Regular charging not only keeps your doorbell working but also helps maintain battery health. Lithium-ion batteries perform best when charged consistently and not allowed to fully drain repeatedly. By learning how to charge battery on ADT doorbell properly, you’ll ensure your home security system stays active and reliable.

What You’ll Need

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

  • The original USB charging cable that came with your ADT doorbell (or a compatible one)
  • A standard USB wall adapter (5V/1A or 5V/2A recommended)
  • A clean, dry cloth
  • A small Phillips-head screwdriver (if your model requires it)
  • A well-lit workspace

Using the original charger is important. Third-party cables or adapters may not deliver the correct voltage, which can damage the battery or cause slow charging. If you’ve lost your original cable, check ADT’s website or contact customer support for a replacement.

Step 1: Turn Off the Doorbell

Before handling any electrical components, safety comes first. Even though your ADT doorbell runs on battery power, it’s still connected to your home’s Wi-Fi network and may have residual power. To avoid short circuits or accidental damage, turn off the doorbell through the ADT app.

How to Turn Off the Doorbell via the ADT App

  1. Open the ADT app on your smartphone or tablet.
  2. Tap on the “Devices” tab at the bottom of the screen.
  3. Find your doorbell in the list and tap on it.
  4. Look for a “Power” or “Device Status” option and toggle it to “Off.”
  5. Wait about 10–15 seconds for the device to fully power down.

If your doorbell doesn’t have a software power-off option, you can skip this step—just proceed carefully. However, turning it off reduces the risk of glitches during battery removal.

Step 2: Remove the Doorbell from the Mounting Bracket

Most ADT doorbells are designed to be easily removed for charging. They attach to a mounting bracket using either screws or a snap-on mechanism. Here’s how to safely detach it.

For Snap-On Models (Most Common)

  1. Stand on a stable step ladder if needed to reach the doorbell.
  2. Gently pull the bottom edge of the doorbell away from the wall.
  3. The unit should release with a slight tug—don’t force it.
  4. Lift the doorbell straight up to disconnect it from the bracket.

For Screw-Secured Models

  1. Use a Phillips-head screwdriver to remove the security screw at the bottom of the doorbell.
  2. Once the screw is out, gently wiggle the doorbell to loosen it.
  3. Lift it upward to detach from the bracket.

Be careful not to drop the doorbell. If it’s high up, have someone assist you or use a soft surface below to cushion any accidental drops.

Step 3: Locate and Remove the Battery

Once the doorbell is in your hands, you’ll need to access the battery compartment. On most ADT models, the battery is housed inside the main unit and requires opening a small panel.

Finding the Battery Compartment

  • Look for a small latch or screw on the back or bottom of the doorbell.
  • On some models, the battery is accessed by removing the front faceplate.

  3. Plug the adapter into a wall outlet.

You should see a small LED light on the battery or cable turn on, indicating charging has started. If there’s no light, check the connections and try a different outlet.

How Long to Charge

Most ADT doorbell batteries take 4 to 6 hours to fully charge from empty. Avoid overcharging—once the LED turns green or stops blinking, the battery is full. Unplug it to prevent unnecessary strain on the battery.

Charging times may vary slightly depending on the model and battery capacity. For example:

  • ADT Doorbell Pro: ~5 hours
  • ADT Smart Doorbell (2nd Gen): ~4.5 hours
  • Older models: up to 6 hours

If your battery takes much longer than expected, it may be aging and need replacement.

Step 5: Clean the Battery and Contacts

While the battery charges, take a moment to clean it and the doorbell’s internal contacts. Dust, dirt, or corrosion can interfere with charging and performance.

Cleaning Steps

  1. Use a clean, dry cloth to wipe the battery’s metal contacts.
  2. Gently clean the inside of the battery compartment in the doorbell.
  3. Avoid using water or cleaning sprays—moisture can damage electronics.
  4. If you see corrosion (white or green powder), use a cotton swab lightly dampened with rubbing alcohol. Let it dry completely before reassembly.

Clean contacts ensure a strong electrical connection, which helps the battery charge efficiently and last longer.

Step 6: Reinstall the Battery

Once the battery is fully charged and everything is clean, it’s time to put it back.

Reconnecting the Battery

  1. Align the battery correctly in the compartment—most have a specific orientation.
  2. Gently push the connector plug back into the circuit board until it clicks.
  3. Secure the battery in place and close the compartment.
  4. If there’s a screw, tighten it firmly but don’t over-tighten.

Double-check that the battery is seated properly. A loose connection can cause the doorbell to malfunction or show false low-battery warnings.

Step 7: Reattach the Doorbell to the Mounting Bracket

Now that the battery is back in, reattach the doorbell to the wall.

For Snap-On Models

  1. Align the top of the doorbell with the mounting bracket.
  2. Press the bottom edge firmly until it clicks into place.
  3. Gently tug to confirm it’s secure.

For Screw-Secured Models

  1. Slide the doorbell onto the bracket.
  2. Insert and tighten the security screw at the bottom.
  3. Ensure it’s snug but not over-tightened.

Make sure the doorbell is level and facing the correct direction for optimal camera coverage.

Step 8: Power On and Test the Doorbell
