I read somewhere that keeping a NiMH battery in cold temps (even the freezer) can slow down the trickle drain effect of a not-in use battery. Is this true? If so, would I be better off leaving my NiMH battery on my bike overnight when it's 10degF outside? I know at least with standard alkalines that the cold wears the battery down, so I've always brought all my batteries inside, but this new piece of news could make getting rigged in the morning and eve WAY easier if it turns out to be true.

Caveat, the article also said if it was stored in the cold there needed to be an allowance for it to warm up before it would run at full speed. True?
