HP MU06 Notebook Battery Pinout Configuration: A Comprehensive Technical Guide
Are you trying to , or repurpose the battery for a DIY project?
Bridging Pin 1/2 directly to Pin 6/7 will bypass safety features and can cause thermal runaway, fire, or explosions.
The battery relies on an internal Smart Battery System (SBS) controller. This integrated circuit manages safety, reports state-of-charge data via standard communication protocols, and cuts off power if it detects a dangerous imbalance or over-current scenario. The MU06 Blade Connector Layout
| Pin # | Description | Voltage | | --- | --- | --- | | 1 | Negative (-) | 0V | | 2 | Positive (+) | 11.1V (or 14.8V for some models) | | 3 | Thermistor (NTC) | - | | 4 | ID (Identification) | - | | 5 | Clock (or Communication) | - | | 6 | Data (or Communication) | - |
Typically 6 cells (configured in 3S2P – 3 series, 2 parallel) Capacity: Generally 47Wh to 55Wh (4200mAh to 5200mAh) Communication Protocol: System Management Bus (SMBus) HP MU06 Pinout Configuration
If you are trying to power an external device, you can use the + and - pins, but you must ensure your device is compatible with 11.1V input.
protocol (Standard Battery System) for communication with the laptop's motherboard Orientation
What do you currently have on hand (e.g., multimeter, bench power supply, Arduino)?
The SMBD (Data) and SMBC (Clock) pins allow the battery's internal Texas Instruments (or similar) Fuel Gauge IC to talk to the laptop's Embedded Controller (EC). Through these lines, the laptop reads data such as: Remaining capacity percentage Current temperature of the cells Total cycle count Serial number and manufacturer data
Lithium-ion cells store significant amounts of energy. Never short-circuit Pins 1/2 directly to Pins 6/7. Doing so can cause immediate sparks, ruin the internal protective fuses, or induce thermal runaway, which presents a serious fire hazard.
are similarly tied together to handle the ground return path.Using dual blades splits the current load, keeping the contact points cool and reducing contact resistance. 2. The SMBus Communication Lines (Pins 3 and 4)
