<p>The battery device (31) comprises a housing unit (33) having a cell housing section (32), dimensioned to hold at least two tubular cells (1 2 -1 4 ) in juxtaposition and parallel to each other. There is provided a hole (52) formed and extending inward at a position on the forward end face (41) of the cell housing section (32) which is not opposed by end faces of cells (1 2 -1 4 ) when cells are housed within the cell housing section, said hole (52) being formed at a position in the space which is delimited between cells (1 2 -1 4 ) when cells arranged in juxtaposition and parallel to each other are housed in the cell housing section (32). There is further provided a groove on a top surface of the housing unit (33) at a mid position along the width of the housing unit, said groove being opened in the forward end face (41) of the housing unit (33) and extending from the forward end face as far as a mid portion of the housing unit (33), the length of said groove in the longitudinal direction of the cell housing unit being greater than the depth (D 1 ) of said hole (52). The battery device (31) further comprises connection terminals (37, 38) for electrical connection to connection terminals provided on electronic equipment and the depth of the hole (52) is greater than the depth (D 1 ) of said connection terminals (37, 38) of said battery device.</p> |
