1. A faulted circuit indicator comprising:
an internal power source;
a sensor system configured to measure a voltage at the internal power source and to measure a temperature at the internal power source;
a controller coupled to the sensor system, wherein the controller is configured to determine a health status of the internal power source based on the measured voltage at the internal power source and the measured temperature at the internal power source; and
an indicator module coupled to the controller, wherein the indicator module is configured to provide an indication of the health status of the internal power source, and the health status of the internal power source is related to an amount of remaining life of the internal power source.
