It uses OEM part numbers 05VC2M and MXV9V. The cell slots into the same bay, connects to the same BMS, and communicates with Dell's BIOS battery management layer.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 7300 \/ 5300 \/ 7400 platform fit:\u003c\/strong\u003e\n    These models share the same 7.6V two-cell Li-Polymer architecture, connector pinout, and BIOS-side EEPROM handshake. The BMS on each talks to the same Dell battery manager firmware, so one cell covers the full cluster without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Latitude 7300 and monitored BMS communication, charge acceptance across full cycles, and voltage behaviour under combined CPU-plus-display load. The cell held voltage above the BIOS low-battery cutoff threshold throughout discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Dell ultrabooks:\u003c\/strong\u003e\n    After fitting, run a full discharge to hibernate cutoff, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Dell Power Manager after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Latitude 7300 BIOS flags a new battery as \"poor health\"\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDell's BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported state. A fresh cell has no charge history written yet, so the BIOS interprets zero-cycle EEPROM data as a degraded or unknown battery. This is not a fault with the replacement cell. Running one full discharge-to-hibernate then a complete charge cycle writes initial data to the EEPROM and clears the warning in Dell Power Manager and the BIOS setup screen.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLatitude shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom points to the fuel gauge IC losing calibration against the new cell's actual chemistry. The IC still uses capacity curves mapped to the old, degraded cell, so it misjudges the remaining charge and triggers a shutdown long before the cell is actually depleted. The fix is two or three full discharge-and-charge calibration cycles, which force the fuel gauge to relearn the new cell's voltage-to-capacity curve. After calibration, the gauge tracks accurately and shutdowns at low percentage stop. Confirm the gauge is recalibrated by checking battery percentage in Windows against an actual measured voltage of approximately 7.2–7.4V at the 20% mark.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409664082010,"sku":"BWCS-DEL730NB-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409664114778,"sku":"BWCS-DEL730NB-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409664147546,"sku":"BWCS-DEL730NB-3","price":86.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEL730NB-1.webp?v=1779580339","url":"https:\/\/batteryweb.com\/products\/dell-latitude-13-7300n052l7300-d1716fcn-replacement-battery-76v-7400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
