The HP MU06 notebook battery is one of the most common power cells for legacy HP Pavilion, Compaq Presario, and Envy series laptops. Understanding its pinout configuration is critical for technical diagnostics, DIY external charging, or battery repair projects. HP MU06 Battery Technical Specifications
Before diving into the pinout, it is essential to identify the battery's electrical properties. The MU06 is typically a 6-cell Lithium-ion battery with the following ratings: Voltage: 10.8V (compatible with 11.1V systems) Capacity: Ranges from 4200mAh to 5200mAh (47Wh to 56Wh)
Primary Part Numbers: 593553-001, 593554-001, MU06, MU09, HSTNN-LB0W
Compatible Laptops: HP Pavilion G4, G6, G7, DV6, DV7; Compaq Presario CQ42, CQ56, CQ62 Detailed Pinout Configuration
While HP does not publicly document these pinouts for consumers, technical analysis from battery repair communities and analyzer tools provides a standardized configuration for the MU06's physical connector. hp mu06 notebook battery pinout configuration link
The MU06 typically features a 6-pin or 7-pin linear connector, though some specialized versions may use an 8-pin layout. The standard sequence (viewed from left to right with the label facing up) is as follows: [Solved] HP smart storage pinout - NIP Embedded Systems
Below is the verified pinout for the HP MU06 9-pin variant. This is based on direct measurements and service manual cross-references for HP TPN-Q188 motherboards.
| Pin | Signal Name | Function | Typical Wire Color | |-----|---------------|---------------------------------------------------|--------------------| | 1 | B+ (Battery+) | Main positive terminal (8.4V – 12.6V, nominal 11.4V) | Red or Black | | 2 | B+ (Battery+) | Same as Pin 1 (current sharing) | Red or Black | | 3 | SCL | SMBus Clock Line (3.3V logic, 100 kHz) | White or Gray | | 4 | SDA | SMBus Data Line (3.3V logic) | Yellow or Blue | | 5 | SMBD_ALERT# | Battery alert (interrupt to EC) - open drain | Green or Orange | | 6 | PRES (or ID) | Battery presence detection (pulled low inside battery) | Brown | | 7 | THERM | Thermistor output (10k NTC to ground, ~1.5V at 25°C) | Violet | | 8 | B- (Ground) | Main negative terminal (0V) | Black (thick) | | 9 | B- (Ground) | Same as Pin 8 (current return) | Black (thick) |
Note for 11-pin versions:
Pins 10 and 11 are often not connected (NC) or used as additional presence detection. If your battery has 11 pins, ignore the extra pins – the first 9 pins match the above table. The HP MU06 notebook battery is one of
Before soldering or probing, measure resistance between Pin 6 (PRES) and Pin 8 (B-). A healthy battery will show near 0 ohms (internal pull-down). If it shows open circuit, the BMS may have permanently disconnected due to over-discharge protection.
