Before you begin, it’s important to know which type of ADT doorbell you have. ADT offers several doorbell models, and the battery replacement process can vary slightly depending on whether your device is wired or wireless.
Wireless ADT Doorbells
Wireless models, such as the ADT Doorbell Camera Pro, run entirely on battery power. These are popular because they’re easy to install and can be placed almost anywhere near your front door. Since they don’t rely on your home’s wiring, they’re ideal for renters or homes without existing doorbell wiring.
These models typically use rechargeable lithium-ion batteries or standard alkaline batteries (like AA or AAA). The battery compartment is usually located on the back or bottom of the device and can be accessed by removing a cover or sliding panel.
Wired ADT Doorbells
Wired ADT doorbells are connected directly to your home’s electrical system through low-voltage wiring. While they don’t rely on batteries for primary power, some models include a backup battery to keep the doorbell functioning during power outages.
If your wired doorbell has a backup battery, it’s usually a small lithium coin cell (like a CR2032) located inside the main unit. Replacing this battery is less common but still necessary every few years.
How to Identify Your Model
To determine your exact model, check the label on the back or bottom of your doorbell. It will usually include the model number (e.g., “ADT-DB100” or “ADT Doorbell Camera Pro”). You can also log into your ADT app or visit the ADT support website and enter your device serial number to find detailed information.
Knowing your model helps ensure you purchase the correct replacement battery and follow the right steps.
Tools and Materials You’ll Need
Thankfully, changing the battery in an ADT doorbell doesn’t require a full toolbox. Most of what you need is probably already in your home. Here’s a quick checklist:
- Replacement battery: Check your user manual or the old battery to confirm the correct type (e.g., lithium-ion, AA, AAA, or CR2032).
- Screwdriver (if needed): Some models require a small Phillips or flathead screwdriver to remove the faceplate or battery cover.
- Soft cloth or microfiber towel: Use this to clean the doorbell and prevent fingerprints or smudges.
- Flashlight (optional): Helpful if you’re working in a dimly lit area or need to see small components.
- Gloves (optional): Wearing gloves can protect your hands and prevent oils from your skin from damaging sensitive electronics.
Pro tip: Always buy high-quality batteries from reputable brands like Duracell, Energizer, or Panasonic. Cheap batteries may leak or fail prematurely, which can damage your doorbell.
Safety First: Preparing for Battery Replacement
Safety is important, especially when dealing with electrical devices. Even though doorbells use low voltage, it’s still wise to take precautions—particularly with wired models.
For Wired Doorbells: Turn Off the Power
If your ADT doorbell is wired, the first step is to turn off the power at the circuit breaker. Here’s how:
- Locate your home’s electrical panel (usually in the basement, garage, or utility closet).
- Find the breaker labeled “Doorbell,” “Chime,” or something similar. If you’re unsure, turn off the main breaker to be safe.
- Flip the breaker to the “Off” position.
- Test the doorbell by pressing the button—if it doesn’t ring, the power is off.
Never skip this step! Even low-voltage systems can cause a shock or damage your doorbell if mishandled.
For Wireless Doorbells: Remove from Mounting Bracket
Wireless models are easier to handle because they’re not connected to wiring. However, you’ll still want to remove the doorbell from its mounting bracket to access the battery compartment safely.
Most wireless ADT doorbells snap into place with a simple twist or slide mechanism. Gently pull the front of the doorbell away from the wall while pressing the release tab (if present). If it’s stuck, wiggle it slightly—don’t force it.
Let the Device Cool Down
If your doorbell has been in direct sunlight or has been actively recording, give it a few minutes to cool down before handling. Hot electronics are more fragile and prone to damage.
Step-by-Step: Changing the Battery in a Wireless ADT Doorbell
Now that you’re prepared, let’s walk through the battery replacement process for a wireless ADT doorbell. We’ll use the ADT Doorbell Camera Pro as an example, but the steps are similar for most wireless models.
Step 1: Remove the Doorbell from the Wall
As mentioned earlier, gently detach the doorbell from its mounting bracket. Most models have a release tab on the bottom or side. Press it and pull the doorbell straight out.
Once removed, place it on a clean, flat surface—like a table or countertop—with the front facing up.
Step 2: Locate the Battery Compartment
Flip the doorbell over to examine the back. Look for a small panel or cover that’s secured with screws or a snap-on design.
On the ADT Doorbell Camera Pro, the battery compartment is usually on the back, near the bottom. It may be labeled “Battery” or have a small battery icon.
Step 3: Open the Battery Cover
If the cover is held in place by screws, use a small Phillips screwdriver to remove them. Keep the screws in a safe place—like a cup or magnetic tray—so you don’t lose them.
If it’s a snap-on cover, gently pry it open with your fingers or a plastic opening tool (to avoid scratching the surface).
Step 4: Remove the Old Battery
Once the compartment is open, you’ll see the old battery. Note its orientation—how the positive (+) and negative (-) ends are positioned. This is crucial for installing the new battery correctly.
Carefully lift the battery out. If it’s a rechargeable lithium-ion battery, it may be connected with a small plug. Unplug it gently by pulling the connector, not the wires.
Dispose of the old battery responsibly. Most hardware stores or recycling centers accept used batteries.
Step 5: Insert the New Battery
Take your new battery and insert it into the compartment, matching the orientation of the old one. Make sure the positive and negative ends align with the markings inside the compartment.
If it’s a rechargeable battery with a connector, plug it in securely. You should hear a soft click when it’s properly connected.
Step 6: Close the Battery Cover
Once the new battery is in place, replace the cover. If it’s a snap-on design, press it firmly until it clicks. If it uses screws, reinsert them and tighten gently—don’t over-tighten, as this can crack the plastic.
Step 7: Reattach the Doorbell to the Wall
Align the doorbell with the mounting bracket and slide or snap it back into place. Make sure it’s secure and level.
Step 8: Test the Doorbell
Press the doorbell button to see if it rings. If your model has a camera, open the ADT app and check the live feed. Look for clear video, audio, and motion detection.
If everything works, you’re all set! If not, double-check the battery orientation and connections.
Step-by-Step: Changing the Backup Battery in a Wired ADT Doorbell
If you have a wired ADT doorbell with a backup battery, the process is a bit different. These batteries are smaller and located inside the main unit.
Step 1: Turn Off the Power
As emphasized earlier, always turn off the power at the breaker before working on a wired doorbell.
Step 2: Remove the Faceplate
Most wired ADT doorbells have a faceplate that covers the internal components. Use a screwdriver to remove the screws holding it in place.
Once the screws are out, gently pull the faceplate away from the wall. Be careful—there may still be wires connected.
Step 3: Locate the Backup Battery
Inside, look for a small, flat battery—usually a CR2032 coin cell—mounted in a plastic holder. It’s often near the chime mechanism or circuit board.
Step 4: Remove the Old Battery
Use a small flathead screwdriver or your fingernail to gently pry the old battery out of its holder. Note the orientation (positive side up or down).
Step 5: Insert the New Battery
Place the new CR2032 battery into the holder, matching the orientation of the old one. Press it down until it’s secure.
Step 6: Reassemble the Doorbell
Replace the faceplate and tighten the screws. Make sure all wires are tucked neatly inside and nothing is pinched.
Step 7: Restore Power and Test
Turn the breaker back on and test the doorbell. The backup battery should keep it working during brief power outages.
Troubleshooting Common Issues
Even after replacing the battery, you might run into problems. Here are some common issues and how to fix them:
