Carries digital data (charge level, cycle count, temperature) to the laptop. System Present / Temp
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
If you are trying to test or reuse an HP MU06 pack outside of a laptop, keep these rules in mind: Reading Voltage
The communication is handled by a specialized "fuel gauge" or "battery management" chip. For the MU06, this chip has been identified as the or BQ20Z40 chip. The BQ20Zxx series uses the Texas Instruments Impedance Track™ technology for accurate battery monitoring and also handles safety functions like overvoltage and overcurrent protection. Hp Mu06 Notebook Battery Pinout Configuration
Never attempt to charge the pack by forcing raw DC voltage into the power pins without current limitations. Safe charging requires a CC/CV (Constant Current/Constant Voltage) profile matching the 3S configuration limits (Max 12.6V charging voltage).
The HP MU06 battery utilizes a wafer connector. When looking at the battery’s own connector (with the locking latch facing up or away from you, and the wires leading into the battery pack), the pin numbering is typically from left (Pin 1) to right (Pin 7).
This guide provides a comprehensive breakdown of the HP MU06 notebook battery pinout configuration, its smart battery interface, and safety protocols. Hardware Specifications Overview For the MU06, this chip has been identified
The SMBus lines (SCL and SDA) are open-drain. To read data, you must connect a 4.7kΩ to 10kΩ pull-up resistor from the SCL and SDA lines to a 3.3V power source provided by your microcontroller or bus master.
HP MU06 notebook battery generally utilizes a 9-pin blade-style connector
Let’s examine what each pin does inside the HP MU06 battery system. its smart battery interface
The HP MU06 is a widely used rechargeable lithium-ion (Li-ion) battery pack, primarily designed for a vast range of HP Pavilion, Compaq Presario, and Envy series laptops produced from around 2010 to 2015. It is a that supplies a nominal voltage of 10.8V to 11.1V, with typical capacities ranging from 4400mAh (around 47Wh) to 5200mAh (around 56Wh).
The HP MU06 is one of the most widely used laptop battery models in hardware history. It powers hundreds of laptop models across the HP Pavilion, Envy, G-series, and Compaq Presario lines released during the early to mid-2010s.
