In this guide, I’ll walk you through everything you need to know about Arlo camera batteries—from how many each model uses to how to extend their life. Think of this as a friendly chat over coffee, where we solve your Arlo battery woes together.

Understanding Arlo Camera Models and Their Battery Needs

Not All Arlo Cameras Are Created Equal

Arlo offers a wide range of security cameras, from the compact Arlo Essential to the high-end Arlo Pro 4. Each model has different power needs, so the number and type of batteries vary. Let’s break it down by popular models:

• Arlo Essential (Indoor/Outdoor): Uses a single rechargeable 2,440 mAh lithium-ion battery.
• Arlo Pro 3/4: Also uses one 2,440 mAh rechargeable battery, but with improved efficiency.
• Arlo Ultra 2: Requires a single 3,600 mAh high-capacity battery for 4K video recording.
• Arlo Go (LTE): Uses one 3,600 mAh battery, but drains faster due to cellular connectivity.
• Arlo Video Doorbell (Wireless): Uses one 3,600 mAh battery (not interchangeable with other models).

Rechargeable vs. Disposable: Why It Matters

Unlike older security cameras that used AA or AAA batteries, most Arlo models use proprietary rechargeable batteries. This means you can’t just swap in store-bought batteries. While this might feel limiting, it’s actually a design choice for better performance and weather resistance. For example, the Arlo Pro 3 battery is sealed in a water-resistant casing—something standard batteries can’t offer.

Here’s a pro tip: always keep a spare battery on hand. If your camera’s battery dies while you’re on vacation, you’re out of luck unless you have a backup. I learned this the hard way when my backyard camera went dark during a storm. Now I keep two extra batteries charged and ready.

Special Cases: Wired vs. Battery-Powered Models

Some Arlo cameras, like the Arlo Essential Wired or the Arlo Pro 4 with a solar panel, don’t rely solely on batteries. The wired models plug directly into a power source, while solar panels trickle-charge the battery. This is a game-changer for reducing battery swaps. For instance, my Arlo Pro 4 with a solar panel has gone six months without needing a manual charge. But if you’re in a shaded area or a place with long winters, solar may not be enough—so batteries are still essential.

How Long Do Arlo Batteries Last? Real-World Performance

Battery Life by Model: What to Expect

Arlo advertises battery life in “months,” but real-world performance depends on usage. Here’s a rough breakdown:

• Arlo Essential: 1–2 months (with moderate activity).
• Arlo Pro 3/4: 2–3 months (with 20–30 motion events per day).
• Arlo Ultra 2: 1–2 months (due to 4K recording and spotlight usage).
• Arlo Go: 1–3 months (varies widely with LTE signal strength).

For example, my Arlo Pro 3 in the front yard (with frequent mail deliveries) lasts about 6 weeks. But my Arlo Essential in the garage (fewer triggers) goes 3 months between charges. The key is motion activity—more alerts = faster drain.

What Drains Your Battery Faster?

Several factors can shorten battery life:

• Motion sensitivity: If your camera records every leaf blowing in the wind, the battery dies faster.
• Night vision: Infrared LEDs use extra power, especially in pitch-black areas.
• Spotlight/color night vision: The Ultra 2’s spotlight can cut battery life in half if used often.
• Extreme temperatures: Batteries drain faster in cold weather (below 32°F) or heat (above 104°F).
• Wi-Fi/Cellular signal: A weak connection forces the camera to work harder, using more power.

I once had an Arlo Go in a rural area with spotty LTE. The battery lasted only 3 weeks because it was constantly searching for signal. After switching to Wi-Fi, it lasted 2 months.

How to Check Battery Life in the Arlo App

The Arlo app shows battery percentage under each camera’s settings. But here’s a lesser-known trick: enable “Battery Saver” mode (found in camera settings). This reduces video resolution and motion detection range to extend battery life. I use it during winter when my solar panel isn’t getting enough sun.

Tips to Extend Your Arlo Camera’s Battery Life

Optimize Motion Detection Settings

Not all motion needs to be recorded. Use the Arlo app to:

• Create activity zones: Exclude areas like busy streets or swaying trees.
• Adjust sensitivity: Lower sensitivity for less important areas (e.g., backyard vs. front door).
• Set schedules: Turn off motion detection at night if you have outdoor lighting.

For example, I disabled motion detection on my driveway camera between 10 PM–6 AM. Battery life increased by 40%.

Use Solar Panels or Wired Options

If you’re tired of battery swaps, consider:

• Arlo Solar Panel: Trickle-charges the battery. Works best in sunny areas (6+ hours of direct light).
• Arlo Pro 4 Wired: Plugs into an outdoor outlet. No battery needed (but requires professional installation).

My Arlo Ultra 2 with a solar panel hasn’t needed a manual charge in 5 months. But if you live in Seattle (like my cousin), solar may only give you a 30% boost due to limited sunlight.

Store Batteries Properly

Rechargeable batteries degrade over time. To prolong their life:

• Charge them to 80% before storing (not 100%).
• Keep them in a cool, dry place (not in direct sunlight).
• Recharge every 3 months if unused.

I once left a battery in a drawer for a year. When I finally used it, it lasted only 2 weeks instead of the usual 3 months. Lesson learned!

Charging Your Arlo Batteries: Best Practices

How to Charge Arlo Batteries

Arlo batteries come with a USB charging cable (or use the Arlo Solar Panel). Here’s how to charge them properly:

• Step 1: Remove the battery from the camera (use the release button).
• Step 2: Plug the USB cable into a wall adapter or computer.
• Step 3: Wait for the LED to turn solid green (usually 2–4 hours).

Avoid charging in extreme temperatures. I once left a battery charging in my car on a hot day. It swelled up and became unusable. Not worth the risk!

Fast Charging vs. Slow Charging: What’s Better?

Arlo batteries support fast charging (via 5V/2A adapters), but slow charging (5V/1A) is gentler on the battery. I use a slow charger for my spare batteries and a fast one when I need a quick top-up.

Troubleshooting Charging Issues

If your battery isn’t charging:

• Try a different USB cable or power source.
• Clean the battery contacts with a cotton swab.
• Reset the camera (press the sync button for 10 seconds).

My Arlo Pro 3 battery stopped charging once. A quick reset fixed it—no need to buy a replacement.

Replacing Your Arlo Battery: When and How

When to Replace an Arlo Battery

Batteries degrade after 2–3 years. Signs it’s time to replace:

• Battery life drops below 50% of original.
• Camera shuts down unexpectedly.
• Battery won’t hold a charge.

I replaced my 4-year-old Arlo Pro 3 battery last year. The new one lasts 3 months instead of 1.5—worth every penny!

Where to Buy Genuine Arlo Batteries

Always buy official Arlo batteries (sold on Arlo’s website or Amazon). Third-party batteries may damage your camera. I once tried a cheap knockoff—it overheated and fried the camera’s circuit board. Oops.

DIY Battery Replacement Guide

Replacing a battery is easy:

• Step 1: Power off the camera.
• Step 2: Press the release button and pull out the old battery.
• Step 3: Insert the new battery until it clicks.
• Step 4: Power on the camera and sync it via the app.

No tools required—just 2 minutes of your time.
