Why Battery Replacement Matters for Your Aqara Doorbell

Understanding the importance of timely battery replacement is the first step toward maintaining your Aqara Doorbell’s performance. Unlike hardwired doorbells, the Aqara model relies entirely on a rechargeable lithium-ion battery pack for operation. When the battery runs low, several critical functions begin to degrade, potentially compromising your home security.

Impact of a Low Battery on Doorbell Performance

• Reduced video quality: As battery levels drop below 20%, the doorbell may automatically lower video resolution to conserve power, resulting in blurry or pixelated footage.
• Delayed notifications: The device may take longer to send alerts to your smartphone or tablet, increasing the risk of missing real-time events.
• Motion detection lag: Sensors may become less responsive, especially during peak usage hours, leading to missed recordings of visitors or potential intruders.
• Complete shutdown: If the battery is allowed to fully deplete, the doorbell will shut down entirely, leaving your front door unmonitored.

Signs It’s Time to Replace the Battery

Your Aqara Doorbell will notify you when it’s time to recharge or replace the battery. These indicators include:

• A persistent low-battery alert in the Aqara Home or Apple Home app (usually below 15%).
• The LED indicator on the doorbell flashes red or blinks rapidly.
• Reduced responsiveness in live view or delayed video playback.
• The device fails to connect to your Wi-Fi network, often due to low power affecting the radio module.

Pro Tip: To avoid sudden outages, proactively check your battery level once a month using the Aqara app. This simple habit can prevent unexpected downtime and ensure your home remains under constant surveillance.

Tools and Materials You’ll Need

Before you begin the battery replacement process, gathering the right tools and materials ensures a smooth and safe experience. The good news is that you won’t need specialized equipment—most of what you need is likely already in your home toolkit.

Essential Tools and Supplies

• Replacement battery: The Aqara Doorbell uses a proprietary 18650 lithium-ion battery pack (model: Aqara B1). It’s not a standard AA or AAA battery. You can purchase genuine replacements from Aqara’s official website, Amazon, or authorized smart home retailers. Using third-party or non-certified batteries may void your warranty and pose safety risks.
• Small Phillips-head screwdriver: Most Aqara Doorbell models are secured with a single tamper-resistant screw on the bottom edge. A precision screwdriver (size #0 or #1) is ideal for this task.
• Plastic pry tool (optional but recommended): A non-metallic spudger or guitar pick helps gently separate the doorbell from its mounting bracket without scratching the surface.
• Microfiber cloth: Useful for cleaning the doorbell’s lens and housing after removal.
• Charging cable and adapter: While not required for replacement, you’ll need them to recharge the new battery before installation.

Where to Buy the Correct Battery

When sourcing your replacement battery, always opt for genuine Aqara parts. Counterfeit batteries may be cheaper but often have lower capacity, reduced lifespan, and safety hazards such as overheating or swelling. Here are trusted sources:

• Aqara Official Website: Offers authentic batteries with warranty support.
• Amazon (sold by Aqara or authorized resellers): Look for “Fulfilled by Amazon” and verified purchase reviews.
• Smart home specialty stores: Retailers like The Smart Home Store, Smart Home Supply, or local home automation shops often stock genuine components.

Pro Tip: Consider purchasing a backup battery. This way, you can swap out the old one immediately and recharge the spare for future use—minimizing downtime.

Step-by-Step Guide: How to Change Aqara Battery Doorbell

Now that you’re equipped with the right tools, let’s dive into the five easy steps to replace your Aqara Battery Doorbell’s power source. Follow these instructions carefully to avoid damaging the device or compromising its weather resistance.

Step 1: Power Down and Prepare the Doorbell

Before touching the doorbell, ensure it’s powered down to prevent accidental activation or short circuits. Although the device runs on low-voltage DC power, safety first.

• Open the Aqara Home app or Apple Home app.
• Locate your doorbell and tap “Settings” > “Device Information.”
• Check the battery level. If it’s below 10%, proceed with replacement.
• Optionally, take a screenshot of your current settings (Wi-Fi network, motion zones, etc.) for easy reconfiguration later.

Tip: Perform this task during daylight hours for better visibility, especially if you’re working outdoors.

Step 2: Remove the Mounting Screw

The doorbell is secured to its bracket with a single screw located at the bottom edge. This screw prevents tampering and accidental removal.

• Use your Phillips-head screwdriver to unscrew the tamper-proof screw.
• Set the screw aside in a small container or magnetic tray to avoid losing it.
• Do not force the doorbell upward yet—the screw is the only fastener, but the housing is designed to snap into place.

Note: Some early Aqara Doorbell models use a Torx screw. If you encounter resistance, double-check the screw type and use the appropriate driver.

