Do you have a or an Arduino/microcontroller on hand to take readings?
The internal BMS has tripped a permanent failure flag (UVLO - Under-Voltage Lockout) due to dead cells or a short circuit. The pack is dead and unsafe to use. Safety Guidelines and Warning
These pins connect directly to the internal Battery Management System (BMS) microcontroller (often a Texas Instruments bq-series chip). Through the SCL (Clock) and SDA (Data) lines, the laptop reads critical smart data, including current capacity, cycle count, temperature, health status, and manufacture date. Hp Mu06 Notebook Battery Pinout Configuration
Note: some MU06 variants use 6 contacts, others 7; contact order and presence of dedicated temperature or sense pins varies by model and laptop family. The common essentials are VBAT+, GND, and SMBus SDA/SCL. The pack’s controller sits between the cells and VBAT output and can open MOSFETs to disconnect the pack.
The HP MU06 notebook battery, commonly used in Pavilion G6 and DV6 series, features a 9-pin interface requiring Pin 6 (System Present) to be grounded for voltage output. Key pins include GND (1,2), SMBus Clock/Data (3,4), and VBAT+ (8,9), which can be tested for 10.8V–12.6V using a multimeter, as described at Kuzyatech . AI responses may include mistakes.

The pins are typically numbered from left to right when looking at the battery’s connector face. Description Ground (GND) Main negative power terminal. Ground (GND) Parallel negative power terminal for high current. SMBus Clock (C) Synchronous clock line for battery communication. SMBus Data (D) Data line for reporting capacity, cycles, and temperature. Temperature (T) Thermistor pin for battery temperature sensing. System Present
For the standard MU06 layout, the orientation moves from the primary positive voltage supply to the system ground.

The HP MU06 is one of the most widely used laptop battery models in HP's history. It powers massive lineups of legacy laptops, including the HP Pavilion, Compaq Presario, and HP Envy series. For electronics hobbyists, repair technicians, and DIYers, understanding the pinout configuration of this battery is essential for testing, cell replacement, or repurposing the lithium-ion pack for external projects.
