It fits the XT3's battery bay directly and covers all major OEM part numbers including 1NP0F, 37HGH, 9G8JN, H6T9R, KJ321, and RV8MP. Capacity is 3600mAh (39.96Wh) — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude XT3 compatibility:\u003c\/strong\u003e\n    Dell's XT3 uses a shared battery platform across its convertible SKUs. All OEM part numbers listed above draw from the same 11.1V three-cell architecture and use the same connector and BMS handshake — so one cell covers the full XT3 production run.\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 the XT3 platform. The BMS negotiated correctly with Dell's EC firmware, charge current ramped as expected, and the cell reached full capacity without triggering a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the XT3:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff under normal load, 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 Dell's EC firmware.\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 after fitting a new cell on the XT3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDell's EC firmware reads health data from the battery's EEPROM. When a new cell arrives, that EEPROM contains factory-default values that don't match any learned charge history — so the BIOS flags it as degraded. This is a firmware interpretation issue, not a fault with the cell itself. Run one full discharge-to-hibernate then a full uninterrupted charge and the BIOS learn cycle will rewrite those values against the new cell's actual behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eXT3 shutting 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 against the new cell's voltage curve. The OS reads an inaccurate state-of-charge and the laptop shuts down as the cell hits its actual low-voltage cutoff — while the gauge still shows charge remaining. Under combined CPU and display load, the XT3 draws enough current to accelerate the voltage drop toward that cliff. Two to three full discharge-and-charge cycles recalibrate the fuel gauge IC; after that, the shutdown percentage should track accurately down to the configured cutoff, typically around 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409791877210,"sku":"BWCS-DEXT30NB-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409791909978,"sku":"BWCS-DEXT30NB-2","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409791942746,"sku":"BWCS-DEXT30NB-3","price":108.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEXT30NB-1.webp?v=1779580887","url":"https:\/\/batteryweb.com\/products\/dell-latitude-xt3-replacement-battery-111v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
