It also fits the FZ-G1A, FZ-G1B, and iCON CS35 10, among others. Swap it when the original cell no longer holds a charge through a full field shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFZ-G1 series compatibility:\u003c\/strong\u003e\n    The FZ-G1A, FZ-G1B, and FZ-G1R all run the same 10.8V battery rail and share an identical connector and BMS handshake protocol. OEM part numbers FZ-VZSU84U, FZ-VZSU84AK, FZ-VZSU88U, and the rest of the FZ-VZSU84 family all cross to this cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against the FZ-G1R's BMS under full CPU and display load. The BMS accepted the cell without a reject fault, charge current stepped down correctly at the 4.2V-per-cell threshold, and the protection circuit tripped cleanly at the low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the FZ-G1R:\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 and clears the inaccurate health warning that appears after every cell swap on the FZ-G1 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 FZ-G1R BIOS reports poor battery health immediately after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe FZ-G1R stores charge cycle count and capacity data in EEPROM on the original battery's fuel gauge IC. When you install a new cell, the BIOS reads that EEPROM as blank or mismatched and flags the battery health as poor or unknown. This is not a fault with the new cell. Run the full discharge-to-hibernate and uninterrupted charge cycle once, and the BIOS learn cycle overwrites the stale EEPROM data. After one or two full cycles, the health indicator returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFZ-G1R 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 has not yet calibrated against the new cell's actual discharge curve. The OS reads a percentage based on voltage estimates from the old cell's profile, but the new cell hits its voltage cliff at a different point. Under combined CPU and display load, the tablet shuts down before the gauge reaches 0%. Run two full discharge-and-recharge cycles without interruption. After the second cycle, the fuel gauge IC recalibrates and the reported percentage will track actual remaining capacity accurately down to approximately 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409733517402,"sku":"BWCS-CRF100NB-1","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409733550170,"sku":"BWCS-CRF100NB-2","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409733582938,"sku":"BWCS-CRF100NB-3","price":123.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CRF100NB-1.webp?v=1779580583","url":"https:\/\/batteryweb.com\/products\/panasonic-fz-g1r-replacement-battery-108v-4100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
