Until someone puts one of these BatMax battery life booster under a scanning electron microscope and tells me exactly what it is we're looking at, I'm going to presume that 'nanoceramic material' means 'tiny porcelain urns,' used by tiny, toga-clad Greek philosophers heft amphorae full of sloshing electrons. I'd say that's just as likely as a $13 sticker that "extends battery life from 30% up to 2x," "accelerates the charging time up to 40%," and "eliminates the 'memory' effect."
But I'm happy to be wrong. They could just as easily be tiny, toga-clad Romans.
