It replaces OEM part numbers SQU-702 and SQU-703, among others. Capacity is 48.84Wh — matching the original cell specification for these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e7201 \/ 7211 \/ 7301 \/ 7302 compatibility:\u003c\/strong\u003e\n    These four models share the same 11.1V battery rail, physical connector, and BMS handshake protocol. One cell fits all four because the charge controller IC and cutoff thresholds are identical 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 charge and discharge cycles on a 7301 unit. The BMS negotiated correctly, charge current ramped as expected, and the protection circuit tripped cleanly at low-voltage cutoff — no false shutdowns at partial state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on Advent laptops:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge through to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on these machines.\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 7201 series BIOS reads health data stored in the battery's EEPROM, not from live cell measurements. When a new battery arrives, the EEPROM may carry default or mismatched values that the BIOS interprets as degraded. This is not a fault with the replacement cell. Running one full discharge-to-hibernate then a complete uninterrupted charge forces the BIOS to rewrite its learned capacity data against the new cell. After two to three full cycles, the health indicator normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated to the new cell's actual voltage curve. The OS shows 20–30% remaining, but the cell voltage has already dropped below the load threshold under combined CPU and display draw. The gauge is reading against the old cell's profile. Run two full discharge-to-hibernate cycles back-to-back — by the second cycle, the fuel gauge IC recalibrates and the shutdown point drops to near 0% as expected. Verify recovery by checking the reported voltage in the OS power settings — it should read above 10.8V at 15% shown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409813012570,"sku":"BWCS-LXE510NB-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409813045338,"sku":"BWCS-LXE510NB-2","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409813078106,"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\/advent-7201-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
