To replace Blink Outdoor 4 batteries, install 2 new 1.5V lithium AA batteries with their positive and negative ends matched to the compartment marks. Use non-rechargeable lithium cells, replace both together, and close the rear cover fully before checking the camera.

The correct battery chemistry matters as much as the AA size. Alkaline and rechargeable AA batteries are not the specified replacement for this camera.

Blink Outdoor 4 uses 2 non-rechargeable lithium AA batteries. Keep a matched pair on hand so both cells are replaced at the same time.

Don't confuse this model with cameras that use CR123 cells or a built-in rechargeable battery. For general battery-powered camera basics, see what a battery powered security camera is.

Replace the batteries with the camera removed from its mount and the compartment dry. Use the opening tool supplied with the camera and avoid forcing the cover.

  1. Remove the camera from its mount.
  2. Open the rear cover using the supplied opening tool and the camera's instructions.
  3. Take out both old batteries.
  4. Insert 2 new lithium AA batteries, following the polarity marks.
  5. Close the rear cover securely and remount the camera.
  6. Check the camera's status in the Blink app.

Keep the batteries away from children and dispose of used cells according to local battery recycling guidance. Don't mix old and new cells, different brands, or different chemistries in the same camera.

Choose lithium AA batteries, not CR123 batteries. The Energizer Ultimate Lithium AA pack contains 8 AA cells and is identified as compatible with Blink Camera; its cells are 1.5V lithium and single use.

Energizer says these AA batteries are designed to work across a range of temperatures and can remain in storage for up to 25 years. Those are manufacturer claims, not a guarantee of runtime in a particular camera.

Avoid buying based on the word “lithium” alone. Energizer 123 Lithium Batteries are 3V CR123A cells, a different size and voltage from the AA batteries Outdoor 4 uses.

Compare camera battery sizes and chemistries in our guide to best batteries for security cameras. If you're also replacing cells in an Arlo camera, follow its model-specific steps in our Arlo security camera battery replacement guide.

What should you check if the camera won't turn on?

Check battery type, polarity, and cover fit first. A correctly sized battery installed backward or a cover that hasn't latched can prevent normal operation.

Remove the cells and confirm both are lithium AA batteries. Reinsert them according to the polarity marks, then press the cover closed without forcing it.

If the camera still doesn't respond, check the Blink app and follow the manufacturer's troubleshooting steps for Outdoor 4. Keep the battery compartment dry and inspect the cells for damage or leakage before installing them.

Use the specified non-rechargeable lithium AA cells unless Blink's instructions for your exact model say otherwise. Rechargeable batteries can use a different chemistry and voltage, so matching the AA shape alone doesn't confirm compatibility.

Battery replacement is also different from hardwiring. See whether Blink Outdoor 4 can be hardwired before planning a fixed power setup.

A battery camera may suit a spot where a power cable is difficult to run. If you prefer a camera connected to an outlet, learn what a plug in security camera does.

How can you reduce interruptions after a battery change?

Place the camera where its wireless connection is stable and where you can reach it safely for maintenance. If you're comparing wire-free outdoor models, see the best 4K wireless outdoor cameras.

Mounting and access both affect how easy battery replacement will be.

Before installing the camera, review how to mount Blink security cameras and choose a reachable position. If you are comparing battery-powered indoor options, see our guide to the best indoor battery operated security cameras.

VISION WELL describes this camera as rechargeable and wire-free, with app access and Wi-Fi connectivity. It is a separate camera system, so check its own instructions and requirements before choosing it as an alternative.

Which batteries should you keep on hand?

For Blink Outdoor 4, keep a pair of non-rechargeable lithium AA batteries ready. The Energizer Ultimate Lithium AA pack contains 8 cells, while the 3V Energizer 123 pack is intended for devices that take CR123A batteries.

Replace the cells together and follow the compartment marks every time. If the camera still loses power with fresh, correctly installed batteries, check the cover, app status, and Blink's model-specific support guidance.
