I think I put something like 14kWh into my set of 40 when I got them. Remember that you are only putting 0.13A average into each 100Ah cell. That is a very slow charge. Mine didn't take 6 days, however. Probably because I was using a 10A charger.
What is the terminal voltage right now? There is very little energy above 3.4V. I did a test where I recorded current and voltage by hand of a 100Ah cell starting at 3.40V and ending at 4.00V and got at most 0.65Ah into it. Because of the way I calculated Ah this number would error on the high side.
