Panasonic will introduce AA and AAA disposable batteries in June that the company calls the "most significant developments in primary battery technology in 40 years."
According to Panasonic, these Oxyride batteries last up to twice as long as premium alkaline batteries like Duracell Ultra ($5 for four), yet cost the same as regular alkalines ($4 for four).
Astounded yet? Then get this: Oxyride batteries are also supposed to deliver more power. The result, the company says, is that battery-operated toothbrushes spin faster, flashlights shine brighter, camera flashes are quicker to recharge and music players produce richer sound.
Play your cards right, in other words, and these batteries might just clean out your gutters, wash the car and do your taxes.

No wonder, then, that in Japan, the Oxyride batteries have captured 10 percent of the battery market in the one year they've been available. In fact, Panasonic predicts that Oxyride will eventually wipe out alkalines just the way alkalines blew regular "heavy-duty" batteries off the map.
