ABSTRACT:
A power supply unit for portable apparatus. The battery of rechargeable cells is provided with a connector designed to co-operate with a first connector when said battery of rechargeable cells is placed in said cavity. The power supply unit further includes a removable part serving as an electrical interface between said set of at least one non-rechargeable cell and the first connector, when the set of at least one non-rechargeable cell is placed in the cavity, the removable part being provided with another connector designed to co-operate with said first connector. According to the invention, the removable part can take up the following two positions inside said cavity: a passive position when the battery of rechargeable cells is placed in the cavity, in which position the part does not serve as an electrical interface relative to said first connector; and an active position when the set of at least one non-rechargeable cell is placed in the cavity, in which position the part serves as an electrical interface between said set of at least one non-rechargeable cell and said first connector.
