HP SlateBook 101 MA02XL Replacement Battery 7.4V 3350mAh

HP SlateBook 10 X2 — 7.4V Li-Polymer Replacement Battery (MA02XL)

This is a 7.4V, 3350mAh (24.79Wh) Li-Polymer replacement battery for the HP SlateBook 10 X2 series, including the SlateBook 10-H001SE X2 and the 10-h010NR. It slots into the tablet dock base that powers the detachable screen unit and restores full portability when the original cell has degraded.

• SlateBook 10 X2 dock platform: These models share a common 7.4V two-cell Li-Polymer rail with the same connector pinout and BMS handshake protocol. The dock unit, not the screen, houses this battery — confirm you are replacing the correct component before ordering.
• Bench tested on actual hardware: We cycled this cell through the SlateBook dock BMS and confirmed it negotiates charge termination correctly at 8.4V. The protection circuit tripped at the expected under-voltage threshold with no error codes logged.
• Post-install calibration on the SlateBook X2 dock: After fitting, run the dock down until the system hibernates, then charge uninterrupted to 100% before reattaching the screen. This resets the fuel gauge IC against the new cell and clears the inaccurate battery health warning that appears after every cell swap.

Why the SlateBook 10 X2 reports poor battery health right after a cell swap

The HP EC firmware stores learned capacity data from the previous cell in EEPROM. When a new cell goes in, the stored data no longer matches actual chemistry, so the system flags the battery as degraded or unknown — even on a brand-new replacement. This is not a fault with the cell. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% forces the firmware to relearn capacity against the new cell and clears the warning.

SlateBook 10 X2 shutting down while the dock gauge still shows 20–25%

This happens when the cell can no longer hold voltage under combined CPU and display load — it hits a voltage cliff before the fuel gauge reaches zero. The gauge IC calibrated itself against the old degraded cell, so its empty-point estimate is now too low for the new cell's actual cutoff curve. A full discharge-to-hibernate cycle corrects this by giving the IC a real zero-voltage reference point. After one full cycle, the shutdown threshold should align with the gauge reading 0–5%.
