HP MU06 notebook battery generally utilizes a 9-pin blade-style connector
integrated into its plastic housing. While HP does not officially publish pinout diagrams for consumer repairs, technical analysis of MU06-compatible batteries identifies the following configuration: Store Shoppe Pinout Configuration Table Typically, the pins are numbered from left to right
when looking at the battery with the connector facing you and the label side up. Description Ground (GND)
The leftmost two pins are connected to the negative terminal of the battery pack. SMBus Clock (SCL)
Used for I2C/SMBus communication between the battery's BMS and the motherboard. SMBus Data (SDA)
Carries digital data (charge level, cycle count, temperature) to the laptop. System Present / Temp
Often serves as a temperature sensor (Thermistor) or a "System Present" pin that must be grounded to enable output. Reserved/ID
These pins are often unused or provide specific battery identification signals. Battery Positive (V+)
The rightmost two pins provide the main voltage output (typically 10.8V or 11.1V). Technical Identification Tips Visual Indicators : Check the battery casing for molded "+" and "-" signs
. Ground is usually the set of pins nearest the "-" sign, while V+ is near the "+". Safety Features : The MU06 utilizes an SMBus protocol
for communication. If the clock (SCL) or data (SDA) pins are not communicating properly, the laptop may fail to detect or charge the battery even if physical contact is made. Activation
: 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).
: Standard packs are 10.8V or 11.1V (depending on cell configuration).

Smart batteries like the MU06 may "lock" or shut down their MOSFETs if they detect a critical imbalance or deep discharge (below ~3V per cell). In this state, no voltage will be measured at the V+ pins even if the cells are physically healthy. Replacement Packs: Hp Mu06 Notebook Battery Pinout Configuration
Some third-party replacement batteries may have slightly different internal wiring for the "System Present" pin, which can prevent charging if the laptop doesn't recognize the "low" signal on Pin 6. Calibration:

System Present Pin (Pin 6): If you are testing this battery outside of a laptop, you may need to connect Pin 6 to Ground (Pin 1/2) to "wake up" the battery and see voltage on the positive pins. Safety Lock : Most MU06 batteries use Texas Instruments BQ20Z45
or BQ20Z40 chips. If the battery cells are deeply discharged (below ~3.0V), the BMS may enter a "Permanent Failure" (PF) state, which requires specialized software like the NLBA PC Software or a TI EV2300/2400 to reset.
Pin Orientation: When looking at the battery connector facing up (as it sits in the laptop), Pin 1 is usually on the left and Pin 9 on the right. Laptop battery pinout configurations - EEVblog
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. HP MU06 Notebook Battery Pinout Configuration HP MU06 notebook battery generally utilizes a 9-pin
The MU06 battery typically utilizes a 7-pin connector interface. While the plastic casing may vary slightly between manufacturers, the internal electrical standard remains consistent to ensure compatibility with the HP motherboard’s SMbus (System Management Bus) protocol. Pinout Mapping (Standard 7-Pin Layout)
Counting from left to right (with the battery label facing up and the connector facing you):
Pin 1: Positive (+) Terminal – Delivers the main 10.8V to 11.1V DC output to the laptop.
Pin 2: Positive (+) Terminal – A redundant pin for the main power rail to handle higher current.
Pin 3: SMbus Clock (C) – The timing signal for communication between the battery chip and the BIOS.
Pin 4: SMbus Data (D) – The serial data line used to report charge level, temperature, and cycle count.
Pin 5: Thermistor (T) / System Present – Monitors internal cell temperature; often pulled to ground to signal the battery is "inserted."
Pin 6: Negative (-) Terminal – The common ground (GND) for the battery pack.
Pin 7: Negative (-) Terminal – A redundant ground pin to minimize electrical resistance. Technical Specifications and Internals
Understanding the configuration requires looking at what is happening inside the plastic shell. Voltage: 10.8V (Standard) or 11.1V (High Capacity). Cell Chemistry: Lithium-Ion (Li-ion).
Configuration: Typically a 3S2P layout (3 cells in series, 2 in parallel) using 18650 cells.
Capacity: Ranges from 4400mAh to 5200mAh for standard 6-cell versions. Critical Safety Warnings for DIY Projects
If you are attempting to jump-start a "dead" MU06 or use it as a standalone power source, keep the following in mind:
Logic Protection: Most MU06 batteries contain a "Smart Battery" circuit. If the voltage drops below a certain threshold (usually 2.5V per cell), the internal MOSFETs will permanently "brick" the battery for safety.
Short Circuit Risk: Pins 1/2 and 6/7 are very close together. Use insulated probes to prevent a high-current short.
Charging Requirements: You cannot simply apply 11V to pins 1 and 7. Modern Li-ion batteries require a CC/CV (Constant Current/Constant Voltage) charging profile managed by an external controller or the laptop’s internal charging IC. Identifying Your MU06 Battery
The MU06 is compatible with a wide array of HP part numbers. If your battery matches any of the following, the pinout configuration above applies: 593553-001 593554-001 HSTNN-LB0W HSTNN-CBOX
💡 Pro Tip: If you are testing for voltage with a multimeter and get 0V across the outer pins, the internal protection circuit is likely engaged. You may need to apply a small "wake-up" voltage (around 9V) briefly to see if the BMS (Battery Management System) resets.
Understanding the pinout configuration of the HP MU06 notebook battery is essential for tasks like external charging, cell replacement, or resetting the internal battery management system (BMS). This common 6-cell battery is used in a wide range of HP Pavilion, Compaq, and Envy models. Pinout Configuration Overview Physical Connector Identification
The MU06 battery typically utilizes an 8-pin connector. While official HP documentation rarely provides pinouts for consumer-level repair, community data and electrical testing define the standard 8-pin layout as follows: Pin 1: Ground (Negative / -) Pin 2: Ground (Negative / -) (Doubled for current handling) Pin 3: Unknown / NC (Often no connection)
Pin 4: System Present / ID (Sometimes needs to be pulled to ground to enable output) Pin 5: Clock (SCL) (SMBus/I2C communication) Pin 6: Data (SDA) (SMBus/I2C communication) Pin 7: Positive (V+ / +) (Output voltage) Pin 8: Positive (V+ / +) (Output voltage)
Note: On some variations, the numbering may be reversed depending on the orientation of the connector (left-to-right vs. right-to-left). Always use a multimeter to verify Ground (which will show 0 ohms to the battery's negative terminal) and Positive pins before applying power. Technical Specifications Battery Type: Lithium-ion (Li-ion)
Standard Voltage: 10.8V or 11.1V (depending on cell configuration) Capacity: Typically 47Wh to 55Wh for 6-cell versions
Chipset: Often uses the BQ20ZXX family (e.g., BQ20Z40), which utilizes the SMBus protocol for impedance tracking and state-of-charge calculation. Critical Maintenance Tips
Safety First: Lithium-ion batteries can be dangerous if short-circuited. Use insulated tools and avoid bridging the Positive and Ground pins.
Reprogramming: If you replace the cells, the BMS often locks the battery (Full Charge Capacity may appear as 0). Resetting this requires an EV2300/EV2400 adapter and specific software like BQEvsw to clear Permanent Failure (PF) bits.
Calibration: If your laptop shows incorrect percentages, you can perform a manual calibration by fully charging the battery, then discharging it completely through the HP PC Hardware Diagnostics (accessible via F2 at startup).
