By the end of this guide, you’ll be confident in handling battery changes on your own, saving time and avoiding unnecessary service calls. Let’s get started!

Why Changing the Battery Matters

Your Eufy doorbell is more than just a camera—it’s your home’s first line of defense against intruders, package thieves, and unexpected visitors. A dead battery means no live view, no motion alerts, and no recorded footage. That’s why keeping your doorbell powered is essential for home security.

Most Eufy doorbells use removable rechargeable batteries, which means you don’t need to replace the entire unit when the battery wears out. Instead, you can simply swap in a fresh one and extend the life of your device. Regular battery maintenance also helps prevent unexpected outages and ensures your doorbell is always ready to capture important moments.

Additionally, proper battery handling protects both your device and your safety. Lithium-ion batteries, while reliable, can be hazardous if mishandled. Following the correct procedure minimizes risks like short circuits, overheating, or damage to the doorbell’s internal components.

What You’ll Need

Before you begin, gather the following tools and materials. Having everything ready will make the process faster and safer.

• Replacement battery: Make sure it’s compatible with your Eufy doorbell model. Check the model number (usually found on the back or in the app) and purchase a genuine Eufy battery or a high-quality third-party alternative.
• Small Phillips-head screwdriver: Used to remove the mounting plate or access panel, depending on your model.
• Eufy release key or paperclip: Most Eufy doorbells come with a small metal key designed to unlock the battery compartment. If you’ve misplaced it, a straightened paperclip works in a pinch.
• Soft cloth or microfiber towel: To clean the doorbell and prevent scratches during handling.
• Ladder (if needed): If your doorbell is mounted high, use a stable ladder to reach it safely.
• Gloves (optional): To protect your hands and keep the device clean.

Pro tip: Always buy batteries from reputable sources. Cheap knockoffs may not meet safety standards and could damage your doorbell or pose a fire risk.

Step 1: Turn Off Power and Prepare the Area

Safety first! Even though Eufy doorbells are battery-powered, some models can also be hardwired. If yours is connected to your home’s electrical system, you must turn off the power before removing the device.

Check Your Doorbell’s Power Source

Most Eufy doorbells operate on battery power alone, but some models support dual power (battery + wired). To check:

• Open the EufySecurity app on your phone.
• Go to Devices and select your doorbell.
• Look for a “Power Source” or “Power Mode” setting. If it says “Wired + Battery,” you’ll need to shut off the power.

Turn Off the Circuit Breaker

If your doorbell is hardwired:

1. Locate your home’s main electrical panel (breaker box).
2. Find the circuit that controls your doorbell—this is usually labeled “Doorbell,” “Front Door,” or something similar.
3. Switch the breaker to the “OFF” position.
4. Test the doorbell by pressing the button. If it doesn’t ring or light up, the power is off.

Even if your doorbell is battery-only, it’s a good habit to double-check that no wires are live before handling the device.

Clear the Work Area

Make sure the area around your doorbell is clean and free of obstacles. Remove any decorations, plants, or furniture that might interfere. If you’re using a ladder, place it on a flat, stable surface and have someone hold it if possible.

Wear gloves if you’re concerned about fingerprints or oils transferring to the doorbell’s lens or sensors.

Step 2: Remove the Eufy Doorbell from the Mount

Now that the power is off and the area is clear, it’s time to take the doorbell off the wall.

Locate the Release Mechanism

Eufy doorbells are designed with a secure mounting system to prevent theft. To remove the device, you’ll need to unlock it using the release key or paperclip.

• Look for a small hole on the bottom or side of the doorbell—this is the release slot.
• Insert the Eufy release key (or straightened paperclip) into the hole and press firmly.
• You should feel a slight click as the locking mechanism disengages.

Gently Pull the Doorbell Away

Once unlocked, carefully pull the doorbell straight away from the wall. It should come off easily, but don’t force it. If it feels stuck, double-check that the release mechanism is fully engaged.

Hold the doorbell with both hands to avoid dropping it. Place it on a soft surface, like a towel, to protect the lens and casing.

Disconnect Wires (If Applicable)

If your doorbell is hardwired, you’ll see two small wires connected to the back. These are low-voltage wires, but they should still be disconnected safely.

