Counting from left to right (with the battery label facing up and the connector facing you):

| Pin Number | Function | Description & Notes | | :--------- | :--------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | 1 | | Main battery negative terminal; connects directly to the laptop's ground. | | 2 | Battery Negative (B-) | Often multiple pins are used for the main power path to handle higher current loads safely and provide redundancy. | | 3 | System Management Bus Clock (SMBCLK) | This pin carries the clock signal for the SMBus, synchronizing data transmission between the battery and the laptop. | | 4 | System Management Bus Data (SMBDAT) | This pin carries the actual data, such as voltage, current, temperature, and remaining capacity. | | 5 | Battery Presence | This pin is used by the laptop to detect if a battery is physically installed. It is often pulled to ground within the battery pack. | | 6 | Temperature (Thermistor) | Connected to a negative temperature coefficient (NTC) thermistor within the battery pack. Its resistance decreases as temperature rises, allowing the laptop to monitor battery temperature and prevent overheating. Often 10kOhm at 25°C. | | 7 | Battery Positive (B+) | Main battery positive terminal. | | 8 | Battery Positive (B+) | Multiple pins for the main power path. | | 9 | Cell Tap (Optional) | In some smart batteries, an extra pin connects to the junction between two cells to allow the battery management system (BMS) to monitor the midpoint voltage of the series cell string for cell balancing. | Hp Mu06 Notebook Battery Pinout Configuration

Connected to the negative terminal of the cell string.

This article provides an in-depth breakdown of the HP MU06 battery pinout, its electrical characteristics, safety protocols, and a step-by-step guide to testing the battery safely. Technical Specifications of the HP MU06 SMBus Clock line for communication with the laptop's

Used for I2C/SMBus communication between the battery's BMS and the motherboard. SMBus Data (SDA)

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. | | 3 | System Management Bus Clock

Locate Pins 6 and 7 (usually the far right side when looking at the exposed slots).
