Hp Mu06 Notebook Battery Pinout Configuration May 2026
| Parameter | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | | P+ to P- voltage (operating) | 9.0 | 11.55 | 12.6 | V | | P+ to P- voltage (protection trip) | 4.2 (per cell under) | – | 4.35 (per cell over) | V | | SMBus logic low (VIL) | – | – | 0.8 | V | | SMBus logic high (VIH) | 2.1 | 3.3 | 3.6 | V | | SMBus clock frequency | – | 100 | 400 | kHz | | PRES pin impedance (active) | – | 10 | 50 | Ω to GND |
Using a multimeter (set to DC Volts, 20V range), measure between:
| Measurement Points | Expected Voltage (Standalone) | Expected Voltage (In Laptop, AC Present) | |----------------------|-------------------------------|-------------------------------------------| | Pin 6 to Pin 1 | 0V (FETs open) or 10.8–12.6V (rare if not locked) | 11–13V (charging) / 9–12V (discharging) | | Pin 3 (SMBC) to GND | 0V (no pull-up) | 3.3V | | Pin 4 (SMBD) to GND | 0V | 3.3V fluctuating (data activity) | | Pin 5 (TH) to GND | 10 kΩ to 100 kΩ (resistance) | 0.5V–2.5V (depending on temperature) |
Warning: Do not short Pin 6/7 to Pin 1/2 when the battery is not connected to the laptop. The protection circuit may permanently blow an internal fuse (often a 10A–15A SMD fuse).
The HP MU06 notebook battery pinout follows a standard 7-pin layout with dual ground, dual positive, SMBus clock/data, and a thermistor sense line. The critical takeaway is that the battery does not output power until authenticated by the laptop via SMBus – a security feature to prevent third-party or damaged batteries from operating.
Whether you are a repair technician trying to revive a locked BMS, a hobbyist building an external charger, or simply diagnosing a “battery not detected” error, always respect the pin functions and safety limits. Use an oscilloscope or multimeter with care, and when in doubt, replace the battery rather than risk fire or motherboard damage.
For further study, download the datasheet of the Texas Instruments BQ40Z50-R1 – it is the most common fuel gauge inside HP MU06 batteries and will give you full register mapping and pinout of the internal PCB.

typically features a 7-pin or 9-pin connector configuration. While HP does not always provide an official public pinout diagram, community data and technical teardowns indicate the standard layout used for these SMBus-based batteries. Standard HP MU06 Pinout (9-Pin Layout)
In many MU06 models, the connector uses 9 physical slots. For identification, hold the battery with the connector facing you and the label side up. The pins are generally numbered from left to right. Pin Number Description 1 - 2 Ground (-) Negative terminal/system ground. 3 SMBus Data (SDA) Communication line for battery data. 4 SMBus Clock (SCL) Timing line for data transfer. 5 Temperature (T) Thermistor pin to monitor battery heat. 6 System Present Often needs to be pulled to ground to enable the battery. 7 NC / Reserved Not connected or reserved for internal testing. 8 - 9 Positive (+) Main power output (typically 10.8V to 11.1V). 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. | Parameter | Min | Typ | Max
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.
Are you planning to rebuild the battery pack or use it for a DIY project?
The HP MU06 notebook battery is a widely used 6-cell Lithium-ion battery compatible with a vast range of HP Pavilion, Compaq Presario, and Envy series laptops. For technical users, understanding its pinout is essential for troubleshooting charging issues or performing battery resets. HP MU06 Pinout Configuration
The MU06 typically utilizes a 7-pin or 8-pin connector (depending on the specific sub-model/revision), commonly featuring a 2.5mm pitch blade-type interface. While HP does not officially document pinouts for end-users, community analysis and technician logs identify the standard configuration as follows:
Pin 1 & 2 (Negative / Ground): Connected to the negative terminal of the cell string.
Pin 3 & 4 (Communication - SMBus): Used for data exchange between the battery's internal gas gauge (often a BQ20Z40 or BQ20Z45 chip) and the laptop motherboard. SCL (Clock): Pin 3 SDA (Data): Pin 4 The HP MU06 notebook battery pinout follows a
Pin 5 (System Present / Control): A "jumper" or "ID" pin that tells the laptop a battery is physically inserted.
Pin 7 & 8 (Positive / V+): Connected to the positive terminal, typically delivering 10.8V to 11.1V. Technical Review: Performance & Reliability
Based on user experiences and technical specifications from Amazon and HP Support:
Disclaimer: Pinout configurations can vary slightly based on the exact OEM revision (e.g., Simplo vs. Dynapack). Always verify with a multimeter before connecting custom hardware.
(Exact register map depends on gauge IC; TI BQ family uses standard SBS/Smart Battery commands.)
The MU06 is an HP "Long Life" Li-ion battery pack built from series/parallel cell groups plus a battery management/controller (SMBus/Coulomb gauge). The external contact block exposes power terminals and a small SMBus/ID/status interface used by the laptop to read battery state, enable/disable output, and negotiate charging. There is no universal single pinout diagram published by HP for DIY repair; however MU06-compatible packs follow the common HP battery connector conventions below.
