It replaces OEM part numbers FPCBP80 and FPCBP80AP. The connector and BMS handshake match the original Fujitsu spec so the pack seats and communicates correctly without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS6200 series platform fit:\u003c\/strong\u003e\n    These Lifebook models share the same 10.8V three-cell rail, identical battery bay dimensions (131.10 × 79.40 × 20.20mm), and the same EC communication protocol. One battery works across all listed variants because Fujitsu used the same power system throughout the S6200 chassis generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on an S6200 chassis. The BMS negotiated correctly with the embedded controller, charge acceptance reached full capacity without cutoff errors, and the pack held voltage within spec across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on the Lifebook S6200:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it drops to hibernate-cutoff — do not interrupt — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the Lifebook EC triggers after every 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 installing a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Fujitsu Lifebook EC reads health data from the battery's EEPROM during every boot. When a new cell arrives, its EEPROM charge history doesn't match what the EC expects from the previous pack, so it flags health as poor or unknown before any actual degradation has occurred. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate followed by an uninterrupted charge to 100% — the EC rewrites its learn table and the health flag clears. If the warning persists after two full cycles, check the EC firmware version in the BIOS utility.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLifebook S6200 shutting down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot sustain voltage under combined CPU and display load — the voltage drops below the EC's cutoff threshold before the fuel gauge IC reaches 0%. The fuel gauge IC on these Lifebook models calibrates against the cell's actual discharge curve, and a new cell needs two to three full cycles before that curve is accurately mapped. Until calibration is complete, the reported percentage and the real voltage cliff won't align. Run two full discharge-to-hibernate cycles and the shutdowns will stop as the gauge IC locks onto the correct curve, typically resolving by the time the cell holds steady above 10.0V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410840780890,"sku":"BWCS-FU6200NB-1","price":53.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410840813658,"sku":"BWCS-FU6200NB-2","price":63.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410840846426,"sku":"BWCS-FU6200NB-3","price":69.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FU6200NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/fujitsu-lifebook-s6200-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
