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: A temperature controlled enclosure that includes a temperature control device for controlling the temperature within an internal cavity of the temperature controlled enclosure. The temperature controlled enclosure also includes one or more charging ports for receiving and charging a battery pack. A controller within the temperature controlled enclosure controls the temperature within the internal cavity to a predetermined or desired temperature (e.g., 20° C.). When a battery pack is received in the one or more charging ports, the temperature of the battery pack can be determined. If, for example, the temperature of the battery pack is below 0° C., the battery pack is allowed to warm up inside the temperature controlled enclosure before the battery pack is charged.
