Understanding Arlo Cameras and Their Power Source

Let’s talk about one of the most common questions I hear from Arlo camera users: “Can you recharge Arlo batteries while in the camera?” If you’ve ever found yourself in the middle of a busy week, only to realize your Arlo camera is blinking red and needs a battery change, you’re not alone. I’ve been there—sitting on the couch, watching my security feed, when suddenly the low-battery alert pops up. My first thought? “Do I really need to take the camera down, pop out the battery, and charge it separately?” Sound familiar?

Arlo cameras are a popular choice for home security. They’re wireless, easy to install, and offer great video quality. But their battery-powered design brings up a big question: convenience vs. maintenance. Most Arlo models run on rechargeable batteries—either the Arlo Rechargeable Battery or third-party options like CR123A or 18650 lithium-ion cells. The real issue isn’t just about recharging; it’s about how and where you do it. Can you leave the battery in the camera while charging? Is it safe? Does it even work? Let’s dive in and find out, step by step, with real-world examples and honest insights.

How Arlo Batteries Work: The Basics

Before we answer whether you can recharge Arlo batteries while in the camera, it helps to understand how these batteries function and what models use them. Not all Arlo cameras are the same, and their power systems vary slightly depending on the model.

Types of Arlo Cameras and Their Batteries

Arlo offers several camera lines, each with different battery setups:

• Arlo Pro series (Pro 2, Pro 3, Pro 4): Uses the proprietary Arlo Rechargeable Battery (model: A-2). These are lithium-ion batteries designed specifically for Arlo Pro cameras. They’re removable and must be charged externally.
• Arlo Ultra and Ultra 2: Also use the A-2 battery, but with higher capacity and support for faster charging via USB-C.
• Arlo Essential (Indoor/Outdoor): Uses two CR123A lithium batteries. These are non-rechargeable by default, but you can swap in rechargeable CR123A batteries if you choose.
• Arlo Wire-Free (older models): Use standard 18650 lithium-ion batteries, which are widely available and often rechargeable.

So, right off the bat, the answer to “can you recharge Arlo batteries while in the camera?” depends on which model you own. But here’s the kicker: none of Arlo’s official rechargeable batteries can be charged while inside the camera. You must remove them and charge them using an external charger or the Arlo charging dock.

Why Arlo Designed It This Way

You might wonder: Why doesn’t Arlo just let us charge the battery in the camera like a smartphone? It’s a fair question. The answer lies in design trade-offs:

• Weatherproofing: Arlo cameras are built for outdoor use. Sealing the battery compartment completely (to allow in-camera charging) would make the device bulkier and more expensive.
• Battery Safety: Lithium-ion batteries generate heat when charging. Charging inside a small, enclosed space like a camera could pose overheating risks, especially in direct sunlight.
• Modular Design: Removable batteries mean you can swap in a fresh one instantly. No waiting. This is a big plus for users who want 24/7 coverage.

I remember a friend who tried using a USB cable to “trick” his Arlo Pro 3 into charging the internal battery. It didn’t work—and he nearly damaged the camera’s port. Lesson learned: Arlo’s design prioritizes safety and reliability over convenience in this case.

Can You Recharge Arlo Batteries While in the Camera? The Short Answer

Here’s the straightforward answer: No, you cannot recharge Arlo batteries while they are in the camera. This applies to all models that use Arlo’s official rechargeable battery (A-2) or standard 18650/CR123A cells. The battery must be removed and charged externally.

Official Arlo Battery Charging Process

Let’s walk through the proper steps for recharging your Arlo battery:

1. Remove the camera from its mount. Use the quick-release mechanism (on Pro/Ultra models) or unscrew the housing (on Essential).
2. Open the battery compartment. On Pro/Ultra, press the latch and slide out the tray. On Essential, twist the back cover.
3. Take out the battery. Handle it carefully—avoid touching the contacts.
4. Charge using an approved method:
   • Arlo Charging Dock (recommended)
   • USB-C cable (Pro 4/Ultra 2)
   • Third-party charger (for 18650/CR123A)
5. Reinsert the battery and re-mount the camera.

