Panasonic unveils Evolta super battery and companion robot

The fight to keep your robot running longer and your electronic doodads powered has a new champion: the Panasonic Evolta battery. The double-A battery is said to have a lifespan 20% longer than its competitors, including Duracell and Energizer, and a shelf life up to 60% longer. The battery even has a cute little robot mascot to encourage you to buy the premium priced batteries ($5.40 for four) scheduled to go on sale in Japan in April with a worldwide rollout later this year.
