Abstract
A battery charger is provided with a connecting part for connection of a rechargeable battery in a freely removable fashion. The charger body has charger terminals protruding from the connecting part to electrically connect with battery terminals of the rechargeable battery. The connecting part of the charger body has a body slot and catch to allow connection thereto of only a particular rechargeable battery. The slot and catch of the body are designed to match with a battery slot and catch of the rechargeable battery when the appropriate rechargeable battery is normally connected to the connecting part, but to not match with the battery slot and catch when the connecting part of the rechargeable battery is abnormally connected. Both catches of the battery slot and catch and of the body slot and catch are provided to protrude at a location facing each other to prevent the electrical connection of the terminals when the battery slot and catch and the body slot and catch do not match each other.
