Why You Might Need to Change the Eufy Doorbell Battery
Eufy doorbells are designed to run on rechargeable lithium-ion batteries, which typically last between 6 to 12 months depending on usage. However, several factors can drain the battery faster than expected. For example, if you live in a busy neighborhood with lots of foot traffic, your doorbell may detect motion dozens of times a day—each event uses a small amount of power. Similarly, extreme weather—like freezing winters or scorching summers—can reduce battery efficiency.
Other signs that your battery needs replacing include:
- The doorbell frequently disconnects from Wi-Fi
- Live view takes longer than usual to load
- The app shows a “Low Battery” warning
- The doorbell fails to ring or record when someone approaches
- The LED indicator flashes red or doesn’t light up at all
If you notice any of these symptoms, it’s time to check the battery. And while Eufy batteries are built to last, they aren’t meant to be recharged indefinitely. Over time, their capacity decreases, and eventually, they’ll need to be replaced—even if you’ve been diligent about charging them regularly.
What You’ll Need Before You Begin
Before you start the battery replacement process, gather the following items to ensure a smooth and safe experience:
- A compatible Eufy replacement battery: Always use an official Eufy battery designed for your specific doorbell model. Using third-party batteries can damage the device or void your warranty.
- A small Phillips-head screwdriver: Most Eufy doorbells are secured with a single screw at the bottom. A standard Phillips #1 or #2 should work.
- A clean, dry cloth: Use this to wipe down the battery compartment and remove any dust or debris.
- A well-lit workspace: Good lighting helps you see small components and avoid mistakes.
- Your smartphone with the Eufy Security app installed: You’ll need this to test the doorbell after installation.
Optional but helpful:
- A soft-bristled brush (like a clean toothbrush) for cleaning tight spaces
- A magnetic screwdriver to prevent dropping the screw
- A small container to hold the screw while you work
Once you’ve gathered your tools, find a flat, stable surface to work on—like a table or workbench. Avoid working on the ground where small parts can get lost.
Step-by-Step Guide: How to Change Eufy Doorbell Battery
Step 1: Power Down the Doorbell
Before touching any internal components, it’s crucial to power down your Eufy doorbell. This prevents accidental short circuits, protects the internal circuitry, and ensures your safety.
To power down the doorbell:
- Open the Eufy Security app on your smartphone.
- Navigate to your doorbell device.
- Tap the settings icon (usually three dots or a gear symbol).
- Select “Device Settings” and then “Power Off” or “Turn Off Device.”
Wait about 10–15 seconds for the device to fully shut down. You’ll know it’s off when the LED light stops blinking or turns off completely. If your model doesn’t have a visible LED, you can confirm it’s off by checking the app—it should show the device as offline.
Pro Tip: Never remove the battery while the doorbell is powered on. Doing so can cause data corruption or damage the internal memory.
Step 2: Remove the Doorbell from the Mounting Bracket
Most Eufy doorbells are attached to a wall-mounted bracket with a single security screw at the bottom. This screw prevents theft and keeps the doorbell firmly in place.
To remove the doorbell:
- Locate the small screw at the bottom edge of the doorbell.
- Use your Phillips-head screwdriver to loosen and remove the screw. (Keep it in a safe place—you’ll need it later!)
- Gently pull the doorbell away from the wall. It should slide out of the bracket with a slight upward motion.
Be careful not to yank or twist the doorbell forcefully. The wires inside the mounting bracket are not connected to power (since it’s battery-operated), but rough handling can damage the casing or internal components.
Note: Some Eufy models, like the Eufy Video Doorbell 2K (Wired), are hardwired and don’t use batteries. This guide applies only to battery-powered models such as the Eufy Video Doorbell 2K (Battery), Eufy SoloCam Doorbell, and similar versions.
Step 3: Open the Battery Compartment
Once the doorbell is detached, you’ll see a small compartment on the back or bottom side—this houses the rechargeable battery.
To access the battery:
- Look for a small latch or sliding cover. On most models, it’s a rectangular panel with a tiny notch or groove.
- Use your fingernail or a flat tool (like a plastic spudger or credit card) to gently pry open the compartment.
- Slide or lift the cover to reveal the battery inside.
Be gentle—forcing the cover can break the plastic clips. If it feels stuck, double-check that you’ve removed the security screw completely.
Step 4: Remove the Old Battery
Now that the compartment is open, you’ll see the lithium-ion battery securely seated inside.
To remove it:
- Look for a small pull tab or ribbon attached to the battery. This is designed to help you lift it out easily.
- Gently pull the tab upward to lift the battery out of the compartment.
- If there’s no tab, use your fingers to carefully wiggle the battery loose. Avoid using metal tools, as they can scratch or puncture the battery.
Once the battery is out, inspect it for any signs of damage—swelling, leaks, or corrosion. If you notice any of these, handle the battery with care and dispose of it properly at an electronics recycling center. Do not throw it in the regular trash.
Safety Reminder: Lithium-ion batteries can be hazardous if damaged. Always wear gloves if the battery appears compromised, and avoid puncturing or bending it.
Step 5: Clean the Battery Compartment
Before installing the new battery, take a moment to clean the compartment. Dust, dirt, or moisture can interfere with the electrical connection and reduce performance.
To clean:
- Use a dry, lint-free cloth to wipe the inside of the compartment.
- If there’s stubborn grime, lightly dampen the cloth with isopropyl alcohol (70% or higher) and wipe gently. Make sure the compartment is completely dry before proceeding.
- Use a soft-bristled brush to clean around the contact points—these are the metal strips that connect the battery to the doorbell.
A clean compartment ensures a solid connection and helps the new battery deliver maximum power.
Step 6: Install the New Battery
Now it’s time to install your new Eufy battery. Make sure it’s fully charged before installation—even if it comes pre-charged, a full charge ensures optimal performance.
To install:
- Align the new battery with the compartment, matching the positive (+) and negative (−) terminals.
- Slide the battery into place, making sure it sits flat and secure.
- If there’s a pull tab, position it so it’s accessible for future removal.
- Close the battery compartment cover and press firmly until it clicks into place.
Double-check that the cover is fully closed and flush with the doorbell body. A loose cover can allow moisture to enter and damage the internal components.
Step 7: Reattach the Doorbell to the Mounting Bracket
With the new battery installed, it’s time to put the doorbell back on the wall.
To reattach:
- Align the doorbell with the mounting bracket on the wall.
- Slide it downward into place until it’s snug.
- Reinsert the security screw at the bottom and tighten it with your screwdriver.
Don’t overtighten the screw—just snug it enough to hold the doorbell securely. Over-tightening can strip the screw hole or crack the plastic.
Pro Tip: If you’re worried about losing the screw, use a magnetic screwdriver or place a small piece of tape over the screw head while tightening.
Step 8: Power On and Test the Doorbell
Now that everything is back in place, it’s time to power up and test your doorbell.
To power on:
- Open the Eufy Security app.
- Go to your doorbell device.
- Tap “Power On” or “Turn On Device” in the settings.
- Wait 30–60 seconds for the doorbell to reconnect to Wi-Fi and sync with the app.
Once powered on, test the following features:
- Live View: Tap the camera icon in the app to see a real-time feed from your doorbell.
- Motion Detection: Walk in front of the doorbell to trigger a motion alert. Check if you receive a notification.
- Doorbell Ring: Press the doorbell button (if it has one) to test the chime and app notification.
- Battery Level: Check the battery percentage in the app—it should show 100% or close to it.
If everything works correctly, congratulations—you’ve successfully changed your Eufy doorbell battery!
