Abstract
A battery casing for attachment on an electric equipment having positive and negative terminal rods. The battery casing comprises positive and negative terminal plates exposed for connection to the respective terminal rods when the battery casing is attached on the electric equipment. The battery casing also includes a shutter mechanism for covering at least one of the terminal plates. The shutter mechanism uncovers the one terminal plate in response to movement of the corresponding one of the terminal rods during the course of attachment of the battery casing on the electric equipment so as to permit the one terminal rod to come into contact with the one terminal plate.
