You are correct drmiller. Your post reminded me , so I just went and checked it. The voltage varied from 14.2V to 14.4V, but it mostly stayed in the 14.3-14.4 range. So, we'll say 14.35V as an average.
14.35V gives us 3.575V per cell. That is going to leave these cells pretty much topped off all the time. Max charge voltage is 3.65V per cell and you gain very little capacity between 3.575V and 3.65V according to the charts.
I actually wouldn't mind a slightly lower voltage, but this is what I have. I don't believe there is an easy way to adjust the alternator output. Someone correct me if I'm wrong. But, this should do just fine.
