It replaces OEM part numbers FPCBP42, 0643970, and FM-33. The battery slots into any chassis that accepts the original FPCBP42 cell pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFMV-BIBLO NB and FMV-7xx series compatibility:\u003c\/strong\u003e\n    These models share the same 10.8V three-cell rail, identical connector pitch, and the same BMS handshake protocol — which is why one cell pack covers all of them 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 full charge and discharge cycles on a FMV-BIBLO NB-series unit. The BMS communicated correctly with the BIOS, reported accurate state-of-charge, and held the rated voltage without tripping thermal cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on FMV LifeBook units:\u003c\/strong\u003e\n    After fitting this battery, 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 every cell swap on these Fujitsu models.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the FMV-716NU3\/B BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe FMV LifeBook BIOS stores charge history and health data tied to the old cell's EEPROM signature. When a new cell installs, that stored data no longer matches the actual chemistry, so the BIOS flags it as degraded. This is not a fault with the replacement cell — it is a calibration mismatch. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the BIOS enough data to rewrite its health record. After one or two complete cycles, the health warning clears and the reported capacity aligns to the actual 36.72Wh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's discharge curve. The IC inherited voltage-to-percentage mapping from the old, degraded cell — so it miscalculates the remaining capacity and triggers shutdown before the cell is actually empty. It is not a defective battery. Run two or three full discharge-to-hibernate and full-recharge cycles without interruption. After calibration, the gauge will track accurately and the early shutdowns will stop — the cell sustains voltage above the 9.5V cutoff under combined CPU and display load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410846351450,"sku":"BWCS-FUC7600NB-1","price":61.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410846384218,"sku":"BWCS-FUC7600NB-2","price":72.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410846416986,"sku":"BWCS-FUC7600NB-3","price":80.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUC7600NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-fmv-716nu3b-replacement-battery-108v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
