Certainly if they're actually in use, batteries will drain more quickly 
when they're cold. A good example is my digital camera, whose battery 
normally easily lasts long enough to take the ~50 pictures that fit onto 
the memory card. But when I was taking pictures outside at a temperature of 
around 0 degrees (for the Americans: Celsius) last December, I think I only 
got to about 25 pictures or so before the "battery low" icon appeared on 
the display. (It also started acting up in other ways, so the lesson I 
learned is that electronic equipment doesn't necessarily work very well at 
low temperatures -- something to keep in mind for an ME assignment taking 
place in cold weather.)
