Djoobahjieh (and btw what sort of incantation is that?),

The comparison is based on energy density. Ballpark would be 170-180 wh/kg for Valence's new cells, versus 'average' li-ion cells providing 115-120 wh/kg (yeah, yeah, some are a *bit* better, many are a *lot* worse, e.g., 100 wh/kg).

Your comparison depends upon the size of the battery as well as the energy density. I have friends whose laptops get 4-6 hours depending upon how hard they're being worked; but those laptops have bricks for batteries. Valence could provide at least that sort of performance with a slim laptop with a 'sheet' of 4mm thick cells behind the screen. Bulk it up and you can get more performance.

Lev did state that their tests which resulted in 8-10 hours involved heavy power consumption (eg, playing DVD disks, etc).

Bottom line: the cells *will* outperform all others. *When* they are finally in the market, then PC mag et al can do their comparative evals and then we'll know more precisely how they line up.
