Abstract (en)
[origin: EP0390070A2] The present invention is directed to an electrode construction of a battery (1) in an electrical equipment. According to the present invention, at least two contacts (8a, 8b; 5a, 5b) in an electrode (4, 7) have a different shape from each other, so that the characteristic frequencies of these contacts are different from each other. As a result, when a contact is resonating by the frequency of an oscillation applied to the electrical equipment, the other contact keeps in contact with the battery (1) without resonating.
