1. A method of charging a battery, comprising:
- determining a resonant frequency of the battery;
simultaneously feeding through the battery a constant direct current and a series of current pulses at a frequency that corresponds to the resonant frequency, wherein each pulse in the series of the current pulses comprises constructive resonant ringing that is constructive with the respect to charging the battery; and
artificially enhancing the constructive resonant ringing of each pulse before feeding the pulse through the battery.

Abstract
The inventive subject matter provides a circuit and a method for efficiently charging a battery. In one aspect of the invention, the circuit includes a constant current circuit configured to provide a direct current through the battery. The circuit also includes a pulsing current circuit that works with the constant current circuit and configured to simultaneously provide a series of pulsed current to the battery. In some embodiments, the series of current pulses includes constructive resonant ringing that is constructive with respect to the charging of the battery.
