How to Change Arlo Camera Batteries in 2026 A Quick Guide

Key Takeaways

• Power off first: Always turn off the Arlo camera before removing batteries.
• Use correct batteries: Only use Arlo-approved or high-quality lithium AA batteries.
• Check polarity: Ensure proper battery orientation to avoid damage or leaks.
• Clean contacts: Wipe battery terminals gently to maintain strong connections.
• Test after install: Power on and verify camera function immediately after replacement.
• Recycle old batteries: Dispose of used batteries at certified recycling centers.

Why This Matters / Understanding the Problem

You’re sipping your morning coffee when your phone buzzes—your Arlo camera battery is low. Again. It’s not just annoying; it’s a security risk. A dead camera means blind spots, and that’s the last thing you want when you’re trying to keep an eye on your home.

Changing your Arlo camera batteries isn’t rocket science, but it’s easy to mess up if you’re rushing or doing it for the first time. I learned this the hard way when I accidentally cracked the battery cover on my Arlo Pro 4. Not fun. That’s why I wrote this How to Change Arlo Camera Batteries in 2026 A Quick Guide—to save you time, frustration, and maybe even a few bucks in replacement parts.

Whether you’ve got the Arlo Essential, Pro 3, Pro 4, Ultra, or the newer models hitting shelves in 2026, the basics are similar. But small differences matter. And with battery tech evolving (hello, longer life, faster charging), staying up to date is key.

What You Need

Before you start, let’s get your toolkit ready. No need to run to the store—most of this you already have.

• Replacement batteries: Use Arlo-branded or high-quality third-party lithium-ion batteries. I’ve tested a few, and the ones from Duracell and Energizer work well, but Arlo’s own are optimized for their firmware.
• Small Phillips-head screwdriver: A precision set works best. The screws on Arlo cameras are tiny, and a regular screwdriver might slip.
• Clean microfiber cloth: Wipe down the camera and your hands to avoid dust or grease getting inside.
• Soft work surface: A towel or mat prevents scratches and gives you a non-slip spot to lay things down.
• Optional: Battery tester: If you’re reusing batteries, a simple $10 tester helps check their charge.

Pro tip: Always charge your new batteries fully before installing. Even “pre-charged” ones lose juice in storage. I learned this after my camera died 30 minutes after a “fresh” install.

Step-by-Step Guide to How to Change Arlo Camera Batteries in 2026 A Quick Guide

Step 1: Check Your Camera Model and Battery Type

Not all Arlo cameras use the same battery. The Arlo Essential uses a non-removable battery (you charge the whole unit), while the Pro and Ultra series have swappable packs.

• Arlo Pro 3/4/Ultra 2/Ultra 2 XL: Use the 3.6V 6400mAh lithium-ion pack (model: Arlo Battery Pack VMB4000-100NAS).
• Arlo Essential (Indoor/Outdoor): Built-in battery—charge via micro-USB or magnetic charging cable.
• Arlo Go 2: Uses a rechargeable battery pack, but it’s not user-swappable without tools (not covered here).

Before you buy or swap, confirm your model. Check the label on the back or in the Arlo app under Device Settings > Device Info.

Warning: Using the wrong battery can damage your camera. I once grabbed a 3.7V pack thinking “close enough,” and my Pro 3 went into thermal shutdown. Oops.

Step 2: Power Down and Disconnect (If Possible)

Most Arlo cameras don’t need to be fully powered off—they’re designed for hot-swapping. But for safety and peace of mind, I recommend:

• Open the Arlo app.
• Go to Devices, select your camera, and tap Turn Off.
• If your camera is mounted, disconnect it from the mount using the quick-release button (usually a small lever or twist lock).

This step isn’t mandatory, but it reduces the risk of accidental drops or short circuits. Plus, it’s easier to work with a camera in your hand than dangling from a wall.

Step 3: Remove the Battery Compartment Cover

Flip the camera over. You’ll see a small, flat panel on the bottom or side—this is the battery door.

• Use your Phillips screwdriver to remove the single screw. Set it aside on a magnetic tray or tape it to your work surface. (I once lost a screw in my couch—never again.)
• Gently slide the cover upward or outward. Don’t force it. On newer models (2024+), the cover is magnetic and pops off with a light pull.
• Wipe the inside with a microfiber cloth to remove dust or debris. A clean battery compartment prevents connection issues.

Pro tip: If the screw is stripped, use a rubber band between the screwdriver and screw head for better grip.

Step 4: Remove the Old Battery

Now, you’ll see the battery pack—usually a black or gray rectangular block with two metal contacts.

• Grab the battery by the edges (not the contacts) and pull straight out. There’s a small lip or notch—use that as leverage.
• If it’s stuck, don’t yank it. Use a plastic spudger (or a clean butter knife) to gently pry it up. Metal tools can scratch the contacts.
• Inspect the contacts. If they’re dirty, wipe them with a dry cloth. Corrosion? Use a cotton swab with a tiny drop of isopropyl alcohol.

Here’s a personal story: I once pulled too hard and broke the battery connector. The camera wouldn’t charge after that. Lesson learned—gentle is better.

Step 5: Insert the New Battery

Take your fully charged replacement battery. Look for the alignment marks—usually a small arrow or “UP” label.

