This is a safety logic pin. The laptop motherboard features a pull-up resistor on this line. When the battery is fully seated, Pin 3 bridges to ground inside the battery pack. This signals the laptop's power management IC (PMIC) that a battery is physically present, enabling the main power rails.
The HP MU06 notebook battery pinout configuration typically consists of multiple pins, which vary depending on the specific battery model and laptop design. However, based on common configurations, here's a general overview of the HP MU06 notebook battery pinout:
The HP MU06 notebook battery pinout follows a standard 7-pin layout with dual ground, dual positive, SMBus clock/data, and a thermistor sense line. The critical takeaway is that the battery does not output power until authenticated by the laptop via SMBus – a security feature to prevent third-party or damaged batteries from operating.
Lithium-ion cells store significant amounts of energy. Never short-circuit Pins 1/2 directly to Pins 6/7. Doing so can cause immediate sparks, ruin the internal protective fuses, or induce thermal runaway, which presents a serious fire hazard. Hp Mu06 Notebook Battery Pinout Configuration

For advanced users, you can read SMBus registers (e.g., 0x09 – Voltage, 0x0D – Remaining Capacity) using a USB-to-SMBus adapter (Arduino with SMBus library or Adafruit FT232H).
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 is a safety logic pin
Never attempt to charge an MU06 battery by directly hooking up a dumb 12V power supply to Pins 1 and 7. Without the proper SMBus handshake and a dedicated smart charger that monitors cell balance, the battery can overheat, swell, or catch fire.
Working directly with the raw pinouts of lithium-ion notebook batteries carries inherent risks.
The HP MU06 battery utilizes a standardized . When looking directly at the male slot connector on the battery pack with the plastic guide rails facing upwards, the pins are counted from left to right. This signals the laptop's power management IC (PMIC)
To test an HP MU06 battery, you will need a digital multimeter (DMM) set to DC voltage.
This HP battery pack typically has 6 or 7 contact pins, but not all are always populated on every model. Their functions are:
– Delivers the main 10.8V to 11.1V DC output to the laptop.
Before analyzing the pinout, it is important to understand the internal architecture and ratings of the battery pack. The HP MU06 is typically a 6-cell Lithium-Ion battery pack configured in a 3S2P (3 cells in series, 2 packages in parallel) design.
: Some HP batteries require the "System Present" pin (often Pin 5) to be pulled to Ground (GND) before the internal protection circuit (MOSFETs) will allow power to flow to the main positive terminals. MU06 Battery Specifications : Lithium-Ion (Li-ion).
