Patent number: 7635537Abstract: Lead-acid storage batteries of the type having a plurality of cells, each including alternating positive and negative plates, each plate including an upstanding lug, and a partition separating adjacent cells are provided with unique improved lighter weight and lower resistance plate and intercell connectors. The connector comprises at least one cell plate connector including a wall with a multiple spaced slots for receiving the lugs from either the positive or negative plates of the cells. A strap extends from the cell plate connector. The cell plate connector and the strap are formed of a metal substrate that has a lower specific gravity and higher conductivity than lead, the substrate having a lead-based outer coating that resists the corrosive effects of the battery acid. A small amount of lead is then applied covering the slotted wall and at least a portion of each lug to insure good connection.Type: GrantFiled: July 5, 2005Date of Patent: December 22, 2009Assignee: Concorde Battery CorporationInventors: David G. Vutetakis, John B. Timmons, Ramesh C. Bhardwaj
