A battery charger (10) comprising a housing (15) enclosing battery charging electronics (11), an interface (12) connectable to a mains outlet, and a charging current output interface. An aperture (71) is formed in a wall (75) of the housing, and a pressure relief valve (90) is arranged in said aperture, functioning to open and evacuate gas from the interior of the housing to the exterior of the housing when the pressure in the housing exceeds a pressure limit relative the exterior of the housing. In one embodiment, a bushing (90) for a cable (80) interconnecting the battery charging electronics (11) and the charging current output interface acts as the valve. |
