It uses OEM part numbers FPCBP105 and FPCBP105AP. Physical dimensions are 192.50 x 102.25 x 20.70mm — confirm these match your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN6010 \/ N6200 \/ N6210 \/ N6220 compatibility:\u003c\/strong\u003e\n    All four LifeBook models in this series share the same 14.8V battery rail, connector pinout, and BMS handshake protocol, which is why a single cell covers the entire N6000 range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an N6220 chassis. The BMS negotiated correctly with the host, charge termination triggered at full capacity, and the protection circuit tripped cleanly at low-voltage cutoff without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for the N6010 \/ N6220:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells in these LifeBook models.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLifeBook N6220 shutting down at 20–30% charge shown\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the N6220 runs under full CPU and display load, the cell must sustain voltage above the BIOS low-voltage cutoff threshold. An aged or uncalibrated cell hits a voltage cliff — the terminal voltage drops sharply under load even though the fuel gauge still reads 20–30%. The BIOS interprets this voltage drop as a fault and cuts power immediately. Completing one full calibration cycle — full discharge to hibernate, then a full uninterrupted charge — lets the fuel gauge IC re-map the new cell's actual voltage curve and eliminates premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS showing battery health as \"poor\" or \"unknown\" after fitting this cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LifeBook BIOS reads health data from EEPROM registers on the battery's BMS board. When a new cell is installed, the EEPROM presents fresh cycle-count and state-of-health values that do not match the data the BIOS cached from the previous cell — this mismatch triggers the health warning. It is not a fault with the replacement cell. Run the full discharge-to-hibernate then charge-to-100% learn cycle once, and the BIOS will write new baseline data, clearing the warning. After that first cycle, the health indicator should read normal at 14.8V full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410841960538,"sku":"BWCS-FU6220NB-1","price":63.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410841993306,"sku":"BWCS-FU6220NB-2","price":74.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410842026074,"sku":"BWCS-FU6220NB-3","price":82.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU6220NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-lifebook-n6010-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
