Identifying Your Aqara Doorbell Model and Battery Type

Why Model Identification Is Crucial

Before you even think about changing the battery, it’s essential to identify your specific Aqara Doorbell model. Different models use different battery types, and using the wrong one can damage your device or void the warranty. The most common Aqara Doorbell models include:

• Aqara Doorbell G2H (Camera Hub) – Uses a built-in 5100mAh rechargeable lithium-ion battery
• Aqara Doorbell G3 (Camera Hub Pro) – Features a 6400mAh lithium-ion battery with USB-C charging
• Aqara Doorbell H1 Pro – Uses a removable 21700 lithium-ion battery (3.7V, 5000mAh)

Each model has a unique battery configuration. For instance, the G2H and G3 have internal batteries, meaning you’ll need to charge them in place or remove the entire unit for charging. The H1 Pro, on the other hand, allows for a removable battery—making battery swaps much more convenient.

How to Check Your Model and Battery Specs

To confirm your model:

1. Check the back or bottom of the doorbell unit—most models have a label with the model number (e.g., DCH-M01 for G2H, DCH-M02 for G3, DCH-M03 for H1 Pro).
2. Open the Aqara Home app → go to “Devices” → select your doorbell → tap “Device Info.” The model name and firmware version will be displayed.
3. For battery specs, refer to the original packaging or user manual. Alternatively, visit the official Aqara website and search by model number.
