Abstract
The present disclosure relates to a system for charging or maintaining a battery that includes power conversion circuitry configured to provide output power for charging or maintaining the battery. The system also includes electrical conductors coupled to the power conversion circuitry and configured to be coupled to the battery for charging or maintaining the battery. Additionally, the system includes control circuitry coupled to the power conversion circuitry and configured to monitor charging or maintaining of the battery. The control circuitry is further configured to determine whether the battery may be defective or failing based upon the output power and a time threshold.
