    In a previous post,cobitech suggested a method for charging units.This seems to be a great tip. I appreciate reading and learning things like that very much,as I am sure a lot of people are that use this forum. What I want to make sure of is by low temp does that refer to a freezer,medium temp a fridge or reach-in cooler or the like,and high temp maybe a flower case or similar?My thanks to whoever would like to clarify this for me.I want to be sure of what I pick up in this forum.Thanks again.
