What You’ll Need Before Starting

Before you begin, gather the following tools and materials to make the process smooth and safe:

Replacement battery: Check your ADT doorbell model (e.g., ADT Pulse Doorbell, ADT Command Doorbell) to confirm the correct battery type. Most use a rechargeable 18650 lithium-ion battery, but some newer models may use proprietary packs.
Screwdriver: A small Phillips-head screwdriver is usually needed to remove the mounting plate or faceplate.
Soft cloth or microfiber towel: To protect the doorbell’s surface during handling.
USB charging cable: To charge the new battery before installation (if not pre-charged).
ADT app on your smartphone: For reconfiguring and testing the doorbell after replacement.
Optional: Voltage tester or multimeter: To confirm power is off at the doorbell wires (for hardwired models).

Pro tip: Always purchase batteries from reputable suppliers or directly from ADT to avoid counterfeit or low-quality replacements that could damage your device.

Step 1: Identify Your ADT Video Doorbell Model

Not all ADT video doorbells use the same battery type or installation method. Before replacing the battery, confirm your model to avoid compatibility issues.

Common ADT Video Doorbell Models

ADT Pulse Doorbell: Older model, often uses a removable 18650 lithium-ion battery. May be hardwired or battery-powered.
ADT Command Doorbell: Newer model with improved video and integration. Typically uses a built-in rechargeable battery pack.
ADT Smart Doorbell Pro: Features 1080p HD video, night vision, and advanced motion detection. Battery is usually internal and requires disassembly.

To find your model:

Check the label on the back of the doorbell.
Open the ADT app and go to “Devices” > select your doorbell > “Device Info.”
Refer to your original installation manual or contact ADT customer support.

Knowing your model ensures you buy the right battery and follow the correct removal procedure.

Step 2: Turn Off Power (For Hardwired Models)

Safety first! If your ADT video doorbell is hardwired to your home’s electrical system, you must turn off the power before removing it. This prevents electrical shock or short-circuiting.

How to Safely Disconnect Power

Locate your home’s circuit breaker panel. This is usually in the basement, garage, or utility closet.
Find the breaker labeled “Doorbell” or “Front Door.” If unsure, turn off the main breaker for extra safety.
Switch the breaker to the “OFF” position. Use a voltage tester to confirm no power is reaching the doorbell wires.
Wait 2–3 minutes to allow any residual charge to dissipate.

Note: If your doorbell is battery-only (not hardwired), you can skip this step. However, it’s still wise to remove the doorbell from the wall to avoid accidental damage.

Step 3: Remove the ADT Video Doorbell from the Wall

Now that power is off, it’s time to safely detach the doorbell from its mounting bracket.

Step-by-Step Removal

Use a Phillips-head screwdriver to loosen the security screw at the bottom of the doorbell. This screw prevents theft and holds the device in place.
Gently pull the doorbell away from the wall. It should slide out of the mounting bracket with slight pressure.
Disconnect the wires (if hardwired). Carefully unclip the two wires (usually red and white) from the back of the doorbell. Label them or take a photo to remember the connection order.
Place the doorbell on a soft, flat surface like a towel to avoid scratching the lens or casing.

Tip: If the doorbell feels stuck, wiggle it slightly while pulling. Avoid using excessive force, as this could damage the mounting bracket or wires.

Step 4: Access the Battery Compartment

The battery location varies by model. Here’s how to access it for the most common ADT doorbells.

For ADT Pulse Doorbell (Removable Battery)

Flip the doorbell over to reveal the back panel.
Locate the battery compartment cover. It’s usually held in place by two small screws.
Unscrew the cover using a Phillips-head screwdriver.
Lift off the cover to expose the 18650 lithium-ion battery.

For ADT Command or Smart Doorbell Pro (Internal Battery)

Remove the front faceplate. Some models have a snap-on cover that can be pried off with a plastic tool or credit card.
Unscrew any internal screws securing the circuit board or battery housing.
Carefully disconnect the battery connector from the main board. Use a spudger or plastic tool to avoid damaging pins.
Gently lift out the battery pack. It may be secured with adhesive or clips.

Warning: Never use metal tools to pry open the doorbell. This can scratch components or cause short circuits.

Step 5: Remove the Old Battery

Once the battery is accessible, handle it with care to avoid damage or injury.

Safe Battery Removal Tips

Do not puncture, crush, or bend the battery. Lithium-ion batteries can leak or catch fire if damaged.
Avoid touching the metal contacts with bare hands. Oils from your skin can corrode the terminals.
If the battery is swollen or leaking, do not attempt to remove it yourself. Contact ADT or a professional for safe disposal.
Use gloves and eye protection if the battery shows signs of damage.

For removable batteries (like the 18650), simply lift it out of the compartment. For internal packs, disconnect the connector and carefully extract the battery.

Step 6: Install the New Battery

Now it’s time to install the fresh battery and restore power to your doorbell.

Step-by-Step Installation

Ensure the new battery is fully charged. Use the provided USB cable or external charger. A full charge typically takes 2–4 hours.
Check the battery orientation. Match the positive (+) and negative (−) terminals with the compartment markings.
Insert the battery into the compartment. For removable types, slide it in gently. For internal packs, reconnect the connector and secure with screws or clips.
Replace the battery cover or faceplate. Tighten screws securely but avoid over-tightening.

Pro tip: Label the new battery with the installation date so you can track its lifespan (most last 1–2 years).

Step 7: Reattach the Doorbell to the Wall

With the new battery in place, it’s time to reinstall the doorbell.

Reinstallation Steps

Reconnect the wires (if hardwired). Attach the red and white wires to the corresponding terminals on the back of the doorbell.
Slide the doorbell into the mounting bracket. Ensure it clicks into place securely.
Tighten the security screw at the bottom to prevent tampering.
Restore power at the breaker if you turned it off earlier.

Double-check that all connections are tight and the doorbell is level on the wall.

Step 8: Test the ADT Video Doorbell

After installation, verify that everything is working correctly.

Testing Checklist

Open the ADT app and check if the doorbell appears online.
Test the live video feed. Look for clear, stable video with no lag.
Press the doorbell button to trigger a notification on your phone.
Speak through the app to test two-way audio.
Walk in front of the doorbell to confirm motion detection is active.
Check battery level in the app—it should show 100% or close to it.

If any feature isn’t working, proceed to the troubleshooting section below.

Troubleshooting Common Issues After Battery Replacement

Even with careful installation, you might encounter a few hiccups. Here’s how to fix them.
