It replaces OEM part numbers G15KN-11-16-3S1P-0, GI5KN-00-13-3S1P-0, and GI5KN-11-16-3S1P-0. It restores battery-powered operation on both models where the original cell has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX6 and X5 shared platform:\u003c\/strong\u003e\n    Both models run the same 11.1V three-cell series configuration and use the same connector pinout and BMS handshake protocol. One replacement cell covers both SKUs without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the X6 platform. The BMS communicated correctly with the system, charge termination triggered at the expected voltage ceiling, and the fuel gauge IC accepted the new cell data after calibration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle for X6\/X5:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it hibernates at the low-voltage cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell 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\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vulcan X6 BIOS reads health data stored in the battery's EEPROM. When a new cell arrives, that EEPROM data does not match the charge history the BIOS expects, so it flags the battery as degraded even though the cell is new. This is a data mismatch, not a hardware fault. Running one complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and pushes fresh cycle data into the EEPROM. After two to three full cycles the health reading normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge estimates remaining charge based on the old cell's behaviour, so it reads 25% while the real cell voltage has already dropped below the safe threshold under CPU and display load. The laptop's protection circuit cuts power before the gauge catches up. Run two full discharge-to-hibernate and full-recharge cycles. After calibration the gauge tracks real cell voltage accurately and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409612374106,"sku":"BWCS-VLX600NB-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409612406874,"sku":"BWCS-VLX600NB-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409612439642,"sku":"BWCS-VLX600NB-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VLX600NB-1.webp?v=1779580234","url":"https:\/\/batteryweb.com\/products\/vulcan-x6-replacement-battery-111v-4050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
