Technical Breakdown: HP MU06 Notebook Battery Pinout Configuration

The HP MU06 is a widely used Li-ion battery model found in various HP Pavilion and Compaq Presario laptop series (typically the 6-cell, 10.8V/11.1V or 14.4V/14.8V variants). Understanding its pinout is essential for technicians attempting to revive dead batteries, repair motherboard charging circuits, or repurpose the cells for other electronic projects.

Typical MU06-style connector signals (left-to-right as seen on pack edge; orientation may vary by pack)

• +VBAT (pack positive output)
• SMBus Data (SDA / I2C)
• SMBus Clock (SCL / I2C)
• Thermistor / NTC sense (often two-wire or single-wire with pull)
• Pack ID / Manufacturer ID or Alert (chip-specific pin; sometimes used for presence)
• GND (pack negative / pack return)

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.

7. Conclusion

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.

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.

Communication: SMBus (System Management Bus) protocol, often managed by a or similar Texas Instruments impedance tracking gauge. Amazon.com Critical Troubleshooting Notes Safety Lock:

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:

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:

If the Windows battery percentage is inaccurate, HP recommends a full calibration cycle: charging to 100%, then running a "Loop until error" memory test in the HP PC Hardware Diagnostics UEFI until the battery is fully depleted. for this specific battery type? Laptop battery pinout configurations - EEVblog

The HP MU06 is a 6-cell Lithium-ion battery utilizing a 7 or 8-pin connector with a standard Smart Battery System (SBS) layout, commonly providing 11.1V and 47-58Wh capacity. Key terminals include V+ (1-2), GND (7-8), and data lines for SMBus communication (3-4), requiring the System Present pin (5) to be grounded for output activation.

Pin layout (left-to-right when the battery contact side faces you, contacts exposed upward):

• Pin 1 — SMBus SCL (battery management clock)
• Pin 2 — SMBus SDA (battery management data)
• Pin 3 — Thermistor / BAT_TEMP (NTC) — temperature sense line
• Pin 4 — Battery Pack ID / Manufacturer/Smart flag (sometimes tied to SMBus)
• Pin 5 — +Pack Voltage / Battery + (Pack positive)
• Pin 6 — N/C or Reserved (often unused or reserved for future signals)
• Pin 7 — Battery Pack ground / Battery - (Pack negative / chassis ground)
• Pin 8 — Wake/Enable or fuel-gauge interrupt (present on some revisions)

Common electrical characteristics and notes:

• Pack voltage: typically 11.1V nominal (3S Li-ion) or 14.8V (4S) depending on the MU06 revision — check the label on the pack.
• SMBus: uses SMBus/I2C-level signaling (usually 0–3.3 V logic). The system motherboard polls the fuel gauge.
• Thermistor: usually a 10 kΩ NTC at 25°C; used for charging thermal cutout and temperature reporting.
• Do NOT short Pack + to ground. Use proper battery management and safety equipment.
• Pin functions can be combined or omitted on some cheaper/remanufactured packs (e.g., no separate ID pin).
• Physical contact order and numbering can differ; confirm by tracing the battery PCB or measuring continuity between the pack negative and the laptop chassis before powering.

Suggested verification steps before connecting or repairing:

1. Inspect the pack label for nominal voltage and cell count (3S vs 4S).
2. With a multimeter, measure pack open-circuit voltage across the suspected + and - pins to confirm correct pins.
3. Measure resistor to ground on the thermistor pin at room temp to confirm ~10 kΩ (if present).
4. If needed, read SMBus with a proper SMBus/I2C adapter and safe current-limited supply — do not connect to an unknown host without current limiting.
5. When in doubt, consult the specific laptop or battery service manual or replace with a verified compatible pack.

  • Temperature (°C / °K)
  • Cycle count
  • Battery serial number, manufacturer, and design capacity
• Typical voltage: 3.3V (open-drain, pull-up required).

1. B+ (Pin 1)

• Direct connection to the battery cells' positive terminal (3 cells in series = 3S Li-ion).
• Voltage ranges: 11.4V (nominal) , 12.6V (fully charged) , ~9.0V (cutoff) .

Example SMBus registers commonly used (conceptual)

• Manufacturer name / Model
• Serial number
• Design capacity / Full charge capacity (FCC)
• Voltage / Current / Temperature
• State-of-charge (SoC)
• Cycle count / Pack status flags

(Exact register map depends on gauge IC; TI BQ family uses standard SBS/Smart Battery commands.)
