About this replacement
HP Envy M7-N000 / M7-N100 Series — 11.1V Li-ion Replacement Battery (HSTNN-PB6L)
This 11.1V, 4400mAh (48.84Wh) Li-ion battery replaces the original cell in the HP Envy M7-N000 and M7-N100 series laptops. It fits models including the M7-N011dx and M7-N014dx, and is cross-referenced against OEM part numbers HSTNN-PB6R, MC04, MC06, and TPN-C123 among others. Use it when the original cell no longer holds a charge or fails to register in the BIOS.
- M7-N000 and M7-N100 platform fit: Both series run the same 11.1V battery rail, share the same physical connector, and use the same BMS handshake protocol — which is why a single cell covers both lines without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the M7-N series platform. The BMS communicated correctly with the HP EC firmware, accepted a full charge without interruption, and reported accurate state-of-charge data to the OS.
- Post-install discharge cycle on the M7-N series: After fitting this cell, run the laptop on battery until it hibernates from low charge, then charge it uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
Why the Envy M7-N BIOS reports poor battery health immediately after a swap
The HP Envy M7-N series stores battery health data in EEPROM on the battery's protection circuit board. When you install a new cell, the BIOS reads stale or mismatched EEPROM values from the factory state and flags it as degraded or unknown. This is not a fault with the replacement cell — it is a calibration gap. One full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the EC firmware to rewrite the learn cycle data and clear the warning.

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The OS reads a voltage that looks like 25% remaining, but the cell hits its low-voltage cutoff point before the gauge catches up — the laptop shuts down without warning. The fix is two to three full discharge and charge cycles, which let the fuel gauge IC map the new cell's voltage curve accurately. After calibration, the cutoff should align with the OS reading at or below 5% remaining.
