As an electrician, who lived and worked in NY for many years, I think I know a battery has a charge, and unless the alternator is running, anything turned on, powered by that battery will drain it.
The cranking amps required to turn the starter is the same whether the lights (or any other power-using device) has been turned on or not.
Many times, going out to my car on 17 degree mornings, brushing the snow off the door to open it, the LAST thing I would do is turn on anything, if I thought the battery was weak.
Maybe YOU could explain scientifically, what you mean by "waking up" the battery. If you THINK if works for you, great, I'm glad for you.
