Abstract: A battery charger and a method of operating a battery charger. The charger may include a housing defining an air inlet and an air outlet; a charging circuit operable to output a charging current to charge a battery couplable to the battery charger; a tubular heat sink; and a fan operable to cause air flow from the air inlet to the air outlet and along the heat sink. The charger may include a first switch operable to electrically connect the charging circuit to a power source when the battery engages the charger; and a second switch operable to electrically connect the charging circuit to a battery terminal after the charger terminal is electrically connected to the battery terminal. The charging current or a fan speed may be adjusted based on at least one of the temperature of the charger or a temperature of the battery.

Abstract: A battery pack including a housing having a first portion and a second portion coupled to the first portion. The first portion has a first wall and an interface extends from the first wall. The interface includes a plurality of terminal apertures that provide access to electrical terminals within the housing. The second portion has a second wall, and the second wall is positioned opposite the first wall. A first plurality of vents extends through the first wall and a second plurality of vents extends through the second wall. A cumulative surface area of the first plurality of vents is different than a cumulative surface area of the second plurality of vents.

Abstract: A battery charger may include a printed circuit board (PCB) having a first portion supporting alternating current (AC) electrical components and a second portion supporting direct current (DC) electrical components; an indicator including a light-emitting diode (LED) supported on the first portion of the PCB and operable to emit light; and an isolating member positioned on the first portion between the AC electrical components and the LED. A trace on the PCB may be electrically connected to the second portion of the PCB, the trace extending from the second portion and along the first portion, and the LED may be electrically connected to and receiving DC power through the trace, the LED being selectively positioned along a length of the trace. The LED may be positioned more than about 8 mm from the AC electrical components.

Abstract: An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.
