How to Change the Battery in an Arlo Camera 2026 Guide

Key Takeaways

• Power off the camera first to avoid damage during battery replacement.
• Use only Arlo-approved batteries for optimal performance and safety.
• Remove the battery cover carefully to prevent breaking the latch mechanism.
• Check for corrosion or debris in the battery compartment before inserting new cells.
• Fully charge batteries before use to maximize camera runtime and efficiency.
• Reattach the cover securely to ensure weather resistance and proper function.

Why This Matters / Understanding the Problem

You’re sipping coffee, checking your phone, and—uh-oh—the Arlo app just pinged you: “Low battery on Front Door Camera.” Again.

It’s frustrating. You installed these sleek outdoor cameras to feel safe, not to play battery detective every few months. But here’s the thing: knowing how to change the battery in an Arlo camera 2026 guide isn’t just about swapping cells. It’s about keeping your home secure, avoiding false alarms, and saving time (and money) on replacements.

I’ve been there. Last winter, my backyard camera died mid-snowstorm because I ignored the warning. The next day, I spent 20 minutes digging it out of a snowbank just to find a corroded battery compartment. Not fun. That’s when I learned: a little prep goes a long way.

Whether you’re using the Arlo Pro 5, Ultra, Essential, or any 2026 model, the process is similar—but with subtle differences that matter. This guide walks you through the how to change the battery in an Arlo camera 2026 guide with real-world tips, so you avoid my mistakes and keep your system running smoothly.

What You Need

Before you start, let’s gather the essentials. Nothing’s worse than halfway through a fix and realizing you’re missing a tool. Here’s your checklist:

• Replacement batteries: Arlo-specific rechargeable lithium-ion packs (model depends on your camera—check the back label). I recommend buying extras; they’re cheaper in packs.
• Micro-USB or USB-C cable: For charging. Some 2026 models use USB-C now—verify your camera’s port.
• Small Phillips screwdriver (if needed): Older models (Pro 3/4) need a screwdriver to open the battery door. Newer ones (Pro 5/Ultra 2) have magnetic or slide-out trays.
• Clean microfiber cloth: To wipe dust or moisture from the camera body.
• Optional: Silicone lubricant: For stubborn battery doors (more on this later).

Pro Tip: Always charge your new battery fully before installing. Arlo batteries ship at 30-50% charge, and a fresh charge ensures optimal performance right away.

Step-by-Step Guide to How to Change the Battery in an Arlo Camera 2026 Guide

Step 1: Check the App for Battery Status and Camera Model

Open the Arlo app and tap the camera showing the low battery alert. Look at the battery icon—if it’s below 10%, it’s time to act. But first, confirm your camera model. The app shows this under “Device Settings” > “About.”

Why this matters: Arlo Pro 5S uses a different battery than the Essential Outdoor. Using the wrong one? It won’t fit—or worse, could damage the camera.

While you’re in the app, arm your other cameras (if you have multiple) so your home stays covered during the swap.

Step 2: Power Down the Camera (If Required)

Most 2026 Arlo models (Pro 5, Ultra 2, Essential 2) are designed for hot-swapping—meaning you can change the battery without powering down. The camera stays online for about 30 seconds after removing the old battery.

But if you’re using an older model (Pro 3/4) or feel uneasy, tap “Turn Off” in the app first. This prevents any glitches during the process.

Warning: Don’t force the battery door open. If it’s stuck, it might have a screw or moisture lock. Check the manual or our “Common Mistakes” section below.

Step 3: Remove the Camera from Its Mount

Most Arlo cameras use a magnetic or quick-release mount. Here’s how to detach safely:

• Magnetic mount (Pro 5/Ultra 2): Gently pull the camera straight down. The magnet holds it securely, so a firm tug is fine—but don’t yank.
• Screw-in mount (older models): Unscrew the base counterclockwise. I keep a small tool in my outdoor toolbox for this.
• Essential series: These have a clip-on design. Press the release tab on the side and slide the camera up.

Pro tip: Lay the camera on a soft surface (like a towel) to avoid scratches. I once dropped mine on concrete—still works, but the lens has a tiny chip now.

Step 4: Open the Battery Compartment

This is where things vary by model:

• Arlo Pro 5/Ultra 2 (2026 models): Look for a small notch on the bottom edge. Use your fingernail or a plastic spudger to gently slide the battery tray out. It’s magnetic, so it pops out easily.
• Arlo Pro 3/4: Use a Phillips screwdriver to remove the single screw on the back. Slide the door open. Watch for the tiny rubber gasket—don’t lose it!
• Arlo Essential: Twist the base counterclockwise. The battery is inside the stand, not the camera body.

If the door is stuck, don’t panic. Try these fixes:

• Spray a drop of silicone lubricant on the hinges (not the battery contacts!).
• Wipe away dust or moisture with a dry cloth. Humidity can cause gaskets to swell.

