Why This Matters / Understanding the Problem

You know that moment when your Arlo camera suddenly goes offline, and you’re left wondering if it’s a Wi-Fi glitch or a security risk? More often than not, it’s the batteries. I’ve been there—mid-week, kids at school, and my front porch camera blinks out. No alerts, no motion detection. Just silence.

Arlo cameras are fantastic for home security, but their rechargeable or disposable batteries don’t last forever. Whether you use the Arlo Ultra, Pro 3, Pro 4, or older models, learning how to replace Arlo camera batteries in 5 simple steps can save you time, stress, and false alarm calls to your security company.

The good news? It’s not rocket science. But if you’ve never done it before, the process can feel a little intimidating. That’s why I’m walking you through it like I’m sitting next to you, coffee in hand, showing you exactly what to do—no tech jargon, no fluff.

From choosing the right battery type to avoiding common pitfalls (like cracking the camera case), this guide covers everything you need to keep your Arlo cameras running smoothly. And yes, we’ll even talk about how to extend battery life so you’re not doing this every few months.

What You Need

Before we dive in, let’s gather your toolkit. The good news? You don’t need a fancy repair kit or a degree in electronics. Most of this you might already have.

• Replacement batteries – Check your Arlo model first. Arlo Pro and Ultra use proprietary lithium-ion batteries (like the Arlo 100% Rechargeable Battery), while older models may use AA or AAA.
• Small Phillips-head screwdriver – A precision one works best. I keep a tiny set in my kitchen junk drawer for moments like this.
• Plastic pry tool or old credit card – Prevents scratching or cracking the camera housing.
• Clean microfiber cloth – For wiping dust off the lens and contacts.
• Your smartphone with the Arlo app – To test battery levels and reconnect after replacement.
• Optional: Battery charging station – If you use rechargeable batteries, this makes the swap faster.

Pro tip: Keep a spare battery charged and ready. That way, when one dies, you can swap it instantly and charge the old one later. I keep two in rotation—one in the camera, one charging. It’s a game-changer.

And remember: if you’re using how to replace Arlo camera batteries in 5 simple steps as your go-to method, having the right tools makes all the difference between a 10-minute fix and a frustrating hour of fumbling.

Step-by-Step Guide to How to Replace Arlo Camera Batteries in 5 Simple Steps

Step 1: Turn Off and Disconnect the Camera

First things first—safety. Even though Arlo cameras are low-voltage, it’s smart to power them down before opening the battery compartment.

Open the Arlo app on your phone. Tap the camera you’re working on, then select “Settings” > “Device Info” > “Power Off.” This shuts down the camera completely and prevents any accidental triggers while you’re working.

Next, physically remove the camera from its mount. Most Arlo models have a quick-release base. Just twist or slide the camera off. I like to lay it on a soft surface (like a towel) to avoid scratching the lens or casing.

Warning: Don’t force the camera off if it feels stuck. Some mounts have locking mechanisms. Check your model’s manual if unsure. Forcing it can damage the mount or camera.

Once it’s off, inspect the battery compartment. On most Arlo Pro and Ultra models, it’s on the back, secured with one or two small screws. Older models (like the original Arlo) may have a slide-out tray.

Now you’re ready for the next step in how to replace Arlo camera batteries in 5 simple steps—opening the compartment.

Step 2: Open the Battery Compartment

Grab your Phillips-head screwdriver and remove the screw(s) holding the battery door in place. Set the screws aside in a small bowl or magnetic tray—don’t lose them! I once dropped one into a vent and spent 20 minutes fishing it out with a magnet.

Once the screws are out, use your plastic pry tool or credit card to gently separate the battery door from the camera body. Start at one corner and work your way around. Apply even pressure—don’t pry too hard.

On some models, like the Arlo Pro 4, the door is held by small plastic tabs. A little wiggle helps, but go slow. I’ve seen people crack the housing by yanking it open.

