Let’s get started!

Why You Might Need to Change the Battery

Before we dive into the steps, it’s helpful to understand why you might need to replace your Eufy doorbell battery in the first place.

Most Eufy doorbells come with a built-in rechargeable lithium-ion battery. Depending on usage, motion detection settings, and environmental factors, the battery typically lasts between 3 to 6 months on a single charge. However, over time, rechargeable batteries lose their capacity. You might notice your doorbell dying faster, not holding a charge, or shutting off unexpectedly—even after a full charge.

Other signs it’s time for a battery replacement include:

  • The doorbell fails to turn on after charging.
  • The EufySecurity app shows a persistent low battery warning.
  • The device overheats during charging.
  • You’ve used the same battery for over 18–24 months.

Replacing the battery restores full performance and ensures your doorbell stays reliable. It’s a small maintenance task that makes a big difference in home security.

What You’ll Need

Before you begin, gather these items to make the process smooth and safe:

  • A replacement Eufy battery: Always use a genuine Eufy rechargeable battery compatible with your model. Third-party batteries may damage the device or void your warranty.
  • A micro-USB or USB-C charging cable: Depending on your model, you’ll need the correct cable to charge the battery.
  • A small Phillips-head screwdriver (optional): Some models require removing a security screw to access the battery.
  • A clean, dry workspace: Choose a flat surface with good lighting.
  • Your smartphone with the EufySecurity app installed: This helps monitor battery status and reconnect the device.

Having everything ready beforehand saves time and reduces the risk of losing small parts.

Step 1: Check Battery Level in the EufySecurity App

Before removing the battery, confirm that it’s actually time for a replacement. The EufySecurity app makes this easy.

Open the EufySecurity App

Launch the app on your smartphone. Make sure you’re logged into the account linked to your doorbell.

Select Your Doorbell

Tap on the device icon for your doorbell. This will open the live view and settings menu.

Check Battery Status

Look for the battery icon in the top-right corner of the screen. It will show a percentage (e.g., 15%) or a warning symbol if the battery is critically low.

If the battery is below 20%, it’s a good idea to replace or recharge it soon. If it’s consistently draining quickly, a replacement may be needed.

Note Any Error Messages

The app may display messages like “Low Battery” or “Charging Failed.” These can help diagnose whether the issue is with the battery, charger, or doorbell itself.

Once you’ve confirmed the battery needs replacing, proceed to the next step.

Step 2: Power Down the Doorbell

Safety first! Even though Eufy doorbells are battery-powered, it’s best to power them down before handling the battery.

Turn Off the Doorbell via the App

In the EufySecurity app, go to the device settings and look for an option like “Power Off” or “Restart.” Tap it to shut down the doorbell remotely.

Alternatively, you can remove the battery to power it off, but doing it through the app is cleaner and avoids accidental damage.

Wait 30 Seconds

Give the device time to fully power down. This ensures no residual charge remains in the system.

Unplug the Charger (If Connected)

If your doorbell is currently charging, unplug the USB cable from the power source and the doorbell.

Now the doorbell is safely powered off and ready for battery removal.

Step 3: Remove the Eufy Doorbell from the Mount

Most Eufy doorbells are designed to be easily detached from their wall mounts. Here’s how to do it safely.

Locate the Release Mechanism

Look at the bottom edge of the doorbell. You’ll see a small slot or button. This is the release tab.

Insert a Tool or Your Fingernail

Use a flathead screwdriver, a plastic prying tool, or your fingernail to gently press the release tab upward.

Lift the Doorbell Off the Mount

Once the tab is pressed, the doorbell will loosen. Carefully lift it straight up and away from the wall mount.

Be gentle—don’t force it. The doorbell is still connected to the mounting bracket by a short cable in some models, so don’t pull too hard.

Place It on a Stable Surface

Set the doorbell face-down on a soft cloth or towel to protect the lens and sensors.

Now you’re ready to access the battery compartment.

