How Many Batteries Arlo Camera Uses: A Complete Guide

Imagine this: you’ve just set up your brand-new Arlo security system. The cameras are mounted, the app is synced, and you’re feeling like a home security pro. Then—bam—a low battery notification pops up. You panic, wondering: How many batteries do Arlo cameras use? Are they rechargeable? How long will they last? And why didn’t the box mention this?

If you’ve ever found yourself staring at an Arlo camera, battery cover in hand, unsure where to go from there, you’re not alone. Arlo cameras are popular for their wireless convenience, sleek design, and smart features. But their battery usage can be a bit of a mystery—especially when you’re juggling multiple cameras around your home or property. Whether you’re a first-time Arlo user or upgrading your existing setup, understanding battery needs is key to keeping your system running smoothly. In this guide, I’ll walk you through everything you need to know—from battery types and counts to lifespan tips and real-world examples—so you can stay powered up and protected.

Understanding Arlo Camera Models and Their Battery Requirements

Before we dive into numbers, it’s important to know that not all Arlo cameras use the same batteries. Arlo offers a range of models, from indoor-only units to rugged outdoor cameras with advanced features. Each has its own battery specs, and knowing the difference can save you time, money, and frustration.

Arlo Essential Series (Indoor & Outdoor)

The Arlo Essential Indoor and Outdoor cameras are among the most popular entry-level options. These are fully wireless and rely on rechargeable lithium-ion batteries. Each camera uses one 3.7V, 2,500mAh battery. That might not sound like a lot, but thanks to Arlo’s efficient power management, these batteries can last weeks—even months—depending on usage.

For example, I installed an Essential Outdoor in my backyard facing the gate. With moderate motion detection (about 10–15 clips per day), the battery lasted about 8 weeks before needing a recharge. That’s pretty impressive for a camera that’s always on.

Arlo Pro Series (Pro 3, Pro 4, Pro 5)

The Pro line is where things get more advanced—and more power-hungry. The Arlo Pro 3, Pro 4, and Pro 5 all use a custom 3.85V, 4,800mAh rechargeable battery. This larger capacity supports features like 2K HDR video, color night vision, and extended recording times.

Each Pro camera still uses one battery per unit, but the battery itself is bigger and lasts longer. In my experience with the Pro 4, I got around 10–12 weeks of use with similar motion activity. The larger battery also recharges faster when plugged into a solar panel or wall charger.

Arlo Ultra and Ultra 2

These premium models pack 4K video, a spotlight, and a siren. Power demands are higher, so Arlo equips them with a 5,200mAh battery. Again, it’s one battery per camera, but the larger capacity helps offset the energy needed for high-resolution streaming and active deterrence features.

I tested an Ultra 2 in my front yard for three months. With frequent 4K clips and the spotlight turning on nightly, the battery still lasted about 9 weeks. Not bad for a camera that’s essentially a mini surveillance studio.

Arlo Go and Arlo Go 2 (LTE Cameras)

These are unique because they’re designed for remote areas without Wi-Fi. The Arlo Go uses a 6,500mAh battery, while the Go 2 bumps it up to 7,000mAh. These batteries are built to last longer due to the constant cellular connection, which drains power faster than Wi-Fi.

For instance, a friend of mine uses an Arlo Go 2 to monitor a cabin 20 miles from town. With LTE and moderate motion, the battery lasted 6–7 weeks—a solid result considering the constant data transmission.

How Long Do Arlo Batteries Last in Real-World Use?

Now that we know the specs, let’s talk real-world battery life. Arlo’s official estimates can be optimistic, but actual performance depends on several factors. Think of it like your smartphone: battery life varies based on screen brightness, app usage, and background activity.

Factors That Affect Battery Life

• Motion Frequency: The more motion events, the more the camera records and streams. More clips = more battery drain. If your camera faces a busy street, expect shorter battery life.
• Video Resolution: Higher resolution (like 4K) uses more power. Switching to 1080p or 720p in the Arlo app can extend battery life by 20–30%.
• Night Vision Mode: Infrared LEDs use extra power. If your camera is in a dark area with frequent motion, night vision can cut battery life in half.
• Wi-Fi Signal Strength: Weak signals force the camera to work harder to maintain connection, draining the battery faster.
• Temperature: Extreme cold (below 32°F/0°C) or heat (above 104°F/40°C) can reduce battery efficiency. I once had a camera die in winter because the cold slowed the chemical reactions inside the battery.

Real-World Battery Life Examples

Let’s look at some real scenarios based on my own setup and feedback from Arlo users:

• Low Activity (5–10 clips/day): 10–14 weeks on Pro 4, 12+ weeks on Essential
• Medium Activity (15–25 clips/day): 6–8 weeks on Pro 4, 7–9 weeks on Essential
• High Activity (30+ clips/day): 3–5 weeks on Pro 4, 4–6 weeks on Essential
• 4K Recording (Ultra 2): 6–8 weeks with mixed activity
• LTE (Go 2): 5–7 weeks with moderate use

One user shared that their Arlo Pro 3 lasted only 4 weeks because it was facing a tree that constantly triggered motion alerts in the wind. After adjusting the detection zone and enabling person detection, the battery life jumped to 9 weeks.

