Before we dive into charging, let’s talk about how your Blink doorbell gets its power. Most Blink doorbells—including the Blink Video Doorbell and the Blink Video Doorbell with Sync Module 2—are designed to run on removable AA batteries. These are typically lithium or rechargeable NiMH batteries, depending on what you’ve installed.
Unlike traditional doorbells that connect to your home’s electrical wiring, Blink doorbells are wireless and battery-operated. This makes installation quick and easy, especially if you don’t have existing doorbell wiring. But it also means you’ll need to monitor battery life and recharge when needed.
The good news? Blink doorbells are built for efficiency. With normal use, a set of high-quality batteries can last 6 to 12 months. That said, factors like frequent motion detection, extreme temperatures, and high video quality settings can drain the battery faster.
Types of Batteries Used in Blink Doorbells
Blink recommends using AA lithium batteries for the best performance and longest life. These are non-rechargeable but offer excellent longevity—especially in cold weather. If you prefer rechargeable options, you can use AA NiMH (Nickel-Metal Hydride) batteries, but they may need more frequent charging.
Some users opt for third-party rechargeable battery packs designed specifically for Blink devices. These often come with built-in USB charging ports and can be more convenient than swapping individual AA batteries. Just make sure any third-party product is compatible and safe to use.
How the Blink App Helps Monitor Battery Life
One of the best features of the Blink system is the app. The Blink app (available for iOS and Android) gives you real-time updates on your doorbell’s battery level. You’ll see a battery icon in the device status section, and the app will send you a push notification when the battery drops below 20%.
This early warning system gives you plenty of time to plan a recharge before your doorbell stops working. You can also check battery history in the app to see how quickly it’s draining and adjust settings accordingly.
Step 1: Check Your Blink Doorbell’s Battery Level
The first step in charging your Blink doorbell is knowing when it needs a charge. You don’t want to wait until it dies completely—especially if you’re expecting guests or deliveries.
Open the Blink App
Start by opening the Blink app on your smartphone or tablet. Make sure you’re logged into the account associated with your doorbell.
Navigate to Your Device
Tap on the “Devices” tab at the bottom of the screen. You’ll see a list of all your Blink cameras and doorbells. Select the doorbell you want to check.
View Battery Status
On the device screen, look for the battery icon near the top. It will show a percentage (e.g., 45%) or a visual bar indicating how much charge is left. If the icon is red or flashing, it’s time to charge.
You can also go to “Device Settings” > “System Health” to see detailed battery information, including voltage and temperature.
Set Up Low Battery Alerts
To avoid surprises, make sure low battery notifications are enabled. Go to “Settings” > “Notifications” and toggle on “Low Battery Alerts.” This way, you’ll get a reminder before the battery gets too low.
Step 2: Remove the Battery from Your Blink Doorbell
Once you’ve confirmed the battery is low, it’s time to remove it for charging. This process is simple, but it’s important to do it carefully to avoid damaging the device.
Turn Off the Device (Optional but Recommended)
While not always necessary, turning off your Blink doorbell before removing the battery can prevent accidental triggers or errors. In the app, go to your doorbell’s settings and toggle “Device Power” to off.
Locate the Battery Compartment
Your Blink doorbell has a small compartment on the back or bottom, depending on the model. It’s usually secured with a small screw or a sliding latch.
For most models, you’ll need a Phillips-head screwdriver to remove the screw. Keep the screw in a safe place—you’ll need it to reattach the compartment later.
Open the Battery Compartment
Unscrew the compartment cover and gently pull it away from the doorbell. Inside, you’ll see the AA batteries (or battery pack) seated in place.
Remove the Batteries
Carefully lift the batteries out of the compartment. If you’re using a rechargeable battery pack, disconnect it from the internal connector by gently pulling the plug.
Be gentle—don’t force anything. The connectors are designed to be removable, but rough handling can damage the wires.
Inspect for Damage
While the battery is out, take a quick look inside the compartment. Check for corrosion, dirt, or moisture. If you see any, clean it with a dry cloth or cotton swab. Never use water or cleaning liquids near the electronics.
