Why Replace the Battery in Your Eufy Tracker?

Before diving into the how-to, it’s important to understand why battery replacement matters. Eufy trackers are designed to be compact, lightweight, and long-lasting, but like all electronic devices, their batteries eventually wear out. Over time, the lithium coin cell battery (usually a CR2032) loses its charge capacity, leading to shorter tracking range, delayed alerts, or complete failure to connect.

Common signs that your Eufy tracker needs a new battery include:

• The tracker no longer appears in the Eufy Security app
• You receive repeated “low battery” notifications
• The device takes longer than usual to respond when located
• The LED indicator (if present) flashes red or doesn’t light up

Replacing the battery promptly ensures your tracker continues to protect your keys, wallet, luggage, or other valuables. It’s a small maintenance task that makes a big difference in reliability.

What You’ll Need

Before you begin, gather the following tools and materials. Having everything ready will make the process smoother and reduce the risk of losing small parts.

Essential Tools

• Small Phillips-head screwdriver (size #0 or #1): Most Eufy trackers use tiny screws that require precision.
• Plastic prying tool or guitar pick: This helps open the casing without scratching or damaging the plastic.
• Tweezers (optional but helpful): Useful for handling small screws or the battery itself.
• Clean, well-lit workspace: A flat surface with good lighting prevents lost parts and improves visibility.

Replacement Battery

• CR2032 3V lithium coin cell battery: This is the standard battery used in most Eufy trackers. Always check your model’s manual to confirm.
• Genuine or high-quality compatible battery: Avoid cheap knockoffs. Brands like Panasonic, Energizer, or Duracell are reliable choices.

Optional but Recommended

• Magnifying glass (for better visibility of small components)
• Small container or magnetic tray (to hold screws)
• Isopropyl alcohol and cotton swab (for cleaning contacts, if needed)

Step-by-Step Guide: How to Change Battery in Eufy Tracker

Now that you’re prepared, let’s walk through the battery replacement process. We’ll use the Eufy SmartTrack Card as our primary example, but the steps are similar for most Eufy tracker models.

Step 1: Power Off the Tracker

Before touching any internal components, make sure your Eufy tracker is completely powered off. While these devices don’t have a traditional “off” switch, you can disable them through the Eufy Security app.

• Open the Eufy Security app on your smartphone.
• Navigate to the “Devices” tab and select your tracker.
• Tap “Settings” and look for an option like “Disable Device” or “Turn Off.”
• Confirm the action. This prevents accidental signals or data corruption during the battery swap.

Pro Tip: Even though the tracker may still have some charge, turning it off in the app ensures it won’t try to connect or send alerts while you’re working on it.

Step 2: Locate the Screws on the Tracker

Most Eufy trackers have a two-piece plastic shell held together by small screws. These are usually hidden under the device’s label or on the edges.

• Turn the tracker over and inspect the back or sides for tiny screw heads.
• On the SmartTrack Card, there are typically two screws near the corners.
• Use a magnifying glass if needed—some screws are very small and hard to see.

Note: Some newer models may use snap-fit designs instead of screws. If you don’t see screws, gently try prying the case open with a plastic tool. Avoid using metal, as it can scratch or crack the plastic.

Step 3: Remove the Screws

Using your Phillips-head screwdriver, carefully unscrew each fastener.

• Hold the screwdriver steady and apply gentle downward pressure to prevent slipping.
• Place each screw in a small container or magnetic tray as you remove it. Losing even one screw can make reassembly difficult.
• If a screw feels stuck, don’t force it. Apply a tiny drop of isopropyl alcohol around the edge to loosen any residue.

Safety Reminder: Never use excessive force. Eufy trackers are designed to be user-serviceable, but rough handling can damage internal circuits.

Step 4: Open the Tracker Casing

Once the screws are removed, it’s time to separate the two halves of the tracker.

