Thanks Jim. Ohm’s law – copy that! 🙂

The coulomb counter I’m using is from Sparkfun. It pulses one of its pins low each time that 0.614 coulombs of charge have passed through its sense resistor. Very easy to use.

Regarding the decreasing current: Is it possible that the battery’s internal resistance is increasing as it discharges, and this causes current flow to decrease? I’m no EE, so I’m just making a guess.
