Panasonic plans to bring to the market a battery that it says is the most significant advancement in the technology behind batteries since alkaline was introduced in 1965. Called Oxyride, the company claims that the batteries will last up to twice as long as traditional alkalines.

The battery has already had a successful launch in Japan, and Panasonic plans to have it available in all major markets shortly. Initially, the batteries will be made in the AA and AAA sizes.

Behind the technology are newly developed materials inside the battery, along with an improved manufacturing process. These materials allow the battery to maintain voltage at a higher and more stable level, which is ideal to power modern electronics.

The battery also averaged a lifespan of 1.5 times that of alkaline.

"Oxyride is the first real change in consumer batteries since the alkaline," adds Kimberlin. "Imagine the incredible changes in portable products over the past 40 years -- now the batteries have finally caught up."

Both batteries will sell for a manufacturer's suggested retail price of $3.99 USD for a 4-pack.
