It fits the Latitude 6430U-100TB and 6430U-102TB variants and crosses to OEM part numbers 312-1424, 7XHVM, 312-1425, 6FNTV, XX1D1, TRM4D, and 9KGF8. The slim 8.90mm profile matches the 6430u's chassis clearance exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 6430u platform fit:\u003c\/strong\u003e\n    All three Latitude 6430u variants share the same 11.1V power rail, identical battery connector, and the same BMS handshake protocol — which is why one cell covers the full model range 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 a Latitude 6430u under sustained CPU and display load. The BMS held the charge curve steady, balancing each cell group without tripping an early cutoff under the ultrabook's combined draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the 6430u:\u003c\/strong\u003e\n    After fitting, discharge fully until the system hibernates, 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\" immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Latitude 6430u BIOS reads health data from EEPROM stored in the old battery's BMS chip. When a new cell arrives, that EEPROM data is either blank or carries the previous cell's degraded history. The BIOS interprets this as a fault and flags the battery as unknown or poor. Running one full discharge-to-hibernate cycle followed by a complete uninterrupted charge forces the BIOS to rewrite its learned capacity data against the new cell. After two to three cycles, the health indicator should return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC still references calibration data from the old, degraded cell. The 6430u's power management system believes the cell has more capacity than it actually has at that moment — then cuts out when voltage drops suddenly under full CPU and display load. The fix is a full calibration cycle: discharge to hibernate cutoff, then charge to 100% without interruption, twice in a row. After calibration, the fuel gauge tracks the new cell's actual voltage curve and the premature shutdown stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409744920666,"sku":"BWCS-DE6430HB-1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409744953434,"sku":"BWCS-DE6430HB-2","price":141.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409744986202,"sku":"BWCS-DE6430HB-3","price":154.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE6430HB-1.webp?v=1779580647","url":"https:\/\/batteryweb.com\/products\/dell-latitude-6430u-replacement-battery-111v-5600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