Once the door is off, you’ll see the battery. It’s usually a black or gray rectangle with a small ribbon cable attached. Don’t pull the cable yet!

Tip: Take a quick photo with your phone before removing anything. This helps you remember how the battery was positioned—especially the cable orientation.

This step is crucial in how to replace Arlo camera batteries in 5 simple steps because rushing here can lead to damaged connectors or a camera that won’t power on later.

Step 3: Disconnect and Remove the Old Battery

Now comes the delicate part: disconnecting the battery cable. The ribbon cable plugs into a small connector on the camera’s circuit board. It’s not a USB port—it’s a tiny latch system.

Use your fingernail or the pry tool to gently lift the black locking tab on the connector. It usually flips up about 30 degrees. Don’t force it. Once it’s up, the cable should slide out easily.

Now, carefully remove the old battery. If it’s stuck, there might be a small piece of double-sided tape holding it in. Slide the pry tool under one edge to loosen it. Don’t use metal tools here—you could scratch the board or short a circuit.

Once the battery is free, inspect the contacts. If they’re dirty or corroded, wipe them with a microfiber cloth. Clean contacts mean better connection and longer life for your new battery.

Common mistake: Forgetting to lift the locking tab and trying to yank the cable. This is the #1 cause of damaged Arlo cameras during battery swaps. Be patient. It’s a tiny latch, not a plug.

You’re halfway through how to replace Arlo camera batteries in 5 simple steps—and the hardest part is behind you.

Step 4: Install the New Battery

Now for the fun part: installing the new battery. First, make sure it’s fully charged. I always check the charge level in the Arlo app before swapping. A partially charged battery might not last a full day.

Align the new battery the same way the old one was positioned. Match the shape and orientation. Then, gently slide the ribbon cable into the connector until it stops.

Now, lower the black locking tab back into place. It should snap down smoothly. If it’s stiff, double-check the cable is fully inserted. Never force the tab.

Once the cable is secure, press the battery gently into the compartment. If your model uses tape, you don’t need to reapply it—most new batteries come with adhesive. But if it’s loose, a small piece of double-sided tape can help.

Finally, reattach the battery door and screw it back in. Don’t overtighten the screw—just snug is fine. Overtightening can strip the plastic or crack the housing.

Pro tip: Before closing, give the cable a tiny tug to make sure it’s locked in. If it moves, the tab isn’t down properly.

This step is where precision matters. A loose cable or misaligned battery can cause connection issues. But once it’s in, you’re almost done with how to replace Arlo camera batteries in 5 simple steps.

Step 5: Reconnect and Test the Camera

Now, reattach the camera to its mount. Make sure it’s secure and aimed correctly. I like to do a quick visual check—is it pointing at the front door? The driveway? Adjust if needed.

Open the Arlo app and power the camera back on. Go to “Settings” > “Device Info” > “Power On.” You should see the camera come online within 30 seconds.

Check the battery level in the app. It should show 100% (or close to it). If it’s low, the battery might not be fully charged or the connection is poor.

Test the camera by triggering motion—walk in front of it. Check the live feed and verify that recordings are saved to the cloud or SD card.

Also, listen for the startup chime. Most Arlo cameras make a soft “beep” when they boot up. No sound? That could mean a power issue.

Warning: If the camera doesn’t power on, don’t panic. Double-check the cable connection, ensure the battery is charged, and verify the screws are tight. If it still fails, try the old battery to see if the issue is with the camera, not the battery.

Once everything’s working, you’ve successfully completed how to replace Arlo camera batteries in 5 simple steps—congrats!

Pro Tips & Common Mistakes to Avoid

After replacing batteries on a dozen Arlo cameras (and making every mistake in the book), here are my hard-earned insights.

Use Genuine or High-Quality Third-Party Batteries

Not all batteries are created equal. I once bought a cheap third-party battery off Amazon—it died in two weeks. Stick with Arlo-branded batteries or reputable brands like Anker or Energizer (if compatible).

