Why You Might Need to Change the Arlo Doorbell Battery

Before diving into the steps, it’s helpful to understand why your Arlo doorbell battery might need replacing. Most Arlo doorbells use a rechargeable lithium-ion battery that lasts several months on a single charge. However, over time, battery performance naturally declines.

Here are common signs it’s time for a new battery:

• Frequent low-battery alerts in the Arlo app: If your doorbell keeps sending notifications about low power, even after charging, the battery may be worn out.
• Doorbell fails to wake up or respond: A dead or failing battery can cause the device to become unresponsive.
• Shorter recording times or missed motion events: Weak batteries may not provide enough power for full functionality.
• Battery won’t hold a charge: If it drains quickly after a full charge, replacement is likely needed.
• Physical damage or swelling: Never use a battery that looks bloated or damaged—this can be a fire hazard.

Regular maintenance, including timely battery changes, ensures your doorbell stays reliable and secure.

What You’ll Need Before Starting

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

• A compatible replacement battery: Use an official Arlo battery or a certified third-party equivalent. Check your model (e.g., Arlo Essential, Pro 3) to ensure compatibility.
• A small Phillips-head screwdriver: Most Arlo doorbells require a screwdriver to remove the faceplate or mounting plate.
• A clean, flat workspace: A table or countertop with good lighting helps prevent losing small parts.
• A microfiber cloth: Use this to clean dust or debris from the doorbell housing.
• Your smartphone with the Arlo app installed: You’ll need this to re-sync the doorbell after battery replacement.
• A fully charged replacement battery: Always charge the new battery for at least 2–4 hours before installing.

Having everything ready saves time and reduces frustration.

Step 1: Turn Off the Doorbell and Disconnect Power

Safety first! Before touching any components, you must disconnect power to avoid electrical shock or damage.

For Battery-Powered Models (Most Common)

If your Arlo doorbell runs on battery power (like the Arlo Essential or Pro 3), it doesn’t have a hardwired connection. However, the battery still supplies power, so you should:

• Open the Arlo app on your phone.
• Go to My Devices and select your doorbell.
• Tap Device Settings > Power Options.
• Choose Turn Off or Sleep Mode to disable the device temporarily.

This step prevents accidental button presses or system errors during battery removal.

For Hardwired Models (With Backup Battery)

Some Arlo doorbells are hardwired to your home’s electrical system but still use a rechargeable battery as a backup. If yours is hardwired:

• Turn off the power at the circuit breaker that controls your doorbell.
• Use a non-contact voltage tester to confirm the wires are not live.
• Proceed only when you’re certain the power is off.

Never skip this step—working on live wires can be dangerous.

Step 2: Remove the Doorbell from the Mounting Plate

Now it’s time to take the doorbell off the wall.

Locate the Release Mechanism

Most Arlo doorbells attach to a mounting plate with either screws or a locking tab.

• Look for a small screw at the bottom of the doorbell (common on Arlo Pro 3).
• Use your Phillips-head screwdriver to loosen and remove it. Keep the screw in a safe place—don’t lose it!
• If your model uses a magnetic or slide-lock system (like the Arlo Essential), gently pull the doorbell away from the plate.

Detach the Doorbell Carefully

Once the screw is removed or the lock is released:

• Hold the doorbell firmly with both hands.
• Tilt it slightly forward and lift it upward to slide it off the mounting plate.
• Be gentle—don’t yank or twist it, as this could damage the internal components.

Place the doorbell face-down on your clean workspace, with the back facing up.

Step 3: Open the Battery Compartment

Now you’ll access the battery inside.

Find the Battery Cover

On most Arlo doorbells, the battery is housed behind a removable panel on the back.

• Look for a small latch or screw near the bottom edge of the back panel.
• If there’s a screw, use your Phillips-head screwdriver to remove it.
• If there’s a latch, press or slide it to release the cover.

Remove the Cover

Once the latch is released or the screw is out:

• Gently lift the battery cover away from the doorbell.
• Set the cover aside—don’t misplace it!
• You should now see the rechargeable battery inside a plastic housing.

Step 4: Remove the Old Battery

With the compartment open, it’s time to take out the old battery.

Disconnect the Battery Connector

The battery is connected to the doorbell via a small plug.

• Locate the white or black connector that links the battery to the circuit board.
• Use your fingers or a plastic spudger (or even a credit card) to gently pry the connector apart.
• Do not use metal tools—they can short-circuit the battery or damage the port.
• Pull the connector straight out—don’t wiggle or twist it.

Lift Out the Battery

Once disconnected:

• Carefully lift the battery out of its housing.
• Hold it by the edges to avoid touching the terminals.
• Place the old battery in a safe, non-conductive container (like a plastic bag) for proper disposal.

Never throw lithium-ion batteries in the regular trash. Take them to a recycling center or electronics store that accepts batteries.

Step 5: Install the New Battery

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

Check the New Battery

Before installing:

• Make sure the new battery is fully charged (check the LED indicator if it has one).
• Verify it’s the correct model for your doorbell (e.g., Arlo BATT-1000).
• Inspect for any damage, swelling, or leaks—do not use if damaged.

Insert the New Battery

• Place the new battery into the compartment, aligning it with the housing.
• Ensure the terminals match the orientation of the old battery (positive and negative sides).
• Press it gently into place—it should fit snugly.

Reconnect the Battery

• Take the connector from the new battery and plug it into the corresponding port on the circuit board.
• Push it in firmly until it clicks or seats completely.
• Double-check that it’s secure—loose connections can cause power issues.

Step 6: Reassemble the Doorbell

With the new battery in place, it’s time to put everything back together.

Replace the Battery Cover

• Align the cover with the back of the doorbell.
• Press it into place until it snaps or sits flush.
• If it uses a screw, reinsert and tighten it—don’t overtighten.

Reattach the Doorbell to the Mounting Plate

• Hold the doorbell and align it with the mounting plate on the wall.
• Slide it downward or press it into place, depending on your model.
• If it uses a screw, reinsert and tighten it at the bottom.
• Ensure it’s secure and level.

Give it a gentle tug to confirm it’s locked in.

Step 7: Power On and Re-Sync the Doorbell

Now that the hardware is back in place, it’s time to restore functionality.

Turn the Power Back On

• If you turned off the circuit breaker, switch it back on.
• If you used sleep mode in the app, go back to Device Settings > Power Options and select Turn On.

Wait for the Doorbell to Boot Up

• The LED light on the front should blink blue or white, indicating it’s connecting.
• This may take 30–60 seconds.
• Don’t press the button yet—let it fully initialize.

Re-Sync with the Arlo App

• Open the Arlo app on your smartphone.
• Go to My Devices and select your doorbell.
• If it doesn’t appear automatically, tap Add Device and follow the setup prompts.
• The app will guide you through re-pairing the doorbell to your Wi-Fi network.

Once synced, test the doorbell by pressing the button. You should hear a chime (if connected to a chime kit) and receive a notification on your phone.

Testing and Final Checks

Before calling it a day, run a few quick tests to ensure everything works.
