EVOLTA is Panasonic’s most recent battery creation. It lasts longer than any of Panasonic’s Alkaline predecessors and in most cases Oxyride too. EVOLTA is being termed the next generation in the Panasonic spectrum of batteries. In designing EVOLTA, Panasonic focused on improving the StructureEvolution + Material Evolution + Manufacturing Process Evolution. By placing such an emphasis on enriching all three (Structure, Material and Process Evolution) Panasonic has been able to develop an extraordinary battery; one that has caught the attention of Guinness World Records™, which officially recognized EVOLTA as the "Longest Lasting AA Alkaline Battery in a wide range of devices." Guinness World Records™ made its determination of EVOLTA’s achievement based on third-party verified data obtained from discharge testing Panasonic conducted in accordance with the guidelines set by American National Standards Institute (ANSI) and the International Electrotechnical Commission (IEC).
