It replaces OEM part numbers FMVNBP219, FPB0280, and FPCBP345Z. Fit this when the original cell no longer holds charge or the laptop has lost all mobile portability.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLifeBook UH572 fitment:\u003c\/strong\u003e\n    The UH572 uses a slim 5.90mm li-polymer pack to stay within ultrabook thickness limits. The connector pinout, BMS data lines, and voltage rail all match the OEM spec — the BIOS will recognise the new cell and begin its charge cycle without any manual override.\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 the UH572 platform. The BMS handshake completed correctly, charge acceptance started immediately, and the protection circuit tripped at the expected low-voltage cutoff under load — no false positives.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the UH572:\u003c\/strong\u003e\n    After fitting, run one full discharge to hibernate-cutoff then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot 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 fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LifeBook UH572 BIOS reads health data stored in the battery's EEPROM. When a new cell arrives, that EEPROM carries factory baseline data that doesn't match what the BIOS recorded for the old pack. The system flags a mismatch and displays a poor health or unknown status warning — not a fault with the new cell. One complete discharge-to-hibernate followed by a full uninterrupted charge clears the learn cycle and resets the health readout to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUH572 shutting down without warning at 20–30% charge 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 gauge shows 20–30% remaining, but the cell voltage has already dropped below the minimum the CPU and display can sustain under combined load — the system cuts power instantly rather than gracefully hibernating. The fix is two to three full discharge-and-recharge cycles so the fuel gauge IC maps the new cell's discharge profile accurately. After calibration, the shutdown point will track actual cell voltage instead of the stale curve from the old pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409745313882,"sku":"BWCS-FUH572NB-1","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409745346650,"sku":"BWCS-FUH572NB-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409745379418,"sku":"BWCS-FUH572NB-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUH572NB-1.webp?v=1779580647","url":"https:\/\/batteryweb.com\/products\/fujitsu-lifebook-uh572-replacement-battery-148v-2450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
