Understanding Your Blink Doorbell Model

Before you begin charging, it’s important to know which Blink doorbell model you have. Blink offers several doorbell models, and their charging methods vary slightly. The two main types are:

• Blink Video Doorbell (2nd Gen): Uses two AA non-rechargeable lithium batteries. These are not meant to be recharged—replace them when they run out.
• Blink Video Doorbell (3rd Gen) and newer: Features a built-in rechargeable lithium-ion battery. This battery can be charged via USB.

Knowing your model helps you choose the right charging method. For example, if you have a 2nd Gen doorbell, you won’t be charging the batteries—you’ll replace them. But if you have a 3rd Gen or newer, you’ll need to remove the doorbell and charge it via USB.

To check your model, open the Blink app, go to Devices, select your doorbell, and look under Device Info. You’ll see the model number listed there.

Step-by-Step: How to Charge Blink Doorbell (3rd Gen and Newer)

If you have a Blink doorbell with a built-in rechargeable battery, follow these steps to charge it safely and effectively.

Gather Your Charging Equipment

Before you start, make sure you have the following:

• The included USB cable (usually USB-A to micro-USB or USB-C)
• A compatible power source (wall adapter, computer USB port, or power bank)
• A small Phillips-head screwdriver (if your model requires it)
• A clean, dry workspace

Using the original cable ensures compatibility and reduces the risk of overheating or damage. Avoid cheap third-party cables, as they may not deliver the correct voltage.

Turn Off the Doorbell (Optional but Recommended)

While not always required, turning off your doorbell before charging can prevent accidental triggers or app notifications during the process. To do this:

1. Open the Blink app.
2. Tap on your doorbell device.
3. Tap the power icon to turn it off.

This step is optional, but it can help avoid confusion while the doorbell is disconnected.

Remove the Doorbell from the Mount

Now it’s time to safely detach your doorbell from the wall mount. Follow these steps carefully to avoid damaging the device or injuring yourself.

Step 1: Locate the Release Tab

Most Blink doorbells have a small release tab on the bottom edge of the device. This tab is usually a small plastic lever or button. Gently press or slide it upward or outward.

Step 2: Lift the Doorbell Off

Once the tab is released, carefully lift the doorbell straight up and away from the mount. The device should come off easily—don’t force it. If it feels stuck, double-check that the release tab is fully engaged.

Step 3: Disconnect the Mount (If Needed)

Some models allow you to leave the mount on the wall and just remove the doorbell. Others may require you to unscrew the entire mount. Refer to your user manual if you’re unsure.

Connect the USB Cable

Now that the doorbell is removed, it’s time to charge it.

Step 1: Locate the Charging Port

On most Blink doorbells, the charging port is on the back or bottom edge of the device. It’s usually a micro-USB or USB-C port. Look for a small rubber cover—this protects the port from dust and moisture.

Step 2: Open the Port Cover

Gently lift the rubber cover to expose the charging port. Be careful not to tear it—this cover helps keep the port clean and dry.

Step 3: Plug in the Cable

Insert the USB cable into the charging port. Make sure it’s fully seated. Then plug the other end into your power source.

Choose the Right Power Source

Not all USB power sources are created equal. For best results, use one of the following:

• Wall adapter: A 5V/1A or 5V/2A USB wall charger (like the one that came with your phone).
• Computer USB port: A standard USB port on a laptop or desktop.
• Power bank: A portable battery pack with USB output.

Avoid using fast chargers or high-voltage adapters unless specified by Blink. Overcharging or using incorrect voltage can damage the battery.

Monitor the Charging Process

Once connected, your doorbell will begin charging. Here’s what to expect:

• The LED light on the front of the doorbell may flash or glow red/orange during charging.
• A full charge typically takes 2 to 4 hours, depending on the battery level and power source.
• When fully charged, the LED may turn solid green or stop flashing.

You can also check the battery level in the Blink app. Go to Devices, select your doorbell, and look at the battery icon. It will show a percentage or a battery bar.

Reinstall the Doorbell

After charging, it’s time to put your doorbell back in place.

Step 1: Disconnect the Cable

Unplug the USB cable from the doorbell and close the rubber port cover. Make sure it’s sealed properly to protect against moisture.

Step 2: Align with the Mount

Hold the doorbell so the back aligns with the wall mount. The charging contacts (if applicable) should line up with the mount’s connectors.

Step 3: Slide into Place

Gently slide the doorbell down onto the mount until you hear a click. The release tab should lock into place.

Step 4: Test the Connection

Open the Blink app and check if the doorbell is online. Tap the live view button to confirm it’s working. You should also receive a motion alert if someone walks by.

