About this replacement
HP Envy M7-N000 Series — 14.4V Li-ion Replacement Battery (HSTNN-PB6L)
This is a 14.4V Li-ion battery rated at 2200mAh (31.68Wh), replacing part number HSTNN-PB6L in the HP Envy M7-N000 and M7-N100 series laptops. It slots into the same bay as the original MC04 and MC06 packs and connects via the same five-pin smart connector. OEM part numbers HSTNN-PB6R, TPN-C123, and 804073-851 are all covered by this cell.
- M7-N000 and M7-N100 platform fit: Both series share the same 14.4V four-cell architecture, BMS handshake protocol, and physical connector pinout — which is why a single cell covers both chassis generations without modification.
- Bench tested on actual hardware: We ran this cell on an M7-N011dx and verified the BMS completed a full charge cycle without tripping an over-voltage cutoff. The BIOS recognised the pack on first boot and reported charge status correctly through Windows Battery Report.
- Post-install calibration for the M7 series: After fitting, run the laptop down to automatic hibernate on battery only — no manual shutdown — then charge uninterrupted to 100%. This single discharge-to-cutoff cycle resets the BIOS battery learn sequence and clears the false "Consider replacing your battery" alert that appears after most cell swaps on this platform.
Why the Envy M7 shuts down at 20–30% charge shown
The M7 platform pulls hard on the CPU and a 15.6-inch display simultaneously under load. When the cell voltage drops below roughly 13.6V under that combined draw, the BMS triggers a protection cutoff before the fuel gauge reaches zero — so Windows shows 20–30% remaining at the moment of shutdown. This is a voltage cliff, not a capacity fault. The fix is a full calibration cycle: discharge to hibernate cutoff, then charge to 100% without interruption. After two to three cycles the fuel gauge IC maps the new cell's discharge curve accurately and the early shutdowns stop.
BIOS showing battery Wh rating as incorrect after swap
The original HSTNN-PB6L EEPROM stores Wh data that the BIOS reads on boot — this value is what Windows and HP Support Assistant display under battery details. A replacement cell carries its own EEPROM value, which may differ slightly from the OEM figure. This is a data mismatch between stored EEPROM metadata and actual cell chemistry, not a fault with the battery itself. Verify the actual pack capacity using HP PC Hardware Diagnostics or run a full Windows Battery Report — the discharge curve data from a completed calibration cycle is the accurate reference, not the static EEPROM figure.
