If you notice two or more of these symptoms, a battery replacement is likely in order. Ignoring them may result in missed deliveries, failed motion detection, or complete device failure.

Tools and Materials You’ll Need

Essential Tools for Opening the Doorbell

Opening the Aqara Doorbell isn’t a brute-force task. It requires precision and the right tools to avoid damaging the housing, camera lens, or internal connectors. Here’s a list of what you’ll need:

• Precision screwdriver set (especially 2.0mm Phillips and 1.5mm flathead)
• Plastic pry tools (nylon spudgers) – essential for separating the plastic casing without scratches
• Heat gun or hairdryer – to soften adhesive seals (if present)
• Anti-static wrist strap (recommended) – to prevent electrostatic discharge that could damage sensitive electronics
• Small container or magnetic tray – to store screws and prevent loss
• Magnifying glass or phone macro lens – helpful for inspecting tiny connectors

While some users attempt to use metal spudgers or knives, we strongly advise against it. The plastic housing is delicate, and metal tools can easily mar the surface or damage internal ribbon cables.

Where to Buy Replacement Batteries

Replacement batteries are available from several trusted sources:

• Official Aqara Store (Amazon, Aqara.com) – Most reliable, but often more expensive
• Authorized resellers (e.g., B&H, Newegg) – Good quality with warranty support
• Third-party brands (e.g., Cameron Sino, TaehaMe) – Affordable and well-reviewed, but verify compatibility

When purchasing, ensure the battery includes a protection circuit to prevent overcharging, over-discharging, and short circuits. This is a non-negotiable safety feature.

Optional but Helpful Add-ons

• Isopropyl alcohol (90%+) – for cleaning adhesive residue
• Double-sided adhesive tape or foam tape – for resealing the housing if original seal is damaged
• Needle-nose pliers – for gently disconnecting battery connectors
• Workbench mat – to keep your workspace clean and static-free

Pro Tip: Before starting, charge your new battery fully using a compatible charger. This ensures you can test the doorbell immediately after reassembly.

Step-by-Step Guide: How to Open Aqara Doorbell to Replace Battery

Step 1: Power Down and Remove from Mounting Bracket

Begin by powering off the doorbell via the Aqara app or by removing it from the Wi-Fi network. This prevents any data corruption during disassembly. Next, detach the doorbell from its mounting bracket. Most Aqara models use a quick-release mechanism — simply slide the unit upward or press a release tab. If it’s hardwired, do not disconnect the wiring; just remove the main unit, leaving the base plate in place.

Place the doorbell face-down on a soft surface (like a microfiber cloth) to protect the camera lens and front panel.

Step 2: Locate and Remove the Screws

Flip the doorbell over and inspect the back panel. On most models, you’ll find two to four small screws hidden under rubber feet or silicone plugs. Use a precision screwdriver to remove them. For example:

• G2H: Two 2.0mm Phillips screws under rubber feet
• D100: Three screws, one under a silicone plug near the charging port

Store the screws in your magnetic tray. Do not lose them — they are critical for reassembly.

Step 3: Soften Adhesive Seals (If Required)

Some Aqara models use adhesive to seal the housing for weather resistance. To avoid cracking the plastic, apply gentle heat (100–150°F / 38–65°C) using a hairdryer or heat gun for 1–2 minutes. Focus on the edges where the front and back panels meet. This softens the adhesive, making prying easier.

Caution: Do not overheat — excessive heat can warp plastic or damage internal components.

Step 4: Carefully Pry Open the Housing

Insert a plastic spudger into the seam between the front and back panels, starting at the bottom edge. Gently twist to create a small gap. Work your way around the perimeter, using multiple spudgers to maintain even pressure. Never force the case open — if resistance is high, apply more heat.

On the G2H Pro, you may need to disconnect the internal microphone ribbon cable before fully separating the halves. Use a spudger to lift the ZIF (zero insertion force) connector tab and slide the cable out.

Step 5: Disconnect and Remove the Old Battery

Once the housing is open, locate the battery. It’s usually secured with adhesive or a small plastic bracket. Carefully peel back the adhesive using a spudger, then disconnect the battery connector by lifting the ZIF tab and gently pulling the cable. Do not yank the wires.

Remove the old battery and dispose of it properly at a certified e-waste facility. Lithium-ion batteries should never be thrown in regular trash.

Step 6: Install the New Battery

Align the new battery in the same orientation as the old one. Secure it with a small piece of double-sided tape if the original adhesive is worn. Reconnect the battery cable by sliding it into the connector and pressing the ZIF tab down until it clicks.

Double-check that the battery is seated properly and all connectors are secure before proceeding.

Reassembling the Aqara Doorbell

Step 1: Reconnect Internal Components

If you disconnected any ribbon cables (e.g., microphone, speaker, or camera), now is the time to reconnect them. Ensure each cable is fully inserted and the ZIF tab is locked. Misaligned cables can cause audio/video failure or no power at all.

Step 2: Close the Housing and Secure Screws

Carefully align the front and back panels. Press them together firmly but gently. Reinsert all screws and tighten them securely — but don’t over-torque, as this can strip the plastic threads.

For models with adhesive seals, consider applying a thin layer of weather-resistant silicone sealant around the edge for added protection against moisture.

Step 3: Reattach to Mounting Bracket

Slide the doorbell back onto its mounting bracket until it clicks into place. If it’s hardwired, ensure the connection is secure. Power on the device via the Aqara app or by reconnecting to Wi-Fi.

Step 4: Test Functionality

Perform a full test:

• Check live video feed in the Aqara app
• Test two-way audio by speaking through the app
• Trigger motion detection (wave your hand in front)
• Verify night vision and infrared LEDs
• Confirm battery level shows in the app

If any function fails, power off and recheck your connections. A loose battery cable is the most common culprit.

Common Mistakes and Troubleshooting Tips

Mistake 1: Forcing the Case Open

Using excessive force or metal tools can crack the housing or damage internal components. Always use plastic pry tools and apply heat if the seal is tight. If you encounter resistance, stop and reassess — patience is key.

Mistake 2: Damaging Ribbon Cables

Ribbon cables are fragile. Never pull them by the wires. Use the ZIF tab to disconnect and reconnect. If a cable tears, repair is difficult and often requires professional soldering.

Mistake 3: Using Incompatible Batteries

As mentioned earlier, using a battery with incorrect voltage or missing protection circuits can damage the doorbell. Always verify specifications. A 3.7V 3,000mAh battery for a G2H Pro is not the same as a 3.7V 2,600mAh battery — capacity affects charging cycles and performance.

Mistake 4: Skipping the Adhesive Seal

Reassembling without a proper seal compromises weather resistance. If the original adhesive is damaged, use high-quality foam tape or silicone sealant rated for outdoor use.
