Abstract
A battery charger detection system is provided. The battery charger detection system includes a battery charger, an indicator, and a controller. The controller detects an initial electrical coupling of the battery charger to a battery and measures a first voltage of the battery upon the electrical coupling. The controller further measures a second voltage of the battery and actuates the indicator in response to both a continued electrical coupling between the battery charger and the battery and the second voltage being less than or equal to the first voltage after a predetermined length of time.
