Battery temperature sensor (Thermistor) or identification pin. NC / Mystery

Pins 4 and 5 handle the SMBus protocol. Through these lines, the laptop motherboard talks to the battery’s internal Texas Instruments (or similar) fuel gauge IC. The laptop reads critical telemetry over these pins, including: Current state of charge (percentage) Cycle count Absolute capacity vs. design capacity Internal temperature cell readings Manufacturer data and serial numbers 3. System Presence / Insertion Pin (BI / ID)

This HP battery pack typically has 6 or 7 contact pins, but not all are always populated on every model. Their functions are:

This happens because the internal BMS acts as an electronic switch. For safety reasons, the BMS disconnects the physical cells from the external pins if:

If you are trying to test an MU06 battery using a multimeter or want to repurpose it to power a custom robot or DIY project, follow these steps to safely activate the power output: Step 1: Identify the Ground and Positive Rails

Use a small jumper wire or a resistor (typically 10k ohms) to connect Pin 3 (SYS_PRES) directly to Pin 1 (GND). The laptop reads critical telemetry over these pins,

When it's time to purchase a replacement, the most reliable approach remains verifying the on your current battery. Third-party sellers will list these numbers, ensuring compatibility even without a pinout diagram. When handling any lithium-ion battery, prioritize safety and treat it with the respect it deserves.

For hardware hackers, electronics hobbyists, and repair technicians, repurposing or diagnosing this battery requires an exact understanding of its connector pins. HP smart batteries do not simply output raw voltage; they rely on a System Management Bus (SMBus) protocol to communicate with the host laptop or external chargers. Technical Specifications of the HP MU06

The HP MU06 is one of the most widely used laptop batteries in hardware history. It powers massive line-ups of legacy Hewlett-Packard laptops, including the Pavilion, Envy, G-series, and Compaq Presario models. Their functions are: Do you need assistance using

typically features a configuration . While HP does not always provide an official public pinout diagram, community data and technical teardowns indicate the standard layout used for these SMBus-based batteries. Standard HP MU06 Pinout (9-Pin Layout)

Working with lithium-ion batteries carries inherent risks. Please consider the following:

The HP MU06 is a smart lithium-ion battery (typically 3-cell, 41 Wh) used in modern HP consumer laptops. Unlike older batteries with simple positive/negative terminals, the MU06 uses a multi-pin interface for communication, balancing, and safety. Understanding its pinout is critical for:

Through these lines, the laptop reads the battery’s internal telemetry, including the absolute state of charge, cycle count, manufacturer date, current temperature, and individual cell bank voltages. 3. The System Present Detect / CID Pin (Pin 5)
