Dell Latitude 14 7430 Replacement Battery 15.2V 3600mAh

Dell Latitude 14 7430 / 15 7530 Series — 15.2V Li-Polymer Replacement Battery (07KRV)

This is a 15.2V, 3600mAh (54.72Wh) Li-Polymer battery for the Dell Latitude 14 7430 D1GX0, Latitude 14 7430 2-in-1, Latitude 15 7530, and related models in the 7430/7530 series. It replaces OEM part numbers 07KRV and H4PVC. The cell dimensions match the original bay at 247.50 × 95.00 × 6.70mm, so no modification is needed for fitment.

• Latitude 7430 / 7530 platform fitment: These models share the same 15.2V four-cell Li-Polymer architecture, identical connector pinout, and BMS handshake protocol — which is why one cell covers both the 14-inch and 15-inch chassis across multiple build variants.
• Bench tested on actual hardware: We ran this cell on a Latitude 7430 unit and confirmed the BMS authenticated correctly, charge cycling initiated without fault codes, and discharge held a stable voltage curve down to the hardware cutoff threshold.
• BIOS learn cycle after install: After fitting this cell, run the laptop down to hibernate cutoff on battery power only, then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Dell Latitude hardware.

Laptop shutting down at 20–30% remaining after battery swap

The Latitude 7430 uses a fuel gauge IC that was calibrated against the original cell's discharge curve. When a new cell goes in, the IC's stored data no longer matches actual cell behaviour — so it calls an early shutdown when voltage drops faster than predicted under CPU and display load. This is not a fault with the replacement cell. Run two or three full discharge-to-hibernate and charge-to-100% cycles to let the fuel gauge IC recalibrate against the new chemistry. After calibration cycles, shutdown-at-20% behaviour typically resolves.

BIOS reporting new cell Wh rating as incorrect in system info

Dell's BIOS reads the Wh rating from EEPROM data embedded in the battery's BMS chip, not from live cell measurement. A replacement cell's EEPROM may report a rated figure that differs slightly from the original's stored value, causing the system information screen to show a mismatched Wh figure. This is a data field discrepancy — it does not affect charge or discharge behaviour. If the figure matters for asset management purposes, verify it against the physical cell label, which reflects actual rated capacity.