Pro Tip: Use Activity Zones and Smart Alerts

To maximize battery life, use Activity Zones in the Arlo app to ignore unimportant motion (like trees or street traffic). Also, enable Smart Alerts to filter out animals or vehicles if you only care about people. These small tweaks can make a big difference in how often your camera records—and how long the battery lasts.

Rechargeable vs. Disposable: Why Arlo Uses Rechargeable Batteries

You might be wondering: Why doesn’t Arlo use standard AA or AAA batteries? After all, those are easy to find and replace. The answer lies in design, performance, and user experience.

Benefits of Rechargeable Batteries

• Custom Fit: Arlo batteries are designed specifically for each camera model. This ensures a snug fit, weather resistance, and optimal power delivery.
• Long-Term Savings: While the upfront cost is higher (batteries range from $25 to $50), you avoid buying packs of disposables over time. One rechargeable battery can be charged 500+ times.
• Eco-Friendly: Rechargeables reduce e-waste. Imagine replacing 100 AA batteries a year—now you’re saving the planet one charge at a time.
• Consistent Performance: Lithium-ion batteries maintain voltage longer than alkaline disposables, which start strong but fade quickly.

Can You Use Third-Party or DIY Battery Solutions?

Technically, yes—but I wouldn’t recommend it. I tried using a third-party battery in my Pro 3, and while it fit, it lasted only 4 weeks instead of the usual 8. Worse, it overheated during charging and triggered a warning in the app.

Arlo’s batteries are calibrated to work with the camera’s power management system. Third-party options often lack the right voltage curve or safety features. Plus, using non-Arlo batteries may void your warranty.

If you’re in a pinch, you can swap batteries between cameras—just make sure they’re the same model. For example, a Pro 4 battery works in another Pro 4, but not in an Essential.

How to Charge Arlo Batteries

• Remove the battery from the camera (a quick 2-second slide-out).
• Plug into the Arlo magnetic charging cable (or a USB-C cable for newer models).
• Charge time: 4–6 hours for a full charge.
• Use a solar panel (sold separately) for continuous charging—ideal for outdoor cameras.

I keep a spare battery for each camera in my home. When one dies, I swap in the charged one and recharge the other. It’s like having a battery rotation system—simple, effective, and stress-free.

How to Extend Arlo Camera Battery Life

Let’s face it: nobody likes climbing a ladder every month to swap batteries. The good news? There are several proven ways to make your Arlo batteries last longer. Here’s how I’ve stretched mine to the max.

Optimize Video Settings

Lowering resolution and frame rate can dramatically improve battery life. In the Arlo app:

• Go to Device Settings > Video Settings
• Switch from 2K/4K to 1080p or 720p
• Reduce frame rate from 30fps to 15fps (you won’t notice the difference in most clips)

I did this on my Essential camera and gained an extra 2 weeks of battery life—without sacrificing video quality for everyday monitoring.

Use Solar Panels (Best for Outdoor Cameras)

Arlo’s 10W Solar Panel is a game-changer. It connects magnetically and keeps your camera powered all year. I installed one on my Pro 4, and after the initial charge, I haven’t touched the battery in 6 months. It’s perfect for sunny areas (6+ hours of sunlight daily).

Tip: Angle the panel toward the sun and clean it monthly to avoid dust buildup.

Schedule Recording Times

If you only need surveillance at night, use Smart Schedules in the app to turn off recording during the day. For example:

• Front yard camera: active from 6 PM to 6 AM
• Garage camera: active only on weekends

This cuts power usage by up to 50% during off-hours.

Adjust Motion Sensitivity

High sensitivity means more false alerts (like leaves or pets). In the app:

• Go to Device Settings > Motion Detection
• Lower sensitivity to “Medium” or “Low”
• Enable Person, Vehicle, or Package Detection (Pro and Ultra models)

One user reduced their camera’s motion events from 40 to 12 per day—and battery life doubled.

Keep Cameras Warm in Winter

Cold weather kills lithium-ion batteries. If you live in a cold climate:

• Install cameras under eaves or in sheltered areas
• Use a battery cover (available from Arlo) for insulation
• Bring cameras indoors during extreme cold (below 0°F)

I lost a camera in a blizzard once. Lesson learned: protect your gear!

Battery Management for Multi-Camera Arlo Systems

If you have 4, 6, or even 10 Arlo cameras, battery management becomes a full-time job—unless you plan ahead. Here’s how to stay organized and avoid unexpected outages.

Create a Battery Rotation Schedule

Label each battery with a number and track charge cycles in a simple spreadsheet or app. For example:

• Camera 1: Battery A (charged every 8 weeks)
• Camera 2: Battery B (charged every 6 weeks)
• …and so on

I use Google Keep to set reminders: “Check Camera 3 battery in 7 weeks.” This way, I never get caught off guard.

Invest in a Battery Charging Station

Arlo sells a 3-bay charging station that lets you charge multiple batteries at once. It’s a lifesaver for large setups. I keep mine on my desk and rotate batteries like clockwork.

Use the Arlo App for Battery Monitoring

The app shows battery percentage for each camera. Enable Low Battery Notifications so you’re alerted before a camera dies. You can also see:

• Estimated battery life
• Last charge date
• Power-saving mode status

One time, the app warned me a camera was at 15%—just in time to swap the battery before it shut off during a storm.
