from what i gather, the chip will compare the input voltage from the battery to the internal voltage and detect the difference? am i close?
This link will explain voltage dividers.

The divided voltage will the go to an ADC pin of the PIC. The voltage will then either be compared to the voltage that the PIC is running on or a reference from another source(voltage divider).
