panasonic launched their new AA Evolta product in Japan in April 2008 and in the United
States in May 2008. The name Evolta is derived from the words “evolution” and “voltage,” and this
cell has laid claim to being the first of its kind to have the Guinness Book of World Records officially
certify it as the “world’s longest-lasting AA alkaline battery cell” along with having a reported shelf
life of 10 years. It derives its increased performance from the addition of a titanium oxyhydroxide to
the cathode, a thinner can, thinner seal, and increased collector length. The discharge performance

of this cell can be seen by visiting panasonic’s website. 17
