Why This Matters / Understanding the Problem

Let’s face it: no one wants to wake up to a dead security camera. I’ve been there—my Arlo camera went dark mid-week, and I realized I hadn’t checked the battery since installation. It’s easy to forget, but when your camera’s offline, so is your peace of mind.

Whether you’re setting up a brand-new Arlo camera or replacing old batteries, knowing how to insert batteries to Arlo camera in 2026 easy guide can save you from false alarms, missed motion events, or even a break-in going unnoticed. The good news? It’s not rocket science. But there are a few things you’ll want to get right the first time—especially with newer models like the Arlo Ultra 2, Arlo Pro 5, and Arlo Essential variants that have subtle differences.

From battery type to proper orientation and re-syncing after replacement, this guide walks you through every step. No tech jargon, no fluff—just real-world advice from someone who’s replaced batteries in freezing backyards and humid garages.

Real talk: I once tried to force a battery in backward (yes, really) and thought the camera was broken. Turns out, I just needed to flip it. Learn from my mistakes!

What You Need

Before we dive in, let’s gather what you’ll need. Most of this is probably already in your junk drawer or toolbox.

• Compatible batteries: Rechargeable Arlo batteries (like the Arlo CR123A or Arlo Lithium) or high-quality third-party equivalents (more on that later).
• A clean microfiber cloth: To wipe down the battery compartment and prevent dust buildup.
• A small flathead screwdriver or coin (optional): Some models have a tiny slot to help open the battery door.
• Your Arlo app (on phone/tablet): You’ll need it to check battery status and re-sync if needed.
• A dry, well-lit workspace: Especially if you’re doing this outdoors. Trust me, fumbling with tiny batteries in the dark is a recipe for frustration.
• Patience: Seriously, take your time. Rushing leads to mistakes.

Note: Not all Arlo cameras use the same battery. The how to insert batteries to Arlo camera in 2026 easy guide depends on your specific model. We’ll cover the most common ones: Arlo Pro 3/4/5, Arlo Ultra, Arlo Essential, and Arlo Go 2.

Step-by-Step Guide to How to Insert Batteries to Arlo Camera in 2026 Easy Guide

Step 1: Identify Your Arlo Camera Model

First things first: not all Arlo cameras use the same battery setup. The Arlo Pro 5S uses a proprietary rechargeable pack, while the Arlo Essential uses standard CR123A lithium batteries.

Check the back or bottom of your camera for the model number. Or, open the Arlo app, tap your camera, and go to Device Settings > About Device. This will tell you exactly what battery type you need.

• Arlo Pro 3/4/5, Ultra, Ultra 2: Use the Arlo rechargeable battery pack (model: Arlo CR123A or Arlo Lithium).
• Arlo Essential (wired or battery): Uses two CR123A lithium batteries (non-rechargeable or rechargeable).
• Arlo Go 2: Uses a built-in rechargeable battery (no user-replaceable cells).

Pro tip: If you’re unsure, take a photo of the battery compartment and send it to Arlo support. They’ll confirm the right battery in minutes.

Step 2: Power Down the Camera (If Possible)

While most Arlo cameras are designed to be hot-swapped (meaning you can change batteries while the camera is “on”), it’s safer to power down first. This avoids any glitches or sync issues.

In the Arlo app:

1. Tap your camera.
2. Go to Device Settings > Power Management.
3. Select Sleep or Turn Off (available on newer models).

For older models without a sleep mode, you can skip this step. The camera will simply go offline temporarily—no harm done.

Step 3: Locate and Open the Battery Compartment

This is where things get model-specific. Here’s how to open the battery door on the most common Arlo cameras:

• Arlo Pro 3/4/5, Ultra, Ultra 2: Flip the camera over. You’ll see a small, circular door on the bottom. Use your fingernail or a coin to gently twist the latch counterclockwise. The door will pop open.
• Arlo Essential: The battery compartment is on the back. Slide the cover upward (toward the lens). It’s spring-loaded, so it’ll click open.
• Arlo Go 2: No user-accessible battery. Skip to charging via USB-C.

Take a moment to inspect the compartment. Look for dust, corrosion, or moisture. Wipe it gently with a dry microfiber cloth. Moisture is a silent killer for lithium batteries.

Warning: Don’t use water or cleaning sprays. Just a dry cloth. I learned this after a friend used a damp wipe and shorted their camera.

Step 4: Remove Old Batteries (If Replacing)

If you’re replacing batteries, carefully pull them out. For Arlo Pro/Ultra models with a battery pack, gently lift the pack out by the edges.

For Arlo Essential (two CR123A batteries), note the orientation. There are small + and – symbols molded into the plastic. Take a photo with your phone before removing them—this helps you remember the correct way to insert the new ones.

• Never force batteries out. If stuck, wiggle them slightly.
• Dispose of old batteries properly. Many electronics stores offer free battery recycling.

Pro tip: If your batteries are swollen or leaking, stop. Don’t touch them with bare hands. Use gloves and place them in a sealed container. Contact your local hazardous waste facility.

Step 5: Insert the New Batteries

Now for the main event: inserting the new batteries. This is where the how to insert batteries to Arlo camera in 2026 easy guide really shines.

For Arlo Pro/Ultra (Battery Pack Models):

1. Align the battery pack with the slot. The Arlo logo should face outward.
2. Slide it in gently until it clicks into place.
3. Close the battery door and twist the latch clockwise to lock it.

You’ll hear a soft click when it’s secure. If it doesn’t click, it’s not seated properly—don’t force it.

