It fits the T50E, T50E\/W, T50G\/W, T55G, and over fifteen additional LOOX T-series models sharing the same connector and BMS handshake. OEM part numbers covered include FMVNBP117, FMVNBP118, FPCBP100, FPCBP68, FPCBP69, and several cross-references.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLOOX T-series platform fit:\u003c\/strong\u003e\n    These models share a common connector pinout, 10.8V nominal rail, and the same BMS communication protocol — the replacement cell negotiates with the LOOX T-series controller the same way the original did, 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 on the LOOX T-series platform. The BMS accepted the new cell, fuel gauge initialised correctly, and charge terminated cleanly at full capacity without false fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLOOX T-series BIOS recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run one complete discharge down to the hibernate cutoff — do not interrupt it — then charge uninterrupted to 100%. This lets the BIOS battery learn cycle reset against the new cell and clears the inaccurate health 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LOOX T-series BIOS stores charge history and health metrics in the original cell's EEPROM. When a new cell goes in, the BIOS compares live readings against the old EEPROM baseline and flags a mismatch as poor health. The battery itself is not faulty — the firmware simply hasn't learned the new cell's characteristics yet. Run one full discharge-to-hibernate cycle followed by a full uninterrupted charge. After two to three cycles, the BIOS health status recalibrates and the warning clears.\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 is still calibrated to the old, degraded cell. The old cell had a steep voltage cliff at low state-of-charge — the gauge learned to shut down early to protect it. The new cell holds voltage further into its discharge curve, but the IC doesn't know that yet. Force a full discharge to the hibernate cutoff, let the system sit for two minutes, then charge continuously to 100% — this recalibrates the fuel gauge IC against the new cell's actual voltage profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410841206874,"sku":"BWCS-FUT50NB-1","price":61.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410841239642,"sku":"BWCS-FUT50NB-2","price":72.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410841272410,"sku":"BWCS-FUT50NB-3","price":80.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUT50NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-fmv-biblo-loox-t50e-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
