Using a multimeter (set to DC Volts, 20V range), measure between:
If you are attempting to charge or discharge the MU06 battery outside of a laptop using a benchtop power supply or an active load tester, follow these strict rules:
Never attempt to charge the pack by forcing raw DC voltage into the power pins without current limitations. Safe charging requires a CC/CV (Constant Current/Constant Voltage) profile matching the 3S configuration limits (Max 12.6V charging voltage). Hp Mu06 Notebook Battery Pinout Configuration

When looking directly at the battery connector with the locking tabs facing upward and counting from , the pins map out to specific electrical functions. Pin Number Signal Name Description Pin 1 (+) Plus / VCC Main positive power output / charging input Pin 2 (+) Plus / VCC Parallel secondary positive link (redundancy) Pin 3 SCL (Clock) I2C / SMBus Clock line for data transmission Pin 4 SDA (Data) I2C / SMBus Data line for status communication Pin 5 SYS / CID System Present / Battery Insertion Detection pin Pin 6 (-) Minus / GND Main system ground / negative terminal Pin 7 (-) Minus / GND Parallel secondary system ground (redundancy) Detailed Pin Function Breakdown 1. The Power Terminals (Pins 1, 2, 6, and 7) Using a multimeter (set to DC Volts, 20V
To help tailor any further technical steps or diagnostic advice, could you share a bit more context? Let me know:
The HP MU06 battery utilizes a standardized . When looking directly at the male slot connector on the battery pack with the plastic guide rails facing upwards, the pins are counted from left to right. When looking directly at the battery connector with
The HP MU06 is one of the most widely used laptop battery models in HP's history. It powers massive lineups of legacy laptops, including the HP Pavilion, Compaq Presario, and HP Envy series. For electronics hobbyists, repair technicians, and DIYers, understanding the pinout configuration of this battery is essential for testing, cell replacement, or repurposing the lithium-ion pack for external projects.
Never allow your microcontroller's 5V data pins to come into direct contact with the 11.1V power pins (+V_BAT), as this will instantly destroy your logic boards. Critical Safety Considerations
