ABSTRACT:
The charger mounts a printed circuit board into a case and charging contact points are fixed on this printed circuit board. The charging contact points are connected to the electrodes of the batteries attached to the attachment section. The separating ribs in which the charging contact points mount and which are in contact with the upper face of the printed circuit board, are provided in the case. The charging contact points mounted in the inner side of these separating ribs, are exposed in the attachment section from the electrode windows of the case. The fluid which penetrated inside the case via the electrode windows is separated by the separating ribs and prevented from spreading at the surface of the printed circuit board and is drained outside the case through the drain canals provided in the case.