Cheap batteries often have lower capacity, poor connectors, or safety issues. Your camera’s performance depends on consistent power.

Label Your Batteries

I label my spare batteries with the date I bought them and the last charge cycle. This helps me rotate them fairly and avoid using a battery that’s past its prime. Lithium-ion batteries degrade over time—even if not used.

Clean the Camera While You’re At It

While the battery is out, take a moment to wipe the lens and sensor with a microfiber cloth. Dust and grime can reduce image quality and trigger false motion alerts.

I also check the weatherproof seal. If it’s cracked or loose, replace it. Water damage is a real risk with outdoor cameras.

Avoid Overcharging

Don’t leave batteries on the charger for days. Most Arlo batteries take 3–4 hours to charge. Overcharging reduces lifespan. I use a timer or smart plug to cut power after 5 hours.

Common Mistakes to Avoid

• Forgetting to power off the camera – Can cause data loss or app glitches.
• Using metal tools near the circuit board – Risk of shorting or scratching.
• Skipping the test phase – Always verify the camera works before walking away.
• Ignoring firmware updates – Outdated firmware can cause battery drain. Update via the Arlo app.
• Not having a backup battery – A charged spare means zero downtime.

These tips are key to mastering how to replace Arlo camera batteries in 5 simple steps and keeping your security system running smoothly.

FAQs About How to Replace Arlo Camera Batteries in 5 Simple Steps

Can I use AA batteries in my Arlo camera?

Only older Arlo models (like the original Arlo) support AA batteries. Most newer models—Pro 3, Pro 4, Ultra—use proprietary lithium-ion batteries. Check your model’s manual or the Arlo website to confirm. Using AA in a lithium-ion model will damage the camera.

How long do Arlo batteries last?

It depends. In moderate climates with 10–20 motion events per day, a fully charged battery lasts 3–6 months. In extreme cold or with heavy usage, it may drop to 1–2 months. I’ve found that cameras facing a busy street drain faster than those in quiet backyards.

Can I replace the battery without removing the camera?

Technically, yes—but not recommended. Some Arlo mounts have removable battery doors, but the camera needs to be stable and accessible. I’ve tried it once and dropped the camera. Not fun. Always remove it for safety and better access.

Why won’t my camera power on after battery replacement?

Most likely, the ribbon cable isn’t properly seated. Double-check that the locking tab is down and the cable is fully inserted. Also, verify the battery is charged. If both are fine, try resetting the camera via the app (Settings > Device Info > Reset).

Are third-party batteries safe?

Some are—but many aren’t. I recommend only batteries with good reviews, UL certification, and a warranty. Avoid no-name brands. A bad battery can overheat or damage your camera. When in doubt, go with Arlo’s official battery.

How do I know when it’s time to replace the battery?

The Arlo app shows battery percentage. When it drops below 20%, you’ll get a notification. But I replace mine around 30% to avoid sudden shutdowns. Also, if the camera starts missing recordings or going offline frequently, the battery might be dying.

Can I charge the battery while it’s in the camera?

Yes! Arlo Pro and Ultra models have a USB-C port on the side. Just plug in a cable and charge it in place. This is handy if you don’t want to remove the camera. But I still recommend removing it occasionally for cleaning and inspection.

Final Thoughts

Learning how to replace Arlo camera batteries in 5 simple steps isn’t just about swapping a part—it’s about taking control of your home security. No more waiting for a technician, no more false alarms from a dead camera.

This process takes less than 15 minutes once you’ve done it once. And with the right tools and a little care, it’s something anyone can do. Whether you’re a tech newbie or a seasoned DIYer, this skill pays off in peace of mind.

My advice? Keep a spare battery charged, label your batteries, and clean your camera while you’re at it. And if you’re using rechargeable batteries, consider getting a second charging station so you’re never without power.

Remember, a well-maintained Arlo camera is a reliable one. And reliability is what security is all about. So next time that battery dies, don’t panic. Just follow these five simple steps—and you’ll be back online in no time.
