There hasn't been a 'memory' problem in nicads for decades. It is an old
tale that is untrue. Over charging NiCAD can cause volatge sag issues but if
you have a decent charge that is not a problem. LiION, NiMH on the other
hand have a much higher energy density per unit of weight than NiCad but
they self discharge very quickly. They also have a finite life of only a few
hundred charge/discharge cycles. For radios that sit in your flight bag you
are much better to use NiCad's. But even those are discouraged for use
because of disposal issues. Cadmium is very bad for the environment. That
means the best overall solution is probably NiMH.

Exactly wrong.
Huh? Describing your own post?
NiCads don't have a memory problem
Of course they do. Continually charge them before they are fully
discharged
and you will find they no longer take a full charge. There's a dramatic
difference in lifetime between a NiCd battery that is always fully
discharged and one that's not, with the always-discharged one coming out
way
ahead.
and alkalines self discharge like crazy.
If by "self discharge like crazy" you mean "hold a charge for years", then
you're right. Otherwise, you're on crack.
I'd be happy to supply the research data proof
on the NiCads
I've got all the research data proof I need, having both killed NiCd
batteries early, and babied NiCd batteries to decade long lifetimes.
and if you want to lose the self discharge problems go
with a lithium battery pack.
Li-ion batteries self-discharge way faster than alkalines. To make
matters
worse, if you allow them to be stored at full charge, they wind up with a
"memory effect" very similar to that found with NiCd batteries (albeit for
a
different reason).
