It fits the U24, U24E, U24A, and U24A-PX3210, among other U24 variants. OEM part numbers covered include A31-U24, A32-U24, 07G016JG1875, and 0B110-00130000.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eU24 series compatibility:\u003c\/strong\u003e\n    All U24 variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The 10.8V rail and SMBus communication lines are consistent across the U24E, U24A, and PX3210 configurations, so one cell fits the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a U24E under mixed CPU and display load. The BMS held the charge curve steady, reported state-of-charge correctly to the EC, and did not trip any protection cutoffs during the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on U24:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it hibernates at low charge, then charge uninterrupted to 100%. This gives the BIOS fuel gauge IC a full reference cycle 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\"\u003eWhy the U24 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe U24's embedded controller reads health data from the battery's EEPROM, which stores cycle count and wear metrics from the old cell. A brand-new cell still carries placeholder or mismatched EEPROM values at first boot. Windows or the BIOS interprets those values as degraded capacity, not a fresh cell. Running one full discharge-to-hibernate followed by a complete charge resets the learn cycle and aligns the EEPROM data with the actual cell state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eU24 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't calibrated against the new cell yet, so the percentage shown doesn't match real voltage. Under full CPU plus display load, the cell hits its low-voltage cutoff earlier than the gauge predicts, and the EC shuts the system down to protect the battery. The fix is not a hardware fault — run two to three full discharge and recharge cycles without interruption. After calibration, the gauge tracks accurately and shutdowns at false percentages stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409795514458,"sku":"BWCS-AUU24HB-1","price":104.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409795547226,"sku":"BWCS-AUU24HB-2","price":119.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409795579994,"sku":"BWCS-AUU24HB-3","price":130.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUU24HB-1.webp?v=1779580872","url":"https:\/\/batteryweb.com\/products\/asus-u24-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
