It replaces OEM part numbers C41N1524 and 0B200-01250200. The pack slots into the same bay and connects to the same BMS handshake points as the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG501VW and UX501VW series fit:\u003c\/strong\u003e\n    These models share the same 15.2V four-cell Li-Polymer configuration, connector pinout, and BMS communication protocol — which is why one pack covers 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 charge, discharge, and BMS handshake verification on a G501VW unit. The BMS accepted the pack, charge current ramped correctly through CC\/CV stages, and no fault codes triggered at either end of the cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate 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\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe G501VW BIOS reads health data from EEPROM stored on the battery pack itself, not from live cell voltage. When you install a replacement, the EEPROM data is either blank or carries a different cycle count than the system expects. The BIOS interprets this mismatch as a degraded pack and flags it accordingly. Running one full learn cycle — discharge to hibernate, then a full uninterrupted charge — writes fresh calibration data and clears the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% remaining on the gauge\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 voltage curve. The old calibration map doesn't match the new pack, so the gauge hits a cliff and the system shuts down before the real capacity is exhausted. It is not a fault with the replacement battery. Do two full discharge-to-hibernate and charge-to-100% cycles — by the second cycle the gauge IC recalibrates and the reported percentage tracks actual cell voltage correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409675976794,"sku":"BWCS-AUG501NB-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409676009562,"sku":"BWCS-AUG501NB-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409676042330,"sku":"BWCS-AUG501NB-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUG501NB-1.webp?v=1779580399","url":"https:\/\/batteryweb.com\/products\/asus-rog-g501vw-bsi7n25-replacement-battery-152v-3950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
