It fits the Latitude 6430U-100TB and 6430U-102TB variants using OEM part numbers 7HRJW, 312-1424, 7XHVM, 312-1425, 6FNTV, XX1D1, TRM4D, and 9KGF8. If your unit shuts down unexpectedly or no longer holds a charge, this cell is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLatitude 6430u fit group:\u003c\/strong\u003e\n    The 6430U-100TB and 6430U-102TB share the same three-cell Li-Polymer architecture, connector pinout, and BMS handshake as the base 6430u. All three pull from the same OEM part range, so one cell covers all three build codes without adapter or 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 a mixed CPU and display load cycle. The BMS reported state-of-charge correctly, charge termination triggered at full voltage, and no fault codes were thrown during discharge to hibernate cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the 6430u:\u003c\/strong\u003e\n    After fitting, run one 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 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 after replacement on the 6430u\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Latitude 6430u stores learned capacity data in EEPROM tied to the original cell. When a new cell arrives, the BIOS compares its current readings against stale EEPROM values and flags the battery as degraded or unknown — even though the new cell is at full capacity. This is a firmware read mismatch, not a fault with the replacement. Running one complete discharge-to-hibernate then an uninterrupted full charge resets the learn cycle. After two to three cycles, the BIOS health indicator aligns with actual cell state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLatitude 6430u shutting down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge still maps voltage to state-of-charge using data from the old, degraded cell, so it hits the low-voltage shutdown threshold earlier than the display percentage suggests. The new cell physically has charge remaining, but the system doesn't know that yet. Run two full discharge-to-hibernate and full-recharge cycles — by the third cycle, the fuel gauge IC recalibrates and the shutdowns stop. If the problem persists past three cycles, check that the cell connector is fully seated and re-read the BIOS battery status at 25% remaining to confirm the voltage is above 10.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409795940442,"sku":"BWCS-DE6430NB-1","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409795973210,"sku":"BWCS-DE6430NB-2","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409796005978,"sku":"BWCS-DE6430NB-3","price":146.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE6430NB-1.webp?v=1779580887","url":"https:\/\/batteryweb.com\/products\/dell-latitude-6430u-replacement-battery-111v-3200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
