Hi Wendell,

from http://www.odysseybatteries.com/specs.htm the weights are:

680     - 14.5 lbs
680MJ - 15.4 lbs
625    - 13.2 lbs

So it appears the 625 is at least a pound lighter.  I will say that the
680 is a nice red color but the 625 is an ugly black.

Bernie,
Now that is the kind of information I've been looking for. What starter are you using in this test?
  No one agreed on disagreed with my assumption that the PC625 battery would be the one to choose if it weights less than the PC680. According to the charts the PC625 has 3 minutes more reserve than the PC680 but a little less in the cranking amps.  Your measurements reinforce my belief. Am I wrong?? Anyone have the weights of these batteries?
Wendell
