ABSTRACT:
A storage battery sealed gas-tightly and liquid-tightly in which an electrode set with a pole lead is inserted in a battery casing fully open at one end and closed at the other end except for a central opening through which the pole lead extends. Insulation prevents electrical contact between pole lead and casing. A bottom disk is welded on the full opening of the casing to make it electrolyte-tight and gas-tight. Electrolyte is introduced through the central opening and the opening then sealed. In the preferred system, the pole is a hollow terminal post connected to a contact disk attached to electrodes of one polarity of the electrode winding. The electrodes of other polarity are connected to a bottom disk which is welded on the full opening.
