1. An apparatus for charging a battery, comprising:
- a mobile energy device adapted to store energy and deliver the energy to a load as a function of a modulated current charging signal without using a readily-available power source;
charge electronics adapted to generate the modulated current charging signal at or near a resonant frequency of the load as a function of a charging parameter, the modulated charging signal being delivered to the load.

Abstract
A battery charger with a self-contained power source which provides a current charging signal at or near the resonant frequency of the battery to be charged when no other power supply is readily available. A storage energy device, for example a battery, delivers a current charging signal modulated at or near the resonant frequency of a load, or stores energy from a source.

21. A method for charging a rechargeable battery, comprising:
-
measuring a resonant frequency of a plurality of batteries;
grouping some of the plurality of batteries with similar measured resonant frequencies into a resonant group;
averaging the resonant frequencies of the resonant group to obtain a group resonant frequency; and
charging one of the plurality of batteries in the resonant group with a signal modulated at the respective group resonant frequency.
