It slots into the detachable notebook base and restores full system power to the computing chassis. Capacity matches the factory spec at 45.36Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStylistic Q736 \/ Q737 \/ Q775 compatibility:\u003c\/strong\u003e\n    All three models share the same notebook base form factor, connector pinout, and BMS handshake protocol. The battery management circuit communicates over the same SMBus rail, so a single cell design covers the full trio without firmware conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, full-load discharge, and BMS communication checks on the Stylistic platform. The BMS negotiated correctly, charge termination triggered at the expected cutoff voltage, and no protection trips occurred during sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Stylistic Q737:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. The Stylistic's BIOS battery-learn cycle resets against the new cell data on that first complete pass — skipping it leaves the fuel gauge reading from stale EEPROM data written by the original cell.\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 Stylistic Q737 BIOS reads battery health from EEPROM data embedded in the battery controller — not from live cell measurements. When you swap the physical cell, the EEPROM registers a new device and flags the health status as unknown or degraded until a learn cycle completes. This is not a fault with the replacement cell. Run a full discharge to hibernate, then charge straight to 100% without interruption. After that single cycle the BIOS recalibrates and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStylistic Q737 shutting down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS protection threshold under combined CPU and display load, even though the fuel gauge still shows charge remaining. The gauge is reading a capacity curve calibrated to a degraded old cell — the actual voltage cliff arrives earlier than the software predicts. On a fresh replacement cell the curve shifts, but the gauge IC needs two or three full cycles to re-map it accurately. Force a full discharge to hibernate-cutoff, recharge to 100%, and repeat once more — by the second cycle the shutdown point tracks the displayed percentage correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409686036570,"sku":"BWCS-FUQ736NB-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409686069338,"sku":"BWCS-FUQ736NB-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409686102106,"sku":"BWCS-FUQ736NB-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FUQ736NB-1.webp?v=1779580430","url":"https:\/\/batteryweb.com\/products\/fujitsu-stylistic-q737-replacement-battery-108v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
