If I had the batteries and some spare time, I'm sure I could run some very accurate discharge tests on any of these batteries. One of my more recent programs here at work had 2 - 6kW programmable load boxes (

It could also be programmed such that you can cycle through current spikes at various intervals. Add a data recorder to that and it would be real easy to plot the current versus voltage in a very controlled situation. I may have to look a little further into where all the equipment is now to see if it's something that would be feasible to come in and do on a weekend. Is this something you guys would be interested in seeing if I could do it?
