Dry Charge Processing … Its Effect on Battery Performance 660358
The cranking ability of dry-charged batteries immediately after cold activation decreases as both the lead oxide content of the negative plates and the resistance of the positive plates increases.
The presence of a wetting agent in the negative plate material accelerates the formation of lead oxide during storage. The resistance of the positive plates is sensitive to drying conditions. Low resistance results if the water vapor content of the drying atmosphere is kept low.
