[Elecraft] Experience with Energizer Lithium AA Batteries?

[Matthew Cook]

Walter,

These cells have a slightly higher terminal voltage 1.82 c.f 1.65 (when
full) from your normal heavy duty alkaline battery... flat is still the
same at 1.0V under load discharge curve is what you'd expect under
moderate/high loads.

We regularly fly these (and only these cells) in our high altitude balloon
experiments at reasonable currents (> 200mA), so at temperatures below zero
celsius (+32F) they still have significant *usable* capacity.   They will
certainly give your Enerloops a run for their money.
