It replaces OEM part numbers LIP8020, LIP8082, EM-G320L1, EM-G320L2, ES1-2200, and ES1-4400. If your original cell has degraded or failed, this restores mobile power to the Green 710.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGreen 710 compatibility:\u003c\/strong\u003e\n    All listed OEM part numbers share the same 14.8V four-cell configuration, connector pinout, and BMS handshake protocol — that is why the Green 710 platform accepts each of them interchangeably.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, discharge, and full-load cycles on the Green 710. The BMS communicated correctly with the system board, and charge termination triggered cleanly at capacity without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Green 710:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This forces the Green 710's BIOS battery learn cycle to reset against the new cell and clears the false 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\"\u003eGreen 710 shutting down at 20–30% after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old, degraded cell. The new cell has a steeper voltage curve than the worn original, so the system reads a voltage cliff and triggers an emergency shutdown even though charge remains. It is not a fault with the replacement cell. Run two full discharge-to-hibernate cycles followed by uninterrupted full charges — after that, the fuel gauge IC recalibrates and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Green 710 BIOS reads health data from the battery's EEPROM. When a new cell is installed, the EEPROM data does not match the charge history the BIOS has stored from the old cell, triggering a poor health flag. This is a data mismatch, not a physical defect. Complete one full discharge-to-hibernate cycle, then charge to 100% without interruption — the BIOS learn cycle will overwrite the stale EEPROM reference and the warning clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410823905370,"sku":"BWCS-ECG320NB-1","price":75.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410823938138,"sku":"BWCS-ECG320NB-2","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410823970906,"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\/northstar-green-710-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
