It fits directly into the fixture housing and restores the backup power function that activates when mains power fails. Capacity is 4.8Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLQC 1 G EL N fit:\u003c\/strong\u003e\n    The LQC series uses a two-cell Ni-Cd pack at 2.4V with a specific footprint (44.50 × 24.80 × 22.70mm per cell). The charge controller in this fixture expects that voltage range on float — substituting a different chemistry or voltage causes the controller to flag a fault and refuse to complete the charge cycle.\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 charge and timed load discharge on the bench. The BMS accepted the cell without fault indication, and the charge LED transitioned from red to green within the expected window after a full 24-hour charge.\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 current and lets the charge controller register the new cell capacity before the fixture's 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\"\u003eEmergency light failing its duration test after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Ni-Cd cell rarely delivers its full rated capacity on the first discharge. Ni-Cd chemistry requires one or two full charge-discharge cycles before the cell reaches its rated 2000mAh. If the fixture is tested immediately after installation without a full 24-hour charge, the cell will exhaust early and the unit will fail its duration requirement. Allow a minimum 24-hour charge from a fully depleted state before running a compliance test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator staying red after confirmed good installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA cell that has sat in storage will have a resting voltage below the float acceptance window the LQC charge controller expects. When the controller measures that low voltage on connection, it can flag a fault rather than begin charging. Leave the unit plugged into mains for at least 12 hours — the trickle current will bring the cell voltage up into the acceptance range and the LED should transition to green. If it does not clear after 24 hours, check the connector seating and confirm no cell polarity reversal during installation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360406339674,"sku":"BWCS-EMC412LS-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360406372442,"sku":"BWCS-EMC412LS-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360406405210,"sku":"BWCS-EMC412LS-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EMC412LS-1.webp?v=1778614597","url":"https:\/\/batteryweb.com\/products\/lithonia-lqc-1-g-el-n-replacement-battery-24v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
