Why This Matters / Understanding the Problem

You’re standing at your front door, package in hand, and your Arlo doorbell suddenly flashes a red light. Uh-oh—low battery. Again. If you’ve ever been caught off guard by a dead smart doorbell right when you need it most, you know how frustrating it can be.

Smart doorbells like Arlo are amazing—they let you see who’s at the door from anywhere, even when you’re miles away. But they run on batteries, and those batteries don’t last forever. The good news? Charging your Arlo doorbell battery isn’t rocket science. With the right steps, you can keep your doorbell running smoothly without constant replacements or unexpected outages.

Whether you’re a first-time Arlo user or just need a refresher, knowing how to charge Arlo doorbell battery properly can save you time, stress, and even money in the long run. Plus, understanding the charging process helps you get the most out of your device’s battery life.

In this guide, I’ll walk you through everything you need to know—from what tools you’ll need to step-by-step instructions, plus real-life tips I’ve learned from using my own Arlo doorbell for over two years. No jargon, no fluff—just honest, practical advice.

What You Need

Before we dive into the actual charging process, let’s make sure you have everything ready. The last thing you want is to start the process only to realize you’re missing a key item.

• Your Arlo doorbell – Obviously! Make sure it’s the battery-powered model (not the wired version).
• USB cable – Most Arlo doorbells come with a micro-USB or USB-C cable, depending on the model. Check your original packaging.
• USB power adapter – A standard phone charger or wall adapter works fine. Just make sure it’s not damaged.
• A small Phillips-head screwdriver – Needed to remove the mounting plate if your doorbell is installed.
• A clean, dry workspace – Somewhere safe to place your doorbell while it charges.

Pro tip: If you’ve misplaced your original cable, don’t panic. A high-quality third-party USB cable will work just as well—just avoid super cheap ones that might not deliver consistent power.

Step-by-Step Guide to How to Charge Arlo Doorbell Battery

Step 1: Check Your Battery Level First

Before you unplug anything, take a quick look at your Arlo app. Open it and go to your doorbell device. You’ll see a battery icon that shows the current charge level.

If it’s below 20%, it’s definitely time to charge. But even if it’s at 30%, consider charging it now—especially if you’ve noticed slower response times or missed notifications. Arlo doorbells tend to drain faster in cold weather or if you get a lot of motion alerts.

Don’t wait until it completely dies. A fully drained battery can sometimes cause the doorbell to reset or lose Wi-Fi settings, which means extra setup work later.

Step 2: Safely Remove the Doorbell from the Mount

Now it’s time to take your doorbell off the wall. If you installed it yourself, you’ll know it’s held in place by a mounting plate and a small security screw at the bottom.

Grab your Phillips-head screwdriver and gently unscrew that bottom screw. Once it’s loose, carefully slide the doorbell upward to detach it from the plate. Be gentle—there’s a small tab that locks it in place, and forcing it could damage the casing.

Once it’s off, place it on a soft surface like a towel or table mat. You don’t want to scratch the lens or drop it while handling.

Step 3: Locate the Charging Port

Flip the doorbell over. On the back, near the bottom, you’ll see a small port—either micro-USB or USB-C, depending on your model. It’s usually covered by a tiny rubber flap to protect it from weather.

Gently lift the flap and insert your USB cable. Make sure it’s fully seated. A loose connection can lead to slow charging or no charging at all.

If the port looks dusty or dirty, use a dry toothbrush or compressed air to clean it out. Moisture or debris can interfere with charging.

Step 4: Connect to Power and Start Charging

Plug the other end of the USB cable into your power adapter, then plug that into a wall outlet. Avoid using a computer USB port—it doesn’t deliver enough power for a full charge.

Once connected, the doorbell should light up. A solid white or green light usually means it’s charging. If it’s blinking, that’s normal too—it just means it’s in the process of powering up.

Now, let it charge. Most Arlo doorbells take about 2 to 4 hours to go from dead to full. I usually charge mine overnight to be safe.

Step 5: Reinstall the Doorbell

After it’s fully charged (the light will stay solid or turn off), unplug the cable and reattach the rubber flap. Then, slide the doorbell back onto the mounting plate until it clicks into place.

Finally, reinsert and tighten the security screw at the bottom. Don’t overtighten—just snug enough to keep it secure.

Open your Arlo app and check the battery level. It should now show 100% or close to it. You’re back in business!

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve learned a few tricks—and made a few mistakes—when it comes to charging my Arlo doorbell. Here’s what I wish I knew from the start.

Pro Tip: Charge your doorbell every 2–3 months, even if the battery isn’t low. This helps maintain battery health and prevents deep discharges that can shorten its lifespan.

One common mistake? Using a fast charger meant for phones. While it might seem like a good idea to charge faster, high-wattage adapters can overheat the battery. Stick to a standard 5V/1A or 5V/2A adapter.

Another thing: don’t leave your doorbell plugged in for days after it’s fully charged. Unlike phones, Arlo batteries don’t have advanced charge controllers. Overcharging can degrade the battery over time.

Also, avoid charging in extreme temperatures. If it’s freezing outside, bring the doorbell inside to charge. Cold weather slows down chemical reactions in the battery, making charging less efficient.

And here’s a personal story: I once forgot to reattach the security screw after charging. A week later, a strong wind knocked the doorbell loose, and it cracked on the pavement. Lesson learned—always double-check that screw!

FAQs About How to Charge Arlo Doorbell Battery

Q: How long does the Arlo doorbell battery last on a full charge?
A: It depends on usage, but most users get 3 to 6 months per charge. If you get lots of motion alerts or live in a cold climate, it might drain faster. Regular charging every couple of months helps maintain performance.

Q: Can I charge my Arlo doorbell while it’s still mounted?
A: Technically yes, but it’s not recommended. The cable can get tangled, and you risk damaging the port or the doorbell if someone trips over it. It’s safer and easier to remove it completely.

Q: What if my doorbell won’t charge?
A: First, check the cable and adapter—try a different one if possible. Clean the charging port. If it still won’t charge, the battery might be faulty. Contact Arlo support—they often replace batteries under warranty.

Q: Can I use a solar charger for my Arlo doorbell?
A: Not directly. Arlo doesn’t make a solar charging accessory for doorbells (yet). But you could use a portable solar power bank to charge the doorbell indoors, which is a great eco-friendly option if you’re off-grid.

Q: Does the doorbell work while charging?
A: No. Once you plug it in, the doorbell powers down and won’t send alerts or record video. That’s why it’s best to charge during low-traffic times, like overnight.

Q: How do I know if my battery needs replacing?
A: If your doorbell dies within a few weeks of a full charge, or if it won’t hold a charge at all, the battery may be worn out. Arlo batteries typically last 2–3 years with regular use.

Q: Can I charge the battery separately?
A: No, Arlo doorbells have built-in, non-removable batteries. You have to charge the entire unit. Some third-party replacement batteries claim to be removable, but I’d avoid them—they can void your warranty and cause safety issues.

Final Thoughts

Knowing how to charge Arlo doorbell battery might seem like a small thing, but it makes a big difference in how reliable your smart doorbell feels. A dead battery means missed packages, lost security alerts, and unnecessary stress.

The process is simple: check the level, remove the doorbell, charge it properly, and reinstall. With a little routine, you can keep your Arlo running smoothly for years.

My advice? Set a calendar reminder every two months to check the battery. It takes just a few minutes, but it saves you from surprises. And always use quality cables and chargers—your doorbell will thank you.

At the end of the day, your Arlo doorbell is there to give you peace of mind. Don’t let a low battery take that away. Charge it right, and it’ll keep watching your door—so you don’t have to.
