It fits the GM501GM-EI017T, GM501GM-EI007T, GM501GS-EI017T, GM501GS-XS74, and over 30 additional GM501 variants. The 4-cell configuration matches the original voltage rail and connector pinout exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGM501 series compatibility:\u003c\/strong\u003e\n    Every GM501 variant on the fit list shares the same 15.4V four-cell architecture, connector housing, and BMS communication protocol — so one cell works across the entire platform 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 GM501GM under sustained CPU and GPU load. The BMS held the charge curve steady through full draw cycles, with no overcurrent trip or thermal cutoff during stress testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates at cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell 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\"\u003eBIOS reporting poor battery health immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GM501's BIOS reads EEPROM data from the installed cell to calculate health status. When a new cell goes in, the EEPROM values don't match the BIOS's learned baseline from the old battery, so Windows and the BIOS both flag the replacement as degraded — even though it's brand new. This isn't a fault with the cell. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% rewrites the learn cycle baseline. After two to three full cycles, the BIOS health readout will normalise to reflect actual cell capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop 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 hasn't calibrated against the new cell's actual discharge curve. The GM501 draws hard under gaming load — full CPU plus display plus dGPU simultaneously — and if the fuel gauge IC is still referencing the old cell's voltage-to-capacity map, it misjudges the voltage cliff. The laptop shuts off before the displayed percentage reaches zero. To fix this, run two to three full discharge-to-cutoff cycles so the fuel gauge IC can build an accurate map of the new cell's voltage curve. After calibration, shutdowns at 20–30% stop and the displayed percentage tracks real remaining capacity correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409692721242,"sku":"BWCS-AUM501NB-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409692754010,"sku":"BWCS-AUM501NB-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409692786778,"sku":"BWCS-AUM501NB-3","price":112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUM501NB-1.webp?v=1779580453","url":"https:\/\/batteryweb.com\/products\/asus-gm501gm-ei017t-replacement-battery-154v-3550mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
