It fits the Kosnic KBAT1800 emergency lighting unit. The cell slots into the fitting and connects to the onboard charge controller that manages float charging between mains-on cycles.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKBAT1800 compatibility:\u003c\/strong\u003e\n    The KBAT1800 fitting uses a dedicated charge controller matched to LiFePO4 float voltage — typically 3.45V. Swapping to a different chemistry would take the controller out of its calibrated range and cause incorrect charge termination or fault flags.\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 discharge-to-cutoff cycle and confirmed the BMS held steady voltage output until depletion. The cell accepted the float charge without triggering the controller's overvoltage protection.\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 baseline before any scheduled compliance test runs against it.\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 LiFePO4 cell may not pass a full duration test immediately. The cell ships in a partial state of charge, and the charge controller needs one complete charge cycle to condition the cell to full capacity. Running a duration test before that cycle completes will produce a shorter output than the cell can actually deliver. Fit the battery, allow 24 hours of mains charging, then run the test — the cell should hold its rated output across the full test period.\u003c\/p\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\"\u003eSome KBAT1800 fittings will hold the red fault LED if the incoming cell voltage sits outside the controller's float acceptance window on first connection. A cell that has self-discharged during storage can present below the threshold the controller expects to see at rest. Leave the fitting on mains power for two to four hours — the controller should step through its conditioning routine and shift the indicator to green once the cell voltage rises into the accepted float range of around 3.3–3.45V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43306868015194,"sku":"BWCS-KKB180LS-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43306868047962,"sku":"BWCS-KKB180LS-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43306868080730,"sku":"BWCS-KKB180LS-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KKB180LS_1.webp?v=1777768837","url":"https:\/\/batteryweb.com\/products\/kosnic-kbat1800-replacement-battery-32v-1500mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
