It replaces OEM part numbers FPCBP373 and FMVNBP222. The connector, cell count, and BMS handshake match the original Fujitsu specification for these three models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT732, T734, and T902 compatibility:\u003c\/strong\u003e\n    All three models share the same 10.8V three-cell-series architecture, identical battery bay dimensions, and the same BMS communication protocol over the SMBus line. One cell fits all three 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 LifeBook T732. The BMS reported correct voltage at each stage, charge termination triggered at the expected 12.6V ceiling, and the SMBus handshake returned accurate state-of-charge data to the OS.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the T732\/T734\/T902:\u003c\/strong\u003e\n    After fitting this cell, run a full discharge until the laptop hibernates, then charge uninterrupted to 100% without using the machine. This forces the BIOS battery learn cycle to reset against the new cell's capacity curve and clears the false low-health warning that appears after any cell swap on these models.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LifeBook BIOS stores battery health data in EEPROM and compares it against the previous cell's charge history on every boot. A brand-new cell has no stored cycle data, so the BIOS flags it as degraded — the reading is wrong, not the hardware. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle. After two to three full cycles, the BIOS health indicator should resolve to a normal reading.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down with 20–30% charge still showing on screen\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 actual voltage curve. Under combined CPU and display load, voltage drops faster than the uncalibrated gauge predicts, and the BMS trips the low-voltage cutoff before the displayed percentage reaches zero. It is not a fault with the cell. Run two full discharge-to-hibernate cycles and the fuel gauge IC will map the new cell's voltage profile accurately. After calibration, the cutoff should align with a display reading below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409707565146,"sku":"BWCS-FUT732NB-1","price":143.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409707597914,"sku":"BWCS-FUT732NB-2","price":166.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409707630682,"sku":"BWCS-FUT732NB-3","price":183.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUT732NB-1.webp?v=1779580500","url":"https:\/\/batteryweb.com\/products\/fujitsu-lifebook-t732-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
