HP Slate 7 Extreme Replacement Battery 3.7V 4000mAh 32102102

HP Slate 7 Extreme — 3.7V Li-Polymer Replacement Battery (32102102)

This 3.7V, 4000mAh lithium-polymer battery replaces part number 32102102 in the HP Slate 7 Extreme 7-inch Android tablet. It restores power to the display, processor, and wireless functions when the original cell has degraded or failed. Capacity is 14.8Wh — matching the original specification.

• Slate 7 Extreme fitment: The 32102102 cell is specific to this tablet's chassis — the connector orientation, BMS handshake protocol, and physical dimensions (109 x 101 x 3.50mm) are matched to the Slate 7 Extreme's charge IC and battery slot.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Slate 7 Extreme platform. The BMS accepted the cell on first connection, reported state-of-charge correctly after one calibration cycle, and held voltage through display and WiFi combined load without triggering a low-voltage cutoff.
• Fuel gauge recalibration after swap: After installing this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the tablet's fuel gauge IC against the new cell capacity and eliminates the inaccurate percentage readings that appear immediately after a swap.

Slate 7 Extreme shutting down at 15–25% battery remaining

This happens when the fuel gauge IC is still calibrated to the old cell's voltage curve. The tablet reads voltage from the new cell and maps it against the wrong reference — so it hits a false low-voltage threshold before the cell is actually empty. Running one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% gives the IC a fresh reference point. After that cycle, shutdown behaviour at low charge levels returns to normal.

Fast charging unavailable after battery replacement on the Slate 7 Extreme

The Slate 7 Extreme's charge controller negotiates current delivery based on the battery's accepted charge state from the previous session. On a brand-new or freshly installed cell with no history, the controller defaults to a conservative charge rate until it completes one full accepted cycle. Connect the tablet to the original HP charger and allow one complete charge from low to 100% without interruption. Fast charge availability resumes after that first cycle completes.
