It replaces OEM part numbers FPCBP49, FPCBP50, FMVLBP103, and FMVLBP104. Use it when the original cell has degraded and the laptop can no longer hold a charge away from the wall.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLifeBook and LOOX T-series compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell rail, physical connector pinout, and BMS handshake protocol. A single replacement cell covers the full group 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 charge and discharge cycles on the P2110 platform. The BMS accepted the handshake immediately, the protection circuit engaged correctly at low-voltage cutoff, and the fuel gauge IC updated without error across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on LifeBook:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it hibernates at low charge, 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 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 battery health as poor after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LifeBook BIOS stores capacity data from the previous cell in its battery learn table. When a new cell arrives with different EEPROM values, the BIOS compares them against the stored baseline and flags the battery as degraded. This is a firmware read mismatch, not a cell fault. Run one full discharge-to-hibernate cycle followed by an uninterrupted full charge — the BIOS relearns the new cell's profile and clears the warning on the next boot.\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 actual voltage curve. The gauge inherits calibration data from the old, degraded cell and misreads the new cell's state of charge. Under combined CPU and display load, voltage drops faster than the gauge anticipates, and the system hits the hardware cutoff before the displayed percentage reaches zero. Complete two full discharge-to-cutoff and charge-to-100% cycles — after that, the fuel gauge IC recalibrates and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410840682586,"sku":"BWCS-FU2110HB-1","price":68.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410840715354,"sku":"BWCS-FU2110HB-2","price":81.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410840748122,"sku":"BWCS-FU2110HB-3","price":90.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU2110HB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-fmv-lifebook-270ls-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
