Let’s get started!

Why Charging Your Eufy Doorbell Battery Matters

Your eufy doorbell runs on a rechargeable lithium-ion battery, which powers features like motion detection, two-way audio, night vision, and live streaming. Over time, the battery will drain—especially if you receive frequent motion alerts or use the live view often. If the battery dies completely, your doorbell won’t work, leaving your front door unmonitored.

Regular charging ensures:
– Continuous security coverage
– Reliable performance during peak usage
– Longer overall battery lifespan
– Fewer unexpected outages

Most eufy doorbell models (like the eufy Video Doorbell 2K, Doorbell Dual, and Doorbell Slim) have batteries that last 3–6 months on a single charge, depending on usage. But if you notice the battery draining faster than usual, it might be time to check your charging routine.

What You’ll Need to Charge Your Eufy Doorbell Battery

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

• Original USB-C charging cable (included with your eufy doorbell)
• Compatible USB charger (5V/2A recommended; avoid fast chargers unless specified)
• Screwdriver (usually a Phillips #1 or #2, depending on your model)
• Clean, dry cloth (for wiping contacts)
• Well-lit, dry workspace (like a table near an outlet)
• Optional: Step ladder (if your doorbell is mounted high)

Avoid using third-party cables or chargers, as they may not deliver the correct voltage and could damage the battery or void your warranty.

Step 1: Prepare for Safe Removal

Safety comes first. Before touching your doorbell, take these precautions:

Turn Off Power at the Breaker

Even though your eufy doorbell is battery-powered, it may still be connected to existing doorbell wires. To avoid electrical shock or short-circuiting, turn off the power to your doorbell at the main electrical panel. Look for the breaker labeled “doorbell” or “chime.” If you’re unsure, turn off the entire circuit for your front entry.

Wait 5–10 Minutes

After turning off the power, wait a few minutes to ensure any residual electricity dissipates. This is especially important if your doorbell was hardwired.

Check the App for Battery Level

Open the eufy Security app on your phone and check the battery percentage. If it’s below 20%, it’s definitely time to charge. The app will also show if the doorbell is online and functioning.

Step 2: Remove the Eufy Doorbell from the Mount

Now it’s time to safely detach your doorbell from the wall.

Locate the Release Screw

Most eufy doorbells have a small security screw at the bottom of the device. Use your screwdriver to loosen and remove it. Keep the screw in a safe place—you’ll need it to reattach the doorbell later.

Gently Pull the Doorbell Away

Once the screw is removed, gently pull the doorbell straight away from the mounting plate. It should come off easily. If it feels stuck, wiggle it slightly—don’t force it.

Disconnect Any Wires (If Applicable)

If your doorbell was hardwired, you’ll see two small wires connected to the back. Carefully disconnect them by pulling the wire connectors straight out. Don’t cut the wires—just unplug them. Label them if needed (e.g., “front” and “transformer”) for easier reinstallation.

Store the Doorbell Safely

Place the doorbell on a clean, flat surface. Avoid dropping it or exposing it to moisture.

Step 3: Remove the Battery from the Doorbell

Not all eufy doorbells have user-replaceable batteries, but most do. Here’s how to access yours.

Locate the Battery Compartment

On the back of the doorbell, you’ll find a small compartment held by one or two screws. Use your screwdriver to remove them.

Open the Compartment

Gently lift the cover to reveal the rechargeable battery. It’s usually a flat, rectangular lithium-ion pack.

Disconnect the Battery

The battery connects to the doorbell via a small plug. Carefully unplug it by pulling the connector straight out. Do not yank or twist the wires.

Handle the Battery with Care

Lithium-ion batteries are sensitive. Avoid puncturing, crushing, or exposing them to heat. Hold the battery by its edges and keep it away from metal objects.

Step 4: Charge the Eufy Doorbell Battery

Now that the battery is out, it’s time to charge it properly.

Use the Original USB-C Cable

Plug the USB-C end into the battery’s charging port. Make sure it’s fully inserted—there should be a slight click or resistance when connected.

Connect to a Compatible Charger

Plug the USB-A end into a 5V/2A wall charger. Avoid using laptop USB ports, power banks, or fast chargers unless they’re specifically approved by eufy. High-voltage chargers can overheat the battery.

Charge in a Safe Environment

Place the battery on a non-flammable surface like wood or ceramic. Charge it indoors at room temperature (ideally between 50°F and 86°F or 10°C–30°C). Never charge in direct sunlight, near heaters, or in freezing conditions.