This process takes about 2–3 minutes once you get used to it. I keep a spare battery charged and ready, so I can swap in a fresh one while the other charges. It’s like having a backup camera—no downtime.

What About “In-Camera” Charging Myths?

You might find forum posts or YouTube videos claiming you can charge Arlo batteries in the camera using a USB cable. Some people try plugging a USB-C cable into the camera’s port, hoping the internal battery charges. Don’t do this. Here’s why:

• The USB-C port on Arlo Pro 4/Ultra 2 is for direct power, not internal battery charging. It keeps the camera running, but it does not charge the battery while inside.
• On older models (Pro 2, Pro 3), the USB port is for firmware updates and diagnostics, not charging.
• Attempting to force charge can damage the battery, the port, or both. I’ve seen users report melted connectors and error codes after trying this.

One Reddit user shared his story: “I left my Arlo Ultra plugged in overnight, thinking it would charge the battery. Next morning, the camera was unresponsive. Had to reset it and lost a week of recordings.” Don’t make the same mistake.

Alternative Power Options: Can You Avoid Battery Swapping?

If the idea of removing and recharging batteries every few weeks sounds like a hassle, you’re not alone. The good news? Arlo offers several alternative power solutions that reduce or eliminate the need for battery swaps.

1. Arlo Solar Panels

The Arlo Solar Panel is a game-changer for outdoor cameras. It connects directly to the camera (Pro 3, Pro 4, Ultra, Essential Outdoor) and provides continuous power using sunlight.

• Pros:
  • Eliminates battery swaps (if you get enough sun)
  • Weatherproof and durable
  • Easy to install on most mounts
• Cons:
  • Not 100% reliable in cloudy areas or winter months
  • Requires direct sunlight (south-facing in the U.S.)
  • Costs extra ($30–$50 per panel)

I installed solar panels on two of my Arlo Pro 4 cameras last summer. In full sun, they’ve run for over 6 months without a single battery change. But in winter, with shorter days, I still need to swap batteries every 6–8 weeks. It’s not perfect, but it cuts maintenance in half.

2. Arlo Power Adapter (Wired Option)

For indoor or covered outdoor cameras, the Arlo Power Adapter lets you plug the camera directly into a wall outlet. It uses the same USB-C connection as the solar panel.

• Pros:
  • Zero battery swaps—ever
  • Stable power, no interruptions
  • Ideal for high-traffic areas (front door, garage)
• Cons:
  • Requires access to an outlet
  • Not suitable for fully exposed outdoor spots (rain risk)
  • Visible cable may affect aesthetics

I use the power adapter on my Arlo Essential Indoor camera. It’s mounted above the kitchen door, and since it’s always powered, I never worry about missing a delivery or a late-night visitor. The cable runs along the ceiling, so it’s barely noticeable.

3. Third-Party Battery Packs and Solar Solutions

Some users rig up external battery packs or DIY solar setups. For example, you can use a 5V USB battery bank connected to the camera’s USB port. But be cautious:

• Use only regulated 5V output to avoid overvoltage.
• Don’t leave cheap power banks in direct sunlight—they can overheat.
• DIY solar kits (like 6W USB solar panels) work, but aren’t as efficient as Arlo’s official panel.

A friend used a portable power station with his Arlo Ultra. It lasted for 3 months in a shaded backyard. But the setup was bulky and required a 10-foot cable. Not ideal for everyone.

Tips to Extend Battery Life and Reduce Recharging Frequency

Even if you can’t charge the battery in the camera, you can make it last longer. Here are practical tips I’ve tested and recommend:

1. Adjust Motion Sensitivity and Detection Zones

The biggest battery drain? Constant recording. Reduce false triggers by:

• Lowering motion sensitivity (in the Arlo app)
• Setting detection zones to ignore trees, cars, or pets
• Using “People Only” mode (on Pro 3/4, Ultra)

I lowered the sensitivity on my backyard camera after it kept recording my neighbor’s cat. Battery life jumped from 6 weeks to 10 weeks.

