Eufy doorbells are designed for convenience and reliability. Most models use rechargeable lithium-ion batteries that last 3–6 months on a single charge, depending on usage, climate, and settings like motion detection sensitivity. Over time, these batteries lose their ability to hold a charge. You might notice:
– The doorbell won’t turn on
– Frequent disconnections from Wi-Fi
– A blinking red light indicating low battery
– The app showing “Low Battery” or “Charging Required”
When these signs appear, it’s time to either recharge or replace the battery. If your doorbell has been in use for over a year and the battery drains quickly even after a full charge, replacement is likely needed. Continuing to use a degraded battery can damage the device or reduce video quality.
What You’ll Need Before Starting
Before you begin, gather these tools and materials:
- A small Phillips-head screwdriver (size #0 or #1)
- A non-conductive pry tool or plastic spudger (to avoid scratching)
- A replacement Eufy-compatible rechargeable battery (check your model for exact specs)
- A clean, dry workspace
- Optional: A microfiber cloth for cleaning
- Optional: A multimeter (to test old battery voltage)
Always purchase batteries from Eufy or authorized retailers to ensure compatibility and safety. Using third-party batteries may void your warranty or cause damage.
Step 1: Identify Your Eufy Doorbell Model
Not all Eufy doorbells use the same battery or removal method. Before proceeding, confirm your model. Common battery-powered models include:
– Eufy Video Doorbell 2K (Battery)
– Eufy Solo (Battery)
– Eufy Video Doorbell (2nd Gen Battery)
– Eufy Video Doorbell (Wired + Battery Backup)
Check the back of your device or the original packaging. You can also open the Eufy Security app, go to Device Settings, and view your doorbell’s model number.
Knowing your model ensures you get the correct replacement battery and follow the right steps. For example, the Eufy Solo uses a removable battery pack, while some 2K models have a built-in battery that requires more careful handling.
Step 2: Turn Off Power and Prepare the Area
Safety first! Even though your Eufy doorbell is battery-powered, some models are also wired to your home’s electrical system. To avoid any risk of shock:
Turn Off the Circuit Breaker
Locate your home’s electrical panel and turn off the breaker that controls your doorbell circuit. If you’re unsure which one it is, turn off the main breaker temporarily.
Test the Power
Use a non-contact voltage tester near the doorbell wires to confirm no electricity is flowing. This step is crucial if your doorbell is hardwired.
Clear the Work Area
Set up a clean, well-lit space with your tools nearby. Lay down a soft cloth to protect the doorbell and prevent screws from rolling away.
Step 3: Remove the Eufy Doorbell from the Wall
Now it’s time to take the doorbell off the mounting bracket.
Locate the Release Mechanism
Most Eufy battery doorbells have a small release tab or screw on the bottom. Look for a tiny hole or a recessed button.
Use the Screwdriver or Pry Tool
Insert the tip of your Phillips screwdriver or pry tool into the release hole. Gently press upward or sideways (depending on the model) to disengage the locking mechanism.
Lift the Doorbell Off
Once the lock is released, carefully lift the doorbell straight up and away from the mounting bracket. Support it with your other hand to avoid dropping it.
Disconnect Wires (If Applicable)
If your doorbell is wired, you’ll see two thin wires connected to the back. Gently pull the wire connectors apart. Do not pull on the wires themselves—grasp the plastic connectors.
Step 4: Open the Battery Compartment
With the doorbell removed, locate the battery compartment.
Find the Battery Cover
On most Eufy models, the battery is housed behind a removable faceplate or a sealed compartment on the back. The faceplate is usually held in place by two small screws.
Unscrew the Faceplate
Use your Phillips screwdriver to remove the screws. Keep them in a small container so you don’t lose them.
Gently Pry Open the Cover
Once the screws are out, use your pry tool to carefully separate the faceplate from the main body. Work slowly around the edges to avoid cracking the plastic.
Locate the Battery
You’ll now see the rechargeable lithium-ion battery pack. It’s typically rectangular and connected via a small plug.
Step 5: Remove the Old Battery
Now that the battery is exposed, it’s time to remove it.
Disconnect the Battery Plug
Gently unplug the battery connector from the circuit board. Use your fingers or a plastic tool—never metal, which can cause a short.
Lift Out the Battery
Carefully lift the battery out of its compartment. Note its orientation so you can install the new one the same way.
Inspect the Old Battery
Check for swelling, leaks, or corrosion. If the battery is puffed up or leaking, handle it with care and dispose of it properly at an e-waste facility.
Step 6: Install the New Battery
With the old battery removed, install the new one.
Insert the New Battery
Place the new battery into the compartment, matching the orientation of the old one. Ensure it sits flat and secure.
Reconnect the Plug
Plug the battery connector back into the circuit board. Push it in firmly until it clicks or feels snug.
Test the Connection (Optional)
If you have a multimeter, check the voltage to confirm the new battery is functional. Most Eufy batteries output around 3.7V when fully charged.
Step 7: Reassemble the Doorbell
Now it’s time to put everything back together.
Replace the Faceplate
Align the faceplate with the main body and press it into place. Make sure all edges are flush.
Screw It Back On
Reinsert the two screws and tighten them gently. Don’t over-tighten, as this can crack the plastic.
Check for Gaps
Ensure there are no gaps between the faceplate and the body. A tight seal protects the internal components from moisture.
Step 8: Reattach the Doorbell to the Wall
With the new battery installed, mount the doorbell back on the wall.
Reconnect Wires (If Wired)
If your doorbell is hardwired, reconnect the two wire connectors. Push them together until they click.
Align with Mounting Bracket
Position the doorbell over the mounting bracket and slide it down until it locks into place. You should hear a soft click.
Secure with Screw (If Applicable)
Some models have a security screw at the bottom. Insert and tighten it to prevent theft.
Step 9: Restore Power and Test the System
Now that everything is reassembled, it’s time to test.
Turn the Breaker Back On
Go to your electrical panel and restore power to the doorbell circuit.
Wait for the Doorbell to Boot
The doorbell will take 30–60 seconds to power on. You’ll see lights or hear a chime.
Open the Eufy Security App
Launch the app on your phone and check the device status. Look for:
– Battery level (should show charging or full)
– Wi-Fi connection
– Live video feed
– Motion detection alerts
Test the Doorbell
Press the doorbell button to ensure it rings and sends a notification to your phone. Walk in front of it to test motion detection.
Troubleshooting Common Issues
Even with careful installation, you might run into problems. Here’s how to fix them:
Doorbell Won’t Turn On

- Clean the lens and sensors: Wipe the camera and motion sensor monthly with a dry cloth.
- Update firmware regularly: Check the Eufy app for updates that improve battery efficiency.
- Use scheduled modes: Set the doorbell to “Home” or “Away” modes to reduce activity when not needed.
When to Replace vs. Recharge
Not every low battery means you need a new one. Here’s how to decide:
– Recharge if: The battery holds a charge for several months and only drains after heavy use.
– Replace if: The battery swells, leaks, or loses charge within days—even after a full charge.
Most Eufy batteries last 12–18 months with regular use. Keep a spare on hand so you’re never left without a working doorbell.
Safety and Environmental Considerations
Lithium-ion batteries require careful handling:
– Never puncture, crush, or expose to fire.
– Do not disassemble the battery pack.
– Recycle old batteries at certified e-waste centers.
– Keep batteries away from children and pets.
Eufy offers a recycling program in some regions—check their website for details.
