ABSTRACT:
A storage battery has an axially extending housing divided into axially extending blocks each containing a plurality of individual cells. The housing has a pair of plus-minus contact terminals equal to the number of blocks with the terminals accessible from the exterior of the housing. Voltage is supplied to each pair of terminals corresponding to the sum of the voltage of the cells within one block. The charging operation in the individual blocks is performed consecutively in an appropriately shaped charging device having a charging voltage corresponding to the voltage of one block. The voltage of the individual blocks can be utilized in series or in parallel connection by an appropriate electronic arrangement within an electrically driven tool.
