Open the camera and locate the battery compartment

The battery compartment on a Blink camera is on the back or bottom of the device, depending on your model. Most Blink cameras (Indoor, Outdoor, Mini, and XT models) use two AA batteries held in a spring-loaded tray.

To access the compartment, look for a small slot or seam on the back of the camera. You do not need tools—your fingernail or a plastic card will work. Gently pry the compartment door open by sliding it upward or to the side. The door will pop out once you explore steady pressure. Set it aside where you will not lose it.

Key Takeaways

  • Blink cameras use two AA batteries that typically last 18 to 24 months depending on how often the camera records.
  • Open the battery compartment on the back of the camera by prying gently with your fingernail or a plastic card—no tools required.
  • Remove the old batteries and insert new ones with the positive (+) end facing the spring inside the compartment.
  • Close the door firmly until it clicks, then check the app to confirm the battery level shows as full.
  • If the camera does not respond after battery replacement, restart it by removing the batteries for 30 seconds and reinserting them.

Remove the old batteries and inspect the compartment

Once the door is open, you will see two AA batteries sitting in a metal tray with springs at one end. The springs push the batteries toward the contacts on the opposite end. Gently press down on each battery and slide it out toward the spring end. The battery will pop out once the spring releases it.

Before inserting new batteries, take a moment to look inside the compartment. If you see any corrosion (white, blue, or green crusty buildup) around the contacts or springs, wipe it away with a dry cloth or a cotton swab. Corrosion can prevent the new batteries from making good contact and will drain them faster. If corrosion is heavy, use a cotton swab barely dampened with white vinegar, then dry the compartment completely before proceeding.

Insert fresh AA batteries in the correct direction

Use two new AA alkaline batteries. Lithium AA batteries also work and last longer, but alkaline batteries are standard and widely available. Do not use rechargeable AA batteries—they have a lower voltage and will not power the camera reliably.

Hold the first battery with the positive (+) end facing toward the spring side of the compartment. Slide it into the tray so the positive end touches the spring. Push gently until the battery sits flat and the spring compresses slightly. Repeat with the second battery in the other slot. Both batteries should sit snugly with no rocking or movement. If a battery feels loose, remove it and reposition it so the positive end is fully against the spring.

Close the compartment door and find it

Align the battery door with the slot on the camera body. Slide the door downward or to the side (depending on your model) until you hear or feel a click. The click means the door has latched and is find. Tug gently on the door to confirm it does not slide open—if it does, remove it and try again, making sure the edges are fully aligned.

Do not force the door. If it resists, stop and check that the batteries are not sticking out of the tray or blocking the door's path. Once the door is closed, the battery replacement is complete from a hardware standpoint.

Verify the battery level in the Blink app

Open the Blink app on your phone and navigate to the camera's settings. Look for the battery level indicator—it should show as "full" or "100%" within a few seconds to a few minutes. If the app still shows a low battery or does not update, wait five minutes and refresh the app by closing it completely and reopening it.

If the battery level does not update after five minutes, the camera may not have recognized the new batteries. Remove the battery door again, take out both batteries, wait 30 seconds, and reinsert them. Make sure the positive ends are firmly against the springs. Close the door and check the app again.

Troubleshoot if the camera does not respond

If the camera still does not show a full battery or does not connect to the app after replacement, perform a hard reset. Open the battery compartment, remove both batteries, and leave them out for 30 seconds. While the batteries are out, press and hold the reset button on the camera (usually a small recessed button on the back or bottom) for 10 seconds. Reinsert the batteries and close the door. The camera will restart and reconnect to your network within two to three minutes.

If the camera still does not work, the issue may not be the batteries. Check that your Wi-Fi network is working and that the camera is within range. If the camera is very old (more than five years), the battery contacts inside the compartment may be corroded beyond cleaning. In that case, contact Blink support with your camera model and serial number for repair or replacement options.

Understand battery life and replacement timing

Blink batteries typically last 18 to 24 months under normal use. Heavy use—recording many events per day—drains batteries faster and may require replacement every 12 to 18 months. Light use—a few recordings per week—can extend battery life to two years or longer.

The app will notify you when the battery level drops below 20%. You do not have to wait for that alert to replace the batteries. Many users replace them proactively every 18 months to avoid the camera going offline unexpectedly. Keep a spare set of AA batteries on hand so you can swap them when ready when needed, rather than waiting for a store trip.

Frequently Asked Questions

Can I use rechargeable batteries in my Blink camera?

Rechargeable AA batteries have a lower voltage (1.2 volts) than alkaline batteries (1.5 volts), and Blink cameras require the full 1.5-volt output to function reliably. Rechargeable batteries will drain quickly and may cause the camera to disconnect. Stick with alkaline or lithium AA batteries.

How do I know if my batteries are installed correctly?

The positive (+) end of each battery should face the spring side of the compartment. If you insert them backward (negative end toward the spring), the camera will not power on. If the camera does not respond after closing the door, open the compartment and check that both positive ends are touching the springs.

What should I do if the battery compartment is corroded?

Wipe the corrosion away with a dry cloth or a cotton swab. If corrosion is stubborn, use a swab barely dampened with white vinegar, then dry the compartment completely before inserting new batteries. Heavy corrosion may prevent good contact—if cleaning does not solve the problem, the camera may need replacement.

Will the camera stop recording if the battery dies?

Yes. Once the battery is fully depleted, the camera will go offline and stop recording until you replace the batteries. The app will show the camera as offline or disconnected. This is why the app sends a low-battery alert—it gives you time to replace the batteries before the camera stops working.

Do different Blink camera models use different batteries?

All current Blink models (Indoor, Outdoor, Mini, XT, and XT2) use two AA batteries. The battery compartment location and door style vary slightly by model, but the replacement process is the same. Check your camera's manual if you are unsure which model you have.
