Li-Ion does tolerate extreme temps better, so apologies about that.
What I was thinking was that NiMH self-discharge slows down with cold temps...but, there's still the problem of warming it up to get it to pump the proper juice for light if it's left in the cold.
Li-Ion is probably overall better, all things considered, but it just isn't as affordable. I'll probably upgrade when I have nothing else to upgrade
