How to Replace Arlo Security Camera Batteries
For Arlo security camera battery replacement, first identify the exact camera model and match its battery type. Some Arlo cameras use a removable rechargeable pack, some use replaceable cells, and others have built-in batteries that aren't meant to be changed by the owner.
Don't choose a battery by appearance alone. Check the model label in the Arlo app or on the camera, then confirm the replacement type in that model's manual.
If you’re new to battery-powered cameras, what a battery powered security camera is explains how battery power differs from a plug-in setup.
Which Arlo cameras have replaceable batteries?
Battery access and battery type depend on the Arlo model. A removable battery door or pack suggests that the battery may be replaceable, but the manual is the final check for both the correct part and the replacement steps.
Before ordering, write down the model name and look up its battery instructions. Check whether the camera takes a specific rechargeable pack, standard cells, or a built-in battery.
A battery from another Arlo model may have a different shape, connector, or electrical requirements.
If the manual names a rechargeable pack, use a compatible pack made for that model. If it specifies individual cells, match the type and count exactly.
Don't mix old and new cells or different battery types.
How do you replace an Arlo camera battery?
Power down or remove the camera from its mount if the model's manual calls for it, then open the battery compartment and install the compatible battery in the marked direction. Close the door securely and check that the camera reconnects.
- Confirm the exact model and compatible battery type.
- Bring the camera within reach and support it while opening the compartment.
- Remove the old pack or cells as directed by the manual.
- Insert the replacement with its contacts and polarity aligned as marked.
- Close the compartment fully and remount the camera if you removed it.
- Check the app for the camera's connection and battery status.
Don't force a pack into the compartment or press on a connector that doesn't line up. If the door won't close, remove the battery and confirm that you have the correct one.
When another brand's camera uses removable cells, its process may differ. Our guide to Blink Outdoor 4 battery replacement covers that camera's battery change.
What should you check before ordering a replacement?
Match the replacement to your Arlo model's battery type, shape, and instructions. The phrase “Arlo battery” can refer to different parts, so the camera model matters more than a broad search term.
A CR123 cell is a 3-volt lithium battery. The Energizer 123 Lithium Batteries are single-use CR123A cells, so consider them only if your camera manual specifies that battery type and count.
These aren't a substitute for a rechargeable Arlo battery pack. Check the battery label and manual before buying, even if a cell looks like the one currently installed.
The Energizer Ultimate Lithium AA Batteries are lithium AA cells. Use them only if the instructions for your exact camera call for AA batteries; don't use them in place of a rechargeable pack or CR123A cells.
For more help comparing battery types, see best batteries for security cameras. That guide can help you understand the options, but your Arlo model's instructions determine compatibility.
What if the battery is built in or the correct pack is hard to find?
If your Arlo camera has a built-in battery or its pack isn't user-replaceable, don't pry open the housing. If you are considering another camera instead, compare solar security cameras with lights for an outdoor setup.
Check the model's support information for service options or consider a different camera if replacement is impractical.
One alternative is to choose a camera with a rechargeable battery that you can access as part of its intended design. The VISION WELL Security Cameras Wireless Outdoor is a separate camera with a rechargeable battery, not a replacement pack for an Arlo device.
If you need a camera for indoor use, compare battery operated indoor security cameras. If your camera can stay near an outlet, what a plug in security camera does may help you decide whether a wired power source fits better.
Why might an Arlo camera stay offline after a battery change?
A camera may need time to reconnect after you replace its battery. Confirm the pack is seated, the compartment is closed, and the battery has charge before changing network settings.
If the camera remains offline, check its status in the app and follow the manual's steps for your model. Confirm the battery contacts are clean and the battery is the correct type.
Avoid forcing or bending contacts.
Battery changes don't solve every connection issue. If the camera still won't connect, our guide to whether security cameras can work without WiFi explains how WiFi fits into a camera setup.
For a wireless doorbell, see Arlo video doorbells: wired vs wireless; cellular support also varies, as covered in which Arlo cameras support cellular connections.
How do you choose the right replacement?
For an Arlo security camera battery replacement, let the model manual decide the battery type. Choose a rechargeable pack if the camera calls for one, and use individual cells only when the instructions specify their type and count.
Use CR123A cells only for a camera that explicitly requires them. Use AA cells only for a model that specifies AA.
If the battery is built in, check service options instead of opening the camera. These checks help you avoid buying a battery that won't fit or work.
Frequently asked questions
Which Arlo cameras have replaceable batteries?
Arlo battery designs vary by model. Some cameras use a removable rechargeable pack, some older wire-free models use replaceable cells, and some newer cameras have a built-in battery.
Check the exact model name and its manual before ordering, since batteries that look similar may not fit or work.
Can I use regular AA batteries in an Arlo camera?
Only use AA batteries if the manual for your exact Arlo model calls for them. A battery that fits the compartment can still have the wrong chemistry or voltage.
Don't substitute AA cells for a rechargeable Arlo pack or another specified battery type.
Can I replace an Arlo camera battery without removing the camera?
Often, you can reach a removable battery through the camera's battery door without taking the mount down. The setup depends on the model and how it is mounted.
Support the camera as you open the compartment, and follow its manual if it must be detached first.
Does changing an Arlo battery erase camera settings?
A battery change usually doesn't require you to set up the camera again, but behavior can vary by model. Close the battery door securely, let the camera reconnect, and check its status in the app.
If it stays offline, follow the model's troubleshooting steps.
