Oricom Secure SC850 Replacement Battery 3.8V 2100mAh

Oricom Secure SC850 — 3.8V Li-ion Replacement Battery (55070)

This 3.8V 2100mAh Li-ion battery replaces the original 55070 cell in the Oricom Secure SC850 baby monitor parent unit. It powers the portable handset that handles wireless audio transmission between you and the camera unit. When the original cell degrades, this replacement restores the parent unit to full operating capacity.

• SC850 parent unit fit: The SC850 parent handset runs on a single slim 3.8V Li-ion cell at 63.00 x 50.50 x 5.40mm. This exact footprint and voltage match the connector and BMS handshake on the original board — no modification needed.
• Bench tested on actual hardware: We ran the SC850 parent unit through charge cycles and monitored the BMS response. The protection circuit tripped correctly on over-discharge and accepted charge without faults on a standard SC850 base station.
• Re-pair after installation: The SC850 parent unit loses its wireless link to the camera unit when power is fully interrupted. After fitting the new battery, hold the pair button on both units until the link indicator confirms the connection is re-established.

Parent unit battery draining overnight during monitoring

Running the SC850 parent unit through the night with the screen active is a sustained high-draw state — the LCD backlight and radio receiver pull continuously. Most overnight drain complaints trace to the screen timeout being disabled. Go into the parent unit display settings and set the screen to auto-off after 30–60 seconds. The unit continues transmitting audio with the screen off, so you lose no monitoring function. This change alone significantly reduces overnight draw on the 2100mAh cell.

Night vision feed not appearing after battery replacement

The SC850 camera unit's IR LEDs are powered independently from the camera side, but the parent unit requires adequate voltage to render and display the IR feed correctly. If night vision appears blank or scrambled immediately after a battery swap, the new cell may not yet be at sufficient charge. Charge the parent unit to full on the base station before testing night vision — the display-side processing needs a stable voltage above 3.6V to handle the IR signal. Do not assess night vision performance on a freshly installed, partially charged cell.
