To identify your model, check the device’s label (usually on the back or bottom), refer to your purchase receipt, or open the Aqara app. The app typically displays the model name under “Device Info” or “Settings.” Knowing your model ensures you purchase the correct batteries and follow the right procedure.

Choosing the Right Batteries: Types and Recommendations

Using the wrong battery type can damage your doorbell or shorten its lifespan. Here’s what you need to know:

• AA Batteries (for H1 Battery Version): Opt for alkaline or lithium AA batteries. Avoid zinc-carbon batteries, as they drain quickly. Lithium AA batteries (e.g., Energizer Ultimate Lithium) last 2–3 times longer and perform better in extreme temperatures.
• CR2032 Coin Cell (for H1 Wired Version): A standard 3V lithium coin battery. Replace it every 6–12 months, even if the main power is wired.
• Rechargeable Lithium-Ion (for G2H Pro/G3): These are built-in, so you’ll need to charge them via USB-C. For extended use, consider carrying a portable power bank or setting a charging schedule.

Pro Tip: For AA-powered models, use batteries from the same brand and batch to ensure balanced discharge. Mixing old and new batteries can cause leaks or reduced performance.

How Long Do Aqara Doorbell Batteries Last?

Battery life varies based on usage, environmental conditions, and settings. Here’s a general estimate:

• AA Alkaline Batteries (H1): 4–6 months (with moderate use: ~10–15 activations/day).
• AA Lithium Batteries (H1): 8–12 months (same usage).
• Rechargeable (G2H Pro/G3): 2–3 months (with 10–15 activations/day and 720p resolution).

Factors that reduce battery life include:

• High-resolution video (1080p vs. 720p)
• Frequent motion detection alerts
• Extreme temperatures (below 0°C or above 40°C)
• Wi-Fi signal strength (weak signals increase power consumption)

Optimizing Battery Life: Tips and Best Practices

Adjusting Motion Detection Sensitivity

Motion detection is a major battery drain. To optimize:

• In the Aqara app, go to Settings > Motion Detection.
• Reduce sensitivity from “High” to “Medium” or “Low” if you live in a busy area (e.g., near a street).
• Set Activity Zones to ignore irrelevant areas (e.g., tree branches).
• Enable Smart Detection (if available) to ignore animals or vehicles.

Example: A user in a suburban neighborhood reduced motion alerts by 60% by excluding a nearby sidewalk and lowering sensitivity.

Managing Video Quality and Storage

Higher resolutions and longer recordings consume more power:

• Set video quality to 720p instead of 1080p.
• Shorten clip duration (e.g., 15 seconds instead of 30).
• Use Cloud Storage (if subscribed) to avoid frequent SD card writes.
