It replaces OEM part numbers C41N1712, C41PKC5, 0B200-02380100, 0B200-02380200, and 4ICP4\/72\/75. The GX501VS-XS71 uses a slim 4-cell pack measuring 300.10 x 111.20 x 4.70mm — this cell matches those exact dimensions and the 15.4V rail the BMS expects.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGX501 series compatibility:\u003c\/strong\u003e\n    The GX501VS, GX501GS, GX501VI, and related variants share the same 15.4V four-cell architecture and identical connector pinout. The BMS handshake on these models is tied to that voltage rail, not a proprietary authentication chip, so cell swaps work across the full GX501 lineup without firmware conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a GX501 unit under full CPU and GPU load. The BMS held the 15.4V rail steady through sustained gaming loads and stepped down cleanly at low-cell threshold without triggering an emergency cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap discharge cycle on the GX501:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. The GX501 BIOS carries over the old battery's learn-cycle data. Without this reset, the fuel gauge IC calibrates against stale EEPROM values and reports inaccurate state-of-charge for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GX501VS shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GX501VS runs a combined CPU and discrete GPU load that draws significantly more current than typical productivity laptops. At full load, the cell voltage drops faster than the fuel gauge IC expects based on the old EEPROM discharge curve. When voltage hits the BMS cutoff threshold, the system shuts down — even though the OS still shows 20–30% remaining. This is a calibration mismatch, not a faulty cell. Run two to three full discharge-and-charge cycles so the fuel gauge IC can map the actual discharge curve of the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" or \"replace\" immediately after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Asus BIOS reads health status from EEPROM data written by the original factory cell. A new cell ships with a fresh EEPROM, and the BIOS interprets the mismatch as a degraded battery. This warning clears on its own once the battery learn cycle completes — typically after two or three full charge and discharge cycles. If the warning persists beyond that, force a fresh learn cycle by fully discharging to hibernate, then charging to 100% with the laptop off. Check BIOS battery status again at a full charge to confirm the value has updated.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409670701146,"sku":"BWCS-AUZ501NB-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409670733914,"sku":"BWCS-AUZ501NB-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409670766682,"sku":"BWCS-AUZ501NB-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUZ501NB-1.webp?v=1779580399","url":"https:\/\/batteryweb.com\/products\/asus-rog-zephyrus-gx501vs-xs71-replacement-battery-154v-3100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