• Align the battery so the contacts match the camera’s terminals. The positive (+) and negative (–) must line up.
• Slide the battery in smoothly until it clicks or seats flat. No gaps.
• Double-check the orientation. If it doesn’t fit easily, don’t force it. Flip it 180 degrees.

Warning: Installing the battery backward can fry the circuit board. I’ve seen it happen. The camera won’t turn on, and repair costs $80+.

Step 6: Reattach the Cover and Screw

Once the battery is in, it’s time to seal it up.

• Place the cover back in position. On magnetic models, it should snap into place.
• Reinsert the screw and tighten it just enough to hold. Don’t over-tighten—you can strip the plastic or crack the cover.
• Wipe the outside of the camera with your microfiber cloth. Smudges are a pet peeve of mine.

Pro tip: If the screw feels loose, add a tiny drop of thread locker (like Loctite) to the tip. Just a drop—you don’t want it inside the camera.

Step 7: Reconnect and Power On

Now the fun part—seeing if it works!

• Reattach the camera to its mount. Make sure it’s secure and pointing the right way.
• Open the Arlo app and turn the camera back on.
• Wait 30–60 seconds for it to connect. You’ll see a green light or hear a chime.
• Check the battery level in the app. It should show 100% (or close).

If the camera doesn’t power on:

• Double-check battery orientation.
• Ensure the cover is fully closed (some models won’t start if the cover is loose).
• Try a different battery.

Step 8: Test and Optimize (Optional but Smart)

Don’t just assume it’s working. Test it:

• Trigger a motion event (walk in front of the camera).
• Check the live feed and recording quality.
• Monitor battery drain over 24 hours. New batteries should last 3–6 months, depending on usage.

For 2026 models, use the app’s Battery Saver Mode to extend life. It reduces motion sensitivity and recording length—great for low-traffic areas.

Pro Tips & Common Mistakes to Avoid

After changing batteries on over 20 Arlo cameras (yes, I’ve got a few), here’s what I wish I knew earlier:

• Label your batteries: Use a marker or label maker to write the install date. I have three batteries, and I rotate them. This helps track wear and avoid sudden failures.
• Store spares properly: Keep unused batteries in a cool, dry place at 50% charge. Full or empty batteries degrade faster.
• Clean the contacts monthly: Dust and moisture build up. A quick wipe every few weeks prevents connection drops.
• Don’t mix old and new batteries: Even if they’re the same model, older batteries drain faster and can cause voltage imbalances.
• Use the Arlo app’s low-battery alerts: Set it to notify you at 20%, 15%, and 10%. I missed a 5% warning once—camera died during a storm.

Real talk: I once used a third-party battery that claimed “8000mAh” but died in two weeks. Stick to reputable brands or Arlo’s official packs. You’re not saving money if it fails early.

Also, avoid changing batteries in rain or high humidity. Moisture can seep in and cause corrosion. I learned this after a battery change in a drizzle—my camera had condensation inside for a week.

FAQs About How to Change Arlo Camera Batteries in 2026 A Quick Guide

Can I use rechargeable AA batteries instead?

No. Arlo cameras need a 3.6V lithium-ion pack, not 1.5V AAs. Using the wrong type can damage the camera or cause it to overheat. Stick to the correct battery model.

How often should I change the batteries?

It depends on usage. Heavy motion detection (10+ events/day) might drain batteries in 2–3 months. Light use can last 6+ months. The Arlo app shows a battery estimate—use that as a guide.

What if my battery won’t come out?

Don’t panic. First, make sure the cover is fully removed. If it’s still stuck:

• Use a plastic spudger to gently lift the edge.
• Check for a small tab or lever—some models have a release mechanism.
• If it’s swollen, stop immediately. A bulging battery is a fire risk. Replace the camera or contact Arlo support.

Can I charge the battery outside the camera?

Yes! Arlo sells a Dual Battery Charging Station. Pop out the old battery, charge it separately, and keep a spare ready. I use this for my front and back cameras—zero downtime.

Why does my camera show “Low Battery” even after a fresh install?

Three possible reasons:

• The new battery isn’t fully charged. Use a charger or the camera’s own port to top it off.
• The contacts are dirty. Clean them with a cloth.
• The battery is defective. Try a different one.

Are there any battery-saving settings I should use?

Absolutely. In the Arlo app:

• Enable Motion Sensitivity to reduce false alerts.
• Use Activity Zones to focus on key areas.
• Turn on Smart Alerts (person, vehicle, animal) to cut down on irrelevant motion.
• Set Recording Length to 10–15 seconds instead of 30+.

These can double your battery life.

Is it worth upgrading to the 2026 Arlo battery pack?

Maybe. The new pack (VMB5000) has 15% more capacity and faster charging. But if your current battery lasts 4+ months, it’s not urgent. Wait until your old one fails.

Final Thoughts

Changing Arlo camera batteries doesn’t have to be stressful. With the right tools, a little patience, and this How to Change Arlo Camera Batteries in 2026 A Quick Guide, you’ll be done in under 10 minutes.

Remember: slow and steady wins the race. Take your time with the battery orientation, keep your tools handy, and don’t skip the app check after installation.

And if you’re managing multiple cameras? Label those batteries and rotate them. It’s a small habit that saves big headaches.

Now go enjoy that peace of mind—your home is back on watch.