Monitor the Charging Process

The battery doesn’t have a built-in light, so you’ll need to check the eufy app or wait for the estimated time. A full charge typically takes 4–6 hours. You can plug the battery back into the doorbell temporarily to check the charge level in the app—just don’t reinstall it yet.

Avoid Overcharging

While modern lithium-ion batteries have built-in protection against overcharging, it’s still best to unplug once fully charged. Leaving it plugged in for days can reduce long-term battery health.

Step 5: Reinstall the Battery and Doorbell

Once fully charged, it’s time to put everything back together.

Reconnect the Battery

Plug the battery connector back into the doorbell. Make sure it’s secure and the compartment cover fits snugly. Replace the screws.

Reattach the Doorbell to the Mount

Align the doorbell with the mounting plate on the wall. Slide it into place until it clicks. Reinsert the security screw at the bottom and tighten it with your screwdriver.

Reconnect Wires (If Hardwired)

If you disconnected wires earlier, plug them back into the terminals on the back of the doorbell. Make sure they’re secure.

Turn the Power Back On

Go to your electrical panel and turn the breaker back on. Wait a minute for the doorbell to power up.

Step 6: Test Your Eufy Doorbell

After reinstalling, make sure everything works correctly.

Check the App

Open the eufy Security app. The doorbell should appear online with a full or high battery icon. If it shows “offline,” wait a few minutes or restart the app.

Test Live View

Tap “Live View” in the app to see the camera feed. Make sure the video is clear and the audio works.

Test Motion Detection

Walk in front of the doorbell to trigger motion. You should receive a notification on your phone.

Test Two-Way Audio

Press the talk button in the app and speak. You should hear your voice through the doorbell’s speaker, and vice versa.

Tips for Maintaining Your Eufy Doorbell Battery

To extend battery life and reduce charging frequency, follow these best practices:

Keep the Lens Clean

Dirt, dust, and spiderwebs can trigger false motion alerts, draining the battery faster. Wipe the lens monthly with a microfiber cloth.

Adjust Motion Sensitivity

In the app, go to Device Settings > Motion Detection and lower the sensitivity if you’re getting too many alerts from passing cars or trees.

Use Activity Zones

Set up activity zones to focus on areas like your front walkway and ignore sidewalks or streets.

Avoid Extreme Temperatures

Cold weather reduces battery efficiency. If you live in a cold climate, consider charging more frequently in winter.

Update Firmware Regularly

eufy releases updates that improve battery performance. Check for updates in the app under Device Settings > Firmware Update.

Troubleshooting Common Charging Issues

Even with careful handling, you might run into problems. Here’s how to fix them:

Battery Won’t Charge

– Ensure the USB cable and charger are working. Try charging another device with the same setup.

Charging Takes Too Long

– Use a 5V/2A charger, not a low-power USB port.
– Avoid charging in cold environments.
– Replace the USB cable if it’s damaged.

How Often Should You Charge Your Eufy Doorbell Battery?

The frequency depends on usage, but here’s a general guideline:

• Light use (few motion events per day): Charge every 4–6 months
• Moderate use (10–20 alerts per day): Charge every 2–3 months
• Heavy use (constant motion, frequent live views): Charge every 1–2 months

Use the eufy Security app to monitor battery level and set up low-battery notifications. The app will alert you when the battery drops below 20%, giving you time to charge before it dies.

Can You Charge the Eufy Doorbell While It’s Installed?

Technically, yes—some users try to charge the doorbell while it’s still mounted by threading the USB cable through the mounting plate. However, this is not recommended for several reasons:

– The cable can get pinched or damaged.
– It may interfere with the doorbell’s motion sensor.
– Water or moisture could enter through the cable hole.
– It’s harder to monitor the charging process.

For safety and reliability, always remove the doorbell to charge the battery.

What to Do If Your Battery Won’t Hold a Charge

If your eufy doorbell battery no longer holds a charge, it may be time for a replacement. Here’s what to do:

Check Warranty

eufy offers a 18-month to 2-year warranty on most doorbells. If your device is under warranty and the battery fails prematurely, contact eufy support for a free replacement.

Buy a Genuine Replacement

Purchase a new battery directly from eufy or an authorized retailer. Third-party batteries may not meet safety standards and could damage your doorbell.

Recycle the Old Battery

Lithium-ion batteries should not go in the trash. Take them to an electronics recycling center or a battery drop-off location.
