Why Your Kangaroo Doorbell Battery Needs Replacing

Smart doorbells like the Kangaroo models rely on rechargeable or replaceable batteries to function, especially if they’re wireless. Over time, these batteries lose their ability to hold a charge. You might notice signs like:

• The doorbell frequently disconnects from Wi-Fi
• Motion alerts stop working
• The live video feed is slow or fails to load
• The app shows a “low battery” warning
• The doorbell doesn’t ring when someone presses the button

These symptoms usually mean the battery is nearing the end of its life. Most Kangaroo doorbells use CR123A lithium batteries, which typically last 6 to 12 months depending on usage, climate, and settings like motion sensitivity. Cold weather can drain batteries faster, so if you live in a colder region, you may need to replace them more often.

Replacing the battery promptly ensures your doorbell stays online, your home remains secure, and you don’t miss important visitors or deliveries.

What You’ll Need to Change the Battery

Before you begin, gather these items to make the process quick and hassle-free:

• New CR123A lithium battery (check your model’s manual to confirm—most Kangaroo doorbells use this type)
• Screwdriver (usually a small Phillips head, but some models use a Torx or security screw)
• Soft cloth or cotton swab (for cleaning battery contacts)
• Step ladder (if your doorbell is mounted high)
• Kangaroo app (installed on your smartphone for re-syncing)

Optional but helpful:

• Gloves (to protect your hands)
• Flashlight (if lighting is poor)
• Small container (to hold screws so they don’t get lost)

Always purchase high-quality batteries from reputable brands like Duracell, Energizer, or Amazon Basics. Cheap or counterfeit batteries may not last as long and could leak, damaging your device.

Step 1: Turn Off the Doorbell and Prepare the Area

Safety first! Before touching any part of your doorbell, make sure it’s powered down to avoid accidental shocks or short circuits—even though it’s battery-powered, it’s still connected to your home’s electrical system if it’s wired.

For Battery-Only Models

If your Kangaroo doorbell runs solely on battery (no wiring), you can skip turning off the power. However, it’s still a good idea to remove the battery temporarily to ensure the device is completely off.

For Wired Models with Battery Backup

Many Kangaroo doorbells are wired into your home’s doorbell circuit but also have a rechargeable or replaceable battery for backup power. In this case:

1. Turn off the power at the circuit breaker that controls your doorbell. This is usually labeled “doorbell,” “chime,” or “front door.” If you’re unsure, turn off the main breaker to be safe.
2. Wait 30 seconds to ensure all power is drained.
3. Use a non-contact voltage tester near the doorbell wires to confirm no electricity is flowing.

Once the power is off, set up your ladder securely. Make sure it’s on level ground and have someone hold it if possible. Never lean too far to one side while on a ladder.

Step 2: Remove the Kangaroo Doorbell from the Mount

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

Locate the Release Mechanism

Most Kangaroo doorbells are attached to a mounting plate with screws or a twist-lock system.

• Screw-mounted models: Use your screwdriver to remove the screws on the bottom or side of the doorbell. Keep them in a small container so they don’t get lost.
• Twist-lock models: Gently twist the doorbell counterclockwise while holding the base. It should pop off easily.

Be careful not to drop the doorbell. If it’s connected by wires, don’t pull too hard—there should be enough slack to remove it safely.

Disconnect Wires (If Applicable)

If your doorbell is wired, you’ll see two small wires (usually red and black or white) connected to the back.

• Take a photo of the wiring before disconnecting—this helps when reattaching later.
• Gently pull the wire connectors straight out. Do not yank or twist them.
• Wrap the exposed ends with electrical tape to prevent short circuits.

Now you can fully remove the doorbell and place it on a flat, clean surface like a table or workbench.

Step 3: Open the Battery Compartment

With the doorbell removed, locate the battery compartment. The location varies slightly by model:

• Kangaroo Doorbell Cam: The battery compartment is on the back, near the bottom. It’s covered by a small panel held in place by a screw.
• Kangaroo Doorbell Pro: The battery is accessed from the side or bottom, often behind a sliding cover or secured with a screw.

Remove the Cover

Use your screwdriver to remove the screw(s) holding the battery cover in place. Set the screw aside safely.

If your model has a sliding or snap-on cover, gently pry it open with your fingers or a plastic spudger (to avoid scratching).

Inspect the Compartment

Before removing the old battery, take a moment to inspect the compartment:

• Look for corrosion, rust, or white powder around the contacts—this indicates battery leakage.
• If you see residue, clean it gently with a cotton swab dipped in a small amount of vinegar or isopropyl alcohol. Let it dry completely before inserting a new battery.
• Check that the contacts are clean and free of dust. Wipe them with a dry cloth if needed.

A clean compartment ensures a strong connection and prevents future issues.

Step 4: Remove the Old Battery

Now it’s time to take out the old battery.

Identify the Battery Orientation

Most CR123A batteries are installed with the positive (+) terminal facing up or toward the front of the device. Take note of how the old battery is positioned—this ensures you install the new one correctly.

Gently Remove the Battery

CR123A batteries are usually held in place by a spring or clip.

• Use your fingers to gently push the battery away from the spring and lift it out.
• If it’s stuck, use a plastic tool (like a spudger or credit card) to pry it loose. Avoid metal tools, which can damage the compartment.

Never force the battery out. If it’s swollen or leaking, wear gloves and dispose of it immediately.

Dispose of the Old Battery Properly

Lithium batteries should never go in regular trash. They contain hazardous materials and can start fires in landfills.

• Take the old battery to a certified recycling center, hardware store (like Home Depot or Lowe’s), or battery drop-off location.
• Many electronics retailers offer free battery recycling programs.

Proper disposal protects the environment and keeps your community safe.

Step 5: Install the New Battery

With the old battery removed and the compartment clean, it’s time to install the new one.

Check the New Battery

Before inserting, inspect the new CR123A battery:

• Make sure it’s not damaged, dented, or leaking.
• Confirm the expiration date is far in the future.
• Ensure the positive (+) and negative (–) ends are clearly marked.

Insert the Battery Correctly

Follow the orientation you noted earlier:

• Place the battery into the compartment with the positive (+) terminal facing the correct direction (usually up or toward the front).
• Press it gently into place until it’s secure and the spring or clip holds it firmly.
• Do not force it—if it doesn’t fit easily, double-check the orientation.

A properly installed battery will sit flush and not wobble.

Replace the Cover

Once the battery is in:

• Align the battery cover and press it into place.
• If it uses a screw, reinsert and tighten it securely—don’t overtighten, as this can strip the screw or crack the plastic.
• If it’s a snap-on cover, press firmly until you hear a click.

Step 6: Reattach the Doorbell to the Mount

Now that the battery is replaced, it’s time to put the doorbell back on the wall.

Reconnect Wires (If Applicable)

If your doorbell is wired:

• Remove the electrical tape from the wire ends.
• Reconnect the wires to the corresponding terminals on the back of the doorbell (match the colors or labels).
• Push the connectors in firmly until they click.

Attach the Doorbell to the Mount

• Align the doorbell with the mounting plate.
• For screw-mounted models, reinsert and tighten the screws.
• For twist-lock models, align the tabs and twist clockwise until it locks.

Make sure the doorbell is level and secure. Give it a gentle tug to confirm it’s firmly attached.

Restore Power

If you turned off the circuit breaker:

• Go back to the breaker panel and turn the power back on.
• Wait 30–60 seconds for the doorbell to power up.

Step 7: Test and Re-Sync the Doorbell

After installation, it’s crucial to test the doorbell to ensure everything is working.

Check the App

Open the Kangaroo app on your smartphone:
