Standard mode charge at 110v most often because that's at work. At home 240v 32a. I don't charge at home unless I've been driving a lot. At 117v 15A standard charge finishes @ 185mi, but over the next couple hours it drifts up to 191mi usually. I don't see that upwards drift with 240v charging. I suspect that the slow 110v charge lets weak cells get more charge (because they're slow) and then the upward drift is from stronger cells giving up Ah to the slower cells.
