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 and a method for connecting a battery pack to an electronic device to power to the electronic device (e.g., a headlamp, a flashlight, a flood light, a drill, a driver, etc.). The battery pack includes a generally cylindrical housing defined by an arcuate sidewall extending between a first end surface and a second end surface and defining an interior cavity configured to support at least one battery cell (e.g., a lithium-ion battery cell). The battery pack includes a first insertion alignment member engageable with a first battery alignment member of the electronic device in order to facilitate insertion into a receiving portion of the electronic device in a first direction and a second insertion alignment member engageable with a second battery alignment member of another electronic device in order to facilitate insertion into a receiving portion of the other electronic device in a second direction.
