Note: In the trough battery, copper and zinc plates,
connected in pairs, divide the trough into cells, which
are filled with an acid or oxidizing liquid; the effect
is exhibited when wires connected with the two
end-plates are brought together. In Daniell's battery
, the metals are zinc and copper, the former in
dilute sulphuric acid, or a solution of sulphate of
zinc, the latter in a saturated solution of sulphate of
copper. A modification of this is the common gravity battery
, so called from the automatic action of the
two fluids, which are separated by their specific
gravities. In Grove's battery, platinum is the metal
used with zinc; two fluids are used, one of them in a
porous cell surrounded by the other. In Bunsen's or
the carbon battery, the carbon of gas coke is
substituted for the platinum of Grove's. In
Leclanch['e]'s battery, the elements are zinc in a
solution of ammonium chloride, and gas carbon
surrounded with manganese dioxide in a porous cell. A
secondary battery is a battery which usually has the
two plates of the same kind, generally of lead, in
dilute sulphuric acid, and which, when traversed by an
electric current, becomes charged, and is then capable
of giving a current of itself for a time, owing to
chemical changes produced by the charging current. A
storage battery is a kind of secondary battery used
for accumulating and storing the energy of electrical
charges or currents, usually by means of chemical work
done by them; an accumulator.
[1913 Webster]
5. A number of similar machines or devices in position; an
