1. A system for charging a battery having at least first and second electrodes, comprising:
- a power source for applying electrical energy to the electrodes of the battery; and
a source of sound waves for subjecting the battery to acoustic excitation substantially simultaneously with the application of said electrical energy, wherein said source of sound waves is selected from the group consisting of;
an ultrasonic bath adapted to contain the battery during charging;
at least one air jet directed to impinge on the battery; and
a fluid container fabricated from a flexible material and enclosing a sound transducer, said fluid container being acoustically coupled to the battery.

Abstract
The present invention is a system and method for enhancing the charging of a battery by exposing the battery to acoustic excitation while the battery is being charged. By adding acoustic excitation to the charging process, the present invention reduces the time needed to charge the battery, reduces the energy needed for charging, and increases the battery'"'"'s cycle life. The present invention may be used to charge new and used batteries and to rejuvenate dead batteries.
