It replaces OEM part numbers PDNM2, 579TY, F1KTM, 7CJRC, and 21X15. It fits the standard battery bay with the original connector and BMS pinout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE7470 and E7270 platform fit:\u003c\/strong\u003e\n    Both the E7470 and E7270 run the same 11.1V battery rail and share the same physical housing, connector, and BMS handshake protocol. One cell covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an E7470 under sustained CPU and display load. The BMS held stable voltage through the discharge curve and handed off cleanly to AC when plugged in. No false low-battery shutdowns occurred during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Dell Latitude:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it reaches hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to complete against the new cell and clears the inaccurate health warning that appears after every battery 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  \u003cp class=\"bpw-desc-p\"\u003eDell's BIOS reads health data from the battery's EEPROM, which stores charge history from the previous cell. When a new cell is installed, that EEPROM data does not match the new cell's actual state, so the BIOS flags it as degraded before any cycles have run. This is not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by an uninterrupted full charge. After that cycle completes, the BIOS health indicator resets to reflect the new cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% battery remaining after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC calibrates its remaining-capacity estimates against charge and discharge data collected over multiple cycles. On a fresh cell, those estimates are pulled from the old cell's profile and are often wrong under real load. When the CPU and display spike simultaneously, actual cell voltage drops faster than the gauge predicts, and the system hits the low-voltage cutoff while still showing 20–30% on screen. Run two to three full discharge-to-hibernate and full-charge cycles. By the third cycle the fuel gauge IC has enough data to track the new cell's voltage curve accurately, and early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409742528602,"sku":"BWCS-DEL747NB-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409742561370,"sku":"BWCS-DEL747NB-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409742594138,"sku":"BWCS-DEL747NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEL747NB-1.webp?v=1779580582","url":"https:\/\/batteryweb.com\/products\/dell-latitude-e7470-replacement-battery-111v-3300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
