It fits the 9365-D6801TS, D6701TS, D6705TS, D3605TS, and fifteen additional 9365 variants. The slim 3.74mm profile matches the tight chassis clearance of this 2-in-1 form factor exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXPS 13-9365 platform fit:\u003c\/strong\u003e\n    Every 9365 variant in this series shares the same voltage rail, battery connector pinout, and SMBus BMS handshake. That shared architecture is why all listed models take the same physical cell and communicate identically with the EC firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a 9365 board and confirmed the BMS initialised without fault codes, charge current ramped normally through CC\/CV stages, and the EC accepted the new cell without throwing a battery-not-recognised error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap learn cycle on the XPS 9365:\u003c\/strong\u003e\n    After fitting, discharge the laptop fully until it hibernates, then charge uninterrupted to 100% without waking the system mid-cycle. This resets the BIOS battery learn cycle 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 immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XPS 9365 stores historical charge data in the old cell's EEPROM. When a new cell goes in, the BIOS compares the new cell's state against cached data from the previous pack and flags a mismatch as degraded health. This is a firmware artefact, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by a complete uninterrupted charge cycle allows the BIOS learn cycle to rewrite its reference data against the new cell. After one or two calibration cycles the health indicator returns to normal.\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 has not yet calibrated against the new cell's actual discharge curve. The IC is still using voltage-to-capacity mapping from the old, degraded pack, so it misreads the voltage cliff and triggers a shutdown well above actual depletion. It is not a faulty cell. Force one full discharge to hibernate-cutoff — do not interrupt it — then charge to 100%. After two full cycles the fuel gauge recalibrates and the cutoff point tracks correctly to the real cell voltage, which at full load on the 9365 should not drop below 6.8V before the EC flags low battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409691738202,"sku":"BWCS-DEX680NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409691770970,"sku":"BWCS-DEX680NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409691803738,"sku":"BWCS-DEX680NB-3","price":116.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEX680NB-1.webp?v=1779580453","url":"https:\/\/batteryweb.com\/products\/dell-xps-13-9365-d6801ts-replacement-battery-76v-5850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
