The beauty of this home security device lies ground in the interplay between its battery and hardwire features. Accurate details about this will help dispel any myths, and that’s precisely what I’m here for.

Let’s dive into the actual mechanics of your Blink Doorbell to answer this intriguing question. Trust me, you’re not alone if you find this confusing, but I promise we’ll clarify it together as you read on.

Does Blink Doorbell need a battery if hardwired?

Yes. Despite being hardwired, a Blink Doorbell indeed requires a battery. Even if connected to your doorbell wiring, this device uses the battery as its primary power source. The hardwire connection only helps utilize your pre-existing doorbell chime.

This misconception may stem from misunderstanding the term “hardwired”. Despite sounding like it means the device is plugged into a constant power supply, it refers only to the connection with your home’s doorbell system.

For example, a user named ‘vtchopperdude’ shared on Reddit that the low battery icon appeared on their app for their hardwired Blink Doorbell, creating confusion regarding the necessity of the battery.

How does the Blink wired doorbell work?

The Blink wired doorbell gives your home added security with its two-way talk, HD video, and motion detection features.

Even when it’s hardwired, it’s vital to know that the doorbell still requires two AA, 1.5-volt lithium non-rechargeable batteries for its operation. When someone presses the doorbell button, your wired functional chime rings.

The doorbell can be installed with the existing 16 to 24-volt AC wiring in your home, compatible with most mechanical or digital chimes. Moreover, by connecting it with a Sync Module, you could extend the battery life up to 2 years under normal usage.

Please note that even when wired, the doorbell’s functionality can further be expanded when combined with a Blink Subscription Plan, offering numerous features like Live View sessions, in-app sharing, and cloud storage among others.

The concept of a hardwired doorbell typically implies that it is connected to your home’s existing electrical system, providing a continuous power supply. In this case, a battery may not be necessary for the doorbell to function.

However, it’s important to note that some hardwired doorbells still have a battery backup option for added convenience and peace of mind.

So, while a battery may not be essential, it can serve as a backup power source in case of any electrical disruptions.


Can Blink camera work without battery?

Yes, a Blink camera can work without a battery. However, it’s important to note that while you can hardwire the camera to a power source using a USB cable, keeping the batteries in provides a backup in case of power outages.

For example, if you mount your Blink camera outdoors, a sudden power failure won’t affect its operation if batteries are in place. I’d recommend routinely testing your batteries, particularly if you’re depending on them as a backup.

Why blink doorbell wired still need battery?

The issue at hand is understanding why the Blink Doorbell, even when hardwired, still needs a battery. The simple explanation is that the doorbell’s critical functions run off the batteries, not the wiring. The Blink Doorbell lacks an internal power converter, and hence it continuously operates off batteries, regardless of any hardwiring.

Meanwhile, the hardwiring only powers the chime, your conventional physical bell. Additionally, being wired allows the Doorbell to use some of the current to stay online and conserve battery life.

Can Blink Doorbells Work Without Batteries?

No, the Blink Doorbell cannot operate without batteries. Even when the doorbell is hardwired, it runs off batteries, not the wiring. The hardwiring merely helps to keep the device online and listen for commands. The doorbell’s essential functions are battery-powered, ensuring consistent operation, regardless of fluctuations in power supply. Hence, if the batteries were removed, the device would cease to function.
