Your Arlo doorbell is a key part of your home security system. It alerts you when someone approaches, lets you see and speak to visitors, and records important footage. But all of that depends on a reliable power source—and that means a healthy battery.
Over time, rechargeable batteries lose their ability to hold a charge. Even high-quality lithium-ion batteries, like the ones used in Arlo doorbells, typically last 6 to 12 months with regular use. When the battery starts to weaken, you might notice:
– Frequent disconnections from the Arlo app
– Delayed motion alerts
– Poor video quality or freezing
– The doorbell going offline for no reason
– A low battery notification in the app
Ignoring these signs can leave your home vulnerable. That’s why it’s important to change the battery promptly and correctly. Doing so ensures your doorbell stays online, responsive, and ready to protect your home.
What You’ll Need Before You Start
Before you begin, gather the following items to make the process smooth and safe:
- A compatible 18650 rechargeable lithium-ion battery: Arlo doorbells use a specific type of battery. Check your model’s manual or the Arlo website to confirm compatibility. Popular options include the Arlo Rechargeable Battery or third-party brands like Nitecore or EBL (ensure they’re 3.7V and protected).
- A small Phillips-head screwdriver: Needed to remove the security screw on the bottom of the doorbell.
- A soft cloth or towel: To protect the doorbell and surrounding area during removal.
- A fully charged spare battery (optional but recommended): So you can swap it in immediately without waiting to recharge.
- Access to your home’s electrical panel (if hardwired): If your doorbell is connected to existing doorbell wiring, you’ll need to turn off the power at the breaker.
Having these tools ready will save you time and prevent frustration mid-process.
Step 1: Check the Battery Level in the Arlo App
Before you physically change the battery, confirm that it’s actually low. The Arlo app makes this easy.
Open the Arlo App
Launch the Arlo app on your smartphone or tablet. Make sure you’re logged into the correct account.
Navigate to Your Doorbell
Tap on the “Devices” tab at the bottom of the screen. Find your doorbell in the list and select it.
Check the Battery Status
Look for the battery icon near the top of the screen. It will show a percentage (e.g., 20%) or a warning message like “Low Battery.” If it’s below 20%, it’s definitely time for a change.
Even if the battery isn’t critically low, you might still want to replace it if you’ve had the same battery for over a year or if performance has declined.
Step 2: Power Down the Doorbell (If Hardwired)
If your Arlo doorbell is hardwired to your home’s electrical system, you must turn off the power before removing it. This prevents electrical shock and protects the device.
Locate Your Electrical Panel
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet).
Find the Doorbell Circuit
Look for a breaker labeled “Doorbell,” “Chime,” or something similar. If it’s not labeled, you may need to test breakers by turning them off one at a time and checking if the doorbell stops working.
Turn Off the Breaker
Switch the breaker to the “OFF” position. Use a voltage tester if you’re unsure—there should be no power flowing to the doorbell wires.
Tip: If you’re not comfortable working with electrical panels, consider hiring an electrician or using a battery-only installation.
Step 3: Remove the Arlo Doorbell from the Wall
Now it’s time to take the doorbell off the wall. Be gentle—this part requires care to avoid damaging the device or the mounting plate.
Locate the Security Screw
At the bottom of the doorbell, you’ll see a small screw. This is a security feature to prevent theft.
Unscrew It with a Phillips-Head Screwdriver
Turn the screw counterclockwise until it’s loose. Don’t remove it completely—just loosen it enough to release the doorbell.
Gently Pull the Doorbell Away from the Wall
Once the screw is loose, carefully pull the doorbell straight out from the mounting plate. It should slide out easily.
Important: If your doorbell is hardwired, the wires will still be connected. Do not yank or pull hard—support the doorbell with one hand while disconnecting the wires with the other.
Disconnect the Wires (If Hardwired)
If your doorbell is connected to wires, gently disconnect them from the back of the device. Most Arlo doorbells use quick-connect terminals—just press the release tab and pull the wire out.
Lay the doorbell on a soft cloth to protect the lens and casing.
Step 4: Remove the Old Battery
With the doorbell removed, you can now access the battery compartment.
Open the Battery Cover
On the back of the doorbell, locate the small latch or sliding cover that protects the battery. Use your fingernail or a flat tool to gently open it.
Carefully Remove the Old Battery
The battery will be seated in a slot. Gently lift it out by the edges. Avoid touching the metal contacts with your fingers—oils from your skin can reduce performance.
Inspect the Battery and Compartment
Check for any signs of damage, swelling, or corrosion. If the battery is swollen or leaking, do not touch it with bare hands. Dispose of it properly at a battery recycling center.
Safety Tip: Never puncture, crush, or expose lithium-ion batteries to heat or water.
Step 5: Insert the New Battery
Now it’s time to install the fresh battery.
Check the Battery Orientation
Look at the markings inside the battery compartment. There should be a “+” and “–” symbol indicating the correct direction. Match this with the markings on your new battery.
Insert the Battery
Slide the new battery into the slot with the positive (+) end aligned correctly. It should fit snugly but not require force.
Close the Battery Cover
Secure the cover by pressing it back into place until it clicks. Make sure it’s fully closed to protect the battery from moisture and dust.
Step 6: Reattach the Doorbell to the Wall
With the new battery in place, it’s time to reinstall the doorbell.
Reconnect the Wires (If Hardwired)
If your doorbell was hardwired, reconnect the wires to the terminals on the back. Push each wire in until it clicks. Double-check that they’re secure.
Align the Doorbell with the Mounting Plate
Hold the doorbell up to the wall and align it with the mounting plate. Slide it back into place until it’s flush.
Tighten the Security Screw
Use your screwdriver to tighten the security screw at the bottom. Don’t over-tighten—just enough to hold the doorbell firmly in place.
Restore Power (If Hardwired)
Go back to your electrical panel and turn the breaker back on. Wait a few seconds for the doorbell to power up.
Step 7: Test the Doorbell
After installation, make sure everything is working correctly.
Open the Arlo App
Launch the app and check if your doorbell appears online.
Check the Battery Level
Confirm that the battery percentage has updated and shows a high charge (e.g., 100%).
Test the Camera and Audio
Tap the live view button to see the video feed. Speak into your phone to test the two-way audio.
Trigger a Motion Alert
Walk in front of the doorbell to see if it detects motion and sends a notification.
Ring the Doorbell
Press the button to ensure the chime sounds and you receive an alert.
If everything works, congratulations—you’ve successfully changed the battery!
