You misunderstood David. David said to freeze his batteries to preserve them. When the battery gets cold it quit delivering power and quit the self discharge also thus preserve its power. At normal temperature batteries discharge themselves when not being used. Freeze them stop this. So if the FG is draining the battery, you can litterary freeze the whole thing the preserve the battery but then I don't want to freeze the camera as some components would crack.
