As far as I know, the only advantage to LiIon over NiMH is the increased

NiMh if left a few months flatten and destroy themselves

Li-Ion is good for a year or more

That's no longer true, since about 10 years ago when Uniross came out
with Hybrio, and other manufacturers with similar products. Basically
they're just better made NiMH. They don't significantly self discharge,
in fact when you buy them they come already charged. Myself I have AA
NiMH which I've left on a shelf for 2 years and they still measure as
pretty much full.

Well thats news to me and welcome news at that.

Hated NiMh for that exact reason

Funny, I never noticed much drain on the original NiMH (probably lost about 25% in 3 months). NiCad, yes, they were appalling.
