1. Apparatus for monitoring the output voltage of a battery used as an energy source for electrically powered equipment and for disabling a selected function of said equipment when the output voltage of said battery remains within preselected regions for a preselected time, comprising in combination:

  • a. first means for generating a first warning signal when the output voltage of said battery is below a first preselected value and for terminating said first warning signal when said battery voltage exceeds a second preselected value;

    b. second means for terminating said first warning signal and initiating a second warning signal whenever said first warning signal has persisted for a period exceeding a first preset time period;

    c. third means for terminating said second warning signal if the terminal voltage of said battery rises to a third preselected value within a second preselected time period; and

    d. disable means for diabling a function of said electrically powered equipment if the terminal voltage of said battery does not rise to said second preselected value within said second preselected time period.
