So I was just watching the movie Apollo 13, which I love, and I heard something that didn't make a lot of sense to me.
During one of the scenes where they are about to re-enter Earth's atmosphere, Fred is checking the battery gauges...I don't remember the exact verbiage of the scene but he while checking one of the batteries he says "No volts, 2 amps".
Is this a possible characteristic of a battery or is the movie just stretching the realm of possibilities a little? My thought is that a battery can not possess any amps without voltage but I wanted to have this re-affirmed by you knowledgeable people.
