Your Arlo doorbell is more than just a doorbell—it’s your first line of defense for home security. It alerts you when someone’s at the door, lets you talk to visitors remotely, and records video footage. But all of that depends on one thing: power.
Most Arlo doorbells use rechargeable or standard AA batteries. Depending on usage, these can last anywhere from 6 to 12 months. However, factors like extreme temperatures, frequent motion alerts, or poor Wi-Fi signal can drain them faster.
When the battery gets low, you’ll notice signs like:
– Delayed notifications
– Blurry or frozen video
– The doorbell not responding to button presses
– The Arlo app showing a low battery warning
Ignoring these signs can leave your home unprotected. That’s why regular battery checks and timely replacements are essential.
What You’ll Need
Before you begin, make sure you have the following items ready:
- New batteries: Arlo recommends using AA lithium batteries (like Energizer Ultimate Lithium) or high-quality NiMH rechargeable batteries (such as Eneloop). Avoid cheap alkaline batteries—they drain quickly and can leak.
- A clean, dry cloth: For wiping the battery compartment.
- Your smartphone or tablet: With the Arlo app installed and logged in.
- A stable Wi-Fi connection: So you can re-sync the doorbell after replacement.
- Optional: a small flashlight: To help see inside the battery compartment if lighting is poor.
Having everything ready will make the process faster and smoother.
Step 1: Check Battery Level in the Arlo App
Before you climb up to remove your doorbell, check the battery level in the Arlo app. This helps confirm that low power is the issue—and saves you time if the problem is something else.
Open the Arlo App
Launch the Arlo app on your phone or tablet. Make sure you’re logged into the correct account.
Select Your Doorbell
Tap on the camera icon for your doorbell. It should show a live view or the last recorded clip.
Check the Battery Icon
Look for a small battery icon near the top of the screen. It will show the current charge level:
– Green: Good (75–100%)
– Yellow: Low (25–74%)
– Red: Critical (below 25%)
If it’s red or yellow, it’s time for a change. If it’s green but the doorbell isn’t working, the issue might be Wi-Fi, settings, or hardware—not the battery.
Note the Battery Type
Check what type of batteries your model uses. Most Arlo doorbells use two AA batteries, but some older models may differ. Refer to your user manual or the Arlo support page if unsure.
Step 2: Power Off the Doorbell
Safety first! Before removing the doorbell, it’s best to power it off. This prevents accidental button presses, electrical shorts, or damage to the internal components.
Turn Off the Doorbell in the App
In the Arlo app, go to your doorbell’s settings. Look for an option like “Power Off” or “Disable Device.” Tap it to shut down the doorbell remotely.
Wait 10–15 Seconds
Give the device a moment to fully power down. You’ll know it’s off when the LED light (if visible) stops blinking.
Optional: Turn Off Wi-Fi Temporarily
If you’re concerned about interference, you can temporarily disable your home Wi-Fi. But this isn’t usually necessary.
Step 3: Remove the Arlo Doorbell from the Mount
Now it’s time to take the doorbell off the wall. Arlo doorbells are designed for easy removal—no screws or tools needed.
Locate the Release Tab
Look at the bottom edge of the doorbell. You’ll see a small plastic tab or lever. This is the release mechanism.
Press and Hold the Tab
Use your thumb to press and hold the release tab firmly. It may take a little pressure—don’t be afraid to push.
Slide the Doorbell Down
While holding the tab, gently slide the entire doorbell downward. It should come free from the mounting plate with a slight tug.
Set It Down Safely
Place the doorbell on a soft surface, like a towel or table. Avoid dropping it or exposing it to water.
Step 4: Open the Battery Compartment
With the doorbell removed, you can now access the battery compartment.
Find the Battery Cover
On the back of the doorbell, you’ll see a small rectangular cover. It’s usually held in place by a sliding latch or a small screw.
Slide or Unscrew the Cover
– For sliding covers: Push the latch in the direction indicated by the arrow (usually left or right).
