It fits using OEM part numbers SQU-702 and SQU-703, along with a range of compatible references including 916C6080F and EUP-P3-4-22. The connector, BMS handshake, and voltage rail match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEasyNote SB85 and related models:\u003c\/strong\u003e\n    The SB85, MZ35, MZ36, and F0335 share the same battery bay geometry, 11.1V three-cell voltage rail, and BMS communication protocol. That is why a single SKU covers all of them — the BIOS fuel gauge IC reads the same EEPROM data structure across the range.\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 discharge cycles on EasyNote-platform hardware. The BMS accepted the charge handshake without error flags, and the BIOS battery health screen cleared to normal status after one full calibration cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install discharge cycle:\u003c\/strong\u003e\n    After fitting, let the laptop run on battery until it hibernates at low-voltage cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that almost always appears after a 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 immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EasyNote BIOS stores charge history and health data in the old cell's EEPROM. When a new cell goes in, that data is blank or mismatched, so the BIOS flags poor health before any real usage data exists. This is not a fault with the replacement cell — it is a data gap. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%, and the BIOS will rewrite its health baseline against the new cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the BMS triggers a hard cutoff before the displayed percentage reaches zero. It typically appears in the first few cycles before the fuel gauge IC has calibrated against the new cell's discharge curve. Run two or three full discharge-to-hibernate cycles to let the IC remap the voltage curve. After calibration, the reported percentage at shutdown should align with actual remaining capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409812848730,"sku":"BWCS-LXE510NB-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409812881498,"sku":"BWCS-LXE510NB-2","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409812914266,"sku":"BWCS-LXE510NB-3","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LXE510NB-1.webp?v=1779581043","url":"https:\/\/batteryweb.com\/products\/packard-bell-easynote-sb85-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
