1. A method for determining the condition/classification of automotive and other batteries in accordance with one or more sensed parameters thereof comprising the steps of:

  • a) applying a transient electrical test parameter to the terminals of a battery to be tested for no more than one second;

    b) utilising a characteristic of the battery'"'"'s reaction to said test parameter as a basis for said determination;

    c) said method further comprising the step of utilising the battery'"'"'s reaction to said transient test parameter to provide a measure of the condition of said battery by analysis of the waveform shape or profile of an electrical value representative of the battery'"'"'s reaction to said test parameter;

    characterised byd) the step of analysis of the waveform profile of said electrical value of the battery'"'"'s reaction to said test parameter being effected without employing a neural network but by means of an algorithm adapted to identify a corresponding one of two or more battery condition classifications, and said corresponding one classification exhibiting a correlation with time-defined voltage aspects of said waveform profile of said electrical value.
