Dell Venue 8 Pro 74XCR Replacement Battery 3.7V 4800mAh

Dell Venue 8 Pro — 3.7V Li-Polymer Replacement Battery (74XCR / VXGP6)

This 3.7V, 4800mAh Li-Polymer battery replaces the original cell in the Dell Venue 8 Pro tablet, including variants listed as T01D and T10D-5830. It matches the OEM voltage, capacity, and physical footprint of the factory battery. Swap it in when the original cell no longer holds a usable charge or fails to power the tablet through a normal work session.

• Venue 8 Pro, T01D, T10D-5830 compatibility: These model numbers share the same battery bay dimensions, connector pinout, and BMS communication protocol. One cell fits all three because Dell used a single battery platform across this hardware revision.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Venue 8 Pro platform. The BMS handshake completed cleanly, charge termination triggered correctly at full voltage, and the Windows battery reporting stack picked up the cell without error flags.
• Fuel gauge recalibration after install: After fitting this battery, run the tablet down to automatic shutoff under normal use — display on, Wi-Fi active — then charge uninterrupted to 100% without interruption. This single full cycle lets the fuel gauge IC recalibrate against the new cell and corrects the inaccurate percentage readings that commonly appear after a swap.

Tablet shutting down at 15–25% remaining after battery replacement

The Venue 8 Pro draws combined load from the display backlight and Wi-Fi simultaneously during active use. On a new cell the fuel gauge IC is still calibrated to the old cell's voltage curve, so it misreads the actual charge state. The tablet's power manager hits its low-voltage cutoff threshold earlier than the real charge level warrants, triggering a shutdown. One full discharge-to-shutoff followed by an uninterrupted charge to 100% resets the calibration and moves the cutoff point back to the correct level.

Windows reporting incorrect battery percentage after a cell swap

Windows reads battery percentage through the ACPI battery interface, which pulls data from the fuel gauge IC embedded in the battery pack. That IC ships pre-calibrated to a reference curve, not to your specific usage pattern. Until it runs one full discharge and charge cycle on your device, it reports against the wrong baseline and the percentage jumps or reads high. Run the tablet to automatic shutoff, then charge straight to 100% — the gauge corrects itself against the new cell's actual voltage floor at approximately 3.0V.
