   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.

   5. A number of similar machines or devices in position; an
      apparatus consisting of a set of similar parts; as, a
      battery of boilers, of retorts, condensers, etc.

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

   7. The box in which the stamps for crushing ore play up and
      down.

   8. (Baseball) The pitcher and catcher together.
