Blink cameras run on AA or AAA batteries depending on the model, and you swap them out by opening the battery compartment on the back of the camera

The exact steps depend on whether you own a Blink Indoor, Blink Outdoor, Blink Mini, or Blink Video Doorbell — each one holds batteries differently. Most Blink cameras use two AA batteries, but the Blink Mini plugs into power and has no battery to replace. Before you start, check which Blink model you own by looking at the device itself or your purchase receipt.

Battery life varies by model and usage. Blink Indoor and Outdoor cameras typically run for two years on a set of AA batteries if motion detection happens a few times per day. If your camera records constantly or detects motion dozens of times daily, batteries drain faster — sometimes in six months or less. The Blink app will send you a notification when the battery is low, usually when it drops below 110 mV.

Key Takeaways

  • Blink Indoor and Outdoor cameras use two AA batteries; the Blink Mini has no battery because it plugs into power.
  • Open the battery compartment on the back of the camera by sliding or unclipping the cover, depending on your model.
  • Replace old batteries with fresh AA batteries, making sure the positive and negative ends face the correct direction.
  • The Blink app will notify you when the battery is low, and you do not need to remove the camera from its mount to change batteries.

How to open the battery compartment on Blink Indoor and Outdoor cameras

Locate the battery compartment on the back of your camera. On Blink Indoor and Blink Outdoor models, it is a rectangular panel on the rear face. Look for a small slot or indentation along one edge — this is where you insert a coin or flathead screwdriver to pry the compartment open.

Insert a coin (a dime or penny works) into the slot and turn it counterclockwise, or use a small flathead screwdriver. The compartment should pop open or slide out slightly. Do not force it — if it does not budge after gentle pressure, check that you are turning in the correct direction. Once the compartment is loose, pull it away from the camera body to fully expose the battery slots inside.

Removing old batteries and installing new ones

Inside the compartment, you will see two battery slots arranged vertically or side by side. Each slot has a metal contact at the top and bottom. Note which direction the old batteries are facing — the positive end (marked with a + symbol) should point toward the metal contact at the top of each slot.

Gently pull out the old batteries. If they are stuck, wiggle them slightly side to side while pulling. Once both are out, insert two fresh AA batteries into the same slots, making sure the positive end of each battery points upward (toward the top of the camera). The batteries should sit flat in their slots without forcing. Close the compartment by sliding it back into place or pressing it until you hear a click.

What to do if your camera is mounted on a wall or ceiling

You do not need to remove the camera from its mount to change the batteries. The battery compartment is accessible from the back, and you can reach it while the camera stays in place. If the mount makes it difficult to grip the battery compartment cover, you can carefully tilt the camera slightly to improve your angle, but full removal is not necessary.

If your camera is mounted very high or in an awkward spot, consider using a step stool or small ladder to reach it safely. Take your time opening the compartment — rushing increases the risk of dropping the camera or the batteries.

Troubleshooting when the camera does not turn on after a battery change

If your camera does not respond after you install new batteries, first check that both batteries are inserted in the correct direction. The positive end must face upward. Remove the batteries, wait 10 seconds, and reinsert them to ensure they make good contact with the metal terminals inside the compartment.

If the camera still does not respond, try a different set of fresh batteries — the ones you installed may be defective. Some users report that alkaline batteries work more reliably than rechargeable batteries in Blink cameras, though rechargeable AA batteries are compatible. If you have tried two sets of fresh batteries and the camera remains unresponsive, the device itself may have a hardware issue, and you may need to contact Blink support or consult your warranty.

How often to check battery levels in the Blink app

Open the Blink app on your phone and tap on the camera you want to check. Look for a battery icon or battery percentage displayed on the camera's live view screen or in the camera settings. The app shows the voltage in millivolts (mV) — a reading above 110 mV means the battery is in good condition, while anything below 110 mV indicates low battery.

Check your battery levels once a month if your camera records frequently, or every few months if motion detection is rare. This habit prevents the camera from going offline unexpectedly. The Blink app will also send you a push notification when the battery drops below the low threshold, so you do not have to check manually if you have notifications enabled.

Blink Mini and Blink Video Doorbell battery differences

The Blink Mini does not have a battery compartment because it is designed to plug into a USB power adapter or USB port. It draws power continuously from the outlet and does not need battery replacement. If your Blink Mini loses power, check that the USB cable is firmly connected to both the camera and the power adapter, and that the adapter is plugged into a working outlet.

The Blink Video Doorbell uses a rechargeable battery that charges through your home's existing doorbell wiring. You do not replace this battery yourself — instead, the camera charges automatically when wired to your doorbell circuit. If the doorbell battery drains quickly, check that the wiring is connected properly and that your home's doorbell transformer is functioning.

Frequently Asked Questions

Can I use rechargeable AA batteries in my Blink camera?

Yes, rechargeable AA batteries are compatible with Blink Indoor and Outdoor cameras. However, some users report that alkaline batteries last longer and perform more reliably. Rechargeable batteries have a lower voltage output, which may cause the app to show a low battery warning sooner than with alkaline batteries, even though the camera still functions normally.

How long do Blink camera batteries actually last?

Battery life depends on how often your camera detects motion and records video. With light use (a few motion events per day), batteries typically last one to two years. Heavy use (constant recording or dozens of motion events daily) can drain batteries in three to six months. The Blink app notifies you when voltage drops below 110 mV.

Do I need to reset my camera after changing the batteries?

No, you do not need to reset the camera after a battery change. Simply close the battery compartment and the camera will reconnect to your network within a few minutes. If the camera does not reconnect, restart it by removing the batteries for 10 seconds, then reinserting them.

What happens if I insert the batteries backward?

If you insert the batteries with the negative end facing upward, the camera will not power on. The battery contacts inside the compartment are designed to work only when the positive end points toward the top of the camera. Remove the batteries, flip them around, and reinsert them in the correct direction.

Can I leave my Blink camera without batteries while I order new ones?

Yes, you can remove the batteries temporarily without damaging the camera. The camera will go offline and stop recording until you reinstall batteries or plug it in (if it is a Blink Mini). Your recorded video clips remain stored in the Blink cloud, and the camera will reconnect automatically once power is restored.
