Hp Mu06 Notebook Battery Pinout Configuration May 2026

The battery uses a 7-pin (2.0mm pitch) wafer-type connector. Pins are numbered from left to right when looking at the battery label side with the connector facing you.

| Parameter | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | | P+ to P- voltage (operating) | 9.0 | 11.55 | 12.6 | V | | P+ to P- voltage (protection trip) | 4.2 (per cell under) | – | 4.35 (per cell over) | V | | SMBus logic low (VIL) | – | – | 0.8 | V | | SMBus logic high (VIH) | 2.1 | 3.3 | 3.6 | V | | SMBus clock frequency | – | 100 | 400 | kHz | | PRES pin impedance (active) | – | 10 | 50 | Ω to GND |

The MU06 uses a 9-pin (sometimes 7 populated) flat ribbon cable connector, often JST or Molex compatible.
Common label on PCB: MU06 or HSTNN-LB7N. Hp Mu06 Notebook Battery Pinout Configuration

Below is the standard pinout configuration for the HP MU06 battery circuit.

| Pin Number | Label / Name | Description | Function | | :--- | :--- | :--- | :--- | | 1 | PACK+ | Positive Terminal | Main positive voltage output. Connects to the positive end of the cell array. | | 2 | PACK+ | Positive Terminal | Main positive voltage output (often bridged to Pin 1 for higher current handling). | | 3 | ID / TH | Thermistor / ID | Connects to an internal NTC thermistor. Used by the laptop to monitor battery temperature. Often serves a dual purpose as a security ID line. | | 4 | CLK | Clock (SCL) | I²C Serial Clock line. Used for SMBus communication between the battery BMS and the laptop EC (Embedded Controller). | | 5 | DATA | Data (SDA) | I²C Serial Data line. Transmits capacity, cycle count, and voltage data to the OS. | | 6 | SYS PRES | System Present | Often a logic signal indicating the battery is fully inserted. Usually pulled low or high depending on the circuit design. | | 7 | NC / ALM | No Connect / Alarm | Often unused (NC) or used for safety alerts. Can be a secondary temperature sensor in some revisions. | | 8 | PACK- | Negative Terminal | Main ground/negative output. Connects to the negative end of the cell array. | | 9 | PACK- | Negative Terminal | Main ground/negative output (bridged to Pin 8). | The battery uses a 7-pin (2

Note: Some 9-pin revisions swap Pin 6 and 7 functions. Always verify continuity between negative pins and the cell negative terminal to identify ground.

⚠️ Critical Warning: Laptop batteries operate at ~11.55V to 12.6V and can deliver high current. Do not short pins. Use a multimeter, not trial and error. Typical voltage: 3

The HP MU06 is a 3-cell Lithium-Ion (Li-Ion) prismatic battery pack designed for mid-range HP consumer laptops. It operates on a Smart Battery System (SBS) compliant architecture, utilizing an I²C communication bus for data transfer between the battery management system (BMS) and the laptop’s EC (Embedded Controller).
