Introduction: Why Changing Your SimpliSafe Doorbell Battery Matters
If you’ve installed a SimpliSafe doorbell, you already know how convenient it is to see who’s at your door—even when you’re not home. But like any battery-powered smart device, it won’t work forever without a little maintenance. One of the most common issues users face is a dead or dying battery.

In this guide, we’ll walk you through every step of the battery replacement process. Whether you’re a tech newbie or a DIY pro, you’ll find clear instructions, safety tips, and troubleshooting advice to make the job easy and stress-free. By the end, you’ll know exactly how to remove the old battery, install a new one, and get your doorbell back online in no time.

Before diving into the replacement process, it’s important to gather the right tools and materials. Having everything ready will save you time and prevent mistakes.
Required Tools and Materials
- Replacement battery: SimpliSafe uses a proprietary 3.7V lithium-ion rechargeable battery (model RB-3V1). You can purchase this directly from SimpliSafe or authorized retailers. Avoid generic batteries—they may not fit or could damage your doorbell.
- Small Phillips-head screwdriver: Needed to remove the mounting plate or access panel, depending on your doorbell model.
- Soft cloth or microfiber towel: Useful for cleaning the doorbell housing and preventing scratches.
- Optional: Rubber gloves: While not required, they can help protect your hands and keep the battery clean.
Safety Precautions
Even though the SimpliSafe doorbell is low-voltage, it’s still connected to your home’s wiring. To stay safe:
- Turn off power at the breaker: Locate your home’s electrical panel and switch off the circuit that powers your doorbell. This prevents accidental shocks or short circuits.
- Wait 5–10 minutes: Give the system time to fully power down before touching any components.
- Avoid water and moisture: Never attempt battery replacement in rainy or humid conditions. Work in a dry, well-lit area.
- Handle the battery gently: Lithium-ion batteries can be dangerous if punctured, crushed, or exposed to heat. Do not use metal tools to pry the battery out.
Step 1: Locate Your SimpliSafe Doorbell Model
SimpliSafe offers a few doorbell models, and while the battery replacement process is similar, it’s good to know which one you have.
Identify Your Doorbell
The most common model is the SimpliSafe Video Doorbell Pro, which features a built-in camera, motion detection, and two-way audio. Older versions may have slightly different designs, but all use the same type of rechargeable battery.
To confirm your model:
- Check the back of the doorbell for a label with the model number.
- Open the SimpliSafe app and go to Devices > Doorbell to see the model name.
- Look at the shape: The Video Doorbell Pro has a rectangular face with a camera lens in the center and a light ring around the button.
Knowing your model helps ensure you get the correct replacement battery and follow the right steps.
Step 2: Power Down the System
Safety first! Before touching any part of the doorbell, you need to disconnect power.
Turn Off the Breaker
- Go to your home’s main electrical panel (breaker box).
- Find the circuit labeled “doorbell” or “chime.” If it’s not labeled, turn off the breaker that controls your front door area.
- Flip the switch to the “OFF” position.
- Test the doorbell by pressing the button—if nothing happens, power is off.
Alternative: Remove the Existing Battery
If you can’t access the breaker or prefer not to shut off power, you can simply remove the current battery. However, this method is riskier because the doorbell may still have residual charge. Only do this if you’re confident and careful.
Step 3: Remove the Doorbell from the Wall
Now that power is off, it’s time to take the doorbell off the wall.
Unscrew the Mounting Plate
- Use your Phillips-head screwdriver to remove the two screws on the bottom of the doorbell.
- Gently pull the doorbell away from the wall. It should come off easily—don’t force it.
- You’ll see wires connected to the back. These are low-voltage, but still, avoid touching them unnecessarily.
Disconnect the Wires (If Necessary)
Some models have wires connected to the back of the doorbell. If yours does:
- Take a photo of the wiring setup for reference.
- Use the screwdriver to loosen the terminal screws and carefully disconnect the wires.
- Label them (e.g., “Front” and “Trans”) so you can reconnect them correctly later.
If your doorbell is wireless (battery-only), there will be no wires—just a mounting plate.
