Let’s get started and keep your front door smart and secure.

Understanding Your Aqara Doorbell Camera Model

Before diving into the battery replacement process, it’s crucial to identify your specific Aqara Doorbell Camera model. Aqara has released several versions over the years, including the Aqara Video Doorbell G2H, G3, Doorbell Camera Hub G2H Pro, and the newer Aqara Doorbell Camera 2. While the core principles of battery replacement are similar across models, slight differences exist in design, battery compartment access, and battery type. Using the wrong battery or forcing a component can lead to malfunctions or void your warranty.

Identifying Your Model

The easiest way to confirm your model is to check the back of the doorbell unit. Most Aqara doorbells have a label printed on the rear panel that includes the model number, serial number, and regulatory information. For example:

• Aqara Doorbell G2H: Model number DBL11
• Aqara Doorbell G3: Model number DBL13
• Aqara Doorbell Camera 2: Model number DBL21

Alternatively, you can open the Aqara Home app, navigate to the device settings, and look for the “Device Information” section. This will display the model, firmware version, and battery level. Knowing your model helps you purchase the correct replacement battery and follow the right instructions.

Why Battery Type Matters

Aqara doorbell cameras typically use lithium-ion (Li-ion) batteries due to their high energy density, long cycle life, and stable performance in outdoor conditions. However, the exact specifications (voltage, capacity, and form factor) vary by model:

• G2H: Uses a built-in 4800mAh Li-ion battery (non-removable, requires charging via micro-USB)
• G3: Features a removable 6000mAh Li-ion battery pack (model: BL-6000)
• Doorbell Camera 2: Uses a 5200mAh removable battery (model: BL-5200)

Using a third-party or incompatible battery can result in poor performance, overheating, or even damage to the device. Always opt for Aqara-certified or manufacturer-recommended replacements. For example, the G3’s BL-6000 battery is widely available on Amazon, AliExpress, or through Aqara’s official website.

Preparing for the Battery Change

Replacing the battery in your Aqara doorbell camera is a straightforward process, but preparation is key to avoid frustration or mistakes. A little planning ensures a smooth, safe, and efficient battery swap. Here’s what you need to do before removing the doorbell.

Gather the Right Tools and Supplies

You don’t need a full toolbox, but having a few essentials makes the job easier:

• Replacement battery (model-specific, as discussed above)
• Small Phillips-head screwdriver (typically #0 or #1 size)
• Plastic pry tool or credit card (to avoid scratching the doorbell housing)
• Clean microfiber cloth (to wipe down the unit and remove dust)
• Smartphone or tablet (to monitor the Aqara app during the process)
• Charging cable and power source (for models that require pre-charging the battery)

For example, if you’re replacing the battery in a G3, make sure the new BL-6000 battery is fully charged before installation. The Aqara app will notify you when the battery is low (usually below 20%), but don’t wait until it’s completely dead — this can cause temporary disconnection from the hub or Wi-Fi network.

Check the Aqara App and Notify Household Members

Before starting, open the Aqara Home app and check the following:

• Current battery level
• Firmware version (update if needed)
• Connection status (Wi-Fi, Zigbee, or Hub)

It’s also a good idea to notify family members or housemates that the doorbell will be offline during the replacement. This prevents confusion if someone rings the doorbell and no one responds. For added convenience, you can temporarily enable a secondary alert method, such as a smart speaker announcement or a phone call through IFTTT or Home Assistant.

Work in a Safe and Dry Environment

Since you’ll be handling electrical components, avoid working in wet or rainy conditions. If your doorbell is exposed to the elements, wait for a dry day or work under an overhang. Remove any water or condensation from the doorbell surface before opening the battery compartment. Also, ensure your hands are dry to prevent static discharge, which can damage sensitive electronics.

Step-by-Step Battery Replacement Process

Now that you’re prepared, let’s walk through the actual battery replacement process. We’ll focus on the most common models — the Aqara Doorbell G3 and Doorbell Camera 2 — as they use removable batteries. The G2H, which has a built-in battery, requires a different approach (covered in a later section).

Step 1: Power Down and Disconnect

Although Aqara doorbells are designed to handle brief disconnections, it’s best to power down the device to prevent any glitches. In the Aqara Home app, go to the doorbell settings and tap “Turn Off” or “Pause Device.” This stops video recording and disables motion detection temporarily.

Next, if your doorbell is wired to a chime or power adapter (some models support dual power), unplug it. For battery-only models, simply proceed to the next step.

