The battery uses a 7-pin (2.0mm pitch) wafer-type connector. Pins are numbered from left to right when looking at the battery label side with the connector facing you.
| Pin | Signal Name | Function | Typical Voltage/Logic | |-----|--------------------|--------------------------------------------------------------------------|-------------------------------------| | 1 | B+ | Battery positive terminal (cell series output) | 10.8V – 12.6V (3S Li-ion) | | 2 | B+ (sense) | Redundant positive sense line (for voltage drop compensation) | Same as B+ | | 3 | SMBC | SMBus clock line (I²C-compatible) | 3.3V pull-up, bi-directional | | 4 | SMBD | SMBus data line | 3.3V pull-up, bi-directional | | 5 | TH / T | Temperature sensor (NTC thermistor, 10kΩ at 25°C) | ~0.5–2.5V depending on temp | | 6 | NC or ID | Not connected (or battery ID resistor for charger detection) | 4.7kΩ – 10kΩ to ground | | 7 | B- / GND | Battery ground | 0V | | 8 | B- / GND | Second ground (current return for high power) | 0V | | 9 | B- / GND | Third ground (safety/redundancy) | 0V |
Note: Some MU06 variants may swap pin 5 and 6, or omit pin 6. Always verify with a multimeter before connecting.
The HP MU06 battery follows a standard 7-pin SMBus configuration where Pins 1,2 = Ground; Pins 6,7 = Positive; Pin 5 = Presence Detect; Pins 3,4 = SMBus Clock/Data. The BMS implements strict safety and lockout features. Unauthorized cell replacement or improper voltage application on the SMBus lines will likely trigger a permanent failure lock. For reverse engineering or repair, always use an isolated SMBus adapter and monitor cell balance before attempting to reset the BMS.

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
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.
The HP MU06 Notebook Battery is a ubiquitous 6-cell Lithium-Ion power pack used in a wide range of HP G-series, Pavilion, and Compaq Presario laptops. Understanding its pinout configuration is essential for advanced troubleshooting, external charging, or battery "resetting" using professional tools like the NLBA1 Laptop Battery Analyzer. Pinout Configuration Table
The MU06 battery connector typically features 7 to 9 pins (depending on the specific revision), though the standard interface relies on five primary functional lines. When looking at the battery connector with the pins facing you, the configuration is generally as follows: Pin Number Description Pin 1 & 2 Ground (GND)
Negative terminals, often bridged for higher current capacity. Pin 3 SMBus Clock (SCL) Communication line for the battery management system (BMS). Pin 4 SMBus Data (SDA)
Data line used to transmit health and capacity stats to the OS. Pin 5 System Present
A safety pin that must be pulled to ground to enable voltage output. Pin 6 Thermistor (T) Temperature sensing pin for thermal safety monitoring. Pin 7, 8, 9 Positive (+) Main voltage output (typically 10.8V to 11.1V). Key Components and Technical Details

Identification & Testing Tips
If your specific MU06 variant differs (some use a compact 7-pin layout), you can verify the pins using these methods:
Voltage Testing: Use a multimeter to find the outer pins. The pair showing roughly 10.8V - 11.1V is the Positive (+), while the opposite end with zero resistance to the case is Ground (-).
Communication Pins: The SMBus pins (Clock and Data) will typically show a logic-level voltage (often 3.3V) when the battery is active or connected to a charger.
Official Documentation: For specific part number variants, you can check for setup guides on the HP Support site.
Technical Discussions: For deeper troubleshooting or signal analysis, many users reference community guides on sites like EEVblog or KuzyaTech. Common Compatibility
The MU06 pinout is consistent across several HP and Compaq series, including: HP Pavilion: G4, G6, G7, DV6, DV7. Compaq Presario: CQ32, CQ42, CQ62. HP 2000 Series: Notebook PCs.

The main power output pins; often tied together to handle current. Critical Technical Insights
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

If you are working with a third-party variant or need to verify your specific unit, follow these steps:
Locate Ground and Power: Use a multimeter to find the pins with the largest blades. These are almost always at the extreme ends of the connector. On the MU06, the leftmost two pins (1, 2) are typically Ground, and the rightmost two (8, 9) are Positive.
Test Communication Lines: The communication pins (Clock and Data) are usually found on pins 3 and 4. These pins often have ESD protection diodes. You can identify them by measuring resistance to Ground; you should see a similar value (around 600–800mV in diode mode) on both.
Check for "System Present": If the battery shows 0V at the main terminals despite being charged, Pin 6 or 7 may need to be bridged to Ground (Pin 1/2) to "wake up" the battery's internal BMS.
Confirm Orientation: Look for the small plastic notches on the connector. On some HP models, Pin #1 is indicated on the motherboard next to the socket. Key Technical Specs Voltage: 10.8V or 11.1V (compatible). Capacity: Typically 47Wh to 52Wh (4400mAh – 5200mAh)
