1. Apparatus for monitoring the condition of a battery comprising:
- means for monitoring the output terminal voltage of the battery and producing an output signal when the magnitude of the terminal voltage is less than a threshold value;
a stepping motor for integrating said output signal; and
indicator means driven by said stepping motor for indicating the integral stored in said stepping motor.

Abstract
The apparatus comprises means for sensing reductions in the output terminal voltage of the battery due to varying load conditions and producing a signal in response thereto during the time that the terminal voltage is below a threshold value. The apparatus further comprises integrator means such as an electronic counter or a stepping motor for integrating said signal and means for displaying the integral accumulated by said integrating means.
