When the battery no longer holds a charge, Aqara offers replacement services, though they can be costly.

The G3’s removable 18650 battery offers more flexibility. Aqara’s official battery is reliable, but third-party options can be more economical. When selecting third-party 18650 batteries, consider the following:

• Capacity (mAh): Aim for 2600mAh or higher. Lower-capacity batteries (e.g., 2200mAh) may reduce runtime.
• Protection Circuit: Essential for safety. Look for batteries with built-in overcharge, over-discharge, and short-circuit protection.
• Brand Reputation: Stick with reputable brands like Panasonic, Samsung, LG, or Sony. Avoid no-name brands from untrusted sellers.
• Chemistry: Use ICR (lithium cobalt oxide) or INR (lithium manganese nickel) types. Avoid IMR (manganese) for high-drain devices like doorbells.

Example: A user in Seattle reported that after switching from a generic 18650 to a Samsung 26H (2600mAh, INR chemistry), their G3’s battery life increased from 4 weeks to 6 weeks under similar usage conditions.

AA Batteries for the Wireless Doorbell

The Aqara Wireless Doorbell uses two AA batteries, and the choice here is surprisingly impactful. While it doesn’t stream video, it still performs motion detection and sends notifications, which drain power over time.

• Alkaline AA: Common and affordable, but last only 2–3 months with regular use. Prone to leakage over time, which can damage the device.
• Lithium AA: More expensive upfront but last 4–6 months and perform better in extreme temperatures (ideal for outdoor use). Brands like Energizer Ultimate Lithium are highly recommended.
• Rechargeable NiMH AA: Eco-friendly and cost-effective over time. However, they have lower voltage (1.2V vs. 1.5V) and may not provide consistent power, especially in cold weather. Use only high-capacity (2500mAh+) NiMH batteries with a smart charger.

Tip: For the Wireless Doorbell, lithium AA batteries are the best balance of longevity, reliability, and performance. Avoid mixing battery types or brands, as this can lead to uneven discharge and potential damage.

Battery Longevity: Real-World Usage Scenarios

Battery life isn’t just about capacity—it’s influenced by usage patterns, environmental conditions, and settings. Here’s how different factors affect runtime:
