It restores full function to emergency exit signs and backup lighting systems that have lost capacity due to cell degradation. Voltage and capacity match the original cell exactly — 6V, 2000mAh (12Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e850.0014 fitting compatibility:\u003c\/strong\u003e\n    The 850.0014 uses a dedicated charge controller tuned to Ni-CD float voltage. This cell matches the required 6V nominal rail and the charge acceptance curve that controller expects — a lithium or NiMH substitute would cause incorrect charge termination and potential overcharge damage.\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 charge cycle and load test on the 850.0014 platform. The charge controller accepted the cell without fault, current draw tracked within spec, and the BMS registered full capacity before cutoff.\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 forces a genuine load cycle, lets the charge controller register the new cell, and confirms the battery can sustain output before your next scheduled compliance inspection.\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\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Ni-CD cell ships in a partially discharged state after months in storage. The 850.0014 charge controller tops the cell up on float charge, but one float cycle alone rarely brings the cell to full rated capacity. Without a deliberate load cycle, the cell cannot deliver its full 2000mAh during a timed duration test. Run a manual test within 24 hours of installation — a full discharge and recharge conditions the cell and allows rated capacity to develop properly.\u003c\/p\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\"\u003eThe 850.0014 charge controller checks cell voltage before accepting a new battery into its float window. A cell that has sat in storage can drop below the controller's minimum acceptance threshold, which holds the fault or charging LED on red. Leave the fitting powered for 12–24 hours — the controller trickle-charges the cell until voltage climbs into the acceptance window, then transitions to green. If the LED remains red beyond 24 hours, measure across the battery terminals; voltage should read above 5.4V at that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360313016410,"sku":"BWCS-KUF814LS-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360313049178,"sku":"BWCS-KUF814LS-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360313081946,"sku":"BWCS-KUF814LS-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KUF814LS-1.webp?v=1778611090","url":"https:\/\/batteryweb.com\/products\/kaufel-8500014-replacement-battery-6v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
