In this guide, we’ll dive deep into the battery requirements across Arlo’s lineup, share real-world tips to maximize performance, and help you avoid those “dead camera” surprises. Think of this as your friendly, no-nonsense walkthrough—like a chat with a tech-savvy neighbor who’s been through it all.

Arlo Camera Models and Their Battery Requirements

Arlo Essential Series: Simple, Efficient, and Battery-Friendly

The Arlo Essential lineup—including the Essential Spotlight, Essential XL, and Essential Indoor—is designed for simplicity and affordability. These cameras typically run on two CR123A lithium batteries. That’s it. No complex setups, no proprietary cells. Just pop in two batteries, and you’re good to go. I’ve used the Essential Spotlight for over a year, and the batteries lasted about 6 months with moderate use (around 15–20 motion events per week).

The CR123A batteries are widely available at hardware stores, online retailers, and even pharmacies. Their lithium chemistry gives them an edge over alkaline—they perform better in cold weather and have a longer shelf life. But don’t be fooled: they’re not rechargeable. If you’re using your camera frequently or in extreme temperatures, you might need replacements every 4–5 months. Pro tip: Buy them in bulk (a 12-pack on Amazon costs less than $20) and store extras in a cool, dry place to avoid leakage.

Arlo Pro Series: Power-Hungry, But Worth It

The Arlo Pro 2, Pro 3, and Pro 4 models are more advanced, featuring color night vision, two-way audio, and higher video resolution. But with great power comes greater battery needs. These cameras use a single, rechargeable 3.7V lithium-ion battery (model A-2 or A-3, depending on the version). The battery is built into the camera, so you don’t swap it—instead, you remove the entire unit and charge it via USB-C or a charging dock.

In my experience, the Pro 3’s battery lasts about 3–4 months under normal conditions. But if you live in a busy neighborhood (lots of motion triggers) or use features like 4K video or continuous recording, expect it to drop to 2 months or less. The good news? The battery is replaceable. Arlo sells replacement batteries for around $25–$30. Just make sure to get the right model—check your camera’s serial number or consult the manual.

Arlo Ultra and Ultra 2: The High-End Power Users

The Arlo Ultra and Ultra 2 are the flagship models, boasting 4K HDR, advanced AI detection, and built-in spotlights. But all that tech demands serious power. Like the Pro series, they use a single, removable 3.7V lithium-ion battery. However, the Ultra’s battery is larger (around 6,500 mAh vs. the Pro’s 4,000 mAh), which translates to longer life—typically 4–6 months with average use.

Here’s a real-world example: I installed an Ultra 2 in my backyard, facing a busy street. With 30+ motion events weekly and 4K recording enabled, the battery lasted 4.5 months. When it did die, the process was smooth—I charged it overnight and reattached it. One caveat: The Ultra’s battery is pricier (around $35–$40), so keep a spare if you don’t want downtime. Also, avoid leaving it in extreme heat (like a sunlit porch), as high temperatures degrade lithium-ion cells faster.

Arlo Go 2: The Cellular Workhorse

The Arlo Go 2 is unique—it’s a cellular camera, meaning it connects to LTE networks for remote areas without Wi-Fi. It runs on a built-in, non-removable 3.7V lithium-ion battery. Unlike other Arlo models, you can’t swap the battery. Instead, you charge the entire camera. Battery life is shorter due to cellular use: about 2–3 months with light activity, but it can drop to 1 month if you’re streaming video often or in a weak signal area.

I tested the Go 2 at a cabin with spotty Wi-Fi. The LTE connection kept it online, but the battery drained faster than expected. My fix? I bought a solar panel accessory (sold separately for $50), which extends the life significantly. If you’re using the Go 2, consider the solar option—it’s a game-changer for off-grid security.

How Battery Life Varies: Real-World Factors You Can’t Ignore

Motion Activity and Recording Settings

Battery life isn’t just about the camera—it’s about how you use it. The biggest drain? Motion-triggered recordings. Every time your camera detects motion, it wakes up, records, and sends a notification. More activity = more battery use. For example, my front-door Essential camera (facing a busy sidewalk) uses batteries 30% faster than my backyard one (facing a quiet garden).

Here’s how to optimize: Use custom activity zones in the Arlo app to ignore irrelevant motion (like passing cars or trees swaying). Also, lower the recording length from 30 seconds to 15 seconds—it saves power without sacrificing usefulness. I did this with my Pro 3, and it extended battery life by nearly a month.

