Battery temperature, as provided by IOKit.
This tool was originally developed to determine the temperature of my laptop while working outside on a hot day.
It has been adapted to compile for any platform with IOKit (e.g. macOS, iOS).
Exit status codes have been added to make using iobat with scripts easier.
Usage: iobat [-s]

0 if the temperature is within recommended operating temperatures,
1 if the temperature is too low,
2 if the temperature is too high,
3 if the temperature is either too high or low, but which cannot be determined.
