  • Lead accumulator
    Patent number: 4138533
    Abstract: A lead accumulator is of the tall constructional kind for use in, for example, stacking or fork-lift trucks, submarines or power stations. To achieve satisfactory current and voltage characteristics for high electrode plates and for production purposes, the plates are formed with current lugs along their side edges. The current lugs of plates of the same polarity are electrically and mechanically connected together by a pole plate of high electrical conductivity extending along the side edges of the electrode plates.
