It replaces OEM part numbers V4N84 and VG661. Swap it in when the original cell no longer holds charge through a full gaming or productivity session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAlienware X14 R1 and R2 compatibility:\u003c\/strong\u003e\n    Both generations share the same 11.4V three-cell Li-Polymer configuration, identical connector pinout, and BMS handshake protocol — one battery fits 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 through full charge and discharge cycles on the X14 platform. The BMS communicated correctly with the EC, charge current tapered at capacity, and no over-voltage or thermal fault codes were triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Alienware X14:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the EC flags after every cell swap.\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 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDell's embedded controller reads health data stored in the old cell's EEPROM and compares it against the new cell's initial readings. The mismatch triggers a poor health flag — this is an EC calibration issue, not a fault with the replacement cell. Run the battery down to hibernate cutoff under normal load, then charge to 100% without interruption. After one or two full cycles, the EC rewrites its reference data and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlienware X14 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder full CPU and GPU load, the X14 draws sustained current that the fuel gauge IC cannot accurately predict from a freshly installed cell. The cell hits a voltage cliff before the displayed percentage reaches zero, and the EC cuts power to protect the system. The fuel gauge IC needs two to three calibration cycles against the new cell's actual discharge curve before the percentage readout becomes accurate. Force a full discharge to hibernate on battery power each time until the shutdowns stop occurring above 15%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409529864282,"sku":"BWCS-DEX142NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409529897050,"sku":"BWCS-DEX142NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409529929818,"sku":"BWCS-DEX142NB-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEX142NB-1.webp?v=1779579904","url":"https:\/\/batteryweb.com\/products\/dell-alienware-x14-r1-replacement-battery-114v-7050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
