HP Slate 10 Plus Replacement Battery 3.7V 8000mAh

HP Slate 10 Plus / 2201 — 3.7V Li-Polymer Replacement Battery (PR-3159167)

This 3.7V, 8000mAh lithium-polymer battery replaces the original PR-3159167 (also listed as 781101-001) in the HP Slate 10 Plus and model 2201 tablet. It restores power to the 10-inch touchscreen when the factory cell no longer holds a usable charge. Capacity and voltage match the original specification exactly.

• Slate 10 Plus and 2201 compatibility: Both model numbers share the same 3.7V power rail, connector pinout, and BMS handshake protocol — a single cell covers both variants without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Slate 10 Plus platform. The BMS accepted the cell cleanly, voltage held steady across display-on and WiFi-active load states, and the charge IC reached termination without interruption.
• Post-installation calibration: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% before use. This resets the fuel gauge IC against the new cell and corrects the inaccurate percentage readings that typically appear after a battery swap.

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

This happens when the fuel gauge IC is still calibrated to the old, degraded cell. The reported percentage does not match actual cell voltage, so the protection circuit triggers a cutoff at what looks like 20% but is already near the cell's minimum safe voltage. The combined load of the backlit display and active WiFi creates a voltage sag that accelerates this mismatch. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — after that single cycle the gauge recalibrates and the early shutoff stops.

Fast charging not available after swapping the PR-3159167

The HP Slate 10 Plus negotiates charge rate during the first accepted charge cycle after a battery change. Until that negotiation completes, the charge IC defaults to a lower input current as a precaution. This is not a fault with the replacement cell. Connect the original HP charger and allow one full charge to complete without interrupting — subsequent sessions will accept the higher charge rate once the handshake is established.
