It fits models 002095, 002072, 002233, and 002265. These fittings use this pack to power maintained and non-maintained emergency lighting during mains failure events.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKaufel 002095 \/ 002072 \/ 002233 \/ 002265 compatibility:\u003c\/strong\u003e\n    All four models run the same 24V charge rail and use an identical connector and cell format. The charge controller in each fitting expects a Ni-CD pack at this voltage — substituting a different chemistry here will trigger a permanent fault state on the charge board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge cycle and simulated mains dropout. The BMS accepted float charge without fault, and the cell voltage held above the low-voltage cutoff threshold across the full discharge test period.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst test cycle after installation:\u003c\/strong\u003e\n    Within 24 hours of fitting the new cell, hold the test button for the full rated duration. This lets the charge controller register actual cell capacity before the next scheduled compliance test — a new Ni-CD pack from storage may not reach full rated output on its very first activation without this conditioning cycle.\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\"\u003eKaufel fittings monitor incoming cell voltage at the start of the charge cycle. A pack that has been in storage can sit below the float acceptance window — typically under 22V for a 24V Ni-CD — and the controller reads this as a fault rather than a discharged cell. The charge board then holds the red LED and does not begin charging. Leave the fitting powered for up to 12 hours; most controllers will begin trickle-charging once the cell voltage creeps above the acceptance threshold, after which the indicator shifts to amber and then green. If the LED remains red past 12 hours, measure pack voltage directly — a healthy new cell should be reading at least 20V after that window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light failing its duration test after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Ni-CD pack has not yet completed a full charge-discharge cycle, so rated capacity is not available on the first activation. During a duration compliance test this shows as the light cutting out before the required period ends — not a faulty cell, but an unconditioned one. Run one full manual test cycle immediately after installation: charge for 24 hours, then hold the test button through the complete rated duration. Capacity typically reaches specification by the second or third cycle. Do not schedule a formal compliance test until at least one full conditioning cycle is complete.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360323436634,"sku":"BWCS-KUF265LS-1","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360323469402,"sku":"BWCS-KUF265LS-2","price":152.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360323502170,"sku":"BWCS-KUF265LS-3","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KUF265LS-1.webp?v=1778611090","url":"https:\/\/batteryweb.com\/products\/kaufel-002095-replacement-battery-24v-4000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
