A system for monitoring and reporting on the condition of a battery installed in
€ƒ€ƒ€ƒ a vehicle having an engine and an ignition. The system comprises a sensor for determining the voltage across the battery terminals under conditions of current drain of the vehicle electrical system to determine the quiescent voltage current drain value (QV). Mean calculates the battery state-of-charge (SoC) on the basis of the determined QV.
