Philips SBC-EB4880 Replacement Battery 4.8V 700mAh

Philips SBC-EB4880 / Avent SCD 468/84-R — 4.8V Ni-MH Replacement Battery (MT700D04CX51)

This 4.8V 700mAh Ni-MH battery replaces the OEM pack in the Philips SBC-EB4880 A1507 and Avent SCD 468/84-R baby monitor parent units. It restores cordless operation to the handset so you can move freely while monitoring. Voltage and cell count match the original factory specification exactly.

• SBC-EB4880 and SCD 468/84-R compatibility: Both parent units share the same four-cell Ni-MH pack configuration, the same connector pinout, and the same BMS charge-termination logic — so one replacement covers both models without modification.
• Bench tested on actual hardware: We cycled this pack on the SBC-EB4880 parent unit and confirmed the BMS accepted charge cleanly, terminated at the correct delta-V peak, and handed off to trickle without fault flags.
• Re-pair after fitting: Baby monitor parent units lose their wireless link whenever the handset goes completely dead. After fitting this battery and charging, hold the parent unit's link button until the camera unit acknowledges — the monitor will not reconnect on its own.

Why the SBC-EB4880 parent unit drops its camera link after a battery swap

The parent unit stores its paired camera address in volatile memory backed by the battery. When the pack voltage drops to zero during a swap, that memory clears and the radio module loses its registered channel. The camera unit is still broadcasting, but the parent unit has no address to lock onto. A manual re-pair — typically a five-second button hold on both units — writes the address back and restores the link immediately.

Parent unit battery draining overnight with screen staying on

Running the LCD backlight continuously through the night is a sustained current draw that a 700mAh cell was not sized to absorb for eight-plus hours in isolation. Most users report the drain after disabling the screen-timeout function, which is off by default on some firmware versions. Go into the display settings menu and set the screen timeout to 30 seconds or less. That one change alone brings overnight current draw back within the battery's cycle budget.
