Apparatus having at least one battery secured to a printed circuit board

An apparatus comprising a printed circuit board (14) and at least one battery (12, 13) mounted on a surface of the printed circuit board (14), which said at least one battery is intended for powering the apparatus and has two terminals (15, 16, 17, 18), provided on at least one surface of the said at least one battery (12, 13), each terminal provided with a solder lug (19, 20, 21, 22) which is fixedly connected to a mounting portion (23, 24, 25, 26) of the printed circuit board (14) by means of a solder joint (27), which mounting portions (23, 24, 25, 26), situated on a surface of the printed circuit board (14), can be severed from the remainder of the printed circuit board (14) to enable the said at least one battery (13, 14) to be removed from the apparatus, characterized in that each mounting portion (23, 24, 25, 26) of the printed circuit board (14) is surrounded by the remainder of the printed circuit board (14), and is partially separated therefrom by an opening (28, 29, 30, 31) formed in the printed circuit board (14) between each mounting portion (23, 24, 25, 26) and the remainder of the printed circuit board (14), which opening partly surrounds the relevant mounting portion (23, 24, 25, 26) and which opening 28, 29, 30, 31 has two ends opposing (32, 33;

• 34, 35;
• 36, 37;
• 38, 39), and each mounting portion (23, 24, 25, 26) is connected to the remainder of the printed circuit board (14) by a connecting portion (40, 41, 42, 43) of the printed circuit board (14), which connecting portion is situated between the two ends (32, 33, 34, 35, 36, 37, 38) of each opening (28, 29, 30, 31), which mounting portions (23, 24, 25, 26), which are each situated within an opening (28, 29, 30, 31), can each be severed from the remainder of the printed circuit board (14) substantially at the location of a connecting portion (40, 42, 42, 43).
