It cross-references OEM part numbers A42-G75, 0B110-00070000, and 90-N2V1B1000Y. Install it when the original cell no longer holds a charge or the system won't run unplugged.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG75 series compatibility:\u003c\/strong\u003e\n    The G75, G75V, G75VM, and G75VW all use the same 14.8V battery rail and share an identical connector and BMS handshake protocol. One cell fits the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a G75VW. The BMS accepted the charge handshake immediately, balanced all four cells correctly, and held voltage above 14.4V under sustained CPU and GPU load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the G75:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until Windows forces hibernate at the low-voltage cutoff — do not plug in early. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the G75 BIOS displays 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 G75 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe G75 BIOS stores discharge curve data from the previous cell in its battery learn table. When a new cell is installed, the stored curve no longer matches actual voltage behaviour. Under full CPU plus GPU load, the new cell's voltage drops faster than the old curve predicts, and the BIOS triggers an emergency shutdown before the displayed percentage reaches zero. This isn't a fault in the replacement cell — it's a calibration mismatch. One full discharge-to-hibernate followed by an uninterrupted full charge clears the old curve and maps the new one correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" or \"replace\" immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G75 BIOS reads health status from EEPROM data written during the battery's factory cycle count — a brand-new cell ships with minimal cycle data, which the BIOS can misread as a degraded unit. This warning typically clears after one or two full calibration cycles once the fuel gauge IC has mapped the new cell's actual capacity. If the warning persists after two full cycles, check that the BIOS is on the latest firmware — Asus issued updates for the G75 line that corrected how the battery controller interprets low-cycle EEPROM states. Update via MyAsus or the Asus support page for your specific G75 model.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409800527962,"sku":"BWCS-AUG75NB-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409800560730,"sku":"BWCS-AUG75NB-2","price":127.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409800593498,"sku":"BWCS-AUG75NB-3","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUG75NB-1.webp?v=1779580970","url":"https:\/\/batteryweb.com\/products\/asus-g75-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
