1. A method of battery monitoring comprising:

  • performing a first measurement on a battery cell installed in a location to determine a first charging capacity;

    determining a set of values for a permitted charging capacity trace region based on the first charging capacity and a number of charge/discharge cycles subsequent to performing the first measurement;

    performing a second measurement on a battery cell installed in the location to determine a second charging capacity;

    comparing the second charging capacity to the permitted charging capacity trace region; and

    determining that the battery cell installed in the location at a time of the second measurement is the same battery cell installed in the location at the time of the first measurement when the second charging capacity is a value within the set of values for a permitted charging capacity trace region and that the battery cell installed in the location at a time of the second measurement is not the same battery cell installed in the location at the time of the first measurement when the second charging capacity is not a value within the set of values for a permitted charging capacity trace region.
