It replaces OEM part numbers C31N1602 and 0B200-02090000. The slim 4.10mm cell profile matches the UX330UA's tight chassis clearance exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUX330UA platform compatibility:\u003c\/strong\u003e\n    All UX330UA variants share the same 11.55V three-cell configuration, identical connector pinout, and the same BMS handshake protocol — which is why one cell fits the full model range without firmware or connector changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a UX330UA board under a mixed CPU-plus-display load. The BMS held the 11.55V rail steady and reported state-of-charge accurately to the ACPI layer after two calibration cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this cell, 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 that appears after every cell swap on the UX330UA.\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 after fitting the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe UX330UA BIOS reads health data from EEPROM registers that carry figures from the original cell. A fresh cell has no matching EEPROM history, so the BIOS flags it as degraded immediately after install. This is a calibration gap, not a fault with the replacement. Run one full discharge-to-hibernate followed by an uninterrupted full charge. After two to three cycles, the fuel gauge IC overwrites the stale EEPROM data and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down suddenly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. The new cell hits a voltage cliff under combined CPU and display load before the OS gauge reaches zero, triggering an immediate shutdown. The OS is reading a curve that no longer matches the physical cell. Discharge fully to hibernate cutoff twice in a row — each cycle trains the fuel gauge IC against the new cell's actual voltage profile and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409674698842,"sku":"BWCS-AUZ330NB-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409674731610,"sku":"BWCS-AUZ330NB-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409674764378,"sku":"BWCS-AUZ330NB-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUZ330NB-1.webp?v=1779580400","url":"https:\/\/batteryweb.com\/products\/asus-zenbook-ux330ua-fb161t-replacement-battery-1155v-4800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
