1. A method for assessing health of a power source, the method comprising:
- measuring voltage and current of a power source in a system using a device in the system as the load;
determining an internal resistance of the power source based on the measured voltage and current; and
determining and providing a health assessment of the power source based at least on the determined internal resistance and a stored baseline internal resistance for the power source.

Abstract
A method and system for assessing health of a power source includes measuring voltage and current of a power source in a system using a device in the system as the load. An internal resistance of the power source is determined based on the measured voltage and current. A health assessment of the power source is determined and provided based at least on the determined internal resistance and a stored baseline internal resistance for the power source.
