It replaces OEM part HB00095TA. The battery powers the fitting during mains failure, supplying backup illumination for evacuation compliance.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e61884, 9342819 and H95400 compatibility:\u003c\/strong\u003e\n    All three models share the same 4.8V cell configuration, connector pinout, and charge controller circuit. A single replacement cell services all three without modification.\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 mains-failure simulation. The charge controller accepted the cell, float charge stabilised correctly, and the fitting switched to battery within the expected response window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst test cycle after installation:\u003c\/strong\u003e\n    Within 24 hours of fitting the new cell, hold the test button for the full rated test duration. This lets the charge controller register the new cell's capacity and confirms the cell accepts a load — critical before any 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\"\u003eCharge indicator staying red after new battery installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-CD cells shipped from storage often sit at a lower resting voltage than the fitting's float acceptance window expects. When the controller sees an unfamiliar voltage on the terminals, it holds the fault or charge state rather than switching to green. This is not a faulty cell. Leave the fitting on mains power for 24 hours — the controller will complete its charge cycle and the indicator should move to green once the cell reaches approximately 5.4–5.6V fully charged across the four cells.\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\"\u003eA cell that has not completed one full conditioning cycle will not deliver its rated 2000mAh on the first discharge. The output voltage drops below the fitting's low-voltage cutoff sooner than expected, and the light dims or cuts out before the test duration ends. The fix is a 24-hour full charge before the test, followed by one complete discharge cycle. After one full charge-discharge cycle, the cell reaches rated capacity and the fitting will sustain output for the full duration.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360397164634,"sku":"BWCS-LGH954LS-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360397197402,"sku":"BWCS-LGH954LS-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360397230170,"sku":"BWCS-LGH954LS-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LGH954LS-1.webp?v=1778611164","url":"https:\/\/batteryweb.com\/products\/legrand-61884-replacement-battery-48v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
