I think you could let the battery sit for a while, check the resting voltage, from that guess at it's state of charge. Run it at a pretty low current (so the Peukert effect doesn't come in to play?) for a specific amount of time, let it rest for a few hours, check the state of charge and figure it out from that. That sounds really annoying.

I tried it with the wax paper. It needs fine tuning. I pressed to hard, and it smooshed the ink all over the place!
