Why This Matters / Understanding the Problem

Let’s be honest—nothing’s more frustrating than checking your Arlo Pro 4 camera, only to see that dreaded low battery alert. You rely on it for home security, maybe even to keep an eye on your pets while you’re out. When the battery dies, your peace of mind dies with it.

Over time, the rechargeable battery inside your Arlo Pro 4 wears down—just like your phone’s. The good news? You don’t need to call a technician. With a little patience and the right steps, learning how to change battery in Arlo Pro 4 camera 2026 guide is easier than you think. I’ve been there: standing in my backyard, fumbling with the camera, wondering if I’d break something. Spoiler: I didn’t. And you won’t either.

This guide walks you through the entire process—safely, cleanly, and without voiding your warranty. Whether you’re a first-timer or just need a refresher, this how to change battery in Arlo Pro 4 camera 2026 guide is your go-to resource.

What You Need

Before we dive in, let’s gather your toolkit. Don’t worry—this isn’t rocket science. You’ll only need a few items, most of which you might already have at home.

• Replacement battery: Arlo Pro 4 uses a specific lithium-ion battery (model: 3.7V 3.6Ah). Make sure it’s compatible. I recommend getting the official Arlo battery—yes, it costs more, but it lasts longer and avoids overheating risks.
• Small Phillips-head screwdriver: The camera uses tiny screws. A precision screwdriver set works best. I use the one from my old eyeglass repair kit—it’s perfect.
• Plastic pry tool or guitar pick: You’ll need this to open the camera housing without scratching it. A butter knife works in a pinch, but plastic is safer.
• Clean microfiber cloth: Wipe off dust and fingerprints before reassembling.
• Arlo app (on your phone): You’ll need this to sync the camera after the swap.
• Optional but helpful: Magnetic tray for screws (I use an old pill case—keeps everything from rolling away).

Pro insight: Buy the battery from Arlo’s website or Amazon (sold by Amazon, not a third-party seller). Cheap knockoffs may not fit or could damage your camera. I learned that the hard way when a third-party battery swelled after three months.

Step-by-Step Guide to How to Change Battery in Arlo Pro 4 Camera 2026 Guide

Alright, let’s get into the nitty-gritty. Follow these steps carefully, and you’ll have your Arlo Pro 4 back online in under 20 minutes. I’ve done this five times now—three for my own cameras, two for neighbors who were too nervous to try.

Step 1: Power Down the Camera

First, don’t just yank the camera off the wall. That’s a recipe for a cracked mount or a loose screw. Instead, open the Arlo app on your phone.

• Tap the camera you’re working on.
• Go to Settings > Camera Settings > Power.
• Select “Power Off”.

This shuts down the camera completely. Why does this matter? It prevents data corruption and gives you a clean start. Think of it like turning off your computer before unplugging it.

Warning: Never remove the battery while the camera is on. The Arlo Pro 4 doesn’t have a backup power source, so pulling the battery mid-operation could brick the device.

Step 2: Remove the Camera from Its Mount

Now, gently twist the camera counterclockwise until it clicks loose. The Arlo Pro 4 uses a magnetic mount, so it should come off with a firm twist—no tools needed.

• Hold the camera with one hand.
• Rotate the base with the other until it releases.

Place the camera on a soft surface—like a towel or your kitchen counter. I once dropped mine on tile and cracked the lens cover. Not fun.

Pro tip: Take a photo of the camera’s position before removing it. That way, you can easily reattach it at the same angle later.

Step 3: Open the Camera Housing

This is where it gets a little delicate. The Arlo Pro 4 has a sealed front and back. You need to remove the front cover to access the battery.

• Look for the small seam between the front and back halves.
• Insert your plastic pry tool or guitar pick into the seam near the Arlo logo.
• Gently wiggle it around the edge to release the clips.

Go slow. There are 12 tiny plastic clips holding the housing together. If you force it, you’ll break one. I’ve seen it happen—once, a friend snapped a clip and had to tape the camera shut. Not ideal.

Pro insight: Start at the top near the lens. The clips there are slightly easier to release. Work your way down each side. Avoid the bottom—there’s a rubber grommet for the charging port that can tear if you’re not careful.

Step 4: Remove the Old Battery

Once the front cover is off, you’ll see the internal components. The battery is the large black rectangle in the center, connected by a small white connector.

• Locate the battery connector (white plastic tab with wires).
• Use your fingernail or a plastic tool to gently lift the tab upward.
• Pull the connector straight out. Don’t yank the wires.

The battery is held in place with a small amount of adhesive. You’ll need to wiggle it free.

• Slide your plastic tool under one edge.
• Lift gently until the battery pops out.

Don’t worry if it takes a few tries. The adhesive is light, but it’s there to prevent rattling during wind or vibration.

Warning: Never use metal tools to pry the battery. Lithium-ion batteries can short-circuit if punctured, causing smoke or fire. I keep a pair of plastic spudgers just for this.

Step 5: Install the New Battery

Now for the fun part—putting in the fresh battery. Make sure it’s the right model (check the label: 3.7V 3.6Ah).

• Align the battery with the slot. The connector should face the same direction as the old one.
• Press it into place. It should sit flush with the housing.
• Reconnect the white connector by sliding it straight in until it clicks.

Double-check that the connector is fully seated. A loose connection can cause the camera to power off unexpectedly.

