If you are worried about the min and max values: it is up to you to edit your sensors3.conf file to set them properly if the BIOS of your motherboard did not (apply the changes with "sensors -s").

This can be easily explained. In kernel 2.6.25, we fixed a bug where the w83627hf driver assumed that the BIOS had enabled VBat monitoring [1]. With previous kernels, the VBat value would be wrong if the BIOS did not actually enable VBat monitoring. Since kernel 2.6.25, the w83627hf driver doesn't assume anything from the BIOS as far as VBat is concerned, and enables monitoring if needed. When you reboot your machine, the W83627THF device is not reset, so the configuration steps done by the w83627hf driver of kernel 2.6.25+ remain. However, if you stop the machine then start it again, the configuration is lost.