Step 4: Open the Battery Compartment

The battery is housed inside the doorbell’s main body. Accessing it varies slightly by model, but the process is similar.

Look for the Battery Cover

On most Eufy doorbells, the battery compartment is on the back or bottom of the device. It’s usually marked with a small battery icon.

Remove the Security Screw (If Present)

Some models, like the Eufy Video Doorbell 2K, have a small Phillips-head screw securing the battery cover. Use a screwdriver to remove it and set it aside in a safe place.

Slide or Lift the Cover

Once the screw is removed, gently slide or lift the cover away from the doorbell. It should come off easily.

Expose the Battery

You’ll now see the rechargeable battery inside. It’s typically a flat, rectangular lithium-ion pack with a connector attached.

Avoid touching the metal contacts on the battery or the doorbell’s internal components.

Step 5: Disconnect and Remove the Old Battery

Now it’s time to safely remove the old battery.

Locate the Battery Connector

Find the small plug that connects the battery to the doorbell’s circuit board. It’s usually a white or black connector with two wires.

Gently Unplug the Connector

Use your fingers or a plastic tool to carefully pull the connector straight out. Do not pull on the wires—grasp the plastic plug itself.

If it’s stuck, wiggle it slightly while pulling. Never use metal tools, as they can damage the connector.

Remove the Battery

Once disconnected, lift the battery out of its compartment. It should come out easily.

Inspect the Battery

Check for signs of damage: swelling, leakage, or corrosion. If you see any of these, handle the battery with extra care and dispose of it properly at an electronics recycling center.

Do not puncture or incinerate lithium-ion batteries.

Step 6: Install the New Battery

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

Insert the New Battery

Place the new Eufy battery into the compartment, aligning it with the slot. Make sure it sits flat and secure.

Reconnect the Battery Connector

Take the connector from the new battery and plug it into the corresponding port on the doorbell’s circuit board. Push it in firmly until it clicks.

Ensure the connection is secure—loose connections can cause power issues.

Replace the Battery Cover

Slide or snap the cover back into place. If your model has a security screw, reinsert and tighten it gently. Don’t overtighten, as this can strip the screw or crack the plastic.

Double-Check Everything

Make sure the battery is seated properly, the cover is closed, and all screws are in place.

Your doorbell is now ready for reassembly.

Step 7: Reattach the Doorbell to the Mount

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

Align the Doorbell with the Mount

Hold the doorbell so the mounting pins on the back align with the slots on the wall bracket.

Slide It Downward

Gently slide the doorbell down until it clicks into place. You should feel it lock securely.

Test the Fit

Give the doorbell a light tug to make sure it’s firmly attached. It shouldn’t wobble or come loose.

Ensure Weatherproofing

Check that the seal around the edges is intact. A properly mounted doorbell is protected from rain and dust.

Step 8: Charge the New Battery

Even if the new battery comes pre-charged, it’s best to give it a full charge before use.

Connect the Charging Cable

Plug the micro-USB or USB-C cable into the charging port on the doorbell. Connect the other end to a power source, such as a wall adapter or computer.

Wait for Full Charge

Charging typically takes 3 to 5 hours. The LED indicator on the doorbell will turn solid green when fully charged.

Monitor via the App

Open the EufySecurity app to check the battery level. It should show 100% once charging is complete.

Never use the doorbell while it’s charging unless absolutely necessary.

Step 9: Power On and Test the Doorbell

With the battery charged, it’s time to turn the doorbell back on.

Power On via the App

In the EufySecurity app, go to the device settings and tap “Power On” or “Restart.”

Alternatively, the doorbell may power on automatically once the battery is connected and charged.

Wait for Connection

Give the doorbell 1–2 minutes to reconnect to your Wi-Fi network. The LED should blink blue during setup, then turn solid when connected.

Test the Features

Press the doorbell button to trigger a notification on your phone. Check the live view, motion detection, and audio quality.

If everything works, your doorbell is back in action!
