About this replacement
Dell Venue 10 Pro 5056 — 7.4V Li-Polymer Replacement Battery (GFKG3)
This 7.4V, 4100mAh (30.34Wh) lithium-polymer cell replaces the original GFKG3 battery in the Dell Venue 10 Pro and Venue 10 Pro 5056 tablets. It fits the same internal bay and connects to the same BMS circuit as the factory unit. OEM part numbers GFKG3, 0VN25R, and VN25R all reference this same cell.
- Venue 10 Pro and 5056 fitment: Both models share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. A single cell covers either variant — no adapter or modification needed.
- Bench tested on actual hardware: We cycled this cell through charge, full discharge, and BMS communication checks. The fuel gauge IC reported capacity correctly after two calibration cycles, and the protection circuit tripped at the correct low-voltage threshold.
- Post-install discharge cycle for the Venue 10 Pro: After fitting this cell, let the tablet discharge fully until it hibernates on its own, then charge it 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.
BIOS reporting battery health as poor after fitting a new GFKG3 cell
The Venue 10 Pro stores battery health data in EEPROM on the old cell. When a new cell goes in, the BIOS reads no cycle history and flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%. After two to three cycles, the BIOS learn routine rewrites the health register and the warning clears.
Tablet shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. The Venue 10 Pro's display and CPU together draw enough current that a miscalibrated gauge reads the voltage cliff on the new cell as 20–30% when the cell is actually near depletion. The fix is not a hardware swap — it is a calibration issue. Run two full discharge-to-hibernate cycles without interrupting the charge, and the gauge recalibrates its reference points. After those cycles, the percentage readout aligns with the actual cell voltage, which should sit above 7.0V at 20% remaining.
