It replaces OEM part numbers ELB 0701N, 60619-1, 61117-1, and 4PH22. When the original cell depletes or fails, this battery restores the unit's ability to power emergency illumination during a mains failure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLV S W R 120\/277 ELN UM compatibility:\u003c\/strong\u003e\n    These Lithonia units use a fixed 7.2V Ni-CD pack with a specific cell arrangement that matches the onboard charge controller's float voltage and current profile. Swapping chemistry or voltage breaks that match and prevents proper charge termination.\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 a load test on the LV S W R platform. The BMS accepted the cell, float charge engaged correctly, and the charge indicator advanced to green within the expected window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst test cycle after installation:\u003c\/strong\u003e\n    Within 24 hours of fitting, hold the test button for the full rated duration. This confirms the new cell accepts load under real conditions and allows the charge controller to register actual cell 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\"\u003eCharge indicator staying red after new battery installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Ni-CD cell that has sat in storage will often present a resting voltage below the charge controller's float acceptance window. The controller reads this as a fault condition and holds the red indicator rather than entering normal charge mode. The fix is to leave the unit on mains power undisturbed for a full 24-hour charge cycle. After that period, the cell voltage should reach at least 8.4V at rest, and the indicator should advance to green.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims and cuts short during a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell has not completed a full initial charge before the test is run. Ni-CD cells need one complete charge cycle to reach rated capacity — a partially charged cell will hit the low-voltage cutoff early and drop output. If the unit dimmed during test, put it back on mains for 24 hours before retesting. A cell that still dims after a full charge cycle has likely developed memory effect or internal resistance damage and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360404602970,"sku":"BWCS-EMC701LS-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360404635738,"sku":"BWCS-EMC701LS-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360404668506,"sku":"BWCS-EMC701LS-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EMC701LS-1.webp?v=1778614597","url":"https:\/\/batteryweb.com\/products\/lithonia-lv-s-w-r-120277-eln-um-replacement-battery-72v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
