Why Proper Battery Installation Matters

The Aqara Doorbell is a sleek, wireless smart doorbell that relies entirely on battery power. Unlike wired models, it doesn’t connect to your home’s electrical system, so battery life is crucial. Installing the wrong batteries, inserting them incorrectly, or failing to secure the cover can lead to poor performance, frequent disconnections, or even permanent damage.

Using the correct CR123A lithium batteries ensures optimal voltage and longevity. These batteries are designed for high-drain devices like smart doorbells and security cameras. They also perform well in extreme temperatures, which is important if your doorbell is exposed to outdoor conditions.

Additionally, proper installation prevents moisture from entering the device. The Aqara Doorbell is weather-resistant, but only if the back cover is sealed tightly after battery replacement. A loose cover can allow water or dust to seep in, leading to corrosion or malfunction.

What You’ll Need Before Starting

Before you begin, gather the following items to make the process smooth and safe:

• Two CR123A lithium batteries: Always use new, high-quality batteries from a reputable brand. Avoid cheap or rechargeable CR123A batteries unless specifically labeled as compatible.
• A clean, dry workspace: Choose a flat surface with good lighting. Avoid working outdoors in wet or windy conditions.
• A small Phillips-head screwdriver (optional): Some Aqara Doorbell models have a small screw securing the back cover. Check your model to see if this is required.
• Soft cloth or microfiber towel: Use this to wipe the battery compartment and contacts if needed.
• Smartphone with Aqara Home app installed: You’ll need this to power down the device and check battery status afterward.

Having everything ready beforehand saves time and reduces the risk of dropping small parts or batteries.

Step 1: Power Down the Aqara Doorbell

Before removing the back cover or touching any internal components, it’s essential to power down the doorbell through the Aqara Home app. This prevents accidental triggers, false motion alerts, or damage to the internal circuitry.

Open the Aqara Home App

Launch the Aqara Home app on your smartphone. Make sure you’re logged into the correct account and that your doorbell is connected to your home network.

Locate Your Doorbell Device

Navigate to the “Devices” tab and find your Aqara Doorbell in the list. Tap on it to open the device control panel.

Turn Off the Device

Look for a power or settings icon (usually a gear or toggle switch). Tap it and select “Power Off” or “Disable Device.” Wait for the confirmation message that the doorbell is offline.

Tip: If you can’t find the power-off option, check under “Device Settings” or “Advanced Settings.” Some models require you to disable motion detection and notifications first.

Powering down ensures the device isn’t actively recording or transmitting data while you’re handling it. This is especially important if you’re replacing batteries due to low power—don’t assume the device is already off.

Step 2: Remove the Back Cover

Once the doorbell is powered off, you can safely remove the back cover to access the battery compartment.

Locate the Release Mechanism

Most Aqara Doorbell models have a snap-on back cover. Look for a small indentation or groove along the bottom edge of the device. This is where you’ll apply pressure to release the cover.

Gently Pry Open the Cover

Insert your fingernail or a plastic prying tool into the groove and gently lift upward. Avoid using metal tools like screwdrivers, as they can scratch or crack the plastic.

If your model has a small screw (common in older versions), use a Phillips-head screwdriver to remove it first. Keep the screw in a safe place—you’ll need it to reattach the cover later.

Remove the Cover Completely

Once the clips release, carefully lift the cover away from the doorbell. Set it aside on a clean surface to avoid losing it or damaging the internal components.

Caution: Do not force the cover open. If it doesn’t budge, double-check for hidden screws or clips. Forcing it can break the plastic or damage the battery contacts.

Step 3: Remove Old Batteries (If Applicable)

If you’re replacing old batteries, now is the time to remove them safely.

Identify the Battery Orientation

Look inside the battery compartment. You’ll see two slots with small metal contacts at each end. Note the direction of the old batteries—there are usually small “+” and “–” symbols molded into the plastic.

Remove the Batteries

Gently push the batteries toward the open end of the compartment and lift them out. Use your fingers or a non-conductive tool like a plastic spudger.

Tip: If the batteries are stuck, tilt the doorbell slightly to let them slide out. Never use metal tools to pry them—this can short-circuit the batteries or damage the contacts.

Dispose of Old Batteries Properly

CR123A batteries contain lithium and should not be thrown in regular trash. Take them to a local battery recycling center or a store that accepts hazardous waste (many electronics retailers offer this service).

Store the old batteries in a non-conductive container (like a plastic bag) until you can recycle them safely.

Step 4: Insert New Batteries

Now it’s time to install the new CR123A batteries. This step is critical—incorrect installation can prevent the doorbell from working.

Check Battery Polarity

Each battery has a positive (+) end (the protruding tip) and a negative (–) end (the flat side). The battery compartment will have corresponding symbols. Match the “+” on the battery with the “+” in the slot.

Example: In most Aqara Doorbell models, the positive ends face outward (away from the center of the device).

Insert the First Battery

Slide the first battery into its slot, positive end first. Press it gently until it sits flush against the contact. You should feel a slight click or resistance when it’s properly seated.

Insert the Second Battery

Repeat the process for the second battery, ensuring it’s oriented correctly. Both batteries should be snug and level.

Tip: If the batteries don’t fit easily, double-check the orientation. Forcing them can bend the contacts or crack the casing.

Verify Installation

Look inside the compartment to confirm both batteries are properly aligned and seated. The metal contacts should be touching the battery ends without any gaps.

Step 5: Reattach the Back Cover

With the new batteries in place, it’s time to secure the back cover.

Align the Cover

Hold the cover so the clips line up with the slots on the doorbell body. Make sure the screw hole (if present) matches the mounting point.

Snap the Cover into Place

Press the cover firmly along the edges until you hear or feel the clips engage. Start from the top and work your way down to ensure even pressure.

If your model has a screw, reinsert it and tighten it gently with a screwdriver. Do not overtighten—this can strip the screw or crack the plastic.

Check for Gaps

Run your finger around the edge of the cover to ensure it’s flush with the doorbell body. Any gaps could allow moisture to enter.

Tip: If the cover feels loose, remove it and reinsert the batteries. Sometimes a misaligned battery can prevent the cover from sealing properly.

Step 6: Power On and Test the Doorbell

Now that the batteries are installed and the cover is secure, it’s time to power up the device and verify everything is working.

Open the Aqara Home App

Return to the Aqara Home app and navigate to your doorbell device.

Turn the Device Back On

Tap the power or settings icon and select “Power On” or “Enable Device.” Wait a few seconds for the doorbell to reconnect to your Wi-Fi network.

Check Battery Status

Once online, the app should display the current battery level. A full charge typically shows 100% or “Full.” If it shows a low percentage, double-check the battery installation.

Test the Doorbell

Press the doorbell button to trigger a notification on your phone. You should hear a chime (if connected to a chime unit) and receive a live video feed.

Tip: If the doorbell doesn’t respond, wait 30–60 seconds for it to fully boot up. Some models take a moment to initialize after a power cycle.

Troubleshooting Common Issues

Even with careful installation, you might encounter problems. Here’s how to fix the most common issues:
