It fits the Aero 15W-OG4, Aorus X9 DT-CL5M, Aero 15-Y9-9FR4711P, Aero 15 OLED NA, and 96+ additional models sharing the same cell format and connector. If your original battery no longer holds a charge or the system reports critically degraded health, this cell restores full portability.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across Aero and Aorus lines:\u003c\/strong\u003e\n    These Gigabyte laptops share the same 15.2V four-cell architecture, physical footprint, and BMS communication protocol. The connector pinout and fuel gauge IC handshake are identical across the series, so one cell covers a wide model range without firmware differences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, full-load discharge, and BMS cutoff cycles on Aero-series hardware. The BMS accepted the cell immediately, the protection circuit tripped correctly at the low-voltage threshold, and charge termination completed cleanly at 100%.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Gigabyte BIOS:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap — skip it and the gauge stays wrong for weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eGigabyte's BIOS stores learned capacity data from the previous cell in EEPROM. When a new cell goes in, the stored values no longer match the actual chemistry, and the firmware flags it as degraded before a single cycle completes. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate followed by an uninterrupted charge to 100%, and the BIOS recalculates health against the new baseline. After two to three full cycles, the health reading stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts off abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot sustain the voltage rail under combined CPU, GPU, and display load — the cell hits a voltage cliff that the fuel gauge IC has not yet mapped to the correct state-of-charge percentage. The OS gauge is reading a calibration from the old cell and misjudges how much capacity remains. Force a full discharge to the hibernate cutoff point — around 2.5V per cell minimum — then charge fully to 100% without interruption. After two calibration cycles the gauge aligns with actual cell voltage and the premature shutdown stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409607032922,"sku":"BWCS-GTR147NB-1","price":107.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409607065690,"sku":"BWCS-GTR147NB-2","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409607098458,"sku":"BWCS-GTR147NB-3","price":136.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GTR147NB-1.webp?v=1779580171","url":"https:\/\/batteryweb.com\/products\/gigabyte-aero-15w-og4-replacement-battery-152v-6100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
