Replace the battery in under five minutes with these steps

Changing a Blink camera battery takes about five minutes and requires no tools. Open the camera's back panel, slide out the old battery, and insert two new AA batteries with the positive ends facing the correct direction. The camera will restart automatically once you close the panel, and you'll see a blue light confirming it's powered on.

Most Blink cameras use two AA batteries, though some older models use AAA. Check your camera's model number on the back of the device or in the Blink app under device settings if you're unsure which size you need. Alkaline batteries typically last 18 to 24 months depending on how often the camera records.

Key Takeaways

  • Blink cameras use either two AA or two AAA alkaline batteries, depending on the model—check your device before buying replacements.
  • The battery compartment is on the back of the camera and opens by sliding or unclipping a small panel with no screws required.
  • Insert new batteries with the positive (+) end facing toward the spring inside the compartment, or the camera won't power on.
  • The camera will restart and show a blue light when the new batteries are installed correctly and the panel is closed.
  • Alkaline batteries last longer than rechargeable ones in Blink cameras, so standard AA or AAA alkaline batteries are the better choice.

Locate the battery compartment on the back of your camera

The battery door is a small rectangular panel on the back of your Blink camera. On most models, you'll see a thin seam running horizontally across the back panel. The door slides downward or unclips with gentle pressure—there are no screws to remove.

If you're having trouble finding it, look for a small indentation or ridge you can grip with your fingernail. Push or slide in the direction the seam suggests (usually down), and the panel will come free. Set it aside somewhere you won't lose it.

Remove the old batteries and note their orientation

Inside the compartment, you'll see two battery slots side by side. Each slot has a metal spring at one end. The old batteries should slide out easily—if they're stuck, gently wiggle them side to side while pulling.

Before you remove them, notice which end of each battery is facing the spring. The positive end (marked with a +) should be pointing toward the spring. This orientation matters for the new batteries, so take a mental note or snap a quick photo with your phone if you're unsure.

Insert two new AA or AAA alkaline batteries

Check your camera's model to confirm whether it uses AA or AAA batteries. The battery compartment is sized for one or the other, so the wrong size won't fit. Blink Outdoor, Blink Indoor, and Blink Mini all use AA batteries. Blink XT2 and some older models use AAA.

Slide each new battery into its slot with the positive (+) end facing the spring, just like the old batteries were oriented. Push gently until the battery sits flat and makes contact with the spring. You should feel a slight click or resistance as it seats properly.

Alkaline batteries (like Duracell or Energizer) work better in Blink cameras than rechargeable NiMH batteries. Rechargeable batteries have a lower voltage and may cause the camera to report a low battery warning even when they're fully charged.

Close the battery compartment and confirm the camera powers on

Slide or clip the battery door back into place until it sits flush with the back of the camera. You should hear or feel a small click when it's fully seated. Don't force it—if it's not sliding smoothly, check that the batteries are seated correctly and try again.

Within a few seconds, you should see a blue light on the front of the camera. This light confirms the camera has power and is connecting to your network. If you see a red light or no light at all, open the compartment again and check that both batteries are inserted with the positive end toward the spring.

Check the battery status in the Blink app

Open the Blink app on your phone and tap the camera you just replaced batteries in. Go to the device settings or info screen—the exact location varies slightly by app version, but it's usually labeled "Device Health" or "Settings."

You should see the battery status listed as "Good" or showing a percentage. If it still shows "Low," wait a few minutes for the app to refresh, then check again. Sometimes the app takes a moment to recognize new batteries.

If the status doesn't improve after five minutes, remove the batteries, wait 30 seconds, and reinsert them. Make sure the positive ends are facing the springs. If the problem persists, one of the new batteries may be defective—try replacing just one battery at a time to identify which one is the issue.

Troubleshooting if the camera won't power on

If you don't see a blue light after closing the battery door, the most common cause is incorrect battery orientation. Open the compartment and double-check that the positive (+) end of each battery is pointing toward the metal spring. Even one battery installed backward will prevent the camera from powering on.

The second most common issue is a dirty battery contact. If the springs or metal contacts inside the compartment look corroded or discolored, gently wipe them with a dry cloth or a pencil eraser. Corrosion can prevent good electrical contact even with new batteries.

If you've checked orientation and cleaned the contacts and the camera still won't power on, try a different brand of alkaline batteries. Occasionally a battery from a new pack is defective. If the camera powers on with different batteries, the original pair was likely faulty.

Frequently Asked Questions

How often do I need to change the batteries?

Alkaline AA or AAA batteries typically last 18 to 24 months in a Blink camera, depending on how often the camera records motion events. Cameras that record frequently will drain batteries faster than cameras in low-activity areas. The Blink app will notify you when the battery status drops to "Low."

Can I use rechargeable batteries in my Blink camera?

Rechargeable NiMH batteries work but are not recommended. They have a lower voltage than alkaline batteries and may cause the camera to show a low battery warning even when fully charged. Alkaline batteries provide more consistent performance and longer runtime.

What should I do if one battery is dead but the other is fine?

Replace both batteries at the same time, even if only one is low. Mixing old and new batteries can cause the camera to drain the new battery faster and may trigger false low battery warnings. Always install two fresh batteries together.

Will the camera lose its settings when I change the batteries?

No. Your camera's settings, recordings, and network connection remain unchanged when you swap batteries. The camera will restart and reconnect to your Wi-Fi automatically, but all your configurations stay in place.

What if the battery compartment is stuck and won't open?

Try warming the camera slightly by holding it in your hands for a minute—plastic can expand slightly with warmth and make the panel easier to slide. Use your fingernail or a plastic spoon handle to gently pry at the seam, but avoid metal tools that could damage the camera. If it's still stuck, contact Blink support rather than forcing it.