For Arlo Essential (CR123A Batteries):

1. Insert the first battery with the + side facing up (toward the lens).
2. Insert the second battery with the + side facing down (toward the base).
3. Slide the battery cover back into place and push it down until it clicks.

Common mistake: I once put both batteries with the + side up. The camera wouldn’t power on. Took me 20 minutes to figure out. Orientation matters!

Step 6: Reattach and Re-Sync the Camera

Once the batteries are in, reattach the camera to its mount. Make sure it’s secure and pointed in the right direction.

Now, turn the camera back on:

• Arlo Pro/Ultra: The camera should power on automatically. If not, press and hold the sync button (on the back) for 3 seconds.
• Arlo Essential: It should power on within 10 seconds. If not, press the sync button on the back.

Open the Arlo app. You’ll see a notification: “Camera is offline.” Don’t panic. Tap your camera, then tap Sync. The app will search for the camera. It usually reconnects within 30 seconds.

If it doesn’t connect:

• Check that the battery door is fully closed.
• Ensure the camera is within 300 feet of your base station or Wi-Fi.
• Restart the camera by holding the sync button for 10 seconds.

Step 7: Check Battery Status and Test

Once synced, go to the Arlo app and check the battery level:

• Tap your camera.
• Look under Device Health or Battery.

For rechargeable packs, you’ll see a percentage (e.g., 95%). For CR123A batteries, you’ll see “Battery Level: High/Medium/Low.”

Test the camera:

• Wave your hand in front of the lens. The motion light should flash.
• Check the live feed in the app.
• Verify that notifications are working (if enabled).

Pro tip: Set a monthly reminder in your phone to check battery levels. I use Google Calendar with a recurring event: “Check Arlo Batteries.”

Pro Tips & Common Mistakes to Avoid

Over the years, I’ve picked up a few tricks (and made a few blunders). Here’s what I wish I knew earlier:

• Use genuine Arlo batteries when possible. Third-party CR123A batteries can work, but some don’t last as long or trigger low-battery alerts too early. I tried a cheap brand once—lasted 2 weeks. Genuine Arlo packs last 3–6 months.
• Store spare batteries properly. Keep them in a cool, dry place (not the garage in summer). Extreme heat or cold reduces lifespan.
• Don’t mix old and new batteries. If you’re using two CR123As, replace both at the same time. Mixing ages can cause uneven power draw.
• Label your batteries. If you have multiple cameras, label spare batteries with the model and install date. I use a Sharpie on the plastic wrap.
• Check the O-ring seal. On outdoor cameras, the battery door has a rubber O-ring. If it’s cracked or missing, moisture can get in. Replace it if damaged.
• Don’t overtighten the battery door. Just snug it. Over-tightening can crack the plastic.

Real story: My neighbor’s Arlo camera died after a storm. Turns out, water got in through a loose battery door. Now I always double-check the seal after battery changes.

FAQs About How to Insert Batteries to Arlo Camera in 2026 Easy Guide

Q: Can I use rechargeable CR123A batteries in my Arlo Essential?

Yes, but with a caveat. Some rechargeable CR123As have lower voltage (3.0V vs. 3.6V for lithium). This can cause the camera to report low battery even when the cells are full. Stick with lithium rechargeable CR123As (like Tenergy or EBL) for best results.

Q: Why won’t my Arlo camera sync after battery replacement?

It’s usually one of three things: the battery door isn’t fully closed, the camera is too far from the base station, or the sync button wasn’t pressed. Try this: close the door, move the camera closer to your router or base station, and hold the sync button for 10 seconds.

Q: How long do Arlo batteries last?

It depends on usage. With moderate motion (10–15 events per day), a genuine Arlo battery pack lasts 3–6 months. CR123A batteries last 2–4 months. In cold climates, battery life drops by up to 30%. I’ve seen mine die faster in winter.

Q: Can I charge Arlo batteries with a third-party charger?

Only if the charger is compatible with Arlo battery packs. The Arlo Pro/Ultra battery packs use a proprietary connector. Third-party chargers may not fit or could damage the pack. Stick with the Arlo charging dock or use the USB cable that came with your camera.

Q: What if my Arlo camera doesn’t power on after battery insertion?

First, double-check orientation. Then, ensure the battery pack is fully seated. If it still doesn’t work, try a different battery. If the camera powers on with a new battery, the old one was likely dead. If not, contact Arlo support—your camera might have a hardware issue.

Q: Is it safe to change batteries in the rain?

Not really. Water and electronics don’t mix. If you must, use a plastic bag or umbrella to shield the camera. Dry the battery compartment thoroughly before closing. Better yet, wait for a dry day.

Q: Can I use AA batteries in my Arlo camera?

No. Arlo cameras use CR123A or proprietary packs. AA batteries are the wrong size and voltage. Don’t try to rig an adapter—it won’t work and could damage the camera.

Final Thoughts

Changing batteries in your Arlo camera isn’t glamorous, but it’s essential. A dead battery means a blind spot in your security system. With this how to insert batteries to Arlo camera in 2026 easy guide, you now have everything you need to do it right—every time.

Remember: take your time, check orientation, keep the battery compartment clean, and test the camera after reinsertion. A few minutes now can prevent hours of frustration later.

And hey, if you’re like me and tend to forget, set a reminder. I check mine every 6 weeks—even if the battery shows “high.” Prevention beats panic.

Your home’s safety shouldn’t depend on a forgotten battery. So go ahead—swap those cells, re-sync, and rest easy knowing your Arlo is back on duty.

Stay safe, stay charged.
