Power for DSLRs in the field

Do those of you who use DSLRs for imaging reply on the standard batteries for power? Or do you use the optional power cord with a 'power tank' or similar?

I know that many exposures are fairly short, but even a couple of minutes must drain the battery fairly quickly. I remember taking 30-second exposures of Comet McNaught used up my three batteries quicker than I expected (using a Canon 10D).

I noticed that some of the wide-field exposures in the images forum involved 16-minute exposures with a 5D. Would the battery last that long?
