It replaces OEM part number EM-G600L2S directly. If your original battery no longer holds charge or the laptop only runs on AC power, this cell restores portable operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e7079, 7084, 7091, and 8000 compatibility:\u003c\/strong\u003e\n    These four models share the same 14.8V battery rail, connector pinout, and BMS communication protocol — which is why one part number covers all of them. Swapping between these models does not require a different cell or firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the 7079 platform. The BMS handshake completed correctly, the charging circuit accepted the cell without fault codes, and protection cut-off triggered at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Advent 7079 series:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle. Skipping this step causes Windows to report incorrect capacity or flag a health warning that has nothing to do with the new cell.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThe Advent 7079 BIOS stores battery health data in EEPROM and compares it against the connected cell on every boot. When you swap in a new battery, the EEPROM still holds wear data from the old one, so the system flags the replacement as degraded — even though the cell is fresh. This is not a fault with the replacement battery. Run one full discharge-to-hibernate cycle followed by a complete uninterrupted charge. After one or two full cycles, the BIOS recalibrates against the new cell and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop 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 loses calibration after a cell swap — the percentage on screen no longer matches actual cell voltage. The laptop hits the low-voltage protection threshold while Windows still shows 20–30% remaining and cuts power without warning. The fix is a calibration cycle: let the laptop discharge fully to automatic hibernate, then charge straight to 100% without interruption. Repeat this two to three times until the fuel gauge tracks correctly. After calibration, shutdown should not occur above 5–8% displayed charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409799020634,"sku":"BWCS-ADM800NB-1","price":139.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409799053402,"sku":"BWCS-ADM800NB-2","price":160.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409799086170,"sku":"BWCS-ADM800NB-3","price":176.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADM800NB-1.webp?v=1779580970","url":"https:\/\/batteryweb.com\/products\/advent-advent-7079-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
