Antique Full Thomas A Edison Collectible 4" Battery Oil Bottle for Railroad Use. Still full and never used. Nice item for the Railroad or Bottle Collector.1) Thomas A. Edison Primary Batteries were widely used on railroads to energize track and signal circuits. The battery consisted of a glass jar 6" in diameter and 10" high. Each cell produced 0.8 volt. The elements had to be renewed at various times due to train density and other factors. The new elements consisted of zinc and lead plates, a can of caustic soda, and a small glass of oil. The caustic soda was mixed with water, the elements were suspended in the solution, and the battery oil was added to the top of the solution to prevent evaporation.2) Battery oil is a pure nonconductive oil that is added to the potassium-based electrolyte in old Edison nickel-iron batteries to reduce water loss due to excessive gassing. These batteries were used with wind generator electric systems because they can be cycled at high rates without damage. Due to their high-charging characteristics, the Edison battery will boil the water out very quickly without a film of oil on the electrolytic fluid.The glass is in perfect condition with no chips, cracks etc. The cap does have some wear to the finish/paint.
