It replaces OEM part numbers C32N1415 and 0B200-01250000. Fit the battery when the original no longer holds charge or fails to register in the BIOS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUX501 and N501VW platform fit:\u003c\/strong\u003e\n    These models share the same 11.4V three-cell Li-Polymer rail, identical connector pinout, and the same BMS handshake protocol — so one cell pack covers the full UX501 and N501VW 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 on a ZenBook Pro UX501J under combined CPU and display load. The BMS held the voltage rail steady through repeated high-draw cycles and triggered thermal cutoff only at the rated upper limit — no false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the ZenBook Pro:\u003c\/strong\u003e\n    After fitting, run the laptop from 100% down to hibernate cutoff without plugging in — do not interrupt. Then charge uninterrupted back to 100%. This resets the BIOS battery learn cycle and clears the false \"poor health\" warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZenBook Pro UX501 shutting down at 20–30% shown on screen\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff — the cell voltage drops faster than the fuel gauge IC can track under combined CPU and 4K display load. At around 20–25% indicated, the actual cell voltage falls below the BMS cutoff threshold before the OS registers it. The fuel gauge IC needs two or three full discharge-charge cycles to recalibrate its model against the new cell chemistry. After those cycles, shutdowns at falsely high percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting the replacement battery Wh rating as incorrect\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads Wh data from the battery's EEPROM, which stores the rated capacity written at the factory. If the EEPROM value differs from what the BIOS expects — common after a cell swap — system info may show a mismatched Wh figure. This is an EEPROM data mismatch, not a cell fault. Run a full discharge-to-hibernate then a full uninterrupted charge; the BIOS battery learn cycle will update its stored value. After one complete cycle, recheck the Wh figure in MyASUS or the Windows power report — it should align with the rated 93.48Wh.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409732468826,"sku":"BWCS-AUX501NB-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409732501594,"sku":"BWCS-AUX501NB-2","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409732534362,"sku":"BWCS-AUX501NB-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUX501NB-1.webp?v=1779580542","url":"https:\/\/batteryweb.com\/products\/asus-zenbook-pro-ux501j-replacement-battery-114v-8200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
