Why This Matters / Understanding the Problem

You’ve just set up your Arlo camera—maybe it’s guarding your front porch, watching over your backyard, or keeping an eye on the garage. Everything’s working, you’re feeling secure… until the low battery alert pops up. Suddenly, that sense of safety feels shaky.

Let’s be real: no one likes being caught off guard by a dead battery. Especially when your camera is your first line of defense. That’s why knowing how to install batteries in Arlo camera 2026 guide matters. It’s not just about swapping cells—it’s about doing it right so your system stays reliable, responsive, and ready.

I learned this the hard way last winter. My outdoor camera died during a snowstorm because I rushed the battery change. The cold drained the new batteries in days. Not cool. Since then, I’ve refined my process—and now I’m sharing it with you. This How to Install Batteries in Arlo Camera 2026 Guide will help you avoid rookie mistakes and keep your cameras running smoothly, no matter the weather or season.

Whether you’re using Arlo Pro 3, Pro 4, Ultra, or the newer 2026-compatible models, this guide covers it all. And don’t worry—no tech degree required. Just a few minutes, the right tools, and a little patience.

What You Need

Before you dive in, let’s make sure you’ve got everything on hand. Nothing’s worse than halfway through a battery swap and realizing you’re missing something.

• Compatible batteries: Arlo cameras typically use CR123A lithium batteries. Some models support rechargeable Arlo-branded packs (like the Arlo Pro 4/Ultra battery), but the CR123A is the standard. Always check your model’s manual—some newer 2026 editions accept both.
• Clean microfiber cloth: For wiping down the battery compartment and contacts.
• Small flathead screwdriver (optional): Some older Arlo housings have a tiny screw securing the battery cover. Newer models are tool-free, but it’s good to have one nearby.
• Fresh, name-brand batteries: Skip the off-brand packs. I once used cheap CR123As—they lasted 10 days. Lesson learned. Go with Panasonic, Energizer, or Duracell for longer life and consistent performance.
• Indoor workspace: If your camera is outside, bring it inside to change batteries. Cold or wet conditions make handling delicate contacts risky.
• Arlo app on your phone or tablet: You’ll need this to check battery status and re-sync the camera after installation.

Pro Insight: I keep a small “Arlo battery kit” in my drawer—extra CR123As, a microfiber cloth, and a screwdriver. It’s saved me more than once when a battery died at 10 PM.

Step-by-Step Guide to How to Install Batteries in Arlo Camera 2026 Guide

Step 1: Power Down and Remove the Camera

First things first—safety. Even though Arlo cameras are low-voltage, you don’t want to risk shorting anything or dropping the camera mid-swap.

• Open the Arlo app and locate your camera in the device list.
• Tap on it and select “Remove Camera” or “Power Down” (depending on your app version). This disconnects it from the network and avoids false alerts.
• Now, physically remove the camera from its mount. Most Arlo models use a magnetic or twist-lock base. Gently pull or twist—don’t force it. If it’s stuck, wiggle it slightly while applying steady pressure.

Bring the camera indoors to a clean, dry surface. This is crucial, especially if it’s been outside. Dust, moisture, or cold can affect battery performance and contact alignment.

Warning: Never try to change batteries while the camera is mounted. It’s awkward, and you risk dropping it—or worse, damaging the mount or lens.

Step 2: Locate and Open the Battery Compartment

Now, flip the camera over. The battery compartment is usually on the back or bottom, depending on the model.

• Look for a small sliding latch or twist-off cap. On newer 2026-compatible models (like Arlo Pro 4 and Ultra), it’s a simple push-to-open latch.
• For older models (Arlo Pro 3 and earlier), you might need to slide the cover down or use a tiny screwdriver to loosen a small screw.
• Once open, you’ll see either a single battery slot (for CR123A) or a larger compartment for an Arlo rechargeable pack.

Take a moment to inspect the inside. Are the contacts clean? Is there any dust, corrosion, or moisture? If so, gently wipe them with a microfiber cloth. I once found a tiny spider web in mine—yikes.

Pro Tip: Use a cotton swab lightly dampened with isopropyl alcohol if you see corrosion. Let it dry completely before inserting batteries.

Step 3: Remove Old Batteries (or Pack)

This step is straightforward, but don’t rush it.

• If using CR123A batteries: Note their orientation (positive/negative) before removing. Most compartments have a diagram inside the cover—take a photo with your phone for reference.
• Use your fingers or a small tool to gently lift the batteries out. They’re often snug, but don’t pry too hard.
• If using an Arlo rechargeable battery pack: Simply lift it out. It’s designed for easy removal.

Dispose of old batteries responsibly. CR123A lithium batteries should go to a recycling center—don’t toss them in the trash. I keep a small “dead battery” jar in my garage until I can drop them off at Home Depot.

Common Mistake: Forgetting to check the old battery’s polarity. If you reverse the new one, the camera won’t power on—and you’ll think it’s dead.

Step 4: Insert New Batteries Correctly

Now for the main event: installing the new power source.

• For CR123A batteries: Match the polarity—positive (marked with a +) to the positive contact, negative to negative. The compartment usually has a diagram. If not, remember: the flat end is usually negative, the bump is positive.
• Slide or press the batteries in firmly but gently. You should feel a slight click or snug fit.
• For Arlo rechargeable pack: Align the contacts on the pack with those in the compartment. Push it in until it seats fully. It’s magnetic, so it’ll snap into place.

