Zusammenfassung:	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.
