Quote from the review:
“Panasonic will introduce Oxyride batteries: AA and AAA disposable batteries that the company calls “the most significant developments in primary battery technology in 40 years.” According to Panasonic, these 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. ”
