Abstract
The present disclosure provides a battery charger to which a battery pack may be coupled. The battery charger includes a housing, a terminal block, and a receptacle. The housing includes a battery receiving interface that defines a recess that extends inwardly toward a cavity defined in the housing. The terminal block is disposed in the recess. The receptacle is coupled to the battery receiving interface and a seal is interposed between the receptacle and the battery receiving interface. The battery receiving interface, the receptacle, and the seal cooperate to form a chamber between the terminal block and the cavity.
