Your Arlo Doorbell 2nd Generation is a battery-powered smart device designed to provide 24/7 surveillance, motion detection, and two-way audio. Unlike wired doorbells, it relies entirely on its rechargeable lithium-ion battery to function. That means regular charging is essential to maintain performance.
A fully charged battery ensures:
– Reliable motion alerts
– Clear video recordings
– Smooth live streaming
– Consistent Wi-Fi connectivity
Neglecting to charge your doorbell can lead to missed visitors, failed recordings, and frustration. Plus, improper charging habits—like using the wrong cable or charging in extreme temperatures—can shorten the battery’s lifespan.
By following the correct charging procedure, you’ll keep your Arlo doorbell working at its best and avoid unnecessary replacements or service calls.
What You’ll Need to Charge Your Arlo Doorbell
Before you begin, gather these essential items:
- Arlo Doorbell 2nd Generation – Obviously!
- Official Arlo charging cable – Included in the box; do not substitute
- USB power adapter – A standard 5V/1A or 5V/2A adapter works best
- Micro-USB to USB cable (if not using the Arlo cable) – Only if your Arlo cable is damaged (not recommended long-term)
- Phillips-head screwdriver or Arlo security screwdriver – For removing the mounting plate
- Clean, dry cloth – To wipe the doorbell and charging port
- Stable surface – A table or countertop to charge the device safely
Avoid using fast chargers, wireless chargers, or car chargers unless specifically rated for lithium-ion devices. These can overheat the battery and reduce its lifespan.
Step 1: Check the Battery Level
Before removing your doorbell, check its current battery level to confirm it needs charging.
How to Check Battery Status
There are two ways to check your Arlo doorbell’s battery:
1. Via the Arlo App:
– Open the Arlo app on your smartphone or tablet.
– Tap on your doorbell device.
– Look for the battery icon in the top-right corner of the live view screen.
– The icon shows a percentage (e.g., 20%, 50%, 100%).
2. Using the Doorbell LED Light:
– Press the doorbell button.
– Observe the LED ring:
– Blinking red: Low battery (below 20%) – charge immediately.
– Solid green: Fully charged.
– Blinking green: Charging in progress.
– Solid red: Error or malfunction.
If the battery is below 20%, it’s time to charge. Don’t wait until it dies completely—this can stress the battery.
Step 2: Safely Remove the Arlo Doorbell
Now that you’ve confirmed the battery is low, it’s time to remove the doorbell from the wall.
Turn Off Power (If Hardwired)
Even though the Arlo Doorbell 2nd Generation is battery-powered, some users install it with existing doorbell wiring for backup power. If you’ve connected it to wires:
– Turn off the power at your home’s circuit breaker.
– Use a non-contact voltage tester to confirm no electricity is flowing.
– This prevents accidental shocks or short circuits.
Remove the Mounting Plate
The doorbell is secured to a mounting plate with a security screw. Here’s how to remove it:
1. Locate the small security screw at the bottom of the doorbell.
2. Use the Arlo security screwdriver (included) or a compatible Phillips-head screwdriver.
3. Turn the screw counterclockwise until it’s loose.
4. Gently pull the doorbell away from the mounting plate.
Tip: Hold the doorbell with one hand while unscrewing to prevent it from falling.
Detach the Doorbell
Once the screw is removed, the doorbell should slide out easily. Be careful not to pull too hard—there may still be a wire connected if you’ve hardwired it.
If you’ve connected wires:
– Disconnect the wire terminals by loosening the screws.
– Label the wires (e.g., “Front,” “Transformer”) so you can reconnect them later.
Place the doorbell on a soft surface to avoid scratching the lens or casing.
Step 3: Clean the Charging Port
Before plugging in the charger, inspect the charging port on the back of the doorbell.
Why Cleaning Matters
Dust, dirt, or moisture in the charging port can:
– Prevent a secure connection
– Cause charging interruptions
– Lead to corrosion over time
How to Clean the Port
1. Use a dry, soft cloth to wipe the exterior.
2. Gently insert a cotton swab into the micro-USB port to remove debris.
3. Avoid using water, alcohol, or compressed air—these can damage internal components.
4. Let the port air-dry completely before charging.
A clean port ensures a stable connection and faster, safer charging.
