Abstract

A system for monitoring the starter battery of a vehicle includes a central processing unit, a voltage sensor, a temperature sensor, a timer, a data store, and a display. A collection of computer software algorithms are executed by the central processing unit to ascertain the operational state of a vehicle's starter battery. The algorithms are operative to determine engine start time, initial start voltage drop, and the charge state of the battery.
