Why Your Vivint Doorbell Battery Needs Replacing

Vivint doorbells are designed to be low-maintenance, but they do rely on a rechargeable or replaceable battery to function when not hardwired. Most Vivint models—like the Vivint Doorbell Camera Pro—use a removable CR123A lithium battery. Over time, this battery loses its charge capacity, especially in extreme temperatures or with heavy usage.

Here are common signs it’s time for a battery change:

  • Low battery notifications: The Vivint app will alert you when the battery level drops below 20%.
  • Delayed or missed motion alerts: A weak battery may cause the doorbell to “sleep” more often to conserve power.
  • Video quality issues: Blurry footage, lag, or failure to record can indicate insufficient power.
  • Doorbell not responding to button presses: If the chime doesn’t sound or the app doesn’t show a live feed, the battery may be dead.
  • Device powers off unexpectedly: Sudden shutdowns are a clear sign the battery can’t hold a charge.

Replacing the battery promptly ensures your doorbell stays online and ready to protect your home. Most users find that a single CR123A battery lasts between 6 and 12 months, depending on how often the doorbell is triggered and the climate in your area.

What You’ll Need Before You Begin

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

  • A new CR123A lithium battery: This is the standard battery used in Vivint doorbells. Avoid generic or alkaline versions—lithium batteries provide consistent voltage and longer life.
  • A clean, dry cloth: Use this to wipe down the doorbell and remove dust or debris.
  • A small Phillips-head screwdriver (optional): Some models may have a security screw, though most use a simple latch.
  • A ladder or step stool: If your doorbell is mounted high, ensure you can reach it safely.
  • Your smartphone or tablet: You’ll need this to check the Vivint app during testing.

Pro tip: Buy a pack of CR123A batteries so you always have a spare on hand. They’re widely available at hardware stores, electronics retailers, and online.

Step 1: Turn Off Power to Your Doorbell

Safety first! Even though your Vivint doorbell runs on battery power, it’s still connected to your home’s electrical system if it’s hardwired. To prevent any risk of electrical shock or damage to the device, you should turn off the power at the breaker.

Locate Your Electrical Panel

Find your home’s main electrical panel (also called the breaker box). It’s usually in the garage, basement, or utility closet. Open the panel door and look for the circuit labeled “doorbell,” “front door,” or something similar. If you’re unsure which breaker controls the doorbell, turn them off one by one and test the doorbell button until it stops working.

Switch Off the Breaker

Once you’ve identified the correct breaker, flip it to the “off” position. This cuts power to the doorbell transformer, ensuring no electricity flows to the device while you’re handling it.

Test the Doorbell

Press the doorbell button to confirm it no longer chimes. If it still works, double-check your breaker labels or try another breaker. Never proceed until you’re certain the power is off.

Note: If your doorbell is battery-only (not hardwired), you can skip this step. However, it’s still a good idea to remove the battery before handling the device.

Step 2: Remove the Vivint Doorbell from the Mounting Plate

Now that the power is off, it’s time to take the doorbell off the wall. Vivint doorbells are designed for easy removal, but you’ll need to be gentle to avoid damaging the mounting plate or the device itself.

Locate the Release Latch

Look at the bottom edge of your doorbell. You’ll see a small latch or tab. This is the release mechanism that holds the doorbell securely to the mounting plate.

Press the Latch and Slide Down

Use your thumb to press the latch inward (toward the wall). While holding it down, gently slide the entire doorbell downward. It should come free with a slight tug. If it feels stuck, wiggle it slightly while pressing the latch—don’t force it.

Set the Doorbell on a Soft Surface

Once removed, place the doorbell face-down on a soft cloth or towel to protect the lens and sensors from scratches.

Pro tip: Take a photo of the mounting plate and wiring before removing the doorbell. This helps you remember how everything connects if you need to reattach it later.

Step 3: Open the Battery Compartment

With the doorbell removed, you’re ready to access the battery. The battery compartment is located on the back of the device, protected by a secure cover.

