It replaces OEM part numbers C41N1416 and 0B200-01250100. The physical dimensions are 253.96 × 100.28 × 10.00mm — confirm these against your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG501JW and N501JW platform fit:\u003c\/strong\u003e\n    These models share an identical battery bay footprint, connector pinout, and 15.2V four-cell Li-Polymer BMS handshake. The same part number covers both chassis 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 G501JW under combined CPU and display load. The BMS held the 15.2V rail steady through charge and discharge cycles, and the protection circuit triggered correctly at low-voltage cutoff without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on ROG BIOS:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap on ROG hardware.\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 the new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ROG G501JW BIOS stores charge history and wear data in EEPROM on the old cell. When a new cell goes in, the BIOS reads no historical data and flags the battery as degraded or unknown. This is a firmware state issue, not a fault with the replacement cell. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — the BIOS learn cycle rewrites the health data against the new cell's actual capacity. After two to three cycles, the health indicator updates correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC calibrates its state-of-charge estimate against the old cell's voltage curve. A new cell has a slightly different discharge curve, so the IC calls empty well before the actual cutoff voltage. The laptop shuts down because the OS acts on the IC's reading, not the raw voltage. Force two full discharge-to-hibernate cycles without interruption — by the second cycle the fuel gauge IC has mapped the new cell's curve and the reading stabilises. If the problem persists past three cycles, check that the BIOS is not applying a custom low-battery threshold above the default 15.2V rail floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409725063258,"sku":"BWCS-AUN501NB-1","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409725096026,"sku":"BWCS-AUN501NB-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409725128794,"sku":"BWCS-AUN501NB-3","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUN501NB-1.webp?v=1779580541","url":"https:\/\/batteryweb.com\/products\/asus-n501jw-1a-replacement-battery-152v-3700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
