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. See http://www.piclist.com/#archives for details.
