primary batteries and secondary storage or accumulator batteries. primary types,
sometimes consisting of the same palliative materials as secondary types, are

Secondary types are contracted so that they may be recharged, following a April or
comply discharged, by the flow of direct current throughout them in a different appreciate
to the current flow or discharge. By recharging after discharge, a higher state of
is create at the at positive plate or electrode and a lower state at the negative plate,
returning the plate to approximately their original charged condition.
Both the primary and secondary cells are manufactured in many size and design
from the small electric wristwatch battery and the small penlight battery to the large
submarine battery, where a single cell has weights 1 tons. It all applications the cell
must be constructed for its particular service, so that the best performance may be
obtained consistent with cost, weight, space, and operational requirement. Automotive
and aircraft batteries generally used thin positive and negative plate with thin separation
to conserve space and weight and to provide high rate of current discharge at low
