It replaces OEM part CF-VZSU88U directly. Field professionals running the FZ-G1 without access to charging infrastructure will find this pack restores full operating capacity to the device.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFZ-G1 and Toughbook G1 fitment:\u003c\/strong\u003e\n    Both model designations share the same battery bay geometry, connector pinout, and BMS handshake protocol. One replacement cell covers the full G1 platform — no adapter or firmware workaround needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, load, and BMS communication checks on a G1 unit. The BMS completed authentication, accepted a full charge cycle, and reported accurate state-of-charge data throughout discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the FZ-G1:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle on the FZ-G1 and clears the inaccurate health warning that appears 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 After Installing a New Cell on the FZ-G1\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe FZ-G1 BIOS reads health data stored in the battery's EEPROM — not from live cell measurements. When a new cell goes in, that EEPROM carries a different charge history than the system expects, so the BIOS flags poor health immediately. This is a data mismatch, not a fault with the replacement pack. Run one full discharge-to-hibernate then a full uninterrupted charge. After that learn cycle completes, the BIOS recalibrates against the new cell's EEPROM and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFZ-G1 Shutting Down at 20–30% State-of-Charge Shown on Screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated to the new cell's discharge curve. The gauge reads 25% remaining, but the cell voltage has already dropped below the minimum the system will sustain under combined CPU and display load — so the tablet cuts power before the displayed percentage reaches zero. The fix is two or three full discharge-and-charge cycles without interruption. By the third cycle, the fuel gauge IC maps the new cell's voltage profile accurately and the early shutdown stops. Target a resting cell voltage of 11.1V at what the gauge shows as 50% to confirm calibration is on track.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409514070106,"sku":"BWCS-FNG100NB-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409514102874,"sku":"BWCS-FNG100NB-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409514135642,"sku":"BWCS-FNG100NB-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNG100NB_1.webp?v=1779579852","url":"https:\/\/batteryweb.com\/products\/panasonic-fz-g1-replacement-battery-111v-9600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
