or chips. If the battery cells are deeply discharged (below ~3.0V), the BMS may enter a "Permanent Failure" (PF) state, which requires specialized software like the NLBA PC Software or a TI EV2300/2400 to reset.
| Pin Number | Label / Name | Description | Function | | :--- | :--- | :--- | :--- | | | PACK+ | Positive Terminal | Main positive voltage output. Connects to the positive end of the cell array. | | 2 | PACK+ | Positive Terminal | Main positive voltage output (often bridged to Pin 1 for higher current handling). | | 3 | ID / TH | Thermistor / ID | Connects to an internal NTC thermistor. Used by the laptop to monitor battery temperature. Often serves a dual purpose as a security ID line. | | 4 | CLK | Clock (SCL) | I²C Serial Clock line. Used for SMBus communication between the battery BMS and the laptop EC (Embedded Controller). | | 5 | DATA | Data (SDA) | I²C Serial Data line. Transmits capacity, cycle count, and voltage data to the OS. | | 6 | SYS PRES | System Present | Often a logic signal indicating the battery is fully inserted. Usually pulled low or high depending on the circuit design. | | 7 | NC / ALM | No Connect / Alarm | Often unused (NC) or used for safety alerts. Can be a secondary temperature sensor in some revisions. | | 8 | PACK- | Negative Terminal | Main ground/negative output. Connects to the negative end of the cell array. | | 9 | PACK- | Negative Terminal | Main ground/negative output (bridged to Pin 8). | If you share with third parties, their policies apply
Working with laptop batteries carries inherent risks. Lithium-ion cells store dense chemical energy.
If the reading is even with Pin 5 grounded, the internal fuse is blown, or the BMS has locked out due to over-discharge protection. Technical Specifications of the HP MU06