Step 3: Gently Detach the Doorbell from the Bracket

With the screw removed, the doorbell should now be loose but still attached via the internal connectors.

• Insert a plastic pry tool between the doorbell and the mounting bracket at the top edge.
• Gently wiggle the tool to release the top clip.
• Once the top is free, pull the doorbell straight down to disengage the bottom hinge.
• Support the doorbell with your other hand to avoid dropping it.

Caution: Avoid using metal tools or excessive force. The plastic housing is durable but can crack under pressure.

Step 4: Open the Battery Compartment

The battery is housed inside a sealed compartment at the back of the doorbell. This design protects it from weather and tampering.

• Locate the small latch or groove on the back panel.
• Use your fingers or a plastic tool to slide the latch and release the cover.
• Carefully remove the cover to expose the battery pack.
• Note the orientation of the battery—positive (+) and negative (-) terminals are clearly marked.

Tip: Take a photo of the battery’s position before removing it. This ensures correct reinstallation.

Step 5: Replace the Battery and Reassemble

Now comes the core of the process: swapping the old battery for the new one.

• Grasp the old battery and pull it out gently. It may be snug, but it should slide out easily.
• Insert the new, fully charged Aqara battery in the same orientation as the old one.
• Ensure the battery is seated properly—there should be no wobbling or gaps.
• Snap the back cover back into place until you hear a click.
• Reattach the doorbell to the mounting bracket by aligning the bottom hinge and pushing the top until it clicks.
• Reinsert and tighten the tamper-proof screw securely.

Final Check: Gently tug on the doorbell to confirm it’s firmly attached.

Reconnecting and Reconfiguring Your Doorbell

With the new battery installed, your Aqara Doorbell should power on automatically. However, a few additional steps ensure optimal performance and connectivity.

Power-On and Initial Setup

• Wait 30–60 seconds for the doorbell to boot up. The LED indicator will flash blue during initialization.
• Open the Aqara Home app or Apple Home app.
• Check if the doorbell appears in the device list. If not, tap “Add Accessory” and follow the on-screen instructions.
• Verify that the Wi-Fi connection is stable. The doorbell uses 2.4 GHz networks only.

Restore Custom Settings

If you didn’t take a screenshot earlier, now is the time to reconfigure:

• Set motion detection zones to avoid false alerts from trees or pets.
• Adjust video quality (1080p is recommended for clear footage).
• Enable two-way audio and night vision if disabled.
• Reconnect to smart home routines (e.g., “When doorbell rings, turn on porch light”).

Test Functionality

• Press the doorbell button to trigger a live view.
• Verify that notifications arrive instantly on your phone.
• Check the battery level in the app—it should show 100% or the current charge level.
• Walk in front of the doorbell to test motion detection.

Pro Tip: If the doorbell fails to reconnect, perform a soft reset by holding the reset button (usually inside the battery compartment) for 10 seconds. Then re-pair via the app.

Battery Maintenance and Longevity Tips

Replacing the battery is only one part of the equation. To maximize your Aqara Doorbell’s lifespan and performance, adopt a proactive maintenance routine.

Optimize Battery Life

• Limit motion detection zones: Narrowing the detection area reduces unnecessary recordings and conserves battery.
• Adjust recording duration: Set the video clip length to 10–15 seconds instead of 30 seconds.
• Disable continuous recording: Only enable 24/7 recording if absolutely necessary.
• Use Wi-Fi efficiently: Ensure your router is within 30 feet of the doorbell to reduce signal strain.

Charging Best Practices

• Charge the battery using the original Aqara USB-C cable and a 5V/1A or 5V/2A adapter.
• Avoid overcharging. Unplug the battery once it reaches 100%.
• Store spare batteries at 40–60% charge if not in use for extended periods.
• Charge in a cool, dry place—never in direct sunlight or near heat sources.

When to Consider a Hardwired Setup

If you frequently replace batteries or live in an area with high visitor traffic, consider upgrading to a hardwired solution. Aqara offers optional wired power adapters that connect to existing doorbell wiring, providing continuous power and eliminating battery swaps altogether.

Battery Type	Capacity (mAh)	Expected Lifespan (Cycles)	Recommended Charger	Warranty
Aqara B1 (Original)	3000	500	Aqara USB-C (5V/2A)	12 months
Third-Party (Generic)	2800–3200	200–300	Any USB-C	None
Aqara B1 (Extended)	4000	400	Aqara USB-C (5V/2A)	12 months

As shown in the table above, genuine Aqara batteries offer superior longevity and safety. While third-party options may seem economical, they often degrade faster and pose risks to your device.
