anyone tested these side-by-side for runtime?
given the physical constraints of li-ion cells, in Wh/cc, i find it hard to beleive that they can cram 33% more power intot eh same space. i got a power hungry piece of gear that gets 2 hours out of a 3350, was considering a 3450 or a 3450+add-on cell. i imagine with the add-on cell, you get a little more than the runtime of two individual batteries used successively as the current drain is cut in half.
