I think it has more to do with perhaps how much torque the clamp, holding it fixed in its position, should have before the case is stressed and fractures under it as a result.

I was just looking at a UPS system that impressed me during the last power outage we had. The interesting thing was the batteries, they are 2.5V batteries bigger than car batteries! I wanted to see what AH rating they were but all I could find was a Torque rating. The rating was 70 inch pounds, what the heck is a Torque doing on a battery?? How would I convert this to an AH rating? Thanks, TTYL -- http://www.piclist.com hint: The PICList is archived three different ways.
