Hp Mu06: Notebook Battery Pinout Configuration
The battery connects to the laptop motherboard via a male header. When looking at the battery connector with the contacts facing you and the locking tab at the top, the pins are generally arranged from left to right.
Connects to Ground (Pin 1/2) to tell the laptop the battery is inserted. Clock (C) SM Bus clock line. 6 Data (D) SM Bus data line. 7 Positive (+) Positive terminal, typically 10.8V or 11.1V. 8 Positive (+) Positive terminal, typically 10.8V or 11.1V. Key Pins Explained
Working with lithium-ion batteries requires strict adherence to safety protocols. The HP MU06 battery contains cells that can release significant energy if short-circuited or physically damaged. Always observe these precautions:
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. Hp Mu06 Notebook Battery Pinout Configuration
Multiple wires of the same color (e.g., 3 red and 3 black) are often used in parallel for the main power path. This is a standard engineering practice to safely handle higher currents, reduce electrical resistance, and provide redundancy. In terms of the pinout, all red wires are electrically the same point ( B+ ), and all black wires are the same point ( B- ).
| Pin | Label (Common) | Wire Color (Typical) | Function | | :--- | :--- | :--- | :--- | | 1 | P- (B-) | Black | Battery Negative / Ground | | 2 | P- (B-) | Black | Battery Negative / Ground | | 3 | SMBC | White or Yellow | SMBus Clock (I²C Clock) | | 4 | SMBD | White or Yellow | SMBus Data (I²C Data) | | 5 | PRES | Blue or Orange | Presence Detect / System Present | | 6 | P+ (B+) | Red | Battery Positive (11.55V – 12.6V) | | 7 | P+ (B+) | Red | Battery Positive (11.55V – 12.6V) |
. While HP does not officially publish pinout diagrams for end-users, technical teardowns and repair communities have identified the following configuration: Pinout Configuration (9-Pin Layout) The battery connects to the laptop motherboard via
While you could theoretically map the pins from the new battery to match your laptop's connector using the pinout principles above, HP laptops have a "vendor lock" security check. Even if the physical pinout is correct, the laptop's BIOS may reject the battery's electronic ID, preventing it from charging. Modifying the BMS firmware to bypass this is an extremely advanced task that requires specialized hardware like an EV2400 programmer.
Synchronizes data transmission between the laptop and the battery.
You cannot simply apply 11V to pins 1 and 7. Modern Li-ion batteries require a CC/CV (Constant Current/Constant Voltage) charging profile managed by an external controller or the laptop’s internal charging IC. Identifying Your MU06 Battery Clock (C) SM Bus clock line

In this configuration, Pins 1 and 2 are both connected to the battery’s negative terminal (ground). Pins 7 and 8 are both connected to the battery’s positive terminal (VCC), providing dual contacts for improved current-carrying capacity. Pin 3 carries temperature sensor information, allowing the laptop to monitor the battery’s thermal condition. Pin 4 is a battery identification (BatID) line, which typically uses a resistor network to identify the specific battery model, enabling the laptop’s charging controller to apply the correct charging algorithm.
