It matches the OEM voltage rail and connector footprint across all four models. Capacity is 56.16Wh — taken from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB8200 \/ B6000D \/ B6110D platform fit:\u003c\/strong\u003e\n    These four models share the same 7.2V two-cell configuration, identical connector pinout, and the same BMS communication protocol — which is why one pack 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 pack through full charge and load cycles on the B8200. The BMS negotiated correctly with the system controller, charge acceptance reached rated capacity, and no protection faults triggered under CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the B8200:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to complete against the new cell data and clears the inaccurate health warning that appears on every fresh cell swap.\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 the new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe B8200 BIOS reads health data from the EEPROM on the battery's BMS board, not from a live capacity measurement. When a new cell arrives with EEPROM values that don't match the system's stored history, the BIOS flags it as degraded before it has run a single cycle. This is not a fault with the replacement cell. Run one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% — after that cycle, the BIOS recalibrates against the actual cell and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLifeBook B8200 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold before the fuel gauge IC reaches zero — a voltage cliff under combined CPU and display load. The fuel gauge was calibrated against the old degraded cell and now reads the new cell inaccurately during the first few cycles. It is not a defective replacement. Complete two full discharge-to-hibernate then charge-to-100% cycles and the fuel gauge IC will recalibrate its voltage-to-percentage curve against the new cell chemistry. Unexpected shutoffs should stop once the gauge tracks the actual cell voltage floor, which sits at approximately 6.0V under load for this pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410842681434,"sku":"BWCS-FU8200NB-1","price":87.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410842714202,"sku":"BWCS-FU8200NB-2","price":103.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410842746970,"sku":"BWCS-FU8200NB-3","price":115.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU8200NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-fmv-lifebook-b8200-replacement-battery-72v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
