It carries a 5200mAh (56.16Wh) capacity and fits the SH782 chassis using the original connector and retention clip. OEM part numbers FPCBP390, FMVNBP224B, FMVNBP224, FPCBP391, FPCBP392, and FPB0290 all cross to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSH782 compatibility:\u003c\/strong\u003e\n    The SH782 shares its battery bay and BMS handshake protocol across all build variants of this model. The 10.8V nominal rail and 3-cell Li-ion configuration match what the system board expects during charge negotiation — no voltage mismatch, no rejected cell error on boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the SH782 platform and monitored BMS communication. The protection circuit responded correctly to charge termination at 12.6V and engaged undervoltage cutoff cleanly at the low-cell threshold — no spurious shutdowns during the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on the SH782:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically appears after any 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\"\u003eWhy the SH782 BIOS reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SH782 firmware stores charge cycle count, rated capacity, and health data in EEPROM on the original battery pack. When you install a new cell, the BIOS reads fresh EEPROM data that does not match the learned profile from the old pack. The system flags this as a health anomaly rather than recognising it as a new cell. Running the battery learn cycle — one full discharge to hibernate then a full uninterrupted charge — overwrites the cached data and resolves the warning without any BIOS update or reset tool.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSH782 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell hits a voltage cliff under combined CPU and display load at a state of charge the gauge has mapped incorrectly. The shutdown is real — the cell voltage drops below the BMS protection threshold — but the percentage displayed is wrong. Complete two full discharge-to-hibernate and uninterrupted charge cycles, and the fuel gauge IC will remap its curve to the new cell, typically resolving the early cutoff by cycle three.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409671225434,"sku":"BWCS-FUH782NB-1","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409671258202,"sku":"BWCS-FUH782NB-2","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409671290970,"sku":"BWCS-FUH782NB-3","price":123.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUH782NB-1.webp?v=1779580400","url":"https:\/\/batteryweb.com\/products\/fujitsu-lifebook-sh782-replacement-battery-108v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
