The latest battery innovation from Panasonic will feature in the Guinness Book of World Records 2009 as the world’s longest-lasting AA alkaline battery.

This is the first time a battery has been endorsed by an independent body, the company claimed. The new Evoia sub-brand, launched at the end of next month, will be available in four sizes: AA, AAA, C and D.

It has been designed to perform equally well in applications with low, medium and high energy demands, another market first, said brand marketing manager Tim Clark.
