Another aside: Battery terminals are labeled "+" for Positive and "-" for Negative. But, that's misleading. If the "+" terminal is Positive relative to the other terminal, then how is that other terminal Negative"? Negative relative to what? It should be called the "Zero" terminal. Or "Reference" terminal. Or, even, the "Ground" terminal. But then, that flies in the face of an arbitrary reference point.

So, the names of the terminals should actually be:

  • Positive in relation to the other terminal
  • Negative in relation to the other terminal

Or for short:

  • Positive terminal
  • Negative terminal

And for even shorter:

  • +
  • -