– For screw covers: Use a small Phillips-head screwdriver to loosen the screw. Keep the screw in a safe place so you don’t lose it.
Lift Off the Cover
Once the latch is released, gently lift the cover away. You’ll now see the two AA battery slots.
Step 5: Remove the Old Batteries
Now it’s time to take out the old batteries.
Note the Battery Orientation
Look at how the old batteries are positioned. Most Arlo doorbells have a diagram inside the compartment showing the correct + and – alignment. Take a photo with your phone if you’re unsure—this helps when inserting the new ones.
Gently Push the Batteries Out
Use your fingers to push the batteries from the bottom edge. They should slide out easily. If they’re stuck, gently wiggle them side to side.
Dispose of Old Batteries Properly
Don’t throw old batteries in the trash. Take them to a recycling center or a store that accepts battery recycling (like Best Buy or Home Depot). Lithium and NiMH batteries contain materials that can harm the environment.
Step 6: Clean the Battery Compartment
Before inserting new batteries, take a moment to clean the compartment.
Wipe with a Dry Cloth
Use a clean, dry cloth to wipe away any dust, dirt, or moisture. Avoid using water or cleaning sprays—they can damage the electronics.
Check for Corrosion
Look for white or green powdery residue around the battery terminals. This is corrosion, and it can interfere with power flow. If you see it:
– Use a cotton swab dipped in vinegar or lemon juice to gently scrub the area.
– Wipe clean with a dry cloth.
– Let it dry completely before inserting new batteries.
Inspect the Contacts
Make sure the metal contacts inside the compartment are straight and not bent. If they’re misaligned, gently bend them back into place with tweezers.
Step 7: Insert the New Batteries
Now for the fun part—putting in the new batteries!
Choose the Right Batteries
Use only AA lithium or high-quality NiMH rechargeable batteries. Here’s why:
– Lithium batteries: Last longer (up to 12 months), perform well in cold weather, and don’t leak easily.
– NiMH rechargeables: Eco-friendly and cost-effective if you recharge them regularly. Look for low-self-discharge (LSD) types like Panasonic Eneloop.
Avoid alkaline batteries—they drain quickly and can leak, damaging your doorbell.
Insert with Correct Polarity
Match the + and – ends of the batteries to the diagram inside the compartment. Push them in firmly until they click into place.
Double-Check Alignment
Make sure both batteries are seated properly and facing the right direction. Incorrect installation can prevent the doorbell from powering on.
Step 8: Close the Battery Compartment
Once the new batteries are in, it’s time to seal everything up.
Replace the Cover
Slide or screw the battery cover back into place. Make sure it’s secure—loose covers can let in moisture.
Test the Seal
Give the cover a gentle tug to ensure it’s locked. If it moves, reattach it properly.
Step 9: Reattach the Doorbell to the Mount
Now that the batteries are in, it’s time to put the doorbell back on the wall.
Align the Doorbell with the Mount
Hold the doorbell so the grooves on the back align with the mounting plate on the wall.
Slide It Upward
Gently slide the doorbell upward until it clicks into place. You should feel it lock securely.
Press the Release Tab to Test
Press the release tab at the bottom. The doorbell should stay in place. If it falls off, reattach it and make sure it’s fully seated.
Step 10: Power On and Re-Sync the Doorbell
Your doorbell is back on the wall—now let’s get it working again.
Turn It Back On in the App
Open the Arlo app and go to your doorbell’s settings. Tap “Power On” or “Enable Device.”
Wait for the LED Light
The doorbell’s LED should blink blue, indicating it’s searching for a connection.
Re-Sync with the Base Station (if applicable)
If you have an Arlo base station:
– Press the sync button on the base station.
– Within 10 seconds, press and hold the doorbell’s button for 5 seconds until the LED blinks amber.
– Wait for the LED to turn solid green—this means it’s connected.
Check the Live View
Tap the live view in the Arlo app. You should see a clear video feed. Test the doorbell button to make sure it triggers a notification.
