracker and align the screw holes. Insert the screws and tighten them gently with your screwdriver. Don’t force them—snug is enough.

After reassembly, wipe the tracker with a dry cloth to remove fingerprints or dust.

Step 7: Test the Tracker

The final step is to make sure everything is working correctly.

1. Open the EufySecurity app on your smartphone.
2. Go to “Devices” and select your tracker.
3. Check the battery level—it should now show as full or high.
4. Test the connection by walking a short distance away. You should receive a “device out of range” alert.
5. Use the “Find Device” feature to trigger a sound from the tracker (if supported).

If the tracker responds normally, congratulations—you’ve successfully changed the battery!

Troubleshooting Common Issues

Sometimes, things don’t go as planned. Here’s how to fix common problems:

Tracker Not Powering On

Double-check the battery orientation. If it’s correct, try reseating the battery. If it still doesn’t work, test the new battery with a multimeter or try a different one.

App Shows “Low Battery” After Replacement

This could mean the battery isn’t making proper contact. Open the tracker again and ensure the battery is seated correctly. Also, make sure the metal contacts inside are clean and not corroded.

Tracker Won’t Reconnect to the App

Try restarting your phone and the EufySecurity app. If that doesn’t work, reset the tracker by holding the button (if available) for 10 seconds. Then re-pair it in the app.

Casing Won’t Close Properly

Check for debris or misaligned parts. Make sure the battery isn’t protruding. If the clips are damaged, contact Eufy support for a replacement.

Battery Safety and Disposal

Used batteries contain chemicals that can harm the environment if thrown in the trash. Always recycle them responsibly.

• Take old batteries to a local recycling center, hardware store (like Home Depot or Lowe’s), or battery drop-off location.
• Some retailers offer mail-in recycling programs.
• Never incinerate or puncture batteries.

For CR2032 batteries, look for recycling programs that accept lithium coin cells. Many cities also host periodic e-waste collection events.

Tips to Extend Battery Life

A fresh battery is great, but you can make it last even longer with these tips:

• Avoid extreme temperatures: Don’t leave your tracker in a hot car or freezing conditions. Heat and cold reduce battery efficiency.
• Keep firmware updated: Eufy regularly releases updates that improve power management. Check the app monthly.
• Use “Smart Alerts” wisely: Frequent notifications drain the battery. Customize alert settings to only trigger when necessary.
• Store properly when not in use: If you won’t use the tracker for weeks, consider removing the battery to prevent slow discharge.

When to Contact Eufy Support

Most battery replacements go smoothly, but if you encounter persistent issues—like the tracker not holding a charge, physical damage, or water exposure—it’s time to reach out to Eufy.

Visit the official Eufy support website or use the in-app help feature. Provide your model number, purchase date, and a description of the problem. Many issues can be resolved with a firmware update or replacement part.
