It slots into the XP14 Gen 12 chassis and restores portable operation when the original cell has degraded or failed. Voltage and connector pinout match the factory specification for this generation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXP14 Gen 12 platform fit:\u003c\/strong\u003e\n    The Gen 12 board uses a 15.2V four-cell architecture with a specific BMS handshake over the SMBus line. Cells from other XP14 generations run a different voltage rail and will not satisfy the firmware handshake on this board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full-load discharge, and BMS fault recovery on the XP14 Gen 12. The protection circuit tripped correctly at the low-voltage cutoff and reset cleanly on reconnect with no SMBus error codes logged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration tip:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate cutoff under normal load, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears 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 fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XP14 Gen 12 BIOS reads health data from EEPROM stored on the battery's BMS — not from live cell measurement. When a new cell goes in, the EEPROM contains factory defaults that do not match the BIOS's learned profile from the old pack. The firmware flags this mismatch as degraded health. One complete discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learned profile and clears the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly while the OS gauge still shows 20–25% remaining\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 discharge curve. The IC is still using voltage-to-capacity mappings built from the old, degraded cell. Under combined CPU and display load the new cell hits a voltage cliff that the uncalibrated gauge has mapped 20–25% too high. Run two or three full discharge-to-hibernate cycles and the gauge IC will remap the curve accurately against the new cell's chemistry.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409537957978,"sku":"BWCS-CLN400NB-1","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409537990746,"sku":"BWCS-CLN400NB-2","price":107.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409538023514,"sku":"BWCS-CLN400NB-3","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLN400NB-1.webp?v=1779579965","url":"https:\/\/batteryweb.com\/products\/tuxedo-book-xp14-gen-12-replacement-battery-152v-3050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
