Philips SBC-SC463 Replacement Battery 4.8V 2000mAh

Philips SBC-SC463 / SBC-SC465 / SBC-SC467 / SBC-SC469 — 4.8V Ni-MH Replacement Battery (NA150D04C051)

This is a 4.8V 2000mAh Ni-MH replacement battery for the Philips SBC-SC463 series baby monitor parent unit. It fits the SBC-SC463, SBC-SC465, SBC-SC467, and SBC-SC469 handsets. When the original cell loses charge capacity, this swap restores full operation to the parent unit.

• SBC-SC463 series parent unit compatibility: These four handsets share the same 4.8V four-cell Ni-MH pack, the same physical footprint (50.50 × 57.00 × 14.50mm), and the same OEM part number NA150D04C051 — so one replacement covers the entire range.
• Bench tested on actual hardware: We cycled this pack through the SBC-SC463 charge circuit and confirmed the BMS accepted a full charge without interruption and that cell voltage balanced correctly across all four cells before sign-off.
• Re-pair the wireless link after installation: Philips SBC-SC4xx parent units drop their wireless pairing with the nursery receiver whenever the battery is fully removed. After fitting this battery, power both units on and run the pairing sequence from the parent unit menu before relying on the monitor.

Parent unit not connecting to the nursery receiver after battery swap

The SBC-SC4xx stores its wireless channel and pairing data in volatile memory backed by the battery. A full battery removal clears that memory, so the parent unit comes back up without a registered receiver. This is not a fault with the replacement battery — it is a predictable result of power interruption. Power on both the parent unit and the nursery receiver, then hold the pairing button on the parent unit until the link indicator confirms a connection. The nursery receiver does not need to be reset separately.

Parent unit battery draining overnight with screen staying on

The SBC-SC4xx parent unit runs its LCD backlight continuously when screen timeout is disabled — this is the single largest drain on the 2000mAh pack during night-time use. A fresh Ni-MH cell at 4.8V will still deplete faster than expected if the screen stays lit for eight-plus hours. Go into the parent unit display settings and set the screen timeout to the shortest available interval — the audio alert still fires with the screen off. Check that the charge contact on the base station is clean and making solid contact; a dirty contact means the unit runs on battery even when docked.