• Insert the plastic prying tool into the seam between the front and back covers.
• Gently twist the tool to create a small gap. Work your way around the edges slowly.
• Avoid prying near the antenna or circuit board areas—these are more fragile.

Pro Tip: If the case doesn’t open easily, double-check that all screws are removed. Some models have hidden screws under stickers or rubber pads.

Step 5: Locate the Battery

With the casing open, you’ll see the internal components. The battery is usually a small, round, silver disc seated in a plastic holder.

• The CR2032 battery is typically held in place by a metal clip or spring contact.
• Note the orientation of the battery: the positive (+) side usually faces up, with the negative (–) side down.
• Take a photo with your phone before removing the battery—this helps you remember the correct position.

Important: Never touch both sides of the battery with metal tools at the same time. This can cause a short circuit.

Step 6: Remove the Old Battery

Carefully extract the old battery from its housing.

• Use your fingernail or a plastic tool to gently lift one edge of the battery.
• If it’s held by a clip, gently press the clip aside to release the battery.
• Avoid using metal tweezers directly on the battery terminals to prevent damage.

Disposal Tip: Place the old battery in a small plastic bag or container. Do not throw it in regular trash. Lithium batteries should be recycled at a certified e-waste center or battery drop-off location.

Step 7: Insert the New Battery

Now it’s time to install the fresh CR2032 battery.

• Ensure the positive (+) side is facing up, matching the orientation of the old battery.
• Press the battery firmly into the holder until it sits flat and secure.
• If there’s a clip, make sure it snaps back into place over the battery.

Double-Check: A misaligned battery can prevent the tracker from powering on. If in doubt, refer to your photo or the markings inside the battery compartment.

Step 8: Reassemble the Tracker

With the new battery in place, it’s time to put the tracker back together.

• Align the two halves of the casing carefully. Make sure no wires or components are pinched.
• Press the edges together until you hear a soft click or feel the pieces snap into place.
• Reinsert the screws and tighten them gently. Do not overtighten—this can strip the screw holes or crack the plastic.

Pro Tip: If the case doesn’t close completely, check that the battery is seated properly and no internal parts are out of place.

Step 9: Power On and Test the Tracker

Now that your Eufy tracker is reassembled, it’s time to test it.

• Open the Eufy Security app and go to the Devices section.
• Enable the tracker if you turned it off earlier.
• Wait a few seconds for the device to reconnect to your phone via Bluetooth.
• Test the tracking function by using the “Find Device” feature in the app.

If the tracker responds quickly and shows a full or high battery level, congratulations—you’ve successfully changed the battery!

Troubleshooting Common Issues

Even with careful handling, you might run into a few hiccups. Here’s how to solve the most common problems.

Tracker Won’t Turn On After Battery Replacement

• Check battery orientation: The most common cause is installing the battery upside down. Open the case and verify the + and – sides.
• Ensure full contact: The battery must sit flat in its holder. If it’s loose, the device won’t power on.
• Try a different battery: Sometimes new batteries are defective. Test with another CR2032 if available.

App Doesn’t Recognize the Tracker

• Restart the app and your phone: Bluetooth connections can glitch. A quick reboot often fixes it.
• Re-pair the device: Go to the app settings and remove the tracker, then add it again as a new device.
• Check Bluetooth range: Make sure your phone is within 10–30 feet of the tracker.

LED Light Doesn’t Flash

• Wait a moment: Some trackers take 10–15 seconds to initialize after a battery change.
• Press the button (if available): On models with a physical button, press it to trigger the LED.
• Inspect for damage: If the LED still doesn’t work, the bulb or circuit may be damaged. Contact Eufy support.

Case Won’t Close Properly

• Check for obstructions: Make sure no wires, clips, or the battery itself are sticking out.
• Realign the halves: Sometimes the casing shifts during disassembly. Adjust and try again.
• Don’t force it: Forcing the case can crack the plastic. If it doesn’t close easily, reopen and inspect.
