An apparatus 10 for measuring the state-of-charge of a battery 14. Apparatus 10 includes a shunt resistor 18, a pair of capacitors 64, 66, and a controller 20. Controller 20 selectively and alternatively measures the electrical charge of battery 14 with a first of capacitors 64, 66 while selectively discharging and calibrating the other capacitor 64, 66. In this manner, controller 20 continuously provides an accurate measurement of the "state-of-charge" of battery 14.