Pro insight: If the battery feels loose, use a small piece of double-sided tape to secure it. Arlo doesn’t include adhesive with the replacement, but a tiny strip (like from a Post-it note) works fine.

Step 6: Reassemble the Camera

Time to put it all back together. This is where many people rush and end up with a misaligned lens or a gap in the housing.

• Align the front cover with the back half. The Arlo logo should face forward.
• Press the two halves together, starting at the top.
• Work your way around, applying even pressure until all clips snap in.

You’ll hear little clicks—that’s good. If you don’t hear them, the clips aren’t fully engaged. Gently press again.

Wipe the lens and housing with your microfiber cloth. Smudges on the lens can blur your video feed.

Step 7: Reattach to Mount & Power On

Now, place the camera back on the magnetic mount.

• Align the base with the mount.
• Twist clockwise until it locks.

Open the Arlo app. The camera should appear as “Offline” at first. Wait 30–60 seconds. It will reconnect automatically.

• Tap the camera.
• Check the battery level in Settings > Battery.

You should see a full or near-full charge. If it’s low, the battery may need a few charging cycles to reach peak performance.

Pro insight: After the first charge, run a test recording. Check the app for motion alerts and video quality. This ensures the camera is working properly post-swap.

Step 8: Sync & Calibrate (If Needed)

Rarely, the camera might need to re-sync with your base station or Wi-Fi. If it doesn’t connect:

• Go to Settings > Camera Settings > Sync.
• Follow the on-screen prompts to re-pair.

You may also need to recalibrate motion detection zones. I had to do this once after a battery change—the camera was triggering false alerts from a tree branch. Took five minutes to fix in the app.

Pro Tips & Common Mistakes to Avoid

After five battery swaps, I’ve learned a few things the hard way. Here’s what to watch out for:

• Don’t rush the housing removal: Those plastic clips are fragile. Take your time. I once broke one and had to use a tiny zip tie to hold the cover on. Not pretty.
• Label your screws: There are only two, but they’re tiny. If you lose one, you’ll need to buy a replacement kit. I use a magnetic tray to keep them safe.
• Check the battery connector: If the camera won’t power on, the connector might be loose. Open it again and reseat it. I’ve had to do this twice.
• Avoid over-tightening screws: The housing is plastic. One overzealous turn and the threads strip. Hand-tighten only.
• Test in low light: The Arlo Pro 4’s night vision uses IR LEDs. After reassembly, check the night mode video. If it’s blurry, the lens might be misaligned.

Warning: Never use a hair dryer or heat gun to soften the adhesive. Heat can damage the battery or internal circuits. Patience is your best tool.

And a personal favorite: Take photos at each step. I snap a quick pic when I remove the old battery, when I install the new one, and after reassembly. If something goes wrong, I have a visual reference to troubleshoot.

FAQs About How to Change Battery in Arlo Pro 4 Camera 2026 Guide

Let’s tackle the questions I get most often from friends and neighbors.

Can I use a third-party battery?

Technically, yes—but I don’t recommend it. Third-party batteries may not have the same safety certifications. One of my neighbors used a cheap battery, and it swelled after six weeks. It pushed the housing apart and ruined the camera. Stick with Arlo’s official battery for peace of mind.

How long does the battery last?

With normal use (motion detection, 10–15 recordings per day), expect 3–6 months. Heavy use (like a busy street view) might drain it in 2 months. The battery life varies based on temperature, Wi-Fi signal, and how often it records.

Do I need to charge the new battery first?

No. Arlo batteries ship with a partial charge (around 40%). You can install it right away. But for best performance, charge it fully before first use. I plug mine in for 2–3 hours after installation.

What if my camera won’t turn on after the swap?

First, check the battery connector. Make sure it’s fully seated. If it’s loose, the camera won’t power on. If that doesn’t work, try a factory reset in the app: Settings > Camera Settings > Remove Camera > Re-add. This forces a fresh connection.

Is the process the same for the Arlo Pro 3?

No. The Pro 3 has a removable battery pack, so you just pop it out. The Pro 4 is more integrated, which is why this how to change battery in Arlo Pro 4 camera 2026 guide focuses on internal replacement. Don’t assume they’re the same!

Can I replace the battery while the camera is on the mount?

It’s possible, but not safe. The magnetic mount isn’t designed to hold the camera during disassembly. You risk dropping it or damaging the housing. Always remove it first.

How do I dispose of the old battery?

Lithium-ion batteries shouldn’t go in the trash. Take it to a local electronics recycling center or a big-box store (like Best Buy or Home Depot). They have drop-off bins. I keep my old batteries in a metal container until I can recycle them.

Final Thoughts

Changing the battery in your Arlo Pro 4 isn’t scary—it’s empowering. You’re taking control of your home security, saving money on replacements, and learning a useful skill. This how to change battery in Arlo Pro 4 camera 2026 guide gives you everything you need to do it right.

Remember: go slow, keep your tools organized, and test the camera afterward. If you hit a snag, don’t panic. Most issues (like a loose connector) are fixable with a second look.

And here’s my final tip: Schedule your battery swaps. Set a reminder every 4 months to check the level. That way, you’ll never get caught off guard by a dead camera.

You’ve got this. Now go swap that battery and enjoy your fully charged, fully functional Arlo Pro 4.
