Let’s get started!

Why Changing the Battery Matters

Your ADT doorbell is more than just a doorbell—it’s a key part of your home security system. It lets you see who’s at the door, talk to visitors remotely, and receive alerts when motion is detected. But all of these features depend on one thing: power.

Most ADT doorbells are either hardwired into your home’s electrical system with a backup battery or are completely battery-powered. Over time, even rechargeable batteries lose their ability to hold a charge. When the battery runs low, your doorbell may:

– Fail to ring when someone presses the button
– Show a “low battery” warning in the ADT app
– Have a dim or flickering camera
– Stop sending motion or doorbell alerts
– Disconnect from your Wi-Fi network

Replacing the battery promptly ensures your doorbell stays online and functional. It also prevents false alarms or missed visitors, keeping your home secure and your peace of mind intact.

Identifying Your ADT Doorbell Model

Before you begin, it’s essential to know which ADT doorbell you have. Different models have different battery types and access methods. Here are the most common ADT doorbell models and how to identify them:

ADT Pulse Doorbell Camera

This is one of the most popular models. It’s a video doorbell with two-way audio, motion detection, and night vision. It’s typically hardwired but includes a rechargeable lithium-ion battery as a backup. Look for a rectangular design with a camera lens and LED ring around the button.

ADT Command Doorbell

Part of the newer ADT Command system, this model offers HD video, cloud storage, and integration with smart home devices. It may be wired or wireless, depending on installation. The battery compartment is usually on the back or bottom.

ADT Wireless Doorbell (Battery-Only Models)

These models run entirely on batteries—often AA or AAA—and are ideal for homes without existing doorbell wiring. They’re easy to install and remove, making battery changes straightforward.

How to Find Your Model Number

To confirm your model:
– Check the back or bottom of the doorbell unit
– Look at the original packaging or installation manual
– Log into the ADT app or website and view your device list
– Contact ADT customer support with your account info

Once you know your model, you can proceed with confidence. The steps below are tailored to cover the most common scenarios, but always refer to your user manual for model-specific instructions.

Gathering Your Tools and Materials

You don’t need a full toolbox to change the battery in your ADT doorbell, but having the right items on hand will make the process smoother and safer.

Essential Tools

• Screwdriver: Most ADT doorbells use Phillips-head screws. A small #1 or #2 Phillips screwdriver is usually sufficient.
• Replacement battery: Check your manual for the correct type. Common options include:
  • Rechargeable lithium-ion battery (e.g., 3.7V 18650 or similar)
  • AA or AAA alkaline batteries (for wireless models)
• Safety gloves (optional): To protect your hands and prevent static discharge.
• Soft cloth or microfiber towel: For cleaning the doorbell and battery compartment.
• Flashlight: To illuminate tight spaces, especially if your doorbell is in a dim area.

Optional but Helpful

• Needle-nose pliers (for removing small connectors)
• Isopropyl alcohol and cotton swabs (for cleaning contacts)
• Labeling tape (to mark wires if disconnecting)

Where to Buy Replacement Batteries

You can purchase replacement batteries from:
– The official ADT website or customer service
– Authorized retailers like Home Depot, Best Buy, or Amazon
– Electronics stores such as RadioShack or Batteries Plus

Always choose high-quality, name-brand batteries to ensure safety and longevity. Avoid cheap knockoffs, as they may leak, overheat, or damage your device.

Step-by-Step: How to Change the Battery in Your ADT Doorbell

Now that you’ve identified your model and gathered your tools, it’s time to get to work. Follow these steps carefully to replace the battery safely and effectively.

Step 1: Turn Off the Power

Safety first! Even if your doorbell is battery-powered, it’s wise to turn off the power at the breaker if it’s hardwired. This prevents accidental short circuits or electrical shocks.

• Locate your home’s electrical panel (breaker box).
• Find the circuit labeled “doorbell” or “chime.” If unsure, turn off the main power or the circuit closest to your front door.
• Use a non-contact voltage tester to confirm the power is off at the doorbell.

Tip: If you’re not comfortable working with electricity, consider turning off the main breaker or consulting an electrician.

Step 2: Remove the Doorbell from the Mount

Most ADT doorbells are attached to a mounting plate with screws. You’ll need to remove the unit to access the battery.

• Use your screwdriver to remove the screws on the bottom or sides of the doorbell.
• Gently pull the doorbell away from the wall. Be careful—there may be wires connected if it’s hardwired.
• If wired, take a photo of the wire connections before disconnecting them. This will help you reconnect them correctly later.
• Label the wires with tape if needed (e.g., “front,” “transformer”).
• Disconnect the wires by loosening the terminal screws or unplugging the connectors.

Note: Wireless models can simply be lifted off the mount without disconnecting wires.

Step 3: Locate the Battery Compartment

Once the doorbell is removed, look for the battery compartment. Its location varies by model:

• ADT Pulse Doorbell: The battery is usually behind a panel on the back or bottom. You may need to remove additional screws.
• ADT Command Doorbell: The battery is often housed in a removable tray or accessed via a latch.
• Wireless Models: The battery compartment is typically on the back and secured with a sliding cover or screws.

Use your flashlight to get a clear view. If the compartment is dirty, wipe it gently with a dry cloth.

Step 4: Remove the Old Battery

Carefully extract the old battery:

• If it’s a rechargeable lithium-ion battery, note the orientation (positive and negative ends).
• Use your fingers or needle-nose pliers to gently pull the battery out. Avoid using excessive force.
• If the battery is stuck, check for a release tab or clip. Some models have a small lever to eject the battery.
• For AA/AAA batteries, simply slide them out of the compartment.

Safety Tip: Never puncture, crush, or expose lithium-ion batteries to heat. Dispose of them properly at a recycling center.

Step 5: Clean the Battery Compartment

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

• Use a dry cloth to remove dust or debris.
• If there’s corrosion (white or green powder), lightly dab it with a cotton swab dipped in isopropyl alcohol. Let it dry completely.
• Check the battery contacts for dirt or oxidation. Clean them gently to ensure a good connection.

A clean compartment helps the new battery make proper contact and last longer.

Step 6: Install the New Battery

Now it’s time to install the replacement:

• Match the polarity: Ensure the positive (+) and negative (−) ends of the battery align with the markings in the compartment.
• Slide or place the battery into position. It should fit snugly without forcing.
• For rechargeable models, make sure the battery clicks into place or is secured with a latch.
• For AA/AAA batteries, insert them in the correct direction as indicated by the symbols.

Double-check the orientation—installing a battery backward can damage the doorbell.

Step 7: Reattach the Doorbell

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

• Reconnect the wires if your model is hardwired. Match the labels or refer to your photo.
• Tighten the terminal screws securely, but don’t overtighten.
• Align the doorbell with the mounting plate and press it into place.
• Reinsert and tighten the mounting screws.

Make sure the doorbell is flush against the wall and doesn’t wobble.

Step 8: Restore Power and Test

Now that everything is reassembled:

• Turn the power back on at the breaker.
• Wait 30–60 seconds for the doorbell to boot up.
• Open the ADT app on your phone and check the device status.
• Look for a “battery full” or “connected” indicator.
• Press the doorbell button to test the chime and camera.
• Walk in front of the doorbell to test motion detection.

If everything works, congratulations—you’ve successfully changed the battery!

Troubleshooting Common Issues

Even with careful installation, you might run into problems. Here’s how to fix the most common issues:

Doorbell Won’t Turn On After Battery Replacement

• Check that the battery is inserted correctly and fully charged.
• Ensure the power is restored at the breaker.
