to the posi-tive pole of the battery. The voltage of charging commences at about 2 volts per cell, and rises to2.6 volts at the full charge while taking current at the normal rate shownon the makers lists. The curves in Fig. 3 show the voltage of a cell during charge and dischargeat the normal… … This cut shows the general forms of the charge and discharge curves atany rate; but in commercial use cells are almost always worked at muchhigher rate than shown in the cut, and give lower efficiencies. For exam-ple, a five-hour rate of discharge is quite usual, and in some cases evenhigher rates.…
