Oricom SC870 Replacement Battery 3.7V 2300mAh 093864

Oricom SC870 / SC860 — 3.7V Li-ion Replacement Battery (093864)

This 3.7V 2300mAh Li-ion battery replaces the OEM part 093864 in the Oricom SC870 and SC860 parent units. It fits the handheld parent unit of these two-way baby phone systems — not the nursery camera unit. Voltage and capacity match the original specification exactly.

• SC870 and SC860 parent unit fit: Both models share the same parent unit housing, battery bay dimensions, and 3.7V power rail. The connector pinout and BMS handshake are identical across the two, so one cell covers both.
• Bench tested on actual hardware: We ran this cell through charge cycles on the SC870 parent unit. The BMS accepted charge without fault flags, held voltage steady through the display-on and audio transmission draw, and cut off cleanly at the low-voltage threshold.
• Re-pair after power interruption: When the parent unit drops to zero voltage during a battery swap, it loses its wireless link to the nursery unit. After fitting the new cell, hold the pairing button on the parent unit and follow the SC870 pairing sequence before placing it in the room.

Parent unit battery draining overnight with the SC870

Running the SC870 parent unit all night with the screen active is a sustained high draw on a 3.7V cell. The backlit display, audio receiver, and VOX circuit all pull current simultaneously. On an aged or partially charged cell, voltage sags below the unit's operating threshold well before morning. Enable the screen timeout in the SC870 menu so the display cuts after a few seconds — the audio and VOX remain active, but the display draw drops out.

Range drops noticeably after fitting a new battery

The SC870's radio transmitter is voltage-sensitive — output power tracks the supply rail. A new cell that ships at partial state of charge delivers a lower resting voltage, which the transmitter reads as reduced headroom. The result is a shorter effective range that can look like a faulty battery or a pairing fault. Charge the parent unit fully before testing range — the cell needs to reach 4.2V at full charge for the transmitter to operate at rated power.
