Most historians date the start of battery development from the late eighteenth century. However some archaeological finds may push the date back as far as 2,000 years ago. In 1938 Wilhelm Konig made a discovery in Iraq of a 5 inch pottery jar containing a copper cylinder that encased an iron rod. Koniq decided that this was an ancient battery.
The history of batteries and development of devices go hand in hand. When Eveready invented the first miniature batteries in the late 1950’s, most of the world stopped winding watches. Alkaline batteries provided enough power to make way for portable radios, boom boxes and toys that beep and blink. With the introduction of lithium batteries , it opened up a while new world of long-lasting power for high-tech devices from digital cameras to MP3 players and handheld computers.
