I’m sure when Panasonic claimed that its EVOLTA AA batteries where the longest lasting on the market, you rolled your eyes. Right? ‘Cause how many times have you heard that pitch. Now Panasonic has a fancy certificate from the Guinness World Record folks to shove in the face of all the haters proving that its AA battery is alkaline battery cell in the world.

To further support its AA battery claims, Panasonic also conducted device testing and results of those tests include:

A digital camera powered by EVOLTA batteries took 272 shots compared with 209 shots when powered by Panasonic’s current Alkaline Plus batteries — an increase of 30%.

An FM radio played up to 14 hours longer when powered by two EVOLTA AA batteries than when powered by Panasonic’s current Alkaline Plus batteries.

A remote-controlled car traveled as much as 8.7 miles farther when equipped with six EVOLTA AA’s than when powered by Panasonic’s current Alkaline Plus batteries.

The batteries are currently for sale with four-packs going for $4.99 and eight-packs for $8.99.
