It replaces OEM part GX-17S directly. Fits the notebook's standard battery bay without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX5S and X3 Plus compatibility:\u003c\/strong\u003e\n    These Aorus models share the same 14.8V four-cell architecture and GX-17S connector pinout. The BMS handshake protocol is identical across the X5S and X3 Plus v5\/v7 variants, so a single cell fits all listed configurations without firmware conflict.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the X5S platform. The BMS negotiated correctly with the Aorus charge controller on first contact — no voltage mismatch or protection-trip during the load test at full CPU and display draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Aorus:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's chemistry and clears the inaccurate health warning that appears after every cell swap on Aorus notebooks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Aorus X5S shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe X5S fuel gauge IC maps its discharge curve against the original cell's EEPROM data. A new cell has a different voltage-versus-capacity slope, so the gauge miscalculates the remaining charge. Under full CPU and GPU load, the new cell hits its low-voltage cliff before the gauge expects it, and the system cuts power to protect the cells. The fix is the battery learn cycle — full discharge to hibernate, uninterrupted charge to 100% — repeated two to three times until the gauge recalibrates against the new chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reports battery health as \"poor\" or \"replace now\" immediately after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Aorus BIOS reads health data from the old cell's EEPROM and compares it to the new cell's reported state — they don't match, so it flags a fault. This is not a defect in the replacement cell. Running a full discharge-to-hibernate followed by a complete uninterrupted charge resets the learn cycle. After one to two full calibration cycles, the BIOS health status should update to reflect the actual condition of the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409565089882,"sku":"BWCS-ARX500NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409565122650,"sku":"BWCS-ARX500NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409565155418,"sku":"BWCS-ARX500NB-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARX500NB-1.webp?v=1779580013","url":"https:\/\/batteryweb.com\/products\/aorus-x5s-replacement-battery-148v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
