It replaces OEM part numbers FPCBP149AP, FPCBP147, FPCBP149, FMVNBP153, FPCBP147AP, FMVNBP151, S26391-F340-L250, and S26391-F340-L200. Install it when the original cell no longer holds a usable charge or the system refuses to run off battery power at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQ-series platform fit:\u003c\/strong\u003e\n    The FMV-Q8230, Q8220, and LifeBook Q2010 share the same 10.8V three-cell rail, connector pinout, and BMS handshake protocol. One cell covers all of them. Swapping between these models does not require any firmware change or connector adapter.\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 Q-series hardware. The BMS accepted the charge handshake on first contact, balanced across all three cells without thermal event, and reported state-of-charge correctly to the OS by the second full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on the Q2010:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff on a normal workload — do not force-shutdown — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle. Skipping it leaves a false \"poor health\" warning in the system tray that does not reflect actual cell condition.\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-Q8230 BIOS flags a new battery as poor health on first boot\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Q8230 BIOS reads EEPROM data written by the original factory cell to establish its health baseline. A new cell arrives with different EEPROM values — the BIOS compares them against the old record and flags the mismatch as degraded health. This is a data comparison error, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by a complete uninterrupted charge cycle overwrites the stored baseline and clears the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLifeBook Q2010 shutting down at 20–30% battery shown\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 OS reads a percentage based on the old cell's curve, so 20% displayed may already be below the voltage the cell can sustain under combined CPU and display load. The cell hits its low-voltage cutoff before the OS reaches its shutdown threshold, causing an abrupt power-off. Run two full discharge-to-hibernate and full-recharge cycles — after the second cycle the fuel gauge recalibrates and the shutdowns stop. Target a resting voltage of 10.8V at full charge to confirm the cell is performing correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410846908506,"sku":"BWCS-FUQ2010HB-1","price":87.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410846941274,"sku":"BWCS-FUQ2010HB-2","price":103.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410846974042,"sku":"BWCS-FUQ2010HB-3","price":114.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUQ2010HB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-fmv-q8230-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
