2 | KEY | |
3 | CLK | |
4 | DATA | |
5 | THERMAL | |
6 | GND |
This is the main and backup (UltraBay) battery pinout.
THERMAL is a 10Kohm NTC resistor with the other pin connected to GND.
The i2c/smbus CLK and DATA lines of the battery have no internal pull-up resistors, therefor relying on the host systems pull-ups.
