Eufy doorbells are designed for convenience and reliability. Most models come with rechargeable lithium-ion batteries that can last several months on a single charge, depending on usage. However, over time, battery performance naturally degrades. Frequent motion detection, live viewing, and two-way audio all drain power faster.

Signs it’s time to change or recharge your Eufy doorbell battery include:

  • The doorbell shuts off randomly, even after a recent charge
  • Motion alerts stop working or become delayed
  • The Eufy app shows a low battery warning
  • Video quality drops or recordings fail to save
  • The device becomes unresponsive to button presses

Replacing the battery—or simply recharging it—restores full functionality and ensures your home remains monitored and secure.

What You’ll Need

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

  • A compatible replacement battery (check your model—most use 18650 lithium-ion or built-in packs)
  • A small Phillips-head screwdriver (if your model requires disassembly)
  • A clean, dry cloth
  • A USB charging cable (usually included with your doorbell)
  • A power bank or wall charger (for recharging)
  • Optional: A soft-bristle brush (for cleaning dust)

Always use only Eufy-recommended or high-quality third-party batteries. Cheap or counterfeit batteries can damage your doorbell or pose safety risks.

Step 1: Identify Your Eufy Doorbell Model

Not all Eufy doorbells use the same battery type or removal method. Before proceeding, confirm your model:

  • Eufy Video Doorbell (Battery-Powered): Uses a removable 18650 lithium-ion battery. Common models include the E10, E20, and E30 series.
  • Eufy Video Doorbell (Wired): Some wired models still have a backup battery. Check the user manual.
  • Eufy SoloCam Doorbell: Often has a built-in, non-removable battery that requires professional service.

Check the label on the back of your doorbell or open the Eufy Security app > Device Settings > Device Info to confirm your model.

Step 2: Power Down and Disconnect

Safety first! Even though Eufy doorbells are low-voltage, it’s best to minimize risk.

For Battery-Powered Models:

  1. Open the Eufy Security app on your phone.
  2. Go to your doorbell device and tap “Settings.”
  3. Select “Device Status” and confirm the battery level.
  4. Tap “Turn Off Device” to disable Wi-Fi and motion detection temporarily.

This step isn’t always necessary, but it prevents accidental triggers or data loss during removal.

For Wired Models with Backup Battery:

  1. Turn off power at the circuit breaker that controls your doorbell.
  2. Wait 30 seconds to ensure capacitors discharge.
  3. Use a non-contact voltage tester near the doorbell wires to confirm no power is present.

Never skip this step if your doorbell is hardwired. Live wires can cause shocks or damage electronics.

Step 3: Remove the Doorbell from the Mount

Most Eufy doorbells attach to a mounting plate with a secure clip or screw.

For Clip-On Models:

  1. Insert a flathead screwdriver or the included removal tool into the small slot at the bottom of the doorbell.
  2. Gently pry upward until the doorbell pops off the mount.
  3. Support the doorbell with your other hand to avoid dropping it.

For Screw-Secured Models:

  1. Use a Phillips-head screwdriver to remove the security screw at the bottom.
  2. Lift the doorbell straight up and away from the mount.

Place the doorbell on a soft surface, like a towel, to avoid scratching the lens or casing.

Step 4: Access the Battery Compartment

Now it’s time to get to the battery.

For Removable Battery Models (e.g., E10, E20):

  1. Flip the doorbell over to see the back panel.
  2. Locate the battery compartment—usually a rectangular slot with a latch or screw cover.
  3. Use your fingernail or a small tool to release the latch.
  4. Slide out the old battery carefully.

For Models with Screw-On Covers:

  1. Unscrew the two small screws on the back using a Phillips-head screwdriver.
  2. Lift off the cover to reveal the battery.
  3. Note the orientation of the battery (positive and negative ends) before removing it.

Always handle the battery by its edges. Avoid touching the metal contacts with your fingers, as oils can reduce conductivity.

