   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
      apparatus consisting of a set of similar parts; as, a

   6. (Metallurgy) A series of stamps operated by one motive
      power, for crushing ores containing the precious metals.
