It slots into the battery compartment in place of the original NEB-NiCAD4 or NEB-NICAD8 cell. When mains power fails, this cell powers the LED array and keeps the fixture live for the full rated test duration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNE-602LED and NE-612LED shared cell:\u003c\/strong\u003e\n    Both fixtures use the same 3.6V single-cell bay, charge controller circuit, and connector pinout — one battery fits both. The charge controller monitors cell voltage at float, so the replacement cell must match the 3.6V nominal rating exactly.\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 simulated mains-loss cycle on the NE-602LED. The charge controller accepted the cell without fault, the LED array activated immediately on mains removal, and the BMS held discharge within spec across the full test 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 lets the charge controller register the new cell's capacity and confirm load acceptance before any scheduled compliance inspection. Skipping this step can cause the fixture to underperform on a formal duration 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 new battery installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe NE-602LED and NE-612LED charge controllers use cell voltage to decide whether to switch from bulk charge to float. A new Ni-MH cell shipped from storage may present a resting voltage low enough that the controller stays in fault or extended-charge mode, holding the red LED on. This is not a faulty battery or a faulty fitting. Allow 12–24 hours of uninterrupted mains power for the controller to bring the cell up to its float threshold, typically around 4.1–4.3V for a 3.6V Ni-MH cell. If the indicator is still red after 24 hours, check that the connector is fully seated and pins are making clean contact.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims or cuts short during a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the fixture dims noticeably partway through a test cycle, the cell has not yet reached its rated 2000mAh capacity — this happens on the first one or two discharge cycles after a period of storage. Ni-MH cells lose capacity through self-discharge during storage and recover it across several full charge-discharge cycles. Run one complete manual test cycle, then return the fixture to mains charge for a full 24 hours before re-testing. After that conditioning cycle, cell output should hold steady across the full test duration at 3.6V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360406667354,"sku":"BWCS-EMC612LS-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360406700122,"sku":"BWCS-EMC612LS-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360406732890,"sku":"BWCS-EMC612LS-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EMC612LS-1.webp?v=1778614597","url":"https:\/\/batteryweb.com\/products\/nora-lighting-ne-602led-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
