These fittings power exit signs and evacuation lighting when mains supply fails. Swap this cell when the original no longer holds charge or the fitting flags a battery fault.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE1875-01-00 \/ E82082100 \/ ENB06006 compatibility:\u003c\/strong\u003e\n    All three models run the same 6V battery rail with matching connector pinout and physical footprint — 52.38 × 43.46 × 27.20mm. The charge controller in each fitting expects a Ni-MH cell at this voltage; swapping in a different chemistry will cause false fault signals or overcharge damage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full mains-failure simulation. The BMS accepted charge normally, the float voltage settled within spec, and the fitting cleared its fault LED after one complete charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle test requirement:\u003c\/strong\u003e\n    Within 24 hours of installation, hold the test button for the full rated duration. A cell shipped from storage will not yet be at rated capacity — this forced discharge-recharge cycle lets the charge controller register the new cell and prevents a false fail on the 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 new battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA cell in storage self-discharges, and by the time it arrives the resting voltage may sit below the charge controller's float acceptance window. Some Prescolite fittings interpret this low entry voltage as a fault rather than a depleted cell, so the red LED stays on even after correct installation. Leave the fitting on mains power for a full 24-hour charge cycle before judging the indicator. If the LED has not shifted to green after 24 hours, measure the cell voltage directly — a healthy Ni-MH cell at 6V nominal should read at least 6.0V fully charged under no load.\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 its first full conditioning charge before the test is triggered. A partially charged Ni-MH cell delivers full brightness briefly, then sags as internal resistance limits current delivery. The fitting reads this as low battery and dims or cuts off early — this is not a faulty cell. Allow the full 24-hour initial charge, then re-run the test. The cell should then sustain full output through the rated duration without dimming.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360425410650,"sku":"BWCS-EMC600LS-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360425443418,"sku":"BWCS-EMC600LS-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360425476186,"sku":"BWCS-EMC600LS-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EMC600LS-1.webp?v=1778614638","url":"https:\/\/batteryweb.com\/products\/prescolite-e1875-01-00-replacement-battery-6v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
