It fits the SBC-SC477, SBC-SC466, SBC-SC487, and SBC-S477 among others. When the original cell can no longer hold a charge, the parent unit loses cordless operation and drops its wireless link to the camera base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSBC-SC466 \/ SC477 \/ SC487 parent unit compatibility:\u003c\/strong\u003e\n    These handsets share the same 2.4V two-cell Ni-MH pack, connector orientation, and BMS handshake with the charging cradle. Swapping to a mismatched voltage will prevent the cradle from completing a full charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through cradle charging and confirmed the BMS accepted the charge cycle without fault. Voltage at full charge measured within the expected Ni-MH ceiling for a 2-cell pack, and the handset powered on cleanly from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pair after installation:\u003c\/strong\u003e\n    After fitting a new battery, place the parent unit back in the charging cradle before attempting to reconnect to the base station. A fully depleted handset loses its wireless pairing state — the cradle charge restores the voltage level the radio module needs to re-initialise the link.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit not connecting to camera unit after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePhilips baby phone parent units store their pairing data in volatile memory that clears when the handset drops below a critical voltage threshold. A brand-new Ni-MH cell ships partially discharged, so the radio module may not have enough voltage to re-establish the wireless link immediately after installation. Place the parent unit in its charging cradle for a full charge cycle before attempting to pair. Once fully charged, hold the pairing button on the base station until the handset confirms the link — typically indicated by a stable signal icon on the parent unit screen.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit battery draining completely overnight\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRunning the parent unit with the LCD screen active all night is a sustained draw that Ni-MH cells at 1200mAh were not sized to sustain indefinitely. The screen backlight and IR receiver together pull significantly more current than the radio link alone. Enable the screen timeout in the monitor's display settings so the LCD blanks after a short idle period while audio and alert monitoring continues. If the unit still won't last a full night after enabling screen timeout, check that the charging cradle contacts are clean — oxidised contacts on Ni-MH cradles reduce charge acceptance and the cell may not be reaching a true full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315074465882,"sku":"BWCS-PHC466MB-1","price":21.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43315074498650,"sku":"BWCS-PHC466MB-2","price":24.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43315074531418,"sku":"BWCS-PHC466MB-3","price":26.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHC466MB-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/philips-sbc-sc477-replacement-battery-24v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
