It fits multiple XPS 13 9300 configurations and replaces OEM part numbers including 2XXFW, 722KK, FP86V, P117G, WN0N0, and variants. The cell slots into the same bay as the original and connects to the same BMS-controlled charging circuit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXPS 13 9300 platform fit:\u003c\/strong\u003e\n    All XPS 13 9300 variants share the same 7.6V two-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. That's why a single part number covers dozens of sub-configurations across this generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an XPS 13 9300 unit, confirmed the BMS accepted the EEPROM handshake on first boot, and verified charge regulation kicked in correctly through a full 0–100% cycle. No rejected cell errors appeared in the Dell Power Manager log.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After installing, run one full discharge 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 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 after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XPS 13 9300 BIOS reads health status from EEPROM data stored in the battery's controller chip. A new cell ships with factory EEPROM values that don't match the laptop's charge history, so the BIOS flags it as degraded even though the cell is new. This is a calibration mismatch, not a fault. Run one full discharge-to-hibernate then a full uninterrupted charge — the BIOS battery learn cycle rewrites its internal state against the new cell and the warning clears. After two or three cycles, the health indicator in Dell Power Manager should read normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop 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 calibrated against the new cell's actual voltage curve. The old calibration data predicts a safe floor voltage that no longer maps correctly to the replacement cell, so a shutdown triggers before the battery is genuinely empty. It's not a cell defect — it's a measurement offset. Force the fuel gauge to recalibrate by letting the laptop discharge fully to hibernate cutoff at least twice, then charging back to 100% without interruption. After two full cycles, the OS percentage readout stabilises and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409645731930,"sku":"BWCS-DEX931NB-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409645764698,"sku":"BWCS-DEX931NB-2","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409645797466,"sku":"BWCS-DEX931NB-3","price":124.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEX931NB-1.webp?v=1779580171","url":"https:\/\/batteryweb.com\/products\/dell-xps-13-9300-replacement-battery-76v-6500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
