- Low battery alerts in the app: The Eufy Security app will notify you when the battery drops below 20%. This is your first clue.
- Doorbell not responding: If the doorbell doesn’t ring, record video, or connect to Wi-Fi, a dead battery could be the culprit.
- Dim or flickering video: Poor video quality can indicate low power, especially in cold weather.
- Device shuts off randomly: Intermittent power loss is a classic sign of a failing battery.
- Battery won’t hold a charge: If you’ve charged it multiple times and it drains quickly, the battery may be worn out.
Most Eufy doorbells use a rechargeable 18650 lithium-ion battery, which typically lasts 3–6 months on a single charge, depending on usage, motion sensitivity, and climate. In colder regions, battery life may shorten due to reduced efficiency in low temperatures.
Replacing the battery isn’t just about restoring function—it’s also about maintaining security. A dead doorbell means no alerts, no recordings, and no way to see who’s at your door. That’s why regular maintenance, including timely battery changes, is essential.
Tools and Materials You’ll Need
Before you begin, gather these items to ensure a smooth battery replacement process:
- Replacement 18650 lithium-ion battery: Make sure it’s compatible with your Eufy model (3.7V, 2600mAh or higher). Popular brands include Eufy’s official battery, Samsung, LG, or Panasonic.
- Screwdriver (usually Phillips #0 or #1): Needed to remove the mounting plate or faceplate, depending on your model.
- Microfiber cloth: For cleaning the doorbell and battery compartment.
- Gloves (optional): To protect your hands and avoid transferring oils to the battery.
- Smartphone with Eufy app installed: To check battery status and reconnect the device.
- Charging cable (if recharging instead of replacing): Some users prefer to remove and recharge the battery externally.
Pro tip: Always buy batteries from reputable sources. Cheap, counterfeit batteries can overheat, leak, or even damage your doorbell. Stick to well-known brands or Eufy’s official replacements for safety and performance.
Step 1: Check Your Battery Level in the Eufy App
Before you climb up to your doorbell, check the battery status in the Eufy Security app. This helps confirm whether a battery change is truly needed or if there’s another issue.
How to Check Battery Level
- Open the Eufy Security app on your smartphone.
- Tap on your doorbell device from the home screen.
- Go to Device Settings (usually a gear icon).
- Look for Battery Level or Power Status. It will show a percentage (e.g., 15%).
If the battery is below 20%, it’s time to recharge or replace it. If it’s above 50% but the doorbell isn’t working, the issue might be Wi-Fi, firmware, or a hardware fault—not the battery.
Note: Some Eufy models, like the wired versions, don’t use batteries at all. This guide applies only to battery-powered models such as the Eufy Video Doorbell (Battery) or SoloCam Doorbell.
Step 2: Power Down the Doorbell (If Possible)
While Eufy doorbells are designed to be safe to handle while powered, it’s best practice to minimize risk. If your model allows, power it down before removing the battery.
How to Safely Power Down
- For battery-only models: There’s no external power switch, so simply removing the battery will cut power.
- For dual-powered models (battery + wired): Turn off the circuit breaker that supplies power to the doorbell. This prevents any electrical interference during battery removal.
Even if your doorbell runs solely on battery, turning off the Wi-Fi or disabling motion detection in the app can help reduce power drain during the process.
Step 3: Remove the Eufy Doorbell from the Wall
Now it’s time to physically remove the doorbell from its mounting bracket. The method varies slightly depending on your Eufy model, but the general process is similar.
For Most Eufy Battery Doorbells (e.g., Video Doorbell 2K)
- Locate the release tab at the bottom of the doorbell. It’s usually a small button or lever.
- Press and hold the tab while gently pulling the doorbell away from the wall.
- The device should slide out of the mounting bracket easily.
For Models with Screw-On Faceplates
- Use a Phillips screwdriver to remove the screw(s) on the bottom or side of the doorbell.
- Carefully lift off the faceplate to expose the battery compartment.
Tip: If the doorbell feels stuck, wiggle it slightly while pulling. Avoid using excessive force, as this could damage the mounting bracket or the device itself.
Once removed, place the doorbell on a flat, clean surface—like a table or counter—to work on it safely.
Step 4: Open the Battery Compartment
With the doorbell in hand, locate the battery compartment. On most Eufy models, it’s on the back or bottom of the device.
How to Access the Battery
- Look for a small latch or sliding cover labeled “Battery” or marked with a battery icon.
- Use your fingernail or a flat tool (like a plastic spudger) to gently pry open the compartment.
- Some models may require removing a screw to access the battery—use your screwdriver if needed.
Inside, you’ll see the 18650 battery seated in a plastic tray. It may be held in place by a small clip or friction fit.
Important: Do not force the compartment open. If it doesn’t budge, double-check for hidden screws or latches. Forcing it could crack the casing.
Step 5: Remove the Old Battery
Now that the compartment is open, it’s time to remove the old battery.
Steps to Safely Remove the Battery
- Note the battery’s orientation—how it’s positioned (positive and negative ends). Take a photo if needed.
- Gently lift the battery out of the tray. If it’s stuck, use a non-metal tool to pry it loose.
- Avoid touching the metal terminals with your fingers. Oils from your skin can corrode the contacts over time.
- Place the old battery in a safe, non-conductive container (like a plastic bag) until you can recycle it.
Warning: Never puncture, crush, or expose lithium-ion batteries to heat. They can catch fire or explode if mishandled.
If you’re recharging the battery instead of replacing it, use a compatible 18650 charger. Do not charge it inside the doorbell unless the model specifically supports it.
Step 6: Insert the New Battery
With the old battery removed, it’s time to install the new one. This step is critical—installing the battery incorrectly can damage the doorbell or prevent it from working.
How to Install the New Battery
- Check the new battery for damage—look for dents, leaks, or swelling. Do not use if damaged.
- Align the battery correctly: The positive (+) end should match the marking in the compartment (usually a red wire or “+” symbol).
- Slide the battery into the tray, ensuring it sits flat and secure.
- Close the battery compartment and snap or screw it shut.
Tip: If the battery feels loose, double-check the model compatibility. Some 18650 batteries are slightly larger or smaller than others.
Once installed, give the doorbell a gentle shake to ensure the battery doesn’t rattle. A secure fit is essential for reliable operation.
Step 7: Reattach the Doorbell to the Wall
With the new battery in place, it’s time to remount the doorbell.
Steps to Reinstall
- Align the doorbell with the mounting bracket on the wall.
- Slide it into place until you hear a click or feel it lock.
- If your model uses a screw, reinsert and tighten it securely—but don’t overtighten.
- Ensure the doorbell is level and facing forward for optimal motion detection and video quality.
Pro tip: Use a small level to check alignment. A crooked doorbell can affect video framing and deterrent effectiveness.
After mounting, step back and make sure the doorbell is firmly attached. It should not wobble or move when touched.
Step 8: Power On and Test the Doorbell
Now that everything is back in place, it’s time to test your work.
How to Test the Doorbell
- Wait 10–15 seconds for the doorbell to power on. You should see lights or hear a startup sound.
