If you place a multimeter across Pin 1 (+) and Pin 7 (-), you might read 0V or a very low "ghost" voltage, even if the battery is brand new. To wake the battery up for bench testing, you generally need to bridge the System Present pin (Pin 5) directly to Ground (Pin 6 or 7) using a low-value resistor (typically 10k ohms) or a direct jumper wire. Connecting to Microcontrollers

Ensure you are using a genuine battery by scanning the QR code on the HP Security Label these pins using a multimeter? Solved: is mu06 compatiable with laptops with mo06 battery

All HP smart batteries, including the MU06, use the SMBus protocol. This means you can communicate with the battery's BMS using compatible hardware and software to read data like voltage, temperature, cycle count, and more. This is useful for diagnostics and advanced repair.

System Management Bus (SMBus) / Smart Battery Data (SBData) The HP MU06 Pinout Configuration

What are you experiencing with your MU06 battery?

Once slid into the laptop, the motherboard pulls Pin 5 to the ground rail (GND). This completes a detection circuit, signaling the internal microcontroller that it is safely locked inside the computer. Only then does the BMS fully energize the power blades. Bench Testing and DIY Considerations

Go to product viewer dialog for this item. is a standard 6-cell lithium-ion battery used in numerous Pavilion and Compaq series laptops. While pinout documentation is not officially published by HP, technical analysis of the battery's 9-pin connector reveals a configuration based on the protocol. MU06 Connector Pinout (9-Pin Layout)
