It also fits the Green 320 platform sharing the same connector and voltage rail. OEM part numbers covered include LIP8020, LIP8082, EM-G320L1, EM-G320L2, ES1-2200, and ES1-4400.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG320 \/ G720 \/ G799 platform compatibility:\u003c\/strong\u003e\n    These three Alphatop models share the same 14.8V four-cell configuration, battery bay connector, and BMS handshake protocol — a single cell SKU covers the group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and load cycles. The BMS communicated correctly with the host system, accepted a full charge without early cutoff, and held voltage under sustained CPU and display load without triggering a protective shutdown.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Alphatop G320:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to the hibernate cutoff point, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the Alphatop firmware displays 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\"\u003eAlphatop G320 shutting down at 20–30% charge shown\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a firmware fault. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track — the system sees voltage fall below the safe floor and cuts power before the displayed percentage reaches zero. The old battery's discharge curve was mapped into the BIOS; a new cell with fresh capacity doesn't match that stored curve yet. Run two full calibration cycles — full discharge to hibernate, full uninterrupted charge — and the BIOS learn cycle will remap against the new cell's actual voltage curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting wrong Wh rating after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure shown in BIOS or system info reads from EEPROM data stored on the battery's BMS chip, not from live measurement. A replacement cell's EEPROM is programmed to its rated chemistry specification, which can differ slightly from the previous cell's stored value. This is not a fault — the cell capacity is correct at 65.12Wh. If the BIOS value still looks wrong after one full charge cycle, pull the AC adapter, discharge fully to hibernate, then recharge to 100% to trigger a fresh EEPROM read.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410824003674,"sku":"BWCS-ECG320NB-1","price":75.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410824036442,"sku":"BWCS-ECG320NB-2","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410824069210,"sku":"BWCS-ECG320NB-3","price":98.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG320NB-big.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/ecs-elitegroup-alphatop-g320-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
