It was noticed on the high rate discharge, when discharged down to about 80 amperes that the voltages of the P&R cells were lower, the Gould being 1.28 & (approx:) respectively. So these have not yet reached their point of life where they will give a capacity equal to that of the Gould. Signed G.J. This Sheet must be filed on completion of the work. | ||
