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.
