<P>PROBLEM TO BE SOLVED: To provide a battery that does not discharge alternating current using a copper plate instead of a lead plate. <P>SOLUTION: A battery that does not discharge alternating current using a copper plate instead of a lead plate includes diluted sulfuric acid therein which makes a copper plate shiny and generates electricity by increasing its temperature. The battery is a direct vent type and requires no maintenance. Depending on the number, length, and size of the copper plate connected for each tub, it may be used for small capacity and large capacity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