Environmental Conditions: Temperature and Weather

Extreme temperatures are battery killers. Cold weather slows chemical reactions in batteries, reducing capacity. Hot weather? It accelerates degradation. I learned this the hard way when my Arlo Ultra (mounted on a sun-exposed wall) died after just 2 months in summer. The battery was cooked.

For cold climates: Use lithium batteries (they perform better than alkaline below 0°C) and install cameras in shaded areas. For hot climates: Add a small awning or use Arlo’s official weather shield. Also, avoid direct midday sun. A shaded porch or under-eave mount is ideal.

Wi-Fi Signal Strength and Connectivity

Weak Wi-Fi = more power use. Your camera constantly struggles to maintain a connection, draining the battery faster. My basement Arlo Pro 3 (with spotty Wi-Fi) had a 40% shorter battery life than my garage unit (strong signal). The fix? I added a Wi-Fi extender. Now both cameras last the same amount of time.

For cellular models (like the Go 2): Poor signal strength is even worse. The camera works harder to stay connected, using more power. Check your LTE signal in the Arlo app—if it’s weak, consider a signal booster or reposition the camera.

Feature Usage: Night Vision, Spotlights, and Audio

Features like night vision, spotlights, and two-way audio are convenient but power-hungry. Infrared LEDs for night vision use extra juice, especially in dark areas. My Arlo Essential XL (with a built-in spotlight) uses batteries 25% faster than the standard Essential.

Tip: Use motion-activated spotlights instead of always-on. Also, disable two-way audio unless you need it. I turned off audio on my backyard camera (I rarely use it), and the battery life jumped by 20%.

Pro Tips to Extend Your Arlo Camera’s Battery Life

Optimize Motion Detection Settings

The Arlo app lets you fine-tune motion sensitivity and recording triggers. Here’s what works:

• Lower sensitivity: Set it to “medium” or “low” to avoid false triggers (like leaves or shadows).
• Schedule recordings: Use “arm/disarm” schedules to disable the camera during low-risk times (e.g., when you’re home).
• Smart notifications: Enable “person detection” to filter out animals or vehicles. Fewer alerts = less battery use.

I used these settings on my Pro 4, and the battery lasted 5 months instead of 3. It’s like teaching your camera to be more efficient.

Use Solar Panels and Charging Docks

Arlo’s official solar panels (compatible with Pro 3, Pro 4, and Ultra) are worth the investment. They provide a trickle charge, keeping the battery topped off. My backyard Ultra 2, with a solar panel, has run for over a year without a manual charge. The panel costs $60, but it pays for itself in convenience.

For non-solar models: Use a charging dock. I keep a spare battery charging at all times, so I can swap it in minutes. It’s a simple system—like having a spare phone battery.

Regular Maintenance and Firmware Updates

Outdated firmware can cause battery drain. Arlo occasionally releases updates to improve efficiency. Check for updates in the app every few months. Also, clean your camera’s lens and sensors regularly. Dust or cobwebs can trigger false motion events, wasting power.

One time, a spider built a web in front of my camera, causing 20+ false triggers daily. After cleaning it, the battery life improved by 30%. A quick wipe with a microfiber cloth makes a difference.

Battery Storage and Replacement Hacks

For CR123A batteries: Store them in a plastic case, not loose in a drawer. This prevents short circuits. Also, rotate your stock—use the oldest batteries first. For rechargeable batteries: Avoid fully draining them. Lithium-ion cells last longer if kept between 20% and 80% charge.

When replacing batteries: Always power off the camera first. I once forgot and fried a Pro 3’s circuit board—$150 down the drain. Lesson learned.

Common Battery Myths and Mistakes to Avoid

Myth: “All Batteries Are the Same”

Not true. Lithium batteries (like CR123A) last longer and perform better in cold weather than alkaline. I once tried using alkaline in my Essential—it died in 2 months. Stick with lithium for Arlo cameras.

Mistake: Ignoring Low Battery Alerts

The Arlo app sends low battery alerts at 20%. Don’t ignore them. A dying battery can cause the camera to reboot, losing recordings. I set a monthly calendar reminder to check battery levels—it’s saved me from surprises.

Myth: “Rechargeable Batteries Are Always Better”

For Arlo Pro and Ultra, yes. But for the Essential series, non-rechargeable CR123A is the only option. Don’t try to use rechargeable CR123A (they have lower voltage and may damage the camera).

Mistake: Overlooking Solar Panels

Many users skip solar panels, thinking they’re unnecessary. But for remote areas or busy cameras, they’re a lifesaver. My solar-powered Ultra 2 has been running for 14 months straight—no manual charging.
