Power Rails: Pins 1, 2, 6, and 7 Hp Mu06 Notebook Battery Pinout Configuration
The HP MU06 is one of the most widely used laptop batteries in hardware history, powering generations of HP Pavilion, Compaq Presario, and Envy laptops. For hardware hackers, electronics hobbyists, and repair technicians, understanding the pinout configuration of this battery is essential for external charging, capacity testing, or DIY power projects.
Secure the battery flat on an anti-static mat. Locate Pin 1 (far left) and Pin 6/Pin 7 (far right). Understanding the pinout is fundamental for several tasks:
The HP MU06 battery interface consists of a female slot connector with . When looking directly at the battery's connector slot with the guide tabs facing upward, the pins are numbered from left to right (or right to left depending on orientation, but standard convention maps them relative to Positive and Ground). Here is the functional map of the 7-pin connector: Pin Number Signal Name Description Pin 1 (+) Plus / VCC Positive Power Output (10.8V - 11.1V) Pin 2 (+) Plus / VCC
The battery connects to the laptop motherboard via a male header. When looking at the battery connector with the contacts facing you and the locking tab at the top, the pins are generally arranged from left to right. The HP MU06 battery interface consists of a
While not 100% reliable due to variations between manufacturers, the wire colors inside the battery can serve as a secondary confirmation of the pin functions:
