The company was founded in 1970 by Mr. Wilson Greatbatch, an electrical engineer and the co-inventor of the cardiac pacemaker, Mr. Greatbatch believed in 1970 that the remaining problem to be solved for the pacemaker was the battery. He licensed the lithium/iodine technology, hired experienced battery scientists, and marketed the lithium/iodine battery to the pacemaker industry. By 1977, virtually all pacemakers were powered by lithium batteries. The company has grown through acquisition and market growth. Sales in 2010 were > $550 million. There are ~3000 employees at present. There are facilities in Western New York, Mexico, Minneapolis, Pennsylvania, Indiana, Switzerland, and China. Greatbatch, Incorporated

What is a battery (electrochemical cell)? “Battery” means a device consisting of one or more electrically connected electrochemical cells which is designed to receive, store, and deliver electric energy. An electrochemical cell is a self-contained system consisting of an anode, cathode, and an electrolyte, plus such connections (electrical and mechanical) as may be needed to allow the cell to deliver or receive electrical energy . - Federal Government Definition

The Baghdad Battery     A 2,200-year-old clay  jar found near  Baghdad, Iraq in  1936, has been  described as the  oldest known electric  battery in existence.  The clay jar and  others like it have  been attributed to the  Parthian Empire — an  ancient Asian culture  that ruled most of the  Middle East from 247  B.C. to A.D. 228. It is  thought that the  “battery” was used to  electroplate jewelry  The nondescript earthen  jar is only 5½ inches high  by 3 inches across. The  opening was sealed with  an asphalt plug, which  held in place a copper  sheet, rolled into a  tube. This tube was  capped at the bottom with  a copper disc held in  place by more asphalt. A  narrow iron rod was stuck  through the upper asphalt  plug and hung down into  the center of the copper  tube — not touching any  part of it.

The Voltaic pile In 1799, Alessandro Volta (1745 – 1827) arranged a vertical pile of metal discs (zinc with copper or silver) and separated them from each other with paperboard discs that had been soaked in saline solution. This stack became known as the voltaic pile and was the progenitor for modern batteries . The French word for battery is “la pile.”
