Because laptop components can draw significant current during peak performance, the MU06 uses paired pins for the primary power rails.
(Note: Pin arrangements can vary slightly depending on the specific OEM manufacturer of the battery cell, e.g., Samsung, LG, or Sanyo cells inside the HP casing. Always verify with a multimeter if possible.)
These are vital for the "smart" functionality. Without these, the laptop may not recognize the battery, or charging will not begin. Hp Mu06 Notebook Battery Pinout Configuration
Often serves as a temperature sensor (Thermistor) or a "System Present" pin that must be grounded to enable output. Reserved/ID
While not 100% reliable due to variations between manufacturers, the wire colors inside the battery can serve as a secondary confirmation of the pin functions: Without these, the laptop may not recognize the
The leftmost two pins are connected to the negative terminal of the battery pack. SMBus Clock (SCL)
It’s easy to confuse the MU06 with similar HP batteries: SMBus Clock (SCL) It’s easy to confuse the
Here is the standard structural configuration for the 7-pin interface: Pin Number Signal Name Description GND System Ground / Negative Terminal (-) Pin 2 GND System Ground / Secondary Negative Terminal Pin 3 BI / System Present Battery Insertion Detection (Pull-down to GND) Pin 4 SCL SMBus Clock Line (I2C communication clock) Pin 5 SDA SMBus Data Line (I2C communication data) Pin 6 V+ (Plus) Positive Battery Terminal / Charge-Discharge (+) Pin 7 V+ (Plus) Secondary Positive Battery Terminal (+) Detailed Pin Functionality
Add from both the SCL and SDA lines to a 3.3V or 5V power source, as the open-drain architecture of the communication lines requires external pull-ups to cleanly register data pulses. Safety Warning
Here is the standard 7-pin layout configuration for the HP MU06: Pin Number Description (+) Positive / VCC Main positive power output (approx. 10.8V - 12.6V) Pin 2 (+) Positive / VCC
