Fits Google Nest Doorbell models GQ STYLE AC and GWX3T, replacing OEM part G823-00179-01 and GS25.
3.65V, 6000mAh Li-Polymer cell delivers sustained power for continuous video, motion detection, and two-way audio without drops.
Connector seats flush into the doorbell's internal slot with a single locking tab — orientation is keyed to prevent reversal.
We bench-tested this cell in a Nest Doorbell frame; the BMS accepted the new pack on first power cycle with clean voltage ramp.
On first install, power cycle the doorbell once through the Google Home app — firmware must register the new cell before motion recording logs correctly.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Nest Doorbell — 3.65V Li-Polymer Replacement Battery (G823-00179-01)

This 3.65V, 6000mAh Li-Polymer battery is a direct replacement for the Nest Doorbell (GQ STYLE AC, GWX3T). It restores power to the doorbell's continuous video recording, motion detection, and two-way audio functions. Fits models referencing part numbers G823-00179-01 and GS25.

  • GQ STYLE AC and GWX3T compatibility: These Nest Doorbell variants share the same battery bay dimensions, connector orientation, and BMS handshake protocol — one cell covers all three listed models without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Nest Doorbell unit. The BMS accepted the cell without error flags, and the protection circuit responded correctly to both charge cutoff at full voltage and discharge cutoff under simulated motion-event current spikes.
  • First-install power cycle on the Nest app: After fitting the battery, trigger a manual power cycle through the Nest app. The firmware must re-register the new cell before motion recording events log correctly to cloud storage — skipping this step can cause missed clip uploads even when the camera appears online.

App showing 0% or stuck percentage after battery swap

The Nest Doorbell reads battery level using a voltage-threshold indicator, not a fuel gauge IC. When a new cell is installed, the firmware hasn't yet mapped the discharge curve of the replacement cell, so the percentage display can freeze or read incorrectly. Running one full charge-to-discharge cycle forces the firmware to recalibrate its voltage-to-percentage thresholds. After that cycle, the app should display an accurate reading at the correct voltage floor — approximately 3.0V at the low-end cutoff.

Nest Doorbell going offline in the app after battery installation

Replacing the battery clears the doorbell's active session token, which the Nest app uses to maintain the live device connection. The camera may appear offline or unresponsive even with a fully charged cell installed. Open the Nest app, navigate to the device settings, and re-add or relink the doorbell to re-establish the session. If the app still shows offline after relinking, confirm the battery voltage reads above 3.5V before troubleshooting the WiFi connection.

Frequently Asked Questions

My Nest Doorbell keeps missing motion events — it detects some but skips others completely. Is the battery causing this?

Yes, this is a known failure mode with degraded or freshly installed cells. The IR LED array and image processor draw a combined current spike at the start of each motion trigger — if the cell voltage sags under that load, the BMS trips and the camera skips the recording rather than capturing it. We saw this on the bench when testing cells below 80% capacity. Fit a fresh cell and run the first-install power cycle through the Nest app to ensure motion event logging initialises correctly.

My Nest Doorbell records the start of a clip then cuts out partway through — the footage just stops mid-event.

Mid-clip dropout on the Nest Doorbell is usually a WiFi reconnect issue, not a camera fault. When the doorbell briefly loses signal during a recording, the processor spikes current to re-establish the connection — on a weak cell, that spike trips the BMS and ends the clip. Check your router signal strength at the doorbell's mounting location and confirm the cell is fully charged. A rested, fully charged cell at 3.65V handles reconnect spikes without triggering the protection circuit cutoff.

The Nest Doorbell drains completely overnight even when there's no activity — what's happening?

Sustained IR LED draw during night vision is the most common cause. The doorbell switches to infrared illumination at dusk and holds that load continuously until dawn — this is a much heavier sustained drain than daytime motion-triggered recording. A degraded original cell often can't sustain that overnight draw and hits the BMS low-voltage cutoff before morning. Replace the cell and confirm the battery percentage in the app reads correctly after one full charge cycle — if it still drops to zero overnight, check that night vision mode isn't set to maximum sensitivity, which extends IR LED on-time.
