Canon EF Long Exposures

I used to do a lot of night photography with my A1 and found that a couple of time exposures of a minuet or more the battery was flat, which was why I bought an FTb that has a mechanical shutter. I don't know if modern electronic shutters are still like this, but the EF is a very fine camera, built like a brick s**t house I'm sure it will give you some great reults.
