It restores backup illumination capability in aged or degraded units. Cross-references include 40000021, 40000067, GP250CKT9TMX, BCN2500-9GWP-CE8981, and GP250CKT9TMXH.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEmergency lighting platform fit:\u003c\/strong\u003e\n    These OEM part numbers share the same 10.8V nine-cell Ni-CD configuration, connector orientation, and physical envelope — 146.50 x 47.70 x 47.70mm — allowing a direct mechanical and electrical swap within compatible Philips fittings without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell pack through charge acceptance and load discharge on a Philips emergency fitting. The charge controller recognised the cell within the float acceptance window, and the BMS did not flag a fault under rated load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle test requirement:\u003c\/strong\u003e\n    Within 24 hours of installation, hold the fitting's test button for the full rated duration. This confirms the new cell accepts load current and lets the charge controller register capacity before your next scheduled compliance inspection.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light failing its duration test after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-CD cells ship in a partial state of charge. When a freshly installed cell goes straight into a duration test, it cannot sustain full output because it has not completed an initial charge cycle. The fitting's charge controller needs a full uninterrupted charge period — typically 24 hours on mains — before the cell reaches rated capacity. Running the duration test before this period ends will produce a short-run result that reflects charge state, not cell defect. Allow a full 24-hour mains charge, then retest; the cell should hold load at or above 10.0V under discharge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator staying red after new battery installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSome Philips fittings use a float-voltage threshold to confirm a valid cell is connected before switching the charge LED to green. A replacement cell fresh from storage may sit below that acceptance window — typically around 9.6V to 10.0V resting — causing the controller to hold the fault or charging indication. This is not a wiring fault. Leave the fitting on mains power for at least four hours; the trickle charge will bring resting voltage into the acceptance range and the indicator should transition. If the LED remains red beyond 24 hours, check connector seating and confirm cell polarity at the connector.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360312328282,"sku":"BWCS-PBS722LS-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360312361050,"sku":"BWCS-PBS722LS-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360312393818,"sku":"BWCS-PBS722LS-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PBS722LS-1.webp?v=1778611108","url":"https:\/\/batteryweb.com\/products\/philips-replacement-battery-108v-3000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