2. Schedule Recording Times

Use the Smart Scheduling feature to turn off the camera during low-risk hours (e.g., 9 AM–5 PM on weekdays).

• Go to Camera Settings > Recording Schedule
• Set “Always Record” to “Record Only When Armed”
• Arm the system only when you’re away or at night

This reduced my battery use by 30% on my driveway camera.

3. Optimize Video Quality

Higher video settings (1080p, 2K, 4K) use more power. If you don’t need ultra-clear footage:

• Switch to 720p (still good for most uses)
• Reduce frame rate (15 fps instead of 30 fps)
• Turn off color night vision (uses extra IR LEDs)

My front porch camera runs on 720p at 15 fps. I can still see faces and license plates clearly, and the battery lasts 3 months instead of 2.

4. Use a Spare Battery (and Label It)

Always keep a fully charged spare battery on hand. I label mine with the date of last charge using a permanent marker. That way, I rotate them and avoid overcharging.

5. Check for Firmware Updates

Arlo often releases updates that improve battery efficiency. Go to Settings > Device Info > Firmware and update regularly.

Battery Charging Best Practices: What You Need to Know

Now that we know you can’t charge Arlo batteries in the camera, let’s talk about how to charge them safely and effectively.

1. Use the Right Charger

For Arlo’s A-2 battery, the Arlo Charging Dock is the safest option. It charges two batteries at once and has overcharge protection.

• Charging time: ~2 hours
• LED indicators show charge level
• Compact and travel-friendly

For CR123A or 18650 batteries, use a smart charger (like Nitecore or Xtar). These prevent overcharging and balance cells.

2. Avoid Overcharging

Don’t leave batteries charging overnight or for days. Lithium-ion batteries degrade faster when kept at 100% for long periods. I charge mine to 80–90% for daily use and 100% only when needed.

3. Store Batteries Properly

If you’re not using a spare battery for a while:

• Store at ~50% charge
• Keep in a cool, dry place (not in a hot garage)
• Use a plastic case to avoid short circuits

4. Monitor Battery Health

Older batteries lose capacity. If your Arlo battery used to last 3 months but now only lasts 6 weeks, it’s time to replace it. Arlo batteries typically last 1–2 years with regular use.

Arlo Battery Type	Charging Method	Charging Time	Avg. Lifespan (Cycles)	Can Be Charged In-Camera?
Arlo A-2 (Pro/Ultra)	Charging Dock or USB-C	2–3 hours	500	No
CR123A (Essential)	External smart charger	4–6 hours	300 (rechargeable)	No
18650 (Wire-Free)	External charger	3–4 hours	800	No
USB Power Adapter	Wall outlet	N/A (continuous)	N/A	Yes (powers camera, not battery)

Final Thoughts: Making the Most of Your Arlo Battery Setup

So, can you recharge Arlo batteries while in the camera? The answer is a clear no—and that’s by design. While it might seem inconvenient at first, the removable battery system actually offers flexibility and safety benefits. You get to choose when to charge, use solar or wired power, and even swap batteries in seconds without losing coverage.

From my experience, the key is planning ahead. Keep a spare battery charged, use solar panels for outdoor cameras, and tweak your settings to extend battery life. These small steps make a big difference. I’ve gone from dreading battery swaps to barely noticing them—because I’ve built a system that works for my lifestyle.

Remember: Arlo’s design isn’t about making things harder. It’s about giving you control. Whether you’re a busy parent, a frequent traveler, or just someone who values peace of mind, understanding how your Arlo battery works—and how to work with it—will help you get the most out of your security system. So next time your camera blinks red, don’t stress. Grab that spare battery, pop it in, and get back to what matters most.
