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 battery charger includes a housing having support structure for simultaneously supporting at least two batteries of different types for charging including a first battery of a first type and a second batter of a second type. The battery charger further includes charger electronics supported by the housing and operable to output charging current to charge the first battery and charging current to charge the second battery. A fan is operable to cause air flow through the housing. A fan speed of the fan is adjustable based on a temperature of the battery charger (i) while at least one of the at least two batteries is coupled to the battery charger for charging and (ii) while no batteries are coupled to the battery charger for charging.
