Do Blink Doorbells Need Batteries?

Last Updated Jul 21, 2022

Having permanent power for any devices you’ve installed in your home is certainly more convenient than having them run on battery power. You are installing a Blink Doorbell, which has a battery slot along with wire connections. You are now wondering: do Blink Doorbells need batteries to run?

Blink Doorbells require two 1.5V Lithium AA batteries to operate. The wire connections you see are primarily for attaching your doorbell to a chime box. It’s important to only use lithium batteries, as others can lead to malfunctions and operating problems that negatively affect battery life.

Making sure your Blink Doorbell operates under optimal conditions will increase its battery life, giving you some extra time before you need to replace them. Keep reading to learn more about the Blink Doorbell’s battery power and how to ensure the longest lifespan!

Do Blink Doorbells Need Batteries?

You might have noticed that the Blink Doorbells have two wire connections at the back. These connections are intended to connect the doorbell to the chime in your home. When the doorbell button is pressed, your in-home chime will ring. 

However, the wiring does not supply sufficient power to run all the smart doorbell features. For this reason, it needs batteries to operate. 

Blink Doorbell runs on two 1.5V AA batteries, but not any batteries will work. Blink only recommends using 1.5V Lithium AA batteries. Using alkaline or rechargeable lithium-ion batteries is not recommended, as these batteries will not provide enough power and often have a much lower lifespan than their lithium counterparts. 

According to Blink statistics, the average user activates their Blink Doorbell, whether through Live View, two-way talk, or motion-activated recording, for a total of about 70 seconds per day. Under optimal operating conditions, the batteries should last two years at this rate. 

However, extreme temperatures, a slow internet connection, or a poor WiFi signal can greatly affect battery life. Below, we will look at how to avoid these poor operating conditions and some limits you should operate within. 

Extreme Temperatures

Extremely hot or cold temperatures can significantly reduce battery life. Lithium 1.5V AA batteries have an operating range between -40 degrees Celcius to 55 degrees Celcius (-40 to 130 degrees Fahrenheit), but the extremes are not recommended. 

These batteries should operate normally down to about -17 degrees Celcius (0 degrees Fahrenheit), but their useful life will decrease by 60% anywhere below that. If the climate allows, try keeping them warmer than that. 

Regarding heat, the batteries will operate at their best capacity at around 30 degrees Celcius (85 degrees Fahrenheit). Anything hotter will cause performance-related issues and a shorter battery lifespan.

If you are storing extra batteries for later replacement, Blink recommends storing them around 15 degrees Celcius (59 degrees Fahrenheit). Avoid leaving them in your car or other non-climate controlled areas, such as a shed or garage.

A Slow Internet Connection or Poor WiFi Signal

A slower internet connection will require your Blink Doorbell to work harder, thus using more battery power. For the best operation, ensure your internet plan allows for an upload speed of at least 2 Mbps. 

If you’re experiencing a slow internet speed, there are several steps you can take to improve the signal. These include:

  • Move the router closer: Blink Doorbells are located outside exterior walls, so if the router is too far away, you may experience a slow connection or poor signal. Move it closer to the front door to obtain a better signal. 
  • Get a WiFi Extender: If moving the router is not an option, consider placing a WiFi extender between the router and the Blink Doorbell. 
  • Use a 2.4GHz frequency: Most routers allow users to switch between 2.4GHz and 5GHz frequencies. Make sure you are using the 2.4GHz WiFi frequency, as Blink devices cannot connect to 5GHz.

Having too many Blink devices connected to the same network or having a poor connection between your router and Blink Doorbell can drain your battery faster. Make sure your network can handle all your devices and that you have a strong WiFi signal to avoid battery-related issues.

How to Check the Battery Status of Your Blink Doorbell

Throughout the expected two-year battery life, you can check the battery status of your Blink Doorbell through the Blink app. Simply click on the camera settings (the icon with three horizontal lines and a circle located on the camera thumbnail) and look for “Battery.” 

The status will either say “OK” or “Needs Replacement.” This will help you keep better track of how soon you can expect a battery change. 

Wrapping Up

Blink Doorbells require two 1.5V Lithium AA batteries. Your first set will be included in your doorbell package and give you around two years of battery life, as long as you keep the doorbell and batteries under optimal operating conditions.
