It replaces dead or degraded original packs and restores untethered operation. 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\u003e799 \/ G720 \/ G799 platform fit:\u003c\/strong\u003e\n    These three Eee PC variants share the same battery bay dimensions, 14.8V rail, and connector pinout. The BMS handshake protocol is identical across the cluster, so one cell swaps cleanly into all three without adapter plates or wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an Eee PC 799 chassis. The BMS accepted the cell on first connection, negotiated charge current correctly, and the protection circuit tripped at the expected low-voltage cutoff without event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on Eee PC netbooks:\u003c\/strong\u003e\n    After installing, run one full discharge down to the hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell data and clears the inaccurate health warning that appears after every cell swap on this platform.\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 after replacement on the Eee PC 799\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Eee PC stores battery health data in the original cell's EEPROM. When a new cell goes in, the BIOS compares live readings against stale EEPROM values from the old pack and flags a mismatch as poor health. This is not a fault with the replacement cell — it is a data conflict. Running one full discharge-to-hibernate followed by a full uninterrupted charge writes fresh reference data and clears the warning. After two to three cycles the fuel gauge IC recalibrates and the health flag drops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEee PC 799 shutting down at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the netbook cuts out while the OS still shows 20–30% remaining, the fuel gauge IC has not yet mapped the new cell's discharge curve. The old curve had a different voltage cliff point, and the system trips the shutdown threshold early. This is not a capacity defect — the cell still holds charge. Run two to three full discharge-to-hibernate and full-charge cycles. By the third cycle the gauge IC recalibrates against the new cell and the cutoff aligns to the correct low-voltage point near 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410823610458,"sku":"BWCS-ECG320NB-1","price":75.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410823643226,"sku":"BWCS-ECG320NB-2","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410823675994,"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\/maxtech-799-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
