Hydration
Dry cells are not "dry ". The water in the electrolyte is the medium which transports the ions The loss of water will render the cell useless. Mike has pointed out that failed cell are dried out at the electrodes. Venting dries out cells.
During use the water tends to be driven away from the higher resistance areas by the heat generated and it tends to accumulate in the cooler areas. Over years of non use (rest) the water distribution in the electrolyte (what remains of it) will tend to be equalized again.
Whether this is so could be determined by doing an ionization/conductivity test on a micro level throughout the electrolyte of deteriorated cells as compared to recovered cells. A direct measurement of the water content of the electrolyte at the micro level would be a more direct method. Either method is difficult to do.
