After som problems I mentioned in previous log, I made some minor tweaks. Charge termination worked perfectly again and in something like day and half worth of charging the capacitor was roughly at 2,65V, as seen on this graph of voltage versus time in minutes.

What to do with charged capacitor? Discharge it!
