Understanding the pinout configuration of the HP MU06 is essential whether you are trying to test a battery's health with a multimeter, revive a deeply discharged pack, or repurpose the cells for a DIY electronics project. Overview of the HP MU06 Battery
The pins are typically numbered from left to right when looking at the battery’s connector face. Description Ground (GND) Main negative power terminal. Ground (GND) Parallel negative power terminal for high current. SMBus Clock (C) Synchronous clock line for battery communication. SMBus Data (D) Data line for reporting capacity, cycles, and temperature. Temperature (T) Thermistor pin for battery temperature sensing. System Present
HP uses dual ground pins to distribute the current load. When the laptop draws high current under heavy workloads, sharing the load across two pins prevents overheating and contact degradation. Hp Mu06 Notebook Battery Pinout Configuration

Lithium-ion (typically 6 cells arranged in a 3S2P configuration) Nominal Voltage: 10.8V or 11.1V Charge Voltage Limit: 12.6V Standard Capacity: 4400 mAh to 5200 mAh (47 Wh to 57 Wh)
If you disconnect the internal cells from the original BMS board during a rebuild, the chip will likely lock itself permanently. Special software (like EV2300/EV2400 tools) is required to reset HP battery microcontrollers. Ground (GND) Parallel negative power terminal for high
10.8V or 11.1V (depending on whether the individual cells are rated at 3.6V or 3.7V). Fully Charged Voltage: ~12.6V Capacity: Typically 4400 mAh to 5200 mAh.
