1. A system for differentiating and mitigating based on short circuiting in a battery comprises:
a detector coupled to the battery during discharge, wherein the detector measures voltage as a function of time and/or temperature;
a monitor in communication with the detector, the monitor including more than one predetermined profile of a battery shorting behavior, the profiles are based on empirically or mathematically modeled shorting behavior including temperature as a function of time and voltage as a function of time and are grouped as dangerous shorts and less dangerous shorts, and a comparator for matching data from the detector to the profiles;
a controller for sending instructions or taking action based upon information from the detector; and
an actuator for taking action based upon instructions from the controller.
