It replaces OEM part numbers 7CXN6, HRGYV, JHT2H, T3JWC, and XMT81. Install it when the original cell no longer holds charge or the system shuts down under load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 7410 2-in-1 fit group:\u003c\/strong\u003e\n    The 7410 2-in-1 and the 7000 7410 14\" Touchscreen share the same battery bay dimensions, connector pinout, and BMS handshake protocol — all confirmed against Dell service manual A00. This cell seats flush in both chassis variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full-load discharge, and BMS cutoff on a Latitude 7410 2-in-1 unit. The BMS authenticated cleanly, BIOS registered correct Wh rating, and the protection circuit tripped at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Latitude 7410:\u003c\/strong\u003e\n    After installing, run one full discharge until the system hibernates, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears 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\"\u003eBIOS reporting battery health as poor after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Latitude 7410 BIOS reads health data from the battery's EEPROM. When a new cell is installed, that EEPROM carries factory baseline data that doesn't match the BIOS's learned cycle history from the old cell. The system flags this mismatch as degraded health — even on a brand-new battery. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the BIOS learn cycle and resolves the warning. After two or three full cycles, the health indicator should read normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% shown after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a fuel gauge calibration issue, not a faulty cell. The fuel gauge IC on the Latitude 7410 maps voltage curves from the old cell — a new Li-Polymer cell has a slightly different discharge curve, so the gauge misjudges remaining capacity. Under full CPU and display load, the system hits the actual voltage floor well before the displayed percentage reaches zero. Run two to three full discharge-to-hibernate and full-charge cycles to let the fuel gauge IC recalibrate against the new cell's voltage profile. After calibration, the shutdown threshold should track accurately to below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409657561178,"sku":"BWCS-DET810NB-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409657593946,"sku":"BWCS-DET810NB-2","price":120.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409657626714,"sku":"BWCS-DET810NB-3","price":131.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DET810NB-1.webp?v=1779580340","url":"https:\/\/batteryweb.com\/products\/dell-latitude-7410-2-in-1-replacement-battery-76v-6400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