Step 4: Access the Battery Compartment
With the doorbell removed, you can now access the battery.
Locate the Battery Cover
On the SimpliSafe Video Doorbell Pro, the battery is housed inside the main unit. There’s no external compartment—you’ll need to open the device.
Remove the Faceplate
- Flip the doorbell over so the back is facing up.
- You’ll see a small latch or seam near the bottom.
- Gently press or slide the latch to release the faceplate.
- Lift the faceplate off carefully. It’s usually held by clips, so avoid using excessive force.
Expose the Battery
Once the faceplate is off, you’ll see the internal components. The battery is a small, rectangular block connected by a thin wire and connector.
Step 5: Remove the Old Battery
Now it’s time to take out the old battery.
Disconnect the Battery Connector
- Locate the small plastic connector that links the battery to the circuit board.
- Use your fingers or a plastic spudger (not metal!) to gently pull the connector straight out.
- Do not pull on the wires—only the connector itself.
Remove the Battery
- The battery is usually held in place by a small bracket or adhesive.
- If there’s a bracket, unscrew it with your Phillips-head screwdriver.
- If it’s taped, gently peel it off. Avoid bending or puncturing the battery.
- Carefully lift the battery out of the compartment.
Dispose of the Old Battery Properly
Lithium-ion batteries should never go in regular trash. Instead:
- Take it to a local electronics recycling center.
- Many stores like Best Buy or Home Depot have battery drop-off bins.
- Check with your city’s waste management for hazardous material disposal options.
Step 6: Install the New Battery
With the old battery out, it’s time to install the new one.
Prepare the New Battery
- Make sure the replacement battery is fully charged. SimpliSafe batteries usually come pre-charged, but it’s best to check.
- Use a USB charger and the included cable to charge it for at least 2–3 hours if needed.
- Inspect the battery for any damage—cracks, swelling, or leaks mean it’s defective and shouldn’t be used.
Place the Battery in the Compartment
- Position the new battery in the same orientation as the old one.
- If there’s a bracket, secure it with the screw.
- If it was taped, use a small piece of double-sided tape (included with some replacements) to hold it in place.
Reconnect the Battery Connector
- Align the connector with the port on the circuit board.
- Gently push it in until it clicks or sits flush.
- Do not force it—misalignment can damage the connector.
Step 7: Reassemble the Doorbell
Now that the battery is in, put everything back together.
Reattach the Faceplate
- Align the faceplate with the main body.
- Press it down gently until all clips snap into place.
- Make sure there are no gaps or loose edges.
Reconnect Wires (If Applicable)
If you disconnected wires earlier:
- Reconnect them to the correct terminals using your photo as a guide.
- Tighten the screws securely, but don’t over-tighten.
Step 8: Reattach the Doorbell to the Wall
With the doorbell reassembled, it’s time to mount it back.
Position the Doorbell
- Hold the doorbell against the wall, aligning it with the mounting plate.
- Make sure it’s level and at a comfortable height (usually 48 inches from the ground).
Secure with Screws
- Insert the two screws into the bottom of the doorbell.
- Tighten them with your screwdriver until snug—don’t overtighten, as this can crack the plastic.
Step 9: Restore Power and Test
Now for the moment of truth—does it work?
Turn the Breaker Back On
- Return to your electrical panel.
- Flip the doorbell breaker back to the “ON” position.
Wait for the Doorbell to Boot Up
- The doorbell will take 30–60 seconds to power on.
- You’ll see the light ring glow, and the camera may activate.
Test the Doorbell
- Press the doorbell button. You should hear a chime inside your home.
- Open the SimpliSafe app and check if the doorbell appears online.
- Test the live view, motion detection, and two-way audio.
If everything works, congratulations—you’ve successfully changed the battery!
Troubleshooting Common Issues
Even with careful steps, problems can happen. Here’s how to fix the most common ones.
Doorbell Doesn’t Power On
- Check the breaker: Make sure power is restored.
- Verify battery connection: Open the doorbell and ensure the connector is fully seated.