Charging Blink Doorbell with AA Batteries (2nd Gen)

If you have a Blink Video Doorbell (2nd Gen), it uses two AA non-rechargeable lithium batteries. These batteries are not meant to be recharged—doing so can be dangerous and may damage the device.

When to Replace the Batteries

You’ll know it’s time to replace the batteries when:

• The Blink app shows a low battery warning.
• The doorbell stops sending alerts or recording clips.
• The LED light doesn’t turn on when motion is detected.

Blink recommends using lithium AA batteries for longer life and better performance in extreme temperatures. Alkaline batteries may work but drain faster.

How to Replace the Batteries

Follow these steps to safely replace the batteries:

Step 1: Remove the Doorbell

Use the same method described earlier—press the release tab and lift the doorbell off the mount.

Step 2: Open the Battery Compartment

On the back of the doorbell, locate the battery compartment. It’s usually held in place by a small screw. Use a Phillips-head screwdriver to remove it.

Step 3: Remove Old Batteries

Carefully take out the old batteries. Dispose of them properly—lithium batteries should be recycled at an electronics or battery recycling center.

Step 4: Insert New Batteries

Insert two new AA lithium batteries, making sure the positive (+) and negative (-) ends match the markings inside the compartment.

Step 5: Close the Compartment

Replace the cover and tighten the screw securely. Don’t overtighten—this can strip the screw or crack the plastic.

Step 6: Reinstall the Doorbell

Slide the doorbell back onto the mount until it clicks into place. Test it using the Blink app.

Tips to Extend Battery Life

Charging your Blink doorbell regularly is important, but you can also take steps to make the battery last longer between charges. Here are some practical tips:

Adjust Motion Sensitivity

High motion sensitivity means your doorbell detects even small movements, like leaves blowing or pets walking by. This can trigger frequent recordings and drain the battery.

To reduce unnecessary alerts:

• Open the Blink app.
• Go to your doorbell settings.
• Tap Motion Settings.
• Lower the sensitivity slider to “Low” or “Medium.”

You can also set up Motion Zones to focus on specific areas, like your front walkway, and ignore others, like the street.

Shorten Clip Length

By default, Blink doorbells record 15- or 30-second clips. Longer clips use more power.

To save battery:

• Go to Device Settings in the app.
• Tap Clip Length.
• Choose a shorter duration, like 10 seconds.

This small change can significantly extend battery life.

Disable the LED Light

The LED light on your doorbell helps you see it at night, but it also uses power. If you don’t need it, you can turn it off.

To disable the LED:

• Go to Device Settings.
• Tap LED Settings.
• Toggle off Motion LED and Status LED.

Note: This may reduce visibility at night, so only disable it if you’re okay with a darker doorbell.

Use Scheduled Armed Mode

Instead of leaving your doorbell armed 24/7, set it to only record during certain hours.

To schedule armed mode:

• Go to Device Settings.
• Tap Armed Schedule.
• Set times when the doorbell should be active (e.g., 7 PM to 7 AM).

This reduces unnecessary recordings and saves battery.

Avoid Extreme Temperatures

Blink doorbells are designed to work in temperatures from -4°F to 113°F (-20°C to 45°C). But extreme cold or heat can reduce battery life.

If possible:

• Avoid installing the doorbell in direct sunlight or near heaters.
• In winter, consider bringing the doorbell indoors during severe cold snaps (if your model allows).

Troubleshooting Common Charging Issues

Sometimes, your Blink doorbell may not charge properly. Here are some common problems and how to fix them.

Doorbell Won’t Charge

If your doorbell isn’t charging, try these steps:

• Check the cable: Try a different USB cable. The original cable may be damaged.
• Try a different power source: Plug into a wall adapter instead of a computer, or vice versa.
• Inspect the charging port: Look for dust, lint, or damage. Use a can of compressed air to clean it gently.
• Restart the doorbell: Remove it from the mount, wait 10 seconds, then reconnect and try charging again.

Battery Drains Too Fast

If your battery dies quickly even after charging, consider:

• Too many motion alerts: Adjust sensitivity or motion zones.
• Weak Wi-Fi signal: A poor connection forces the doorbell to work harder. Move your router closer or use a Wi-Fi extender.
• Old battery: Rechargeable batteries lose capacity over time. If your doorbell is more than 2–3 years old, the battery may need replacing.

Doorbell Won’t Turn On After Charging

If the doorbell doesn’t power on after charging:

• Make sure it’s fully charged (wait at least 4 hours).
• Try a hard reset: Remove the battery (if removable) or hold the reset button for 20 seconds.
• Reinstall the doorbell and check the app for errors.

App Shows “Low Battery” Even After Charging

This could mean:

• The battery isn’t fully charged—wait longer.
• The battery is faulty—contact Blink support for a replacement.
• The app needs refreshing—close and reopen the app or restart your phone.
