Why aren't AA batteries square?

Is it cheaper to make batteries cylindrical or something? If they were square in crosssection, they wouldn't roll off the desk. -- I think the real reason was because AA was meant to replace SP7/HP7s so if they'd made the AA square they wouldn't be able to be used in the products that took SP7/HP7s |
