Impact Although Urry’s development of the alkaline battery did not represent what one might call a striking technological breakthrough (since a wide variety of different types of batteries had been in use for several generations, and many would remain on the market alongside the alkaline battery), it certainly had a major impact on the commercial marketing of batteries used for everyday purposes. Because of their longer service life, and despite their visibly higher initial purchase price, alkaline batteries attracted buyers who wanted to avoid recurring unpredictability (and therefore a certain degree of risk, depending on the nature of the battery-powered device being used) associated with conventional zinc-carbon batteries. Success in market competition depends not only on the proven technical qualities of a given product but also on the attractive power of advertisements. Potential Energizer consumers came to recognize the company’s slogans during the mid- to late 1980’s: It’s supercharged! 1119 Inventors and Inventions Urry, Lewis Alkaline Batteries Understanding the basic principles of electrical current helps one to understand the workings of even the most commonplace flashlight battery. All batteries have a positive and a negative terminal. In large batteries such as those used in automobiles, the terminals are easily visible as lead posts, or poles; in most common batteries, the terminals are at opposite ends. In simple terms, electrical current within a battery occurs when electrons (which are by definition negatively charged) concentrated around the negative terminal flow via a conducting link (something as simple as a wire) toward the attractive force in the positive terminal.
