A battery compartment, an electronically driven dispensing unit and a dispenser

A battery compartment (1) for an electronically driven dispensing unit, comprising:

• an electronic unit comprising:
• a fixed first structure, the first structure comprising, for each of at least two cylindrical batteries, a first electrical connection and a second electrical connection positioned opposite each other, the first electrical connections being arranged on the same side of the battery compartment and the second electrical connections being arranged on the opposite side of the battery compartment;
• and
• an electrical bridge extending between the first and second electrical connections for serial connection of the at least two cylindrical batteries;
• and
• a battery holding unit having a fixed second structure adapted to, in a loading direction, receive the at least two cylindrical batteries side by side and adapted to contain the batteries in directions perpendicular to the loading direction
• wherein the first structure is adapted to receive the second structure and the batteries for connection with the first and second electrical connections, and
• wherein the second structure is rotatably connected to the first structure via a joint allowing rotation between a first open position in which the batteries are loaded or unloaded in the battery holding unit and a closed position in which loaded batteries are connected to the first and second electrical connections via spring action and movement of the batteries in the loading direction.