• Use your fingers or a small screwdriver to gently loosen the terminal screws.
• Carefully pull the wires free. Don’t pull on the wires themselves—grip the connectors.
• Label the wires (e.g., “Front” and “Trans”) with tape if you’re unsure which is which. This will help during reinstallation.

Set the doorbell aside in a safe place while you work on the battery.

Step 3: Access the Battery Compartment

With the doorbell removed, you can now access the battery. The process varies slightly depending on your Eufy model, but the general steps are the same.

Identify the Battery Cover

Most Eufy doorbells have a removable back panel or a sliding battery tray. Look for a small latch, screw, or release tab on the back or bottom of the device.

• On models like the Eufy Video Doorbell 2K, the battery is accessed by removing two small screws on the back.
• On newer models like the Eufy Doorbell Dual, the battery tray slides out from the bottom after pressing a release button.

Remove the Cover or Tray

Use your Phillips-head screwdriver to remove any screws securing the battery cover. Keep the screws in a small container so you don’t lose them.

If your model uses a sliding tray:

• Press the release button (usually marked with an arrow).
• Slide the tray out gently. It should move smoothly—don’t force it.

Once the cover or tray is removed, you’ll see the lithium-ion battery inside. It’s typically a flat, rectangular pack with a connector attached.

Step 4: Remove the Old Battery

Now it’s time to take out the old battery. Handle it carefully to avoid damage or injury.

Disconnect the Battery Connector

The battery is connected to the doorbell’s internal circuitry via a small plug. To remove it:

• Gently pull the connector straight out. Do not yank or twist it.
• If it’s tight, use a plastic spudger or your fingernails to wiggle it loose.
• Never use metal tools to pry the connector—this can damage the pins.

Lift Out the Battery

Once disconnected, lift the battery out of the compartment. It should come out easily. If it’s stuck, check for any adhesive or clips holding it in place.

Inspect the battery for signs of damage:

• Swelling or bulging
• Leaking fluid
• Burn marks or discoloration

If you notice any of these, do not reuse the battery. Handle it as hazardous waste and dispose of it properly.

Clean the Compartment (Optional)

Use a dry cloth or compressed air to remove dust or debris from the battery compartment. This helps ensure a clean connection for the new battery.

Step 5: Install the New Battery

With the old battery removed, it’s time to install the replacement.

Check Compatibility

Before inserting the new battery, double-check that it’s the correct model. The voltage, size, and connector type must match your doorbell’s specifications. Using the wrong battery can damage the device or void the warranty.

Connect the New Battery

Align the connector on the new battery with the port inside the doorbell. Push it in gently until it clicks into place. Make sure it’s fully seated—loose connections can cause power issues.

Insert the Battery

Place the battery into the compartment, ensuring it fits snugly. If your model uses a tray, slide it back in until it locks. If it uses a cover, reattach it and secure it with screws.

Tighten the screws evenly to avoid cracking the plastic. Don’t over-tighten—just snug is enough.

Step 6: Reattach the Doorbell

With the new battery installed, it’s time to put the doorbell back on the wall.

Reconnect Wires (If Applicable)

If your doorbell is hardwired, reconnect the two wires to the terminals on the back. It doesn’t matter which wire goes where—Eufy doorbells are not polarity-sensitive. Just make sure both are secure.

Mount the Doorbell

Align the doorbell with the mounting plate on the wall. Slide it into place until it clicks and locks.

Test the lock by gently tugging on the doorbell. It should stay firmly in place.

Turn Power Back On

If you turned off the circuit breaker, switch it back to “ON.” Wait a few seconds for the doorbell to power up.

Step 7: Test the Doorbell

Now that everything is reassembled, it’s time to make sure it works.

Check Power and Connectivity

Open the EufySecurity app and go to your doorbell’s live view. You should see a clear video feed within a few seconds.

If the app shows “Offline” or “No Signal,” try the following:

• Press the doorbell button to wake it up.
• Check your Wi-Fi signal strength at the doorbell’s location.
• Restart your router and the doorbell.

Test the Battery Level

In the app, go to Device Settings > Battery. The battery level should show as “Full” or close to 100%. If it’s low, the new battery may need a full charge.

Verify Motion and Alerts

Walk in front of the doorbell to test motion detection. You should receive a notification on your phone. Also, press the button to ensure the chime or notification works.

Troubleshooting Common Issues

Even with careful installation, you might run into problems. Here’s how to fix the most common ones.
