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.
