It matches the original voltage rail and connector spec across all listed variants. OEM part numbers covered include FMVTBBP101, FPCBP123, FPCBP63, FPCBP67, FPCBP77, FPCBP97, and their AP-suffix equivalents.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eST4000P and ST4100-series compatibility:\u003c\/strong\u003e\n    These tablets share a common 11.1V three-cell architecture with the same physical connector and BMS handshake protocol. One cell pack covers the full range — the BMS communicates identically across FMVTBBP101 through FMVTBBP107 and the FPCBP-series equivalents.\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 the ST4000P platform. The BMS accepted the new cell without errors, charge termination triggered correctly at capacity, and no overcurrent flags appeared during the test sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap recalibration on the ST4000P:\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 or capacity warning that appears after every cell replacement on this platform.\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 Stylistic ST4000P BIOS reads health data stored in the battery's EEPROM, not from live cell measurements. When a new cell is installed, that EEPROM carries different cycle count and rated Wh data than what the BIOS expects. The system flags this mismatch as poor health or unknown battery — the cell itself is fine. Run a full battery learn cycle (full discharge to hibernate, then uninterrupted charge to 100%) and the BIOS recalculates health against the new cell's actual data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStylistic tablet shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff failure — the fuel gauge IC still shows remaining charge, but the cell voltage drops below the minimum threshold under combined CPU and display load before the percentage reaches zero. It happens most often after a few cycles on a freshly installed cell because the fuel gauge IC hasn't calibrated against the new chemistry yet. The fix is two to three full discharge-to-cutoff and full-recharge cycles so the gauge IC maps the actual voltage curve. After calibration, shutdowns at 20–30% stop, and the fuel gauge tracks accurately down to the BIOS cutoff voltage of approximately 9.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410840551514,"sku":"BWCS-FU4110HB-1","price":68.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410840584282,"sku":"BWCS-FU4110HB-2","price":81.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410840617050,"sku":"BWCS-FU4110HB-3","price":90.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU4110HB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-stylistic-st4000p-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