Double-check the orientation. I once reversed one battery in a dual-slot model—camera powered on, but the app showed “battery error.” Took me 10 minutes to figure it out.

Pro Tip: Use fresh batteries from the same pack and date. Mixing old and new (even if “new” is from a half-used pack) can cause uneven power distribution and faster drain.

Step 5: Reassemble and Test

Now, close the compartment securely.

• Slide the cover back into place until it clicks. If it has a screw, tighten it gently—don’t over-torque.
• Wipe the camera lens and body with a microfiber cloth. Dust on the lens can affect night vision and motion detection.
• Return the camera to its mount. Make sure it’s aligned and secure.

Open the Arlo app and go to your device list. You should see the camera reconnect automatically within a minute. If not, tap “Add Device” and follow the prompts to re-pair.

Check the battery status in the app. It should show 100% (or close to it). Also, verify that live streaming and motion alerts are working.

Warning: If the camera doesn’t power on, double-check battery orientation and contacts. Also, ensure the compartment is fully closed—some models won’t power on if the cover is loose.

Step 6: Optimize Battery Life (Bonus Step)

Installing batteries is one thing—keeping them alive is another. Here’s how to stretch their life, especially in cold climates.

• Adjust motion detection zones: In the app, limit the camera’s “active” area to high-traffic spots. Fewer false alerts = less recording = longer battery.
• Lower video quality: If you don’t need 4K, switch to 1080p. It uses less power during recording and streaming.
• Use a solar panel (if available): Arlo’s solar panel keeps the battery topped up. I use one on my backyard camera—battery stays above 80% year-round.
• Check firmware: Outdated firmware can cause battery drain. In the app, go to Settings > Device Info > Firmware and update if needed.

I once had a camera die every 3 weeks. After adjusting the motion zone and adding a solar panel, it now lasts 3 months. Small changes, big impact.

Pro Insight: Cold weather cuts lithium battery life in half. If you live in a cold region, consider bringing the camera in overnight during extreme cold snaps.

Pro Tips & Common Mistakes to Avoid

Let’s talk about the things they don’t tell you in the manual—but I wish I knew earlier.

• Don’t use alkaline batteries: CR123A is lithium-only. Alkaline won’t fit or work—and could damage the camera.
• Label your batteries: I write the install date on new batteries with a permanent marker. It helps me track lifespan and identify duds.
• Check the app regularly: The Arlo app sends low-battery alerts, but they can be delayed. I check battery levels weekly, especially in winter.
• Store spares properly: Keep extra batteries in a cool, dry place—not in the fridge or garage. Heat and humidity degrade lithium cells.
• Clean contacts every swap: A quick wipe prevents corrosion and poor connections. I do this every time, even if they look clean.

Common Mistake: Assuming all Arlo cameras use the same battery. The Arlo Go (LTE model) uses a different battery type. Always verify your model before buying.

And here’s a personal fail: I once left a camera outside during a thunderstorm while changing batteries. Rain got into the compartment. It shorted the contacts and killed the camera. Now I always bring it inside.

Also, avoid using rechargeable CR123A batteries unless they’re specifically designed for high-drain devices like Arlo. Regular NiMH rechargeables don’t deliver enough voltage and can cause erratic behavior.

One last tip: if your camera is in a hard-to-reach spot (like a high eave), consider a battery extension cable (sold separately). It lets you place the battery pack lower, making swaps easier. I use one on my garage camera—no more ladder!

FAQs About How to Install Batteries in Arlo Camera 2026 Guide

Here are the questions I get most—answered honestly, from real experience.

Q: Can I use rechargeable batteries in my Arlo camera?
A: Yes, but only if they’re Arlo-branded rechargeable packs (for Pro 4, Ultra, etc.). For CR123A slots, use lithium rechargeables rated for high-drain devices. Regular NiMH rechargeables won’t work well. I tried—camera kept shutting off mid-recording.

Q: How often do Arlo camera batteries need to be replaced?
A: Depends on usage, temperature, and settings. With moderate use (10–20 alerts/week), CR123A lasts 2–3 months. Rechargeable packs last 2–4 months. In cold weather, expect half that. I check mine every 6 weeks.

Q: Why does my Arlo camera show “low battery” after installing new ones?
A: Could be a few things: reversed polarity, dirty contacts, or a faulty battery. First, double-check the orientation. Then, clean the contacts. If it still shows low, try a different battery. I once got a bad batch from Amazon—returned them immediately.

Q: Can I charge the rechargeable battery without removing it?
A: No. The Arlo rechargeable pack must be removed and charged via USB. It takes about 3 hours. I keep a spare pack so I can swap and charge—no downtime.

Q: Is it safe to change batteries in the rain?
A: Absolutely not. Water can damage the camera and cause short circuits. Even a light drizzle is risky. Always bring the camera inside. I learned this after a close call—camera survived, but I was sweating bullets.

Q: What if my camera doesn’t power on after battery install?
A: Check the battery orientation, contacts, and compartment closure. If all looks good, try resetting the camera (hold the reset button for 10 seconds). If it still won’t power on, contact Arlo support. It might be a hardware issue.

Q: Do solar panels really extend battery life?
A: Yes—but only if it gets direct sunlight for 4–6 hours daily. Mine is on a south-facing wall and keeps the battery above 80%. If it’s shaded, it won’t help much.
