Hp Mu06 Notebook Battery Pinout Configuration //top\\ -
| Pin Number | Label / Name | Description | Function | | :--- | :--- | :--- | :--- | | | 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). |
Pin 3 is a safety mechanism. In most HP architectures, the laptop will not turn on or attempt to charge the battery unless it detects that a valid pack is fully seated. Pin 3 is usually connected inside the battery to Ground through a small resistor (or directly). When the laptop detects this pin dropping to 0V, it knows a battery is present and activates the charging/discharging FETs. The "Zero Voltage" Phenomenon: Why You Might Measure 0V
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) Hp Mu06 Notebook Battery Pinout Configuration
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.
Understanding the pinout configuration of the HP MU06 battery is essential if you want to test its health externally, use it for DIY power projects, or diagnose charging issues. Overview of the HP MU06 Battery | Pin Number | Label / Name |
Are you trying to , or repurpose the battery for a DIY project?
The HP MU06 is one of the most ubiquitous laptop batteries ever produced, powering a massive range of HP Pavilion, Compaq Presario, and Envy models. For electronics enthusiasts, repair technicians, or those looking to repurpose these cells for DIY power projects, understanding the pinout is essential.
