Quality targets for lead battery production have always been determined by falling within certain parameters.
In the specific case of curing and drying of battery plates, certain free lead and residual humidity parameters must be achieved.
One cannot always take for granted to be within these parameters because there are many variables to contend with, such as:
The type of chamber,
The exhaust system of the factory
The vectors used for generating heat and moisture
The internal flow of the chamber itself
