After exstensive testing of batteries with my Zoomer and HP200LX
I can say without doubt that Lithiums are NOT more economical to run. The
cost of standard alkeline batteries being what they are, especially when
bought in bulk packs of 8 or 16, you can't compare the two. The only real
advantage of lithiums, that I can see, hasn't been mentioned. They weigh
less... (slightly, but still a consideration when talking about portable
units.)
