It powers the fitting's backup illumination during mains failure events. Voltage and capacity match the original spec exactly — 6V, 2000mAh, 12Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKaufel 850.0061 fitting compatibility:\u003c\/strong\u003e\n    The 850.0061 fitting uses a dedicated charge controller calibrated for a 6V Ni-MH cell at this capacity. Swapping chemistry or voltage causes the controller to misread charge state and flag a fault. This cell keeps the charge rail at the voltage the controller expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and timed discharge on the 850.0061 fitting. The BMS accepted the cell without fault codes, and the charge indicator moved from red to green within the expected window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle activation on Kaufel fittings:\u003c\/strong\u003e\n    After fitting, hold the test button for the full rated duration within 24 hours of installation. This lets the charge controller register actual cell capacity and clears any residual fault state from storage voltage before your 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 fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells lose voltage during storage. If a cell ships at low resting voltage, the Kaufel 850.0061 charge controller sits outside its float acceptance window and holds the fault LED red rather than beginning a normal charge cycle. This is not a faulty cell — it is a voltage threshold condition. Leave the fitting on mains power for 12 to 24 hours; the controller will detect rising cell voltage and transition to normal charge mode. If the LED has not shifted to green after 24 hours, confirm mains supply to the fitting is live and the cell connector is fully seated.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light fails its duration test after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed cell has not yet completed a full charge cycle, so its usable capacity at the point of a duration test is lower than rated. The fitting dims or cuts out before the test period ends — this is not a defective cell. Run one full manual test cycle immediately after installation: charge for a minimum of 24 hours, then hold the test button through the complete rated duration. That single cycle conditions the cell and allows the controller to record accurate capacity data ahead of any formal compliance inspection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360347455578,"sku":"BWCS-KAF850FT-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360347488346,"sku":"BWCS-KAF850FT-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360347521114,"sku":"BWCS-KAF850FT-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KAF850FT-1.webp?v=1778611089","url":"https:\/\/batteryweb.com\/products\/kaufel-8500061-replacement-battery-6v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