Step 4: Connect the Charging Cable
Now it’s time to plug in your Arlo doorbell.
Use the Official Arlo Cable
The Arlo Doorbell 2nd Generation comes with a custom micro-USB charging cable. This cable is designed specifically for the device and ensures optimal charging speed and safety.
Do not use:
– Third-party micro-USB cables (they may not deliver consistent power)
– USB-C cables (incompatible)
– Damaged or frayed cables
Plug In the Cable
1. Insert the micro-USB end into the charging port on the back of the doorbell.
2. Make sure it’s fully seated—listen for a slight click.
3. Connect the USB end to a power adapter.
4. Plug the adapter into a wall outlet.
Recommended Power Sources:
– Wall outlet (best option)
– Computer USB port (slower charging)
– Power bank (for portability)
Avoid using:
– Car chargers (voltage fluctuations)
– Fast chargers (can overheat battery)
– Extension cords with multiple devices (may reduce power)
Step 5: Monitor the Charging Process
Once connected, your doorbell will begin charging. Here’s what to expect:
LED Indicators During Charging
– Blinking green light: Charging in progress.
– Solid green light: Fully charged.
– Blinking red light: Low battery or charging error.
– No light: Cable not connected or power issue.
How Long Does It Take to Charge?
Charging time depends on the current battery level and power source:
– From 0% to 100%: 4–6 hours (with official cable and wall adapter)
– From 20% to 100%: 2–3 hours
– Using a computer USB port: Add 1–2 hours
Tip: Charge overnight for best results. Avoid unplugging before it’s fully charged.
Can You Overcharge the Battery?
No. The Arlo Doorbell 2nd Generation has built-in battery management that stops charging when full. You can leave it plugged in overnight without risk.
However, avoid leaving it connected for days at a time—this can slightly reduce long-term battery health.
Step 6: Reinstall the Doorbell
Once fully charged, it’s time to put your doorbell back.
Reconnect Wires (If Applicable)
If you disconnected wires during removal:
1. Reattach the wires to the terminals on the mounting plate.
2. Tighten the screws securely.
3. Ensure no bare wire is exposed.
Mount the Doorbell
1. Align the doorbell with the mounting plate.
2. Slide it into place until it clicks.
3. Insert the security screw and tighten it clockwise.
4. Do not overtighten—this can crack the casing.
Test the Installation
– Press the doorbell button.
– Check the LED light (should be solid green).
– Open the Arlo app and verify the device is online.
– Test motion detection by walking in front of the doorbell.
If the doorbell doesn’t respond, double-check the screw and wire connections.
Tips to Extend Battery Life
Charging is only part of the equation. To maximize battery life between charges, follow these best practices:
Adjust Motion Settings
– Reduce motion sensitivity in the Arlo app.
– Set activity zones to ignore areas like busy streets or trees.
– Lower recording length (e.g., 15 seconds instead of 30).
Optimize Video Quality
– Use “Standard” instead of “HD” video quality.
– Disable night vision if not needed (or use “Auto” mode).
Limit Live Streaming
– Avoid frequent live views—each session drains the battery.
– Use motion alerts to trigger recordings instead.
Protect from Extreme Weather
– Install under an eave or awning to shield from rain and snow.
– Avoid direct sunlight in summer—heat degrades batteries.
– In cold climates, charge more frequently (battery drains faster below 32°F/0°C).
Enable Battery Saver Mode
In the Arlo app:
– Go to Device Settings > Power Management.
– Turn on “Battery Saver” to reduce background activity.
Troubleshooting Common Charging Issues
Even with proper care, you might encounter problems. Here’s how to fix them:
Doorbell Won’t Charge
Possible Causes:
– Faulty cable
– Dirty charging port
– Dead power adapter
– Battery failure
Solutions:
1. Try a different USB cable (preferably the official one).
2. Clean the charging port.
3. Test the power adapter with another device.
4. Contact Arlo support if the battery won’t hold a charge.
LED Light Not Turning On
Possible Causes:
– Loose connection
– Damaged LED
– Software glitch
Solutions:
1. Unplug and reconnect the cable.
2. Restart the doorbell by holding the button for 10 seconds.
