: Standard 6-cell versions typically offer ~4000 mAh to 5200 mAh.
Based on common diagnostic observations, the pins are typically numbered from left to right when looking at the battery's connector: Pins 1 & 2: Negative (- / Ground) Hp Mu06 Notebook Battery Pinout Configuration
The spacing between the pins on the MU06 connector is extremely narrow. Standard multimeter probes can easily bridge two pins accidentally. Use insulated alligator clips or thin copper needles to avoid catastrophic shorts. : Standard 6-cell versions typically offer ~4000 mAh

What do you currently have on hand (e.g., multimeter, bench power supply, Arduino)?
The HP MU06 notebook battery pinout is designed with safety and data communication at its core. By understanding the roles of the Ground, SMBus, System Present, and Positive pins, hardware technicians can effectively diagnose battery health issues outside of the laptop environment. If you are building a custom DIY power bank using an MU06 pack, always ensure Pin 6 is properly managed and that your load circuits respect the safety limits established by the internal BMS.
The System Management Bus (SMBus) is a two-wire communication protocol based on I2C. The SCL pin delivers the clock signal required to synchronize data transfers between the laptop’s embedded controller (EC) and the battery's smart chip.
