It fits models 002262, 002015, 002132, and 002255. The pack slots into the fitting and connects to the onboard charge controller that keeps the cell topped up from the mains supply.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e002262, 002015, 002132, and 002255 compatibility:\u003c\/strong\u003e\n    These four Kaufel units share the same 12V charging circuit, connector pinout, and physical bay dimensions — 163.30 x 65.50 x 60.50mm — so a single cell type covers all four without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a simulated mains-failure cycle. The BMS accepted the load without a fault trip, and voltage held steady across the full discharge arc required for emergency duration compliance.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst test cycle after installation:\u003c\/strong\u003e\n    Hold the test button for the full rated duration within 24 hours of fitting. This lets the charge controller register actual cell capacity before your next scheduled compliance test — skipping this step means the controller may flag a fault based on stale data from the old pack.\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 partial state of charge after months in storage. The Kaufel charge controller needs at least one full charge-then-discharge cycle before the cell reaches its rated 4000mAh capacity. If you run a compliance test before that conditioning cycle completes, the light will cut out early — not because the battery is faulty, but because the cell hasn't yet reached full electrochemical capacity. Charge the unit on mains for 24 hours, then run a full manual test to confirm the pack sustains load at or above 10.5V before your inspector arrives.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator staying red after a confirmed good installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSome Kaufel fittings latch a fault condition in firmware and won't clear it automatically when a new cell is fitted. The red LED persists because the controller logged an undervoltage event from the old depleted pack and hasn't reset its fault register. On most 002262-series units, disconnecting mains power for 30 seconds, then reconnecting, forces a controller reset and clears the latched fault. If the LED stays red after that, check that the cell resting voltage is above 11.0V — a cell below that threshold sits outside the float acceptance window and the controller will refuse to begin charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360324517978,"sku":"BWCS-KUF255LS-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360324550746,"sku":"BWCS-KUF255LS-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360324583514,"sku":"BWCS-KUF255LS-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KUF255LS-1.webp?v=1778611090","url":"https:\/\/batteryweb.com\/products\/kaufel-002262-replacement-battery-12v-4000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
