It replaces OEM part 40000009 and restores the unit's ability to activate backup illumination during a mains failure. Capacity is 14.4Wh — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePCF14004 compatibility:\u003c\/strong\u003e\n    The PCF14004 uses a dedicated charge controller tuned to Ni-CD float voltage. This cell matches the original 3.6V nominal rating, so the controller charges at the correct rate without triggering a fault state or overcharging the cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge cycle and simulated mains-failure activation. The charge controller reached float stage without fault, and the cell voltage held above the BMS low-voltage cutoff threshold throughout the load test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the PCF14004:\u003c\/strong\u003e\n    After installation, hold the test button for the unit's full rated test duration within 24 hours. This lets the charge controller register the new cell capacity and prevents a false fail on your next scheduled compliance test.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator staying red after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PCF14004's charge controller checks incoming cell voltage before accepting it into the float charge window. A new Ni-CD cell that has sat in storage can arrive with a resting voltage low enough to sit outside that acceptance range. The controller interprets this as a fault and holds the red indicator rather than switching to green. Leave the unit on mains for 24–48 hours — the trickle charge stage will bring the cell up to a voltage the controller accepts, typically above 3.4V resting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims partway through a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDimming during a test run points to the cell not yet holding its full 4000mAh charge on the first activation. A freshly installed Ni-CD cell needs at least one complete charge-discharge cycle before it reaches rated capacity — this is normal cell behaviour, not a fault. Run the unit on mains charge for a full 24 hours before performing the duration test. If dimming persists after a second full charge cycle, check the cell connection contacts for oxidation and confirm terminal voltage under load stays above 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360313901146,"sku":"BWCS-PBF140LS-1","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360313933914,"sku":"BWCS-PBF140LS-2","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360313966682,"sku":"BWCS-PBF140LS-3","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PBF140LS-1.webp?v=1778611108","url":"https:\/\/batteryweb.com\/products\/philips-bodine-pcf14004-replacement-battery-36v-4000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