Find the Battery Cover

Flip the doorbell over. On the back, you’ll see a small rectangular cover with a latch or screw. Most Vivint models use a simple latch, but some may have a security screw to prevent tampering.

Release the Latch or Unscrew the Cover

If your model has a latch, press it gently and slide the cover open. If it has a screw, use a small Phillips-head screwdriver to remove it. Keep the screw in a safe place—you’ll need it to reassemble the doorbell.

Inspect the Battery Compartment

Before removing the old battery, take a moment to check the compartment for dust, corrosion, or moisture. If you see any debris, use a dry cloth or compressed air to clean it out. Never use water or cleaning solutions near the battery terminals.

Warning: Do not touch the battery terminals with wet hands or metal objects. This can cause a short circuit or damage the doorbell’s internal components.

Step 4: Remove the Old Battery

Now it’s time to take out the old battery. Handle it carefully to avoid damaging the compartment or the new battery you’re about to install.

Identify the Battery Orientation

Look at how the old battery is positioned. Note which end is positive (+) and which is negative (–). Most CR123A batteries have the positive end marked with a “+” symbol. Taking a photo can help you remember the correct orientation.

Gently Lift the Battery Out

Use your fingers or a plastic tool (like a spudger) to lift the battery from the compartment. Avoid using metal tools, as they can scratch the contacts or cause a short.

Dispose of the Old Battery Properly

CR123A batteries contain lithium and should not be thrown in the regular trash. Take them to a local battery recycling center, electronics store, or hazardous waste facility. Many retailers, like Best Buy or Home Depot, offer free battery recycling.

Pro tip: Keep a small container in your garage or utility room to collect used batteries until you can recycle them.

Step 5: Install the New Battery

With the old battery removed, you’re ready to install the new one. This step is crucial—installing the battery incorrectly can prevent the doorbell from working or even damage the device.

Check the New Battery

Before inserting it, inspect the new CR123A battery for any damage, leaks, or corrosion. Make sure it’s fully charged and within its expiration date (usually printed on the packaging).

Insert the Battery Correctly

Align the battery with the compartment, matching the positive (+) and negative (–) ends to the markings inside. Gently press it into place until it sits flush. You should hear a soft click when it’s secure.

Double-Check the Orientation

Before closing the compartment, verify that the battery is installed correctly. If it’s reversed, the doorbell won’t power on.

Pro tip: Use a battery with a fresh date code (within 2–3 years). Older batteries may not hold a full charge, even if they appear new.

Step 6: Reassemble the Doorbell

With the new battery in place, it’s time to put everything back together. Take your time to ensure all parts are secure and aligned properly.

Close the Battery Cover

Slide the cover back into place or reinsert the screw if your model uses one. Make sure it’s tight but don’t over-tighten—this can strip the screw or crack the plastic.

Reattach the Doorbell to the Mounting Plate

Hold the doorbell with the lens facing outward. Align the top edge with the mounting plate and slide it upward until it clicks into place. Press the release latch to confirm it’s secure.

Turn the Power Back On

Return to your electrical panel and flip the breaker back to the “on” position. Wait a few seconds for the system to reset.

Pro tip: If your doorbell has a status light, watch for it to flash or change color. This indicates it’s powering up and reconnecting to Wi-Fi.

Step 7: Test Your Vivint Doorbell

Now that everything is reassembled and powered on, it’s time to test your doorbell to make sure it’s working properly.

Check the Vivint App

Open the Vivint app on your smartphone or tablet. Go to the doorbell camera section and look for a live feed. If the video loads, the doorbell is receiving power and connected to Wi-Fi.

Test the Doorbell Button

Press the doorbell button. You should hear a chime (either from a wired chime or a smart speaker) and receive a notification on your phone.

Test Motion Detection

Walk in front of the doorbell to trigger motion detection. The app should show a live feed and record a short clip. Check the video quality—it should be clear and responsive.

Check Battery Status

In the Vivint app, go to device settings and check the battery level. It should show 100% or close to it. If it shows a low percentage, the battery may be defective or not fully charged.

If everything works, congratulations—you’ve successfully changed the battery in your Vivint doorbell!
