NOVELTY - The battery (10) has two battery cells (20,21), and a first electrical connection (30) for connecting respective poles of the battery cells. A second electrical connection (40) branching off from the first electrical connection, is used for measuring battery cell voltage of the battery cells. The second electrical connection is provided with two sections (41,42) that are configured for different maximum current magnitudes.    USE - Battery such as lithium ion battery, nickel metal hydride cell, lithium metal polymer cell and lithium polymer cell for motor car (claimed) such as electric or hybrid motor car. Can also be used in small portable electronic device such as mobile telephone, laptop, camcorder, power tool, and MPEG audio layer-3 player.    ADVANTAGE - One of the sections of the electrical connection is configured as a fusible link that melts in the presence of a melting current magnitude that lies between the different maximum current magnitudes. Thus, in comparison to using individual fuses, a safety fuse is provided in the cell monitoring system in a cost-effective and simple manner, so that the connection is separated in the event of a short circuit. The fusible section can be accessed in order to perform a visual inspection. Thus, the other section can be encased in a synthetic material casing and the fusible section can remain uncovered, so as to improve the separating effect. Even if the separating effect is interrupted as a result of a voltage flashover after a first fusible section has melted, the melting of the first fusible section causes the other fusible section to melt. Any further voltage flashover is then reliably prevented as a result of the length of the section lying between the fusible sections. An increase in expansion of the fusible section in the main direction of expansion can reduce the number of voltage flashovers between the sections after the fusible section has melted.
