It fits the FMV-7180MR3, LifeBook E7010, LifeBook E2010, FMV-BIBLO MR16B, and seven additional models in the same series. OEM cross-references are FM-36, FPCBP59AP, and FPCBP59.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFMV \/ LifeBook E-series platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, physical connector pinout, and BMS handshake protocol — which is why a single cell covers the full range. The battery communicates charge state and health data over the same SMBus line across all listed variants.\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 a LifeBook E-series unit. The BMS handshake completed on first insertion, the BIOS recognised the pack without prompting a fault code, and the charge circuit cycled correctly from depleted to full.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install cycle on Fujitsu notebooks:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it hibernates from low charge — do not interrupt. 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\"\u003eWhy the FMV-7180MR3 shuts down at 20–30% charge remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS fuel gauge IC on this platform maps voltage curves against data stored from the original cell. A new cell with a slightly different discharge curve hits a voltage threshold the firmware interprets as critically low — even though charge physically remains. The laptop cuts power before the cell is actually depleted. Running two full discharge-to-hibernate and uninterrupted-recharge cycles recalibrates the fuel gauge against the new cell's actual voltage curve. After calibration, the shutdown point drops back to the correct low-charge threshold, typically below 5%.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting 0% or \"poor health\" immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the BIOS reads health data from EEPROM registers on the battery pack — and the new cell's EEPROM values do not match the wear history the firmware was tracking on the old pack. The system flags the mismatch as a fault rather than a fresh cell. It is not a hardware fault with the replacement battery. Boot into the Fujitsu battery utility or run a full discharge-and-recharge cycle to prompt the BIOS to write new baseline data to its registers, clearing the warning.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410846646362,"sku":"BWCS-FUE2010NB-1","price":74.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410846679130,"sku":"BWCS-FUE2010NB-2","price":87.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410846711898,"sku":"BWCS-FUE2010NB-3","price":97.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUE2010NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-fmv-7180mr3-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
