Abstract

A self-contained electronic device (4, 6, 8) instantaneously assess the stored energy capacity of single, two-volt; lead-acid cells (26); or of batteries comprised of such cells (26). The testing device is electrically connected to the terminals of a cell or battery (26) and measures its dynamic conductance with a small; time-varying signal (36). An internal conductance standard (24) permits initial calibration of the device to assure accuracy of the cell/battery measurements. Means (56; 58, 60, 62, 64, 66, 68) are provided for entering a "reference conductance", defined to be the dynamic conductance of an identically rated and constructed cell or battery having 100 % energy capacity. The device displays (50, 72) either the test cell/battery's measured conductance in Siemens (mhos), or its "percent capacity"
determined by appropriately scaling its measured conductance in accordance with "reference conductable". When determining "percent capacity", an LED (72) lights if the result is less than a preset threshold value (70).
