1. Understanding Your Aqara Doorbell Model and Battery Type

Identifying Your Specific Aqara Doorbell Model

Before you begin, it’s essential to identify your exact Aqara doorbell model. Aqara offers several variants, each with slightly different battery specifications and replacement processes. The most common models include:

• Aqara Video Doorbell G2H (Wired & Battery): Features a rechargeable 6500mAh lithium-ion battery and supports both wired and wireless operation.
• Aqara Wireless Doorbell H1: Uses two CR2450 coin-cell batteries, ideal for quick replacements.
• Aqara Doorbell Camera (D100): Houses a built-in 5200mAh battery, requiring disassembly for replacement.

To confirm your model, check the device label (usually on the back or bottom), the original packaging, or the Aqara Home app. For example, if your doorbell displays “G2H” in the app under “Device Info,” you’re working with the 6500mAh model. Misidentifying your model can lead to purchasing the wrong battery or using improper tools.

Battery Specifications and Replacement Options

Each model uses a different battery type, and using the wrong one can damage your device or void the warranty. Here’s a breakdown:

Safety and Workspace Setup

Safety is paramount. Follow these steps to create a risk-free environment:

1. Power Down: Disconnect the doorbell from any wired power source (for G2H wired models). Turn off the circuit breaker if hardwired.
2. Work Indoors: Perform the battery change in a dry, well-lit area (e.g., a table). Avoid outdoor work—rain or humidity can damage components.
3. Ground Yourself: Touch a metal object (e.g., a faucet) to discharge static electricity before handling the device.
4. Protect the Surface: Place a soft cloth under the doorbell to prevent scratches.

Practical Example: When replacing the G2H battery, a user in Seattle accidentally cracked the casing by using a metal screwdriver as a pry tool. Switching to a plastic pry tool (included in many repair kits) saved the device from permanent damage.

3. Step-by-Step Battery Replacement Process

Step 1: Remove the Doorbell from Its Mount

For G2H:

1. Locate the mounting bracket screws (usually two at the top).
2. Use the Phillips #00 screwdriver to remove them.
3. Gently slide the doorbell upward to detach it from the bracket.

For H1:

1. Press the release tab on the bottom of the doorbell.
2. Pull the device away from the wall mount.

For D100:

1. Remove the Torx T6 screws on the backplate.
2. Use the spudger to gently pry the housing apart (start at the corners).

Pro Tip: Take a photo of the mounting setup before disassembly. This helps you reattach the doorbell correctly later.

Step 2: Access the Battery Compartment

G2H: Flip the doorbell over. The battery compartment is secured with a plastic latch. Insert the pry tool into the slot (marked by a small arrow) and gently lift. The cover will pop off.

H1: Locate the battery compartment on the back. Insert the flathead screwdriver into the slot and twist to open. The cover will hinge open, revealing two CR2450 slots.

D100: After removing the backplate, locate the battery pack (a black rectangle with a white connector). Disconnect the battery cable by pulling the connector straight out (do not yank the wires).

Step 3: Remove the Old Battery

G2H: The battery pack is held in place with adhesive. Use the pry tool to lift one corner, then slide it under the pack to release the adhesive. Avoid bending the battery—lithium-ion packs can leak if damaged.

H1: Use the screwdriver to gently lift the old CR2450 batteries. Note their orientation (positive side up).

D100: Unscrew the battery pack’s retaining bracket (if present). Carefully lift the pack, ensuring no wires are caught.

Step 4: Install the New Battery

G2H: Place the new battery pack into the compartment, adhesive-side down. Press firmly to secure it. Reconnect the cable by pushing the connector in until it clicks.

H1: Insert the new CR2450 batteries with the positive side up. Ensure they sit flush in the slots.

D100: Position the new battery pack, reconnect the cable, and secure the bracket. Double-check the connection—a loose cable can cause power failures.

Step 5: Reassemble and Test

All Models:

1. Replace the battery compartment cover (G2H/H1) or backplate (D100).
2. Reattach the doorbell to the mount.
3. Open the Aqara Home app and verify the device is online.
4. Press the doorbell button to test audio and video (if applicable).

• Temperature: Charge in a cool, dry place (15°C-25°C / 59°F-77°F). Extreme heat degrades batteries.

Storage and Replacement Timing

When to Replace:

• G2H: Every 12-18 months (or when runtime drops below 2 weeks).
• H1: Every 6-9 months (CR2450s drain faster in cold climates).
• D100: Every 2 years (or if the device overheats).

Storage Tips:

• Store spare batteries at 50% charge in a cool, dry place.
• For the H1, remove CR2450s if storing the doorbell for >3 months to prevent leakage.

Environmental Impact and Disposal

Recycle Responsibly:

• Lithium-ion Batteries (G2H/D100): Take to an e-waste facility. Never dispose in regular trash.
• Coin-Cell Batteries (H1): Recycle via battery drop-off programs (e.g., Call2Recycle).

Data Table: Battery Lifespan and Disposal Guidelines

Model	Battery Type	Lifespan	Charging Time	Disposal Method
G2H	6500mAh Li-ion	12-18 months	5 hours	E-waste facility
H1	2x CR2450	6-9 months	N/A (replace)	Coin-cell recycling
D100	5200mAh Li-ion	2 years	4 hours	E-waste facility
