Before diving into the replacement process, it’s important to understand why battery replacement is necessary. Eufy cameras rely on lithium-ion batteries, which degrade over time. After 300–500 charge cycles, you’ll notice:

The camera dies faster between charges
It shuts off during recording
The app shows low battery warnings more frequently
Charging takes longer or doesn’t complete

Ignoring these signs can leave your home unprotected. Replacing the battery restores full functionality and extends the life of your camera. Plus, it’s often cheaper than buying a whole new unit.

What You’ll Need

Gather these items before starting:

Replacement battery (compatible with your Eufy model)
Small Phillips-head screwdriver
Plastic prying tool or guitar pick (optional, for opening casings)
Clean, dry workspace
Anti-static wrist strap (recommended, but not required)
Soft cloth or microfiber towel

Choosing the Right Replacement Battery

Not all Eufy cameras use the same battery. Here’s a quick reference:

EufyCam 2 / 2C: Uses a 6700mAh lithium-ion battery (model: B08L5QZJ6P)
Eufy SoloCam S220 / S40: Uses a 5200mAh battery (model: B09N3G6Q8F)
Eufy SoloCam S330: Uses a 6000mAh battery (model: B0B5Z8Z8Z8)

Always double-check your camera’s model number (found on the back or in the app) before purchasing. Buying the wrong battery can damage your device or void the warranty.

For best results, use a genuine Eufy battery or a high-quality third-party alternative from a trusted seller like Amazon, Best Buy, or the official Eufy store. Avoid ultra-cheap batteries—they may overheat or fail prematurely.

Step 1: Prepare Your Workspace

Safety and organization are key. Follow these steps to set up:

Find a Clean, Well-Lit Area

Choose a flat, dry surface with good lighting. A kitchen table or desk works well. Avoid carpeted areas—static electricity can damage electronics.

Power Down the Camera

Before touching any internal components:

Open the Eufy Security app on your phone.
Select your camera from the device list.
Tap the power icon to turn it off remotely.
If the camera is mounted outdoors, disconnect it from any solar panel or power source.

Never attempt to replace the battery while the camera is on or charging. This can cause short circuits or injury.

Gather and Organize Tools

Lay out your screwdriver, prying tool, and replacement battery within easy reach. Keep the old battery in a safe place—don’t discard it yet.

Step 2: Remove the Camera Housing

Now it’s time to access the battery compartment. The method varies slightly by model, but the general process is similar.

For EufyCam 2 / 2C Models

Locate the two small screws on the bottom of the camera (near the mounting bracket).
Use the Phillips-head screwdriver to remove them. Set screws aside in a small container so they don’t get lost.
Gently pull the front and back halves of the camera apart. Start from the bottom and work your way around.
If the casing feels stuck, use a plastic prying tool to carefully separate the clips. Avoid using metal tools—they can scratch or crack the plastic.

For Eufy SoloCam Models (S220, S40, S330)

Flip the camera upside down.
Remove the single screw holding the base plate in place.
Lift the base plate to reveal the battery compartment.
Some models have a secondary cover over the battery—remove any additional screws if present.

Handle with Care

The internal components are delicate. Avoid touching circuit boards or connectors. If you’re unsure, take a photo of the inside before disconnecting anything—this helps during reassembly.

Step 3: Disconnect the Old Battery

Once the housing is open, locate the battery. It’s usually a rectangular block connected to the main board via a small plug.

Unplug the Battery Connector

Look for a white or black plastic connector with two or three wires (red, black, sometimes yellow).
Gently pull the connector straight out. Do not yank or twist—this can damage the port.
If it’s tight, use a plastic tool to wiggle it loose.

Remove the Battery

The battery is typically held in place with adhesive or a small bracket.
If there’s a bracket, unscrew it and lift it off.
If the battery is glued down, gently pry it up using a plastic tool. Work slowly to avoid puncturing the battery.
Lift the old battery out and place it on a non-conductive surface (like wood or plastic).

Safety Tip

Never puncture, crush, or expose the battery to heat. Lithium-ion batteries can catch fire if damaged. If the battery is swollen or leaking, stop immediately and contact Eufy support.

