It fits the original battery bay directly and matches the OEM voltage and connector spec. Capacity is rated at 73.26Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF3 and Z-series platform compatibility:\u003c\/strong\u003e\n    The F3Jv, F3E, F3T, Z94, Z96, and related models all run the same 11.1V three-cell architecture with the same BMS handshake protocol. That shared electrical spec is why one cell works across this entire platform — not marketing grouping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full discharge, and BMS re-initialisation on F3-series hardware. The protection circuit tripped correctly at low-cell voltage and the charge controller accepted the new cell without throwing a fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on F3Jv:\u003c\/strong\u003e\n    After installing this battery, run one full discharge down 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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the F3Jv BIOS reports poor battery health immediately after a swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health data from an EEPROM register that holds values written by the original cell. When a new cell goes in, that register still holds the old degraded data. The BIOS sees a mismatch between the fresh chemistry and the stored cycle count, and flags it as poor health. Running one full discharge-to-hibernate and uninterrupted recharge forces the firmware to rewrite the register against the new cell. After one to two full cycles, the health reading normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the gauge\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 is still using the old cell's discharge profile, so it misreads the remaining charge and the laptop cuts power before the real battery floor. It is not a fault with the replacement cell. Run two or three complete discharge-to-hibernate cycles followed by full uninterrupted charges. By the third cycle, the fuel gauge IC recalibrates and the shutdowns stop — the gauge should track correctly down to around 10.5V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410816794714,"sku":"BWCS-AUF3HB-1","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410816827482,"sku":"BWCS-AUF3HB-2","price":135.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410816860250,"sku":"BWCS-AUF3HB-3","price":148.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUF3HB-1.webp?v=1779581181","url":"https:\/\/batteryweb.com\/products\/asus-f3jv-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