Step 5: Remove the Old Battery

Once the compartment is open:

  1. Gently wiggle the battery loose if it’s snug.
  2. Pull it straight out—do not twist or force it.
  3. If the battery is swollen or leaking, do not touch it directly. Wear gloves and place it in a non-flammable container. Contact Eufy support or your local hazardous waste facility for disposal.

Never puncture, crush, or expose lithium-ion batteries to water or heat.

Step 6: Clean the Battery Compartment

Before inserting the new battery, take a moment to clean:

  1. Use a dry cloth to wipe away dust or debris from the compartment.
  2. Check the metal contacts—clean them gently with a cotton swab if needed.
  3. Ensure no moisture is present. If the doorbell was exposed to rain, let it dry completely before proceeding.

Clean contacts ensure a strong connection and prevent power issues.

Step 7: Insert the New or Recharged Battery

Now for the fun part—putting in the fresh battery.

For Removable Batteries:

  1. Align the new battery with the correct polarity (match the + and – markings).
  2. Slide it into the compartment until it clicks or sits flush.
  3. Close the latch or replace the cover and tighten screws securely.

For Built-In Batteries (Non-Removable):

  1. If your model has a sealed battery, you’ll need to charge it in place.
  2. Connect the USB cable to the charging port (usually on the back or bottom).
  3. Plug the other end into a wall charger or power bank.
  4. Charge for at least 6–8 hours or until the indicator light turns green.

Always use the original charging cable or a high-quality replacement. Low-quality cables can cause slow charging or overheating.

Step 8: Reattach the Doorbell to the Mount

With the battery in place:

  1. Align the doorbell with the mounting plate.
  2. Press firmly until you hear a click (for clip-on models).
  3. For screw-secured models, reinsert the security screw and tighten it snugly—don’t over-tighten.

Ensure the doorbell is level and secure. A loose mount can cause false motion alerts or damage the device.

Step 9: Power On and Test

Now it’s time to see if everything works.

  1. Open the Eufy Security app.
  2. Tap your doorbell device to check the connection.
  3. If the device is offline, wait 1–2 minutes for it to reconnect.
  4. Test the doorbell by pressing the button—you should hear a chime and see a live feed.
  5. Walk in front of the doorbell to trigger motion detection and confirm alerts appear on your phone.

If the doorbell doesn’t turn on, double-check the battery orientation and connections.

Step 10: Optimize Battery Performance

To get the most out of your new battery:

  • Enable Smart Alerts: In the app, adjust motion zones and sensitivity to reduce unnecessary recordings.
  • Use Scheduled Recording: Set the doorbell to record only during high-traffic hours (e.g., evenings).
  • Turn Off Night Vision (if not needed): Infrared LEDs drain power—disable them in well-lit areas.
  • Update Firmware: Go to Device Settings > Firmware Update to ensure your doorbell runs efficiently.
  • Charge Regularly: Recharge every 3–6 months, even if the battery isn’t fully drained.

These small tweaks can extend battery life by up to 30%.

  • Don’t Leave on the Charger: Once fully charged, unplug the doorbell to prevent overcharging (though most modern models have protection).
  • Clean Monthly: Wipe the lens and sensors with a microfiber cloth to maintain clarity and sensitivity.
  • Check for Updates: Eufy regularly releases firmware that improves battery efficiency.

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 at least 2–3 months under normal use.
  • Replace if: The battery swells, leaks, or loses charge in under a month.
  • Replace if: The doorbell shuts off even after a full 8-hour charge.

Most Eufy batteries last 1–2 years with regular use. After that, performance declines.

Safety Warnings and Best Practices

Battery safety is critical. Follow these rules:

  • Never use damaged, swollen, or leaking batteries.
  • Do not expose batteries to fire, water, or extreme temperatures.
  • Keep batteries away from children and pets.
  • Dispose of old batteries at a certified recycling center—do not throw in regular trash.
  • If a battery overheats or smokes, move it to a safe area and call emergency services if needed.

Eufy batteries are designed for safety, but misuse can lead to serious risks.
