IQ America VD-8810 Replacement Battery 3.6V 700mAh H-AAAJ3

IQ America VD-8810 — 3.6V Ni-MH Replacement Battery (H-AAAJ3)

This is a 3.6V 700mAh Ni-MH replacement battery for the IQ America VD-8810 wireless video doorbell. It matches the original H-AAAJ3 cell in voltage, chemistry, and form factor. When the factory battery degrades, this swap restores the camera module to full operation without replacing the entire doorbell unit.

• VD-8810 platform fit: The VD-8810 runs its camera module, IR LEDs, and RF transmitter from a single 3.6V Ni-MH cell. That shared voltage rail means chemistry matters — substituting a Li-ion cell at a higher nominal voltage will overstress the onboard regulation circuit.
• Bench tested on actual hardware: We cycled this cell through motion-trigger sequences and confirmed the BMS holds stable across the combined current draw of the processor waking, the IR LEDs firing, and the RF module transmitting simultaneously.
• First-install power cycle on the VD-8810: After fitting the new cell, press the doorbell button once to wake the unit fully, then allow the firmware to complete one full wake-sleep cycle before testing motion recording. Skipping this step can leave the motion log misaligned with the new cell's charge state.

Camera going offline in the app after battery swap on the VD-8810

Replacing the battery cuts power to the VD-8810's wireless module, which drops the active session token the app holds. The camera comes back online at the hardware level, but the app doesn't automatically re-establish the authenticated link. Open the app, navigate to the device list, and manually trigger a reconnect or re-register the doorbell. If the unit still shows offline, confirm the cell voltage has recovered above 3.2V — below that, the RF transmitter won't sustain a stable connection.

App reporting 0% or no charge indicator after fitting the H-AAAJ3

The VD-8810 uses a voltage-threshold indicator, not a fuel gauge IC. It reads charge state by comparing cell voltage against fixed thresholds — not by tracking charge in and out. A freshly installed cell sitting at mid-state-of-charge can read as 0% until the firmware samples voltage after a complete charge and discharge pass. Charge the unit fully through its normal dock or adapter, let it run through one motion-triggered wake cycle, and the percentage will update to reflect the actual cell state.