Step 3: Charge the Battery
Now that the battery is out, it’s time to charge it. How you charge it depends on the type of battery you’re using.
Charging AA Lithium Batteries
If you’re using standard AA lithium batteries (non-rechargeable), you don’t actually “charge” them—you replace them with fresh ones. Blink recommends using lithium batteries because they last longer and perform better in cold weather.
Simply insert new AA lithium batteries into the compartment, making sure the positive (+) and negative (-) ends match the markings inside.
Charging Rechargeable AA Batteries
If you’re using rechargeable NiMH AA batteries, you’ll need a compatible battery charger. Place the batteries in the charger according to the manufacturer’s instructions.
Most chargers take 2 to 4 hours to fully charge a set of AA batteries. Avoid overcharging—some smart chargers will automatically stop when full, but it’s still best to unplug them once charged.
Charging a Rechargeable Battery Pack
If you’re using a third-party rechargeable battery pack (like the Blink OutDoor Rechargeable Battery Pack), charging is even easier. These packs usually have a built-in USB port.
Simply connect the included USB cable to the pack and plug the other end into a USB power source—like a wall adapter, computer, or power bank.
A small LED light on the pack will usually indicate charging status: red for charging, green for fully charged.
Use the Right Charger
Always use a high-quality USB charger with the correct output. Blink recommends using a 5V/1A or 5V/2A charger. Avoid cheap or damaged chargers, as they can damage the battery or cause overheating.
Charging Time Expectations
Here’s a quick reference for charging times:
– AA NiMH batteries: 2–4 hours
– Rechargeable battery pack: 2–3 hours
– New lithium batteries: No charging needed—just install
Don’t rush the process. Let the battery charge fully before reinstalling.
Step 4: Reinstall the Battery and Doorbell
Once the battery is fully charged (or you’ve installed fresh batteries), it’s time to put everything back together.
Insert the Battery
Place the charged battery or battery pack back into the compartment. Make sure it’s seated properly and the connector is fully plugged in (if applicable).
Double-check the orientation—batteries must go in the correct direction to work.
Close the Battery Compartment
Slide or screw the compartment cover back into place. If you removed a screw, tighten it securely—but don’t over-tighten, as this can strip the plastic.
Make sure the cover is flush with the doorbell body to prevent water from getting in.
Reattach the Doorbell to the Mount
Hold the doorbell against the mounting plate on your wall. Align the bottom first, then press the top until it clicks into place.
Give it a gentle tug to make sure it’s secure. A loose doorbell can fall or malfunction.
Turn the Device Back On
If you turned off the device earlier, go back into the Blink app and toggle “Device Power” back on.
Wait a few seconds for the doorbell to reconnect to your Wi-Fi and Sync Module (if used).
Test the Doorbell
Press the button on your doorbell to test it. You should see a light flash and receive a notification on your phone.
You can also open the live view in the app to confirm the camera is working and the battery level is updating.
Tips to Extend Your Blink Doorbell’s Battery Life
Charging your Blink doorbell is easy, but wouldn’t it be better if you didn’t have to do it so often? Here are some practical tips to help your battery last longer.
Adjust Motion Detection Settings
Frequent motion alerts can drain the battery quickly. In the Blink app, go to your doorbell’s settings and reduce the motion sensitivity. You can also set activity zones to ignore areas like busy streets or trees.
Shorten Video Clip Length
By default, Blink records 10-second clips. You can reduce this to 5 seconds in the app under “Clip Length.” Shorter clips use less power.
Disable Unnecessary Features
Features like infrared night vision, two-way audio, and live view use extra power. Only enable them when needed.
Use a Sync Module
If you have multiple Blink devices, using a Sync Module 2 can improve efficiency. It reduces the number of direct Wi-Fi connections, which helps save battery life.
Keep the Doorbell Clean
Dirt, snow, or ice on the lens or sensors can cause false motion alerts. Wipe the doorbell with a soft, dry cloth regularly to keep it clean.
Avoid Extreme Temperatures
Blink doorbells work best between -4°F and 113°F (-20°C to 45°C). Extreme cold can reduce battery life, so consider using lithium batteries in winter.
