| Pin Number | Signal Name | Typical Wire Color | Function | | :--- | :--- | :--- | :--- | | 1 | GND | Black | Ground (0V) | | 2 | GND | Black | Ground (0V) | | 3 | B+ (Battery Positive) | Red | Main power output (10.8V – 14.4V) | | 4 | SMBCLK | White or Yellow | Clock signal for SMBus | | 5 | SMBDAT | White or Yellow | Data signal for SMBus | | 6 | TH / Thermistor | Blue or Green | Temperature sense (10k NTC typical) |
If you cannot find a specific diagram, you can identify pins using a digital multimeter:
These are the smaller pins in the center. Typically, Clock (C) and Data (D) are located next to each other. You can often identify them by measuring resistance to the Ground pin; they usually pass through protection diodes. Lenovo Laptop Battery Pinout Diagram
