✦ Synopsis

The electrical conductance of negative lead-acid battery plates was measured in situ by the d.c. method. By subtracting the conductance of the grid, the conductance of the active mass was obtained. With freshly charged plates this was appreciably lower and increased with time; this effect was attributed to adsorption of hydrogen on lead. During cycling, a decrease in the conductance was observed which is discussed in terms of recrystallization of the active mass. The conductance of dry plates was found to be appreciably lower than that of wet plates.
