There may actually be value in going this way. Depends on if the %
life improvement exceeds the cost difference of course. One thing to
know about lithium....they pretty much provide full power and then
crash on you. Alkaline, on the other hand, tends to die gradually. It
is harder to know when you are losing power with lithium...however
performance holds together better during its life.

My devices have battery icons of some kind. I replace my NiMHs at
50%. If the device has 2 positions like my Sony Walkman I replace
when the icon shows half a battery. If it's 4 vertical bars like my
Zen Nano I change at 2. For my old camera and my Casio TV, I always
carry a freshly charged spare set.
