It restores portable operation when the original cell has degraded or failed. Fits the same physical bay and connector as the factory battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT2 4K GT, 4K, T1, and T2 compatibility:\u003c\/strong\u003e\n    These models share the same 10.8V three-cell architecture, connector pinout, and BMS communication protocol — one cell fits all four variants 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 and discharge cycles on a T2 4K GT unit. The BMS handshake completed correctly, charge termination triggered at the expected voltage ceiling, and the protection circuit responded normally to load fluctuations under CPU and display stress.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the T2 4K GT:\u003c\/strong\u003e\n    After fitting this cell, run it down fully until the laptop hibernates, then charge uninterrupted to 100% without unplugging early. 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 Vulcan T2 4K GT reads EEPROM data stored on the battery's BMS chip to display health metrics. When a new cell arrives, the EEPROM carries factory baseline values that don't match your unit's learned charge history. The BIOS flags this mismatch as poor health even though the cell is new. One full discharge-to-hibernate followed by a complete uninterrupted charge resolves this — the BIOS rewrites its learned data against the new cell and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under full load before the fuel gauge reaches zero. At peak CPU and display draw, the battery voltage sags faster than the gauge — calibrated to lighter loads — can track. The gauge shows 20–30% remaining, but actual cell voltage has already hit the protection floor. Run the full discharge-calibration cycle described above, and confirm the cell voltage at rest reads above 11.1V after a full charge before dismissing a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409623547994,"sku":"BWCS-MRX600NB-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409623580762,"sku":"BWCS-MRX600NB-2","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409623613530,"sku":"BWCS-MRX600NB-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MRX600NB-1.webp?v=1779580234","url":"https:\/\/batteryweb.com\/products\/vulcan-t2-4k-gt-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
