Alkalines have a problem when you get to the power levels we are talking about
for transmit. They last a mercifully short time in most HTs. We've found that
popping for the NiMH cells is far better from a time and life point of view.

For an emergency only radio, NiMH are about the worst battery to use. They have a
self discharge rate of 10% per day. The Lithium Ions are the next best then
NiCd. Of course the self discharge rate of alkaline batteries are a lot better
than any of the rechargeable but they don't do well with high current loads that
some electronic equipment need. The non rechargeable Lithium batteries are the
best in that regard, they last a long time, lowest self discharge rate of any
battery and they can take the high current loads, the only down side is they are
expensive, especially if you go to the corner drug store where they some times will
charge $8 or more each, if you look around on the internet you can get them for
less than $2 each. Of course that doesn't do much good if your radio doesn't have
a pack that will take the CR123 lithium batteries.
