About this replacement
Dell Latitude 11 5175 / 5179 Series — 7.6V Li-Polymer Replacement Battery (VHR5P)
This 7.6V, 4600mAh (34.96Wh) Li-Polymer battery replaces the original cell in the Dell Latitude 11 5175 and 5179 tablet-notebooks. It fits both standard and Tablet-designated variants of those models. OEM part numbers covered include VHR5P, RFH3V, XRHWG, T04E, and T04E001.
- Latitude 5175 / 5179 platform fit: Both the 5175 and 5179 share the same low-profile 7.6V two-cell Li-Polymer architecture, the same T04E board connector, and the same BMS handshake protocol. One replacement cell covers the full range of variants listed.
- Bench tested on actual hardware: We cycled this cell on a Latitude 5175 unit and confirmed the BMS handshake completed without fault flags, the fuel gauge IC accepted the new cell data, and the charge circuit progressed through CC and CV phases without tripping a false overvoltage cut.
- Post-install calibration on Latitude 5175 / 5179: After fitting this battery, run the laptop down to hibernate cutoff on a normal workload, then charge uninterrupted to 100% without waking the system. 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.
Why the Latitude 5175 shuts down at 20–30% after a battery swap
The Latitude 5175 uses a fuel gauge IC that builds a discharge curve map from past cycles. When a new cell goes in, that map still references the old cell's voltage-to-capacity curve. Under full CPU and display load, voltage drops faster than the old map expects, and the system interprets it as a cliff-edge cutoff and shuts down — even though the gauge shows charge remaining. Running two to three full discharge-to-hibernate-then-full-charge cycles lets the fuel gauge IC rebuild its curve against the new cell chemistry. After calibration, the reported percentage and actual cutoff voltage should align at or below 3.0V per cell.
BIOS showing wrong Wh rating after fitting a replacement cell
The Wh value the BIOS displays comes from EEPROM data stored on the battery's protection circuit board, not from a live measurement. Some replacement cells ship with EEPROM values that differ slightly from the factory-rated 34.96Wh figure. This is a data field difference, not a capacity fault. If the discrepancy matters for asset management or power profiles, confirm the reading in Dell's battery diagnostics tool under the "Design Capacity" field rather than the BIOS summary screen.
