The Arlo Pro series is one of the most popular lines, known for its weather resistance and high-definition video. Here’s the battery breakdown:

• Arlo Pro 2 and Pro 3: Each camera uses two CR123A lithium batteries. These are non-rechargeable, so you’ll need to replace them when they die.
• Arlo Pro 4 and Pro 5S: These models come with a rechargeable lithium-ion battery (model: Arlo Rechargeable Battery Pack). You can charge it via a micro-USB or magnetic charging cable.

Pro Tip: If you own a Pro 4 or 5S, always keep a spare battery charged. Swapping batteries takes seconds, and it keeps your camera online during charging.

Arlo Ultra and Ultra 2

The Arlo Ultra series is the premium line, offering 4K video and advanced AI features. These cameras use:

• One rechargeable lithium-ion battery (included). The battery is larger than Pro 4/5S models, offering longer life.
• Optional solar panel charger (sold separately) to keep the battery topped up.

Real-World Example: A friend with an Ultra 2 in her backyard uses the solar panel and only charges the battery once every 6 weeks—even during winter.

Arlo Essential Series (Indoor, Outdoor, Wire-Free)

The budget-friendly Essential line simplifies power needs:

• Arlo Essential Wire-Free: Uses two CR123A batteries (non-rechargeable).
• Arlo Essential Indoor: Plugs into a wall outlet (no batteries needed).
• Arlo Essential Outdoor (Wired): Requires a power adapter (no batteries).

Key Takeaway: The Essential line trades flexibility for simplicity. If you want wire-free convenience, you’ll need to manage batteries.

Arlo Go (LTE Mobile Camera)

The Arlo Go is designed for remote locations without Wi-Fi. It uses:

• One rechargeable lithium-ion battery (similar to Pro 4/5S).
• Supports solar charging (with a compatible panel).

Note: The Arlo Go’s battery life is shorter due to LTE usage. Expect 2–4 months per charge, depending on activity.

Battery Life: How Long Do Arlo Batteries Last?

Battery life isn’t one-size-fits-all. It depends on your camera model, usage, and environment. Let’s explore the factors that affect runtime and how to estimate your needs.

Average Battery Lifespan by Model

Here’s a rough estimate of how long batteries last under normal conditions:

• Arlo Pro 2/3 (CR123A): 3–6 months
• Arlo Pro 4/5S (Rechargeable): 2–3 months
• Arlo Ultra/Ultra 2 (Rechargeable): 3–5 months
• Arlo Essential Wire-Free (CR123A): 2–4 months
• Arlo Go (Rechargeable): 2–4 months

Why the variation? These numbers assume moderate activity (10–20 motion events per day). If your camera triggers constantly, battery life drops fast.

Factors That Impact Battery Life

Several variables shorten or extend battery life:

• Motion Activity: Cameras that record frequently drain batteries faster. A camera pointed at a busy street will use more power than one in a quiet backyard.
• Temperature: Lithium batteries perform poorly in extreme cold or heat. Below freezing? Expect 30–50% less runtime.
• Video Quality: 4K (Ultra) uses more power than 1080p (Pro). Lowering resolution can extend life.
• Wi-Fi/Network Signal: Weak connections force the camera to work harder, increasing power draw.
• Night Vision: Infrared LEDs consume extra power. Cameras with 24/7 night vision will drain faster.

Practical Tip: In winter, move your camera to a sheltered area (e.g., under an eave) to protect it from snow and wind. This helps maintain battery efficiency.

How to Check Battery Life in the Arlo App

The Arlo app shows real-time battery percentage. To check:

1. Open the Arlo app and tap your camera.
2. Look for the battery icon (usually in the top-right).
3. Tap “Device Settings” > “Battery” for detailed stats.

The app also sends low-battery alerts. Set up notifications in Settings > Alerts to avoid surprises.

Battery Types: Rechargeable vs. Disposable

Choosing the right battery type impacts cost, convenience, and sustainability. Let’s compare your options.

Rechargeable Lithium-Ion Batteries

Used in Pro 4, Pro 5S, Ultra, and Go models, these batteries are:

• Pros: Cost-effective long-term (no need to buy replacements), eco-friendly, easy to swap.
• Cons: Require charging downtime (1–2 hours), degrade over time (last ~2–3 years).

Pro Tip: Buy a second rechargeable battery. When one dies, swap it in immediately. Charge the dead one overnight.

Disposable CR123A Batteries

Used in Pro 2/3 and Essential Wire-Free, these are:

• Pros: No charging needed (great for remote locations), widely available.
• Cons: Ongoing cost (a 4-pack costs $15–$25), less eco-friendly, must be replaced entirely.

Cost Example: If your Pro 3 uses 4 CR123A batteries per year, you’ll spend $75–$125 annually. Over 3 years, that’s $225–$375—more than a spare rechargeable battery.

Third-Party Batteries: Are They Worth It?

Some brands sell generic rechargeable batteries for Arlo. While cheaper, they often:

• Have lower capacity (shorter life).
• Risk damaging your camera (poor voltage regulation).

Verdict: Stick to Arlo-branded batteries. The reliability is worth the extra cost.

Maximizing Battery Life: Tips and Tricks

Want to make your batteries last longer? These strategies can extend runtime by 20–50%.

Adjust Motion Detection Settings

Motion triggers are the #1 battery drain. Optimize them by:

• Reducing sensitivity: Lower the motion detection slider in the app.
• Using activity zones: Only record in high-risk areas (e.g., your front door, not the street).
• Scheduling recordings: Set cameras to record only during high-activity hours (e.g., 6 AM–9 PM).

Example: A user with a backyard camera reduced motion events from 50 to 10 per day by adjusting zones. Battery life jumped from 3 to 5 months.

Optimize Video Settings

Lower video quality and frame rate to save power:

• Switch from 4K (Ultra) to 1080p or 720p.
• Reduce the frame rate from 30fps to 15fps.

Note: This is ideal for areas where ultra-crisp video isn’t critical (e.g., a side yard).

Use Solar Panels (For Rechargeable Models)

Solar panels eliminate the need for manual charging. They work with:

• Arlo Ultra/Ultra 2
• Arlo Pro 4/5S
• Arlo Go

Real-World Test: A user with an Ultra 2 and solar panel hasn’t charged the battery in 8 months. The panel keeps it at 80–100% year-round.

Keep Cameras in Moderate Temperatures

Store spare batteries in a cool, dry place. Avoid leaving cameras in direct sunlight or freezing conditions.
