Abstract: A battery charger usable with rechargeable battery. The battery charger includes a housing and a handle. The housing includes a connection rail. The connection rail slidably interfaces with the rechargeable battery. The connection rail extends parallel to a plane. The handle is movably coupled to the housing. The handle can be positioned in at least a first position and a and a second position. In the first position, at least a portion of the handle intersects with the plane. In the second position, the plane is not obstructed by the handle.

Abstract: A charger includes a housing with an interface positioned in a front wall and configured to engage a battery pack. The interface includes charging terminals positioned between a first rail and a second rail, a first groove positioned between the first rail and a wall of the housing, and a second groove positioned between the second rail and the wall of the housing. The interface is in communication with an interior of the housing. A fan is coupled within the housing adjacent the interface, and an air passage member includes a hollow body that has a first end coupled to the fan and a second end spaced apart from the first end extending through another wall of the housing. The fan is operable to suck an air flow into the housing from outside the housing and guide the air flow through the air passage member to the interface.

Abstract: A battery charger includes a housing defining a first end, second end, front side, rear side, top side, and bottom side. The housing also defines a first support structure to selectively couple to a battery pack and a second support structure to selectively couple to the battery pack. The housing further defines a first air inlet located in the front side and a second air inlet located in the rear side. The housing also defines a first air outlet located in the first end and a second air outlet located in the second end. Charger electronics are supported in the housing and operable to output a charging current to charge the battery pack. A fan is operable to generate an airflow through the housing. The airflow extends from the first air inlet and the second air inlet to the first air outlet and the second air outlet.

Abstract: The present disclosure provides a battery charger including a housing, a battery-cooling fan, a duct, charging electronics, and an electronics-cooling fan. The housing includes a battery interface with a battery pack attachment portion at least partially surrounded by a battery-facing opening. A front opening is defined in the housing and is in fluid communication with the battery-facing opening. A rear opening and a lateral opening are also defined in the housing, between which charging electronics are disposed. The lateral opening is in fluid communication with the rear opening. The lateral opening is disposed at a location along a length of the housing between the front and rear openings. The battery-cooling fan is disposed between the battery-facing opening and the front opening. A duct forms a discrete flow path between the battery-facing opening and the front opening. An electronics-cooling fan is disposed in the housing between the rear and lateral openings.
