About this replacement
HP 11-BE0013DX Tablet — 7.7V Li-Polymer Replacement Battery (DM02XL)
This is a 7.7V, 3950mAh (30.42Wh) Li-Polymer battery for the HP 11-BE0013DX 2-in-1 touchscreen tablet. It replaces OEM part numbers DM02XL, HSTNN-OB2T, M74961-AC1, and M75108-005. It also fits the 47Z80AV and 4R0Y4UA variants of the HP 11-inch Touchscreen 2-in-1.
- HP 11-inch 2-in-1 series fitment: These models share the same 7.7V power rail, identical connector pinout, and the same BMS handshake protocol — which is why one cell covers the 11-BE0013DX, 47Z80AV, and 4R0Y4UA without modification.
- Bench tested on actual hardware: We ran this cell through charge-discharge cycles on the HP 11-inch platform and confirmed the BMS accepted the cell, reported state-of-charge correctly after calibration, and held voltage within spec under combined display and WiFi load.
- Fuel gauge reset after installation: After fitting this battery, run the tablet down to automatic shutoff — do not force it off manually — then charge uninterrupted to 100%. This gives the fuel gauge IC a clean reference point against the new cell and clears the inaccurate percentage readings that almost always appear after a swap.
HP 11-BE0013DX shutting down at 15–25% remaining
This shutdown pattern points to a voltage cliff — the point where cell voltage drops faster than the fuel gauge predicts, especially under the combined draw of the IPS display at full brightness and an active WiFi connection. The BMS hits its low-voltage cutoff before the OS-reported percentage reaches zero. A degraded or freshly installed uncalibrated cell will trigger this consistently. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — after that cycle, the fuel gauge IC recalibrates and the shutdowns at 15–25% stop.
Fast charging not resuming after battery replacement on the HP 11-inch 2-in-1
USB-PD negotiation on the HP 11-BE0013DX requires at least one completed charge cycle before the charge controller accepts higher current from a PD adapter. With a new cell installed, the charge IC defaults to a conservative rate until it has a verified state-of-charge history. Plug in the original HP charger — not a third-party adapter — and let it complete one full charge from below 20% to 100% without interruption. After that cycle, USB-PD negotiation resumes at the correct wattage and fast charging returns.
