| 2 of the same type of batteries in a home exercise ski-machine to
| power a monitor that shows time elapsed, calories, distance, and miles
| per hour for 180 minutes a week are still in use after three months!!
| 2,800 minutes?!!?

The batteries are most likely not used to power the screen once you get
going. They're just there to provide micropower when the machine isn't in
use.
