On the discharge, one cell of a lead storage battery gives an average
of about 2 volts, and a cell of alkaline storage battery about 1.2
volts, no matter what its size or the number of plates may be. When
there are more than two plates in one cell, all the positives in that
cell are connected together by metallic strips or bands, and all
negatives in the cell are connected together in a similar way.
Although we cannot obtain more than the above-named electromotive
force from one cell of either type of storage battery, we can obtain a
greater ampère capacity by using large plates instead of small ones, or
by using a larger number of small size.
The same effects are produced by connecting the cells in series, or
multiple, or multiple series, as we showed you in regard to primary
batteries; and the storage batteries may be charged as well as
discharged when connected in any one of these ways.