Step 5: Remove the Old Battery

Pull the battery straight out. It’s held by a small clip or magnetic plate. If it’s tight, wiggle it slightly—don’t pull on the wires (if you see any). Older models have a ribbon cable; newer ones use a snap-in connector.

Inspect the old battery:

• If it’s swollen or leaking, place it in a sealed plastic bag. Never throw it in the trash. Take it to a battery recycling center.
• If it’s just old, charge it fully and keep it as a spare (Arlo batteries last 2-3 years with care).

Personal Insight: I once found mold inside a battery compartment after a heavy rain. Now I check the gasket every swap. A $5 silicone sealant kit saved me from buying a new camera.

Step 6: Insert the New Battery

Align the new battery with the contacts (the metal strips inside). Push it in until it clicks or sits flush. For magnetic trays, the battery snaps into place. For older models, ensure the ribbon cable is seated properly—no folds or kinks.

Double-check the orientation. The battery’s label should face the same way as the old one. If it’s backwards, the camera won’t power on.

Step 7: Reassemble and Test

Reverse the steps to close the camera:

• Slide the tray back in (Pro 5/Ultra 2).
• Reattach the door and screw it tight (Pro 3/4).
• Twist the base clockwise (Essential).

Now, reattach the camera to its mount. The magnet should click into place. Open the Arlo app and check:

• The battery icon should show 100% (if fully charged).
• The camera should reconnect within 30 seconds.
• Run a live view to test the feed.

If the camera doesn’t power on:

• Wait 1 minute—sometimes it needs to boot.
• Check the battery orientation again.
• Restart the camera via the app (Settings > Restart Device).

Step 8: Charge the Old Battery (If Reusable)

Place the old battery in a charger. I use the Arlo Dual Charging Station—it charges two at once and shows progress via LED lights. Avoid cheap third-party chargers; they can overheat batteries.

Store spare batteries in a cool, dry place. I keep mine in an anti-static bag in my garage toolbox.

Pro Tips & Common Mistakes to Avoid

After fixing dozens of Arlo cameras, here’s what I’ve learned the hard way:

• Mistake #1: Ignoring the gasket. That tiny rubber ring around the battery door keeps moisture out. If it’s cracked or missing, your camera will fail in rain. Replace it with a generic O-ring from a hardware store if needed.
• Mistake #2: Using non-Arlo batteries. Third-party packs might be cheaper, but they often don’t fit snugly or overheat. Stick to Arlo or certified brands like Wasabi Power.
• Mistake #3: Forgetting to charge the new battery first. A “new” battery at 30% won’t last long. Always charge it fully before install.
• Pro Tip: Label your batteries. I use a label maker to mark each battery with its install date. This helps track lifespan and spot underperformers.
• Pro Tip: Schedule battery swaps. I set a phone reminder every 4 months (even if batteries aren’t low). It’s easier to swap one at a time than all at once.

Warning: Never charge a battery while it’s in the camera. Remove it first. Charging inside can cause overheating—especially in hot weather.

FAQs About How to Change the Battery in an Arlo Camera 2026 Guide

Q: How long do Arlo batteries last?
A: Typically 3-6 months, but it depends on usage. My front door camera (motion-activated 20+ times/day) lasts 3 months. My garage camera (5 triggers/week) goes 6 months. Cold weather also drains batteries faster—expect 20-30% shorter life in winter.

Q: Can I use a power adapter instead of batteries?
A: Yes! Many Arlo models support continuous power via a solar panel or AC adapter. The Arlo Solar Panel (for Pro 3/4/5) is a great option. But if you’re using the how to change the battery in an Arlo camera 2026 guide for a model without solar support (like Essential), batteries are your only option.

Q: Why does my camera show “Low Battery” even after a swap?
A: Three reasons: 1) The new battery isn’t fully charged. 2) The battery isn’t seated properly—reopen and check. 3) The camera’s firmware needs an update. Go to Settings > Device Info > Update Firmware.

Q: Are Arlo batteries waterproof?
A: The camera is IP65-rated (water-resistant), but the battery itself isn’t. If the battery compartment seal is damaged, moisture can corrode the contacts. Always check the gasket after heavy rain.

Q: Can I recycle old Arlo batteries?
A: Absolutely. Arlo partners with Call2Recycle. Drop them at Home Depot, Best Buy, or a local recycling center. Never incinerate or puncture batteries—they can explode.

Q: What if my camera won’t power on after the swap?
A: Try a “hard reset”: Remove the battery, wait 10 seconds, reinsert it. If it still doesn’t work, the battery might be defective. Contact Arlo support—they often send a free replacement.

Q: Do all Arlo cameras use the same battery?
A: No! The Arlo Pro 5 uses a 1800mAh battery, while the Essential uses a 2500mAh pack. Check your camera’s label or the Arlo app for the exact model.
