Hp Mu06 Notebook Battery Pinout Configuration Guide

Technical Review: HP MU06 Notebook Battery Pinout Configuration

1. Overview

The HP MU06 is a smart lithium-ion battery (typically 3-cell, 41 Wh) used in modern HP consumer laptops. Unlike older batteries with simple positive/negative terminals, the MU06 uses a multi-pin interface for communication, balancing, and safety. Understanding its pinout is critical for:

: Some HP batteries require the "System Present" pin (often Pin 5) to be pulled to Ground (GND) before the internal protection circuit (MOSFETs) will allow power to flow to the main positive terminals.

• Pin 1: VBATT (Battery Voltage) - This pin carries the battery voltage, typically ranging from 10.8V to 14.8V.
• Pin 2: GND (Ground) - This pin provides a ground connection for the battery.
• Pin 3: TX (Transmit) - This pin transmits data from the battery to the laptop, such as battery level, temperature, and other status information.
• Pin 4: RX (Receive) - This pin receives data from the laptop, such as charging commands or battery calibration data.
• Pin 5: ID (Identification) - This pin carries the battery's identification information, such as the battery type, capacity, and manufacturer.
• Pin 6: TEMP (Temperature) - This pin provides temperature data from the battery to the laptop.
• Pin 7: CHG (Charge) - This pin controls the charging process, allowing the laptop to regulate the flow of energy to the battery.
• Pin 8: PROTECT (Protection) - This pin enables protection features, such as overcharge protection, over-discharge protection, and short-circuit protection.
