A battery monitor and cycle status indicator is disclosed. The battery monitor includes a voltage sensor capable of sensing the voltage between two nodes, for example, the positive and negative terminals of a battery. The voltage sensor is connected to an analog-to-digital converter which converts the analog voltage level sensed by the voltage sensor to a digital form. In turn, the analog-to-digital converter is coupled to a microprocessor. The microprocessor determines battery state-of-charge and historical values that relate to battery condition based upon the voltage levels provided by the analog-to-digital converter. The microprocessor is also coupled to a memory which stores battery history values computed by the microprocessor and program instructions for operation of the microprocessor. The battery monitor also includes a display that is capable of displaying battery state-of-charge and the historical values determined by the microprocessor. A switch is coupled to the microprocessor to inform the microprocessor to clear the history values presently stored in memory or to scroll the display from one battery parameter or history value to the next. The switch also enables the adjustment of the battery parameters that are stored in the memory to user-defined levels.
