It fits the E7440, E7440 Touch, and the broader Latitude 14 7000 series. Cross-reference OEM part numbers include 3RNFD, G95J5, V8XN3, GV7HC, PFXCR, and 451-BBFT among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE7440 and E7450 series compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V battery rail, connector pinout, and BMS handshake protocol. A single cell works across all four fit models listed because Dell held the electrical spec consistent across that generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an E7450 and monitored BMS communication through the SMBus interface. Charge acceptance, cycle counting, and state-of-charge reporting all registered correctly in Dell's battery diagnostics.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the E7450:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates on low battery, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Dell Power Manager after a cell swap.\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 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDell's BIOS reads EEPROM data embedded in the battery's SMBus controller. When a new cell is installed, that EEPROM reflects factory values — not the usage history the BIOS expects to see from a broken-in cell. The system flags this mismatch as degraded health before any real-world cycles have run. Running the battery learn cycle — full discharge to hibernate cutoff, then a full uninterrupted charge — lets the BIOS overwrite its stored parameters against the new cell's actual performance data. After one or two cycles, the health status normalises.\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 is a voltage cliff issue, not a capacity fault. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track — the system hits the hardware undervoltage cutoff before the displayed percentage reaches zero. It is most pronounced on degraded cells, but can also appear during the first few cycles on a new cell before the fuel gauge IC has calibrated against it. Run two full discharge-to-hibernate and charge-to-100% cycles to give the gauge IC accurate data points. After calibration, the shutdown threshold should align to a displayed level below 10%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409745805402,"sku":"BWCS-DE7450NB-1","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409745838170,"sku":"BWCS-DE7450NB-2","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409745870938,"sku":"BWCS-DE7450NB-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE7450NB-1.webp?v=1779580647","url":"https:\/\/batteryweb.com\/products\/dell-latitude-14-e7450-replacement-battery-111v-3500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
