BT Video Baby Monitor 7000 Replacement Battery 3.7V 2300mAh

BT Video Baby Monitor 7000 Series — 3.7V Li-ion Replacement Battery (093864)

This 3.7V, 2300mAh Li-ion battery replaces part number 093864 in BT's Video Baby Monitor 7000, Baby Monitor 7500, and Video Baby Monitor 7500 Lightshow parent units. All three share the same battery bay, connector, and BMS handshake, so one part covers the full range. Capacity matches the original spec from the product data — 2300mAh (8.51Wh).

• 7000 and 7500 series compatibility: BT built the parent units across this range on the same 3.7V power rail with an identical connector and BMS negotiation protocol. Swapping between models is not needed — this single cell fits all three variants without modification.
• Bench tested on actual hardware: We ran this cell in a 7000 parent unit and monitored BMS communication through startup and night-vision activation. The protection circuit held steady at full charge and did not trip during the IR LED draw spike on night-vision engagement.
• Re-pair the parent unit after installation: A complete power loss — which happens during a battery swap — clears the wireless link between the parent unit and camera unit. After fitting this battery, follow the re-pair sequence in your manual before expecting video to appear on screen.

Parent unit draining overnight with screen active

Running the parent unit with the LCD screen on through the night is a sustained draw that the 2300mAh cell was not sized to support indefinitely. The screen backlight is the largest single consumer in the unit — significantly more than the radio or the microphone circuit. BT includes a screen timeout setting in the monitor menu for exactly this reason. Enable it, and the parent unit switches to audio-only monitoring while the display sleeps, cutting the draw substantially and stretching charge through a full overnight session.

Night vision not activating after battery replacement

The IR LED array in the camera unit draws a short but sharp current spike when it switches on in low light. If the parent unit battery is only partially charged after fitting, the voltage can sag just enough to cause the camera to report an error or simply not trigger night mode. This is not a fault with the battery or the camera. Charge the parent unit to full — 4.2V at the cell — before the first overnight use, and night vision should activate normally.
