Oricom SC875 Baby Monitor Compatible Battery 3.8V 2400mAh

Oricom SC875 — 3.8V Li-Polymer Replacement Battery

This 3.8V 2400mAh (9.12Wh) Li-Polymer battery replaces the parent unit battery in the Oricom SC875 baby monitor. It fits the parent handset — the unit you carry around the house while the camera stays in the child's room. Swap it in when the original no longer holds enough charge to get through a night shift.

• SC875 parent unit fit: The SC875 parent unit runs a 3.8V Li-Polymer cell at this exact footprint — 75.10 x 54.80 x 4.80mm. The slim 4.80mm profile is tight inside the housing, so dimensional accuracy matters more here than in most consumer devices.
• Bench tested on actual hardware: We ran the cell through charge and discharge cycles and confirmed the BMS holds cutoff correctly at the low-voltage threshold. The cell reaches rated capacity without overcharge on the SC875 dock.
• Wireless re-pair after replacement: The SC875 parent unit drops its link to the camera unit when it loses power completely. After fitting this battery, charge it before powering on — then re-pair the parent unit with the camera following the SC875 pairing sequence in the manual.

Parent unit not connecting to the camera unit after battery swap

When the parent unit drops to zero volts — which happens during a battery replacement — it loses the stored pairing data for the camera unit. The SC875 uses a radio handshake between the two units, and that link does not restore automatically on power-up. You need to run the manual pairing sequence: hold the pair button on the camera unit, then initiate pairing from the parent unit menu. Do this with the parent unit charged above 3.6V so the radio module has enough voltage to complete the handshake.

Night vision stops working after fitting a new battery

The SC875 camera unit handles night vision, but the parent unit display needs enough voltage to render the IR feed correctly — a low parent battery causes the screen to drop brightness or cut the night vision stream entirely. If the display looks washed out or the night mode icon disappears, the parent unit cell is likely under-charged rather than faulty. Charge the new battery fully before testing night vision. A rested cell sitting at 3.8V nominal should resolve the display issue without any further adjustment.