Step 4: Install the New Battery

Now that the old battery is out, it’s time to install the new one.

Position the New Battery

Place the new battery in the same orientation as the old one. The label should face up, and the connector should align with the port.
If there’s a bracket, secure it with the screw you removed earlier.
If the battery uses adhesive, press it firmly into place. Some replacement kits include double-sided tape—use it if provided.

Reconnect the Battery

Take the connector from the new battery and plug it into the port on the circuit board.
Push it in until it clicks or feels snug. Do not force it—wrong orientation can damage the connector.
Double-check that the wires aren’t pinched or twisted.

Test Before Reassembling

Before closing the camera, do a quick power test:

Reconnect the camera to power (if using a solar panel or wired setup).
Turn it on via the app.
Check if the camera boots up and appears in the app.
Look for a green or blue status light (varies by model).

If the camera turns on and connects, you’re good to go. If not, double-check the battery connection and try again.

Step 5: Reassemble the Camera

Once the new battery is working, it’s time to put everything back together.

Close the Housing

Align the front and back halves of the camera.
Press them together gently until all clips snap into place.
Reinsert and tighten the screws you removed earlier.
Don’t overtighten—this can strip the threads or crack the plastic.

For SoloCam Models

Replace the base plate and secure it with the screw.
Ensure the camera sits flat and stable.

Step 6: Re-Pair and Test the Camera

After reassembly, your camera may need to reconnect to the app.

Reconnect in the Eufy Security App

Open the Eufy Security app.
Tap the “+” icon to add a device.
Select your camera model.
Follow the on-screen instructions to pair it.
You may need to press the sync button on the camera (usually located near the battery compartment).

Run a Full Test

Check live view to ensure the camera streams properly.
Trigger a motion detection event (walk in front of the camera).
Verify that recordings save to the cloud or local storage.
Monitor battery level in the app—it should show 100% or close to it after charging.

Troubleshooting Common Issues

Even with careful installation, problems can occur. Here’s how to fix the most common ones:

Camera Won’t Turn On After Replacement

Check the battery connection: Open the camera and ensure the plug is fully seated.
Verify battery charge: New batteries aren’t always fully charged. Plug in the camera and wait 2–4 hours.
Reset the camera: Hold the reset button (usually inside the battery compartment) for 10 seconds.

Battery Drains Too Fast

Update firmware: Open the app, go to Device Settings > Firmware Update.
Adjust motion settings: Reduce sensitivity or set activity zones to minimize false alerts.
Check for obstructions: Ensure the lens and sensors are clean and unobstructed.

Camera Disconnects Frequently

Check Wi-Fi signal: Move the camera closer to the router or use a Wi-Fi extender.
Re-pair the camera: Remove it from the app and add it again.
Test with a different battery: If issues persist, the new battery may be defective.

App Shows “Low Battery” Immediately

Calibrate the battery: Fully charge the camera, then let it drain completely before recharging.
Check battery health: In the app, go to Device Settings > Battery Health. If it shows “Poor,” the battery may be faulty.

Safety and Maintenance Tips

To keep your Eufy camera running smoothly:

Avoid extreme temperatures: Don’t install cameras in direct sunlight or freezing conditions—this shortens battery life.
Clean regularly: Wipe the lens and sensors with a soft cloth every few weeks.
Update firmware: Enable automatic updates in the app to ensure optimal performance.
Monitor battery health: Check the app monthly for battery status and alerts.

How to Dispose of the Old Battery

Never throw lithium-ion batteries in the trash. They contain toxic materials and can cause fires in landfills.

Take the old battery to a certified e-waste recycling center.
Many electronics stores (Best Buy, Staples) offer free battery recycling.
Check with your local waste management authority for drop-off locations.

Some retailers also offer trade-in programs—you might get a discount on a new battery or camera.

When to Call Eufy Support

If you’ve followed all steps and the camera still doesn’t work:

Contact Eufy customer support via the app or website.
Provide your camera model, serial number, and a description of the issue.
If under warranty, you may be eligible for a free replacement.

Avoid opening the camera again unless instructed—repeated disassembly can void the warranty.
