Warning: Avoid generic or “universal” batteries. They may not provide consistent voltage, leading to erratic behavior or damage to the doorbell’s internal circuitry.
Step-by-Step Battery Replacement Process
Step 1: Power Down and Prepare the Area
Before handling your doorbell, turn off the power if it’s a wired model (even if it has a battery backup). For battery-only models, simply ensure the device is inactive. Clean the area around the doorbell with a dry cloth to prevent dust from entering the unit. If your doorbell is mounted on a textured wall, consider placing a small towel beneath it to catch any falling screws.
Example: One user reported that a grain of sand entered the battery compartment and caused intermittent contact issues. A quick wipe-down with a microfiber cloth prevented this.
Step 2: Remove the Doorbell from the Mount
Most Aqara doorbells use a quick-release mounting system. Here’s how to remove them:
- G2H/G2H Pro Models: Look for a small screw at the bottom of the doorbell. Use your Phillips screwdriver to loosen it (don’t remove it entirely). Then, slide the doorbell upward to detach it from the wall plate.
- H1 Model: The H1 often has a magnetic or snap-on mount. Gently pull the device downward or wiggle it side-to-side to release it. No tools required.
Tip: If the doorbell feels stuck, check for hidden screws or use a plastic spudger to gently pry it loose. Never use metal tools—they can scratch the casing or damage internal components.
Step 3: Open the Battery Compartment
Once removed, locate the battery compartment:
- G2H Series: The battery pack is on the back. Slide the compartment cover downward or remove the retaining screw (if present). Pull out the battery pack.
- H1 Model: The battery tray is on the side or bottom. Use your thumb to slide the tray open. Two CR123A batteries will be visible, held in place by a spring mechanism.
Important: Note the battery orientation. Look for “+” and “-” symbols on the tray. Incorrect insertion can damage the device.
Step 4: Replace or Recharge the Batteries
Follow these steps based on your model:
- For G2H (Rechargeable Battery):
- Remove the battery pack.
- Recharge it using a USB-C cable for 3–4 hours (until the LED indicator turns solid green).
- Reinsert the pack, ensuring it clicks into place.
- For H1 (CR123A Batteries):
- Remove the old batteries and dispose of them responsibly (recycling centers or battery drop-offs).
- Insert two new CR123A batteries, matching the polarity marks.
- Push the tray back into the doorbell until it’s flush.
Pro Tip: For the H1, label the batteries with the installation date using a permanent marker. This helps you track usage and plan replacements.
Step 5: Reassemble and Reattach the Doorbell
After replacing the batteries:
- Close the battery compartment securely.
- For G2H models, re-tighten the security screw at the bottom.
- Align the doorbell with the mounting plate and slide it downward or snap it into place.
- Ensure the device is flush with the wall and doesn’t wobble.
Note: If the doorbell has a tamper-proof feature, the Aqara app may send a “tamper alert” when it’s reattached. Simply acknowledge it in the app.
Troubleshooting Common Issues
Doorbell Not Powering On After Replacement
If your doorbell doesn’t turn on, don’t panic. Try these fixes:
- Check Battery Polarity: Remove and reinsert the batteries, ensuring the “+” and “-” ends match the tray markings.
- Clean Battery Contacts: Use a cotton swab dipped in rubbing alcohol to wipe the metal contacts in the compartment. Dirt or corrosion can prevent power flow.
- Test with a Multimeter: Measure the battery voltage. CR123A batteries should read ~3V. Rechargeable packs should show ~3.7V.
- Reset the Device: Press and hold the reset button (usually on the side) for 10 seconds. This clears any firmware glitches.
Real-World Example: A user in Arizona reported that extreme heat caused the battery pack to expand slightly. Cleaning the contacts and reinserting it solved the issue.
App Not Detecting the Doorbell
If the Aqara app shows “offline” or “disconnected”:
- Restart the doorbell by pressing the reset button.
- Ensure your home Wi-Fi is stable. Aqara doorbells require a 2.4GHz network (not 5GHz).
- Move your router closer temporarily to boost signal strength.
- Re-pair the device in the Aqara app: Go to “Add Device” > “Doorbell” and follow the on-screen instructions.
Tip: For G2H models, ensure the battery pack is fully charged. A low battery can cause connectivity issues.
Video Quality or Audio Problems
After replacing batteries, you might notice:
- Fuzzy or Pixelated Video: This could be due to a weak Wi-Fi signal. Use the Aqara app’s “Wi-Fi Signal Strength” tool to check. If below 70%, consider a Wi-Fi extender.
- Delayed Audio or Echo: Update the doorbell’s firmware in the app. Go to “Device Settings” > “Firmware Update”.
