How Many Batteries for Blink Camera?

Hey there! If you’re curious about how many batteries you need for your Blink camera and how to make them last, you’ve come to the right place. Blink cameras, known for their convenience and ease of use, primarily require AA lithium non-rechargeable batteries to keep them running smoothly. Specifically, models like the Blink Outdoor 4 require two AA 1.5V lithium metal batteries to operate​​​​.

How Many Batteries Do You Need?

Each Blink camera needs two AA batteries to function. These batteries are designed to last up to two years under default settings, but actual battery life can vary based on several factors, including device settings, usage patterns, and environmental conditions​​​​.

Factors Affecting Battery Life

Several factors can influence how long your batteries last:

  • Type of Batteries: Using the recommended Energizer Ultimate size AA 1.5 volt Lithium non-rechargeable batteries, or an equivalent, is crucial for optimal performance​​.
  • Environmental Conditions: Extreme temperatures can affect battery performance​​.
  • Wi-Fi and Device Signal Strength: Weak signals between your camera, Wi-Fi network, and Sync Module can increase battery consumption​​.

Maximizing Battery Life

To extend your Blink camera’s battery life, consider adjusting the camera’s settings:

  • Motion Detection Settings: Fine-tuning these can reduce unnecessary alerts and save battery life.
  • Camera Usage: Limiting Live View sessions and turning off the camera when not needed can help conserve battery power.

Battery Replacement and Monitoring

When it’s time to replace your batteries, the Blink app will let you know by indicating a “Needs Replacement” status under the battery strength section in Device Settings. Plus, it will alert you with a “High Usage” message if your camera settings might cause higher-than-normal battery consumption​​.


By understanding the correct type of batteries your Blink camera needs and how to optimize settings for longer life, you’ll enjoy uninterrupted service and peace of mind. Remember, regular checks on battery status through the Blink app and mindful usage can greatly extend the time between replacements, ensuring your Blink camera is always ready to capture what matters most.

Stay informed and get the most out of your Blink camera by keeping these tips in mind. Happy monitoring!

They gave me a quote on solar panel installation in my Lekki home and I was wowed by their professionalism. I recommend them to my friends now too.

They are the best solar company in Lagos, Nigeria for a reason. I enjoyed every bit of time spent working with them at my brothers Banana Island home. Absolutely the best!
