1. Battery monitoring apparatus for observing the charge condition of a plurality of battery cell groups, each cell group comprising at least one cell, comprising:

  • a display panel having a multiplicity of visual display means for providing a separate quantitative indication of the charge condition of each one of the plurality of cell groups being monitored and of the plurality of cell groups collectively;

    means for driving the visual display means in response to a measured voltage potential related to the condition of each cell group to cause the visual display means to exhibit separate quantitative visual displays corresponding to the measured voltage potential of each cell group; and

    means for coupling the driving means to plural cell groups;

    whereby the quantitative charge condition of a single cell group and of a plurality of cell groups may be individually determined by observation of said display panel to provide for diagnosis of cell group conditions for purposes of monitoring and replacement.
