Why Charging Your Eufy Doorbell Battery Matters

Before diving into the steps, it’s important to understand why proper charging matters. Your Eufy doorbell relies on a rechargeable lithium-ion battery to operate. Unlike wired doorbells, it doesn’t draw power from your home’s electrical system. That means when the battery dies, your doorbell stops working—no video, no alerts, no two-way audio.

Regular and correct charging ensures:
– Consistent performance and reliability
– Longer battery lifespan (typically 2–3 years)
– Fewer interruptions in home security
– Accurate motion detection and night vision

Neglecting proper charging habits—like using third-party chargers or leaving the battery in extreme temperatures—can shorten its life and reduce efficiency. So, let’s make sure you’re doing it right.

What You’ll Need Before You Start

Gathering the right tools and materials beforehand makes the process smoother and safer. Here’s what you’ll need:

• Eufy doorbell unit (with removable battery)
• Official Eufy charging cable and adapter (usually included with purchase)
• Micro-USB or USB-C cable (depending on your model—check your user manual)
• Power source (wall outlet, power bank, or computer USB port)
• Small Phillips-head screwdriver (if your model requires it for removal)
• Clean, dry cloth (for wiping contacts)
• Indoor, temperature-controlled space (avoid garages, attics, or outdoor areas)

Pro Tip: Always charge your battery indoors. Lithium-ion batteries perform best between 50°F and 86°F (10°C to 30°C). Charging in freezing or hot environments can damage the battery.

Step 1: Check Battery Level in the Eufy App

Before you start physically handling the doorbell, check how much charge is left. This helps you decide whether a full recharge is needed or if a quick top-up will do.

Open the Eufy Security App

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

Navigate to Your Doorbell

Tap on the device icon for your doorbell. You’ll see a live view, motion settings, and battery status.

Review Battery Percentage

Look for the battery icon—usually in the top-right corner. It will show a percentage (e.g., 15%, 50%, 100%). If it’s below 20%, it’s time to charge.

Example: If your doorbell shows 12% battery, you’ll want to charge it fully to avoid unexpected shutdowns.

Note Any Alerts

The app may display a low-battery warning. Some models also send push notifications when battery levels drop below 20%. If you see this, plan to charge soon.

Step 2: Turn Off the Doorbell (Recommended)

While Eufy doorbells can technically be charged while mounted, it’s safer and easier to remove the battery first. But before doing that, it’s wise to turn off the device.

Disable Live View and Motion Detection

In the Eufy app, go to your doorbell’s settings. Turn off “Live View” and “Motion Detection” temporarily. This reduces power usage and prevents accidental alerts during removal.

Put the Doorbell in Sleep Mode (If Available)

Some Eufy models have a “Sleep Mode” feature. Activating it conserves battery and makes removal safer.

Why this matters: Even though the battery is removable, the doorbell may still draw a small amount of power from residual charge. Turning it off minimizes risk.

Step 3: Remove the Battery from the Doorbell

Now it’s time to physically remove the battery. The process varies slightly depending on your Eufy model, but here’s the general method.

Locate the Battery Compartment

Most Eufy battery doorbells have a removable faceplate or a side latch. Look for a small indentation or release button.

Release the Faceplate or Latch

– For models with a faceplate: Gently press the release button (usually at the bottom) and pull the front cover away.
– For models with a side latch: Slide the latch to the side and lift the battery out.

Carefully Extract the Battery

Once the compartment is open, lift the battery straight out. It’s typically a flat, rectangular lithium-ion pack with a connector.

Pro Tip: Handle the battery by its edges—avoid touching the metal contacts. Oils from your skin can interfere with charging.

Inspect the Battery and Compartment

Before charging, check for:
– Dust or debris in the compartment
– Corrosion on the contacts
– Physical damage (swelling, cracks, leaks)

If you see swelling or leakage, do not charge. Contact Eufy support immediately—this could indicate a defective battery.

Step 4: Connect the Battery to the Charger

Now that the battery is out, it’s time to plug it in.

Use the Official Eufy Charging Cable

Only use the cable and adapter that came with your doorbell. Third-party chargers may not deliver the correct voltage or current, risking damage.

Connect the Cable to the Battery

Align the connector on the cable with the port on the battery. Gently push it in until it clicks or fits snugly.

Plug Into a Power Source

Connect the other end to a wall outlet, power bank, or USB port. For fastest charging, use the original Eufy adapter (usually 5V/2A).

Important: Avoid using fast chargers (like those for smartphones) unless specified by Eufy. They can overheat the battery.

Check the Charging Indicator

Most Eufy batteries have a small LED light:
– Red or orange: Charging in progress
– Green or blue: Fully charged
– No light: Check connection or power source

If the light doesn’t turn on, double-check the cable connection and power outlet.

Step 5: Monitor Charging Progress

Charging time varies by model and battery capacity, but most Eufy doorbells take 2–4 hours to fully charge.

Check the LED Light Regularly

Every 30–60 minutes, glance at the battery’s LED. Once it turns green, charging is complete.

Use the Eufy App (Optional)

Some newer models allow you to monitor charging status remotely via the app. If available, enable this feature for convenience.

Average Charging Times

– Eufy Video Doorbell 2K: ~3 hours
– Eufy Security Video Doorbell (Battery): ~2.5 hours
– Eufy Video Doorbell Dual: ~4 hours (larger battery)

Pro Tip: Don’t leave the battery charging overnight. While modern lithium-ion batteries have overcharge protection, it’s still best to unplug once full.

Step 6: Reinstall the Battery

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

Disconnect the Charger

Unplug the cable from the battery and power source.

Clean the Contacts (Optional but Recommended)

Wipe the battery’s metal contacts and the doorbell’s internal connectors with a dry, lint-free cloth. This ensures a strong connection.

Insert the Battery

Slide the battery back into the compartment, making sure it’s oriented correctly. The connector should align with the port inside.

Secure the Faceplate or Latch

Snap the front cover back into place or slide the latch closed. You should hear a click or feel it lock.

Press the Doorbell Button

Test the doorbell by pressing the front button. The LED should light up, and you should hear a chime (if connected to a chime kit).

Step 7: Reconnect and Test the Doorbell

Now that the battery is back in, ensure everything is working properly.

Open the Eufy App

Launch the app and check if your doorbell appears online.

Verify Live View

Tap the live view button. You should see a clear video feed within a few seconds.

Test Motion Detection

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

Check Two-Way Audio

Tap the microphone icon and speak. You should hear your voice through the doorbell’s speaker.

Review Battery Status

Confirm the battery shows 100% (or close to it) in the app.

Example: If the app shows 98% after reinstalling, that’s normal—some charge may have been used during startup.

Tips to Maximize Battery Life

Charging correctly is only half the battle. To get the most out of your Eufy doorbell battery, follow these best practices:

Adjust Motion Sensitivity

High sensitivity causes frequent recordings, draining the battery faster. In the app, go to Motion Settings and lower the sensitivity or set activity zones to ignore trees or passing cars.
