I have no idea where you have gone with this.  I explained that I had 2 Optima
starter batteries fail, and that I had no opinion about the other 2 types of
Optima batteries.  As an electrical engineer and general purpose geek, you can
be assured that I know what I'm talking about.

What happens if a big asteroid hits the Earth?  Judging from realistic
simulations
involving a sledge hammer and a common laboratory frog, we can assume it will
be pretty bad.