Step 2: Remove the Doorbell from the Mount

Most Aqara doorbells are secured to a mounting bracket with one or two screws. Use your Phillips screwdriver to remove the bottom screw (and the top screw, if present). Some models, like the G3, have a quick-release mechanism:

1. Insert the plastic pry tool into the small gap at the bottom of the doorbell.
2. Gently wiggle it upward to release the latch.
3. Slide the doorbell up and off the bracket.

Tip: Place a soft cloth under the doorbell as you remove it to prevent scratching the finish or damaging the lens.

Step 3: Open the Battery Compartment

On the G3 and Doorbell Camera 2, the battery compartment is located on the back of the unit. Use the screwdriver to remove the single screw securing the battery cover. Then, carefully lift the cover — it may have a rubber gasket for weatherproofing, so don’t force it.

Inside, you’ll see the battery pack connected to the main board via a small connector. Gently unplug the battery by pressing the release tab (usually a small plastic lever) and pulling the connector straight out. Avoid yanking on the wires.

Step 4: Install the New Battery

Insert the new battery into the compartment, making sure it sits flat and aligns with the connector. Push the connector into place until you hear a soft click — this indicates a secure connection. Replace the battery cover and tighten the screw firmly, but don’t over-tighten, as this can crack the plastic.

Pro Tip: Before reattaching the doorbell, power it on briefly by pressing the button on the side. The LED should flash blue or green, indicating the battery is recognized. If it doesn’t light up, double-check the connection.

Step 5: Reattach the Doorbell

Slide the doorbell back onto the mounting bracket, ensuring it clicks into place. Reinsert the screws and tighten them securely. For wired models, reconnect the power adapter or chime cable. Wipe down the lens and housing with a microfiber cloth to remove fingerprints or smudges.

Step 6: Reconnect and Test

Open the Aqara Home app and check the battery level — it should now show 100% (or the current charge level). Tap the live view to ensure the camera is streaming. Test the motion detection and doorbell ring by pressing the button or walking in front of the lens. Confirm that notifications are working on your phone.

Special Case: Charging Built-in Batteries (G2H)

Not all Aqara doorbells use removable batteries. The Aqara Doorbell G2H has a built-in 4800mAh Li-ion battery that cannot be replaced without opening the unit — a process not recommended for most users due to warranty and water resistance concerns. Instead, the G2H is designed to be charged in place or removed for charging.

Charging the G2H In Place

If your G2H supports wired power (via a 12-24V AC/DC transformer or a USB power adapter), you can keep it mounted while charging:

1. Connect the included micro-USB cable to the charging port (located on the side or back).
2. Plug the other end into a wall charger or USB port.
3. The LED will pulse red during charging and turn solid green when full (about 6-8 hours).

Note: Charging in place is ideal for cold climates, as removing the doorbell in freezing temperatures can damage the housing or internal components.

Removing the G2H for Charging

If you prefer to remove the unit for charging, follow these steps:

1. Remove the mounting screws and gently slide the doorbell off the bracket.
2. Use the plastic pry tool to open the rear cover (held by adhesive and clips).
3. Disconnect the battery connector (optional, but recommended to avoid strain on the cable).
4. Charge the unit using a micro-USB cable.
5. Reconnect the battery, reseal the cover with silicone (to maintain IP55 rating), and reattach the doorbell.

Warning: Opening the G2H voids the warranty and risks water ingress. Only attempt this if you’re comfortable with DIY electronics and use proper sealing techniques.

Maintenance Tips and Battery Longevity

Changing the battery is just one part of maintaining your Aqara doorbell camera. To maximize battery life, ensure reliable performance, and avoid frequent replacements, follow these best practices.

Optimize Battery Usage

Smart doorbells consume power based on usage patterns. To extend battery life:

• Adjust motion detection sensitivity in the app to reduce false triggers.
• Lower video resolution from 1080p to 720p if high detail isn’t essential.
• Limit live view sessions — each minute of streaming uses significant power.
• Enable “Low Battery Mode” (if available), which reduces recording frequency.

For example, a G3 with moderate use (10-15 rings per day) typically lasts 3-4 months on a full charge. In cold climates, this drops to 2-3 months due to reduced battery efficiency.

Store and Charge Batteries Properly

Lithium-ion batteries degrade over time, especially when stored improperly. Follow these guidelines:

• Store spare batteries at 40-60% charge in a cool, dry place (15-25°C).
• Fully charge before first use and every 6 months if unused.
• Avoid deep discharges — recharge at 20-30% rather than waiting for 0%.

Monitor Firmware and Settings

Firmware updates often include battery optimization improvements. Regularly check for updates in the Aqara app. Also, ensure your doorbell is connected to a stable Wi-Fi or Zigbee network — a weak signal forces the device to work harder, draining the battery faster.
