Hp Mu06 Notebook Battery Pinout Configuration __full__ ❲iPad❳
The HP MU06 is one of the most ubiquitous laptop batteries ever produced, powering a massive range of HP Pavilion, Compaq Presario, and Envy models. For electronics enthusiasts, repair technicians, or those looking to repurpose these cells for DIY power projects, understanding the pinout is essential. HP MU06 Notebook Battery Pinout Configuration

Rating: ⭐⭐⭐⭐☆ (4/5)
Clear once documented, but confusing due to multiple GND pins and undocumented ID resistor variations across HP models. Never short-circuit Pin 6 to Pin 1
- Never short-circuit Pin 6 to Pin 1. Even with FETs open, a residual charge in the output capacitors can spark.
- Do not attempt to charge the battery through Pins 6 & 7 directly. The protection circuit expects SMBus handshake before enabling charging. Forcing voltage can blow the fuse or cause fire.
- Use thin, insulated probe tips – the pins are 1.25mm apart. One slip and you bridge VCC to SMBus (12V to 3.3V), destroying the embedded controller.
- If replacing cells, always preserve the original BMS board’s power to avoid permanent lock. Wire cells in parallel to keep BMS alive, or use a voltage injection method.
- Discharge the battery to below 30% before probing if possible – stored energy is lower.
Important Notes
- BMS Lockout: If you disconnect the internal cells from the BMS circuit, the MU06 battery will permanently lock (blow a chemical fuse or set a permanent failure flag). Do not attempt to "re-cell" this battery unless you have an unlocked BMS programmer.
- Voltages are with respect to B- (Pin 5).
- Do not apply external voltage to Pins 2, 3, or 4 – they are 3.3V logic pins.
- The actual wire colors may vary by OEM supplier (Simplo, Celxpert, or Dynapack). Always verify with a multimeter.
