<p>In an anti-theft system for a motor vehicle having a battery supplying electrical power to enable the vehicle to operate, the battery has a built-in remotely-operable switch to interrupt or limit current flow between one of the battery terminals and the battery cells. The battery is of the conventional type comprising a casing (1) containing a plurality of electrical cells (2) and having external positive and negative terminals (3, 7). The battery cells (2) are connected to one of the terminals (3) directly and to the other terminal (7) through switching means (5) within the casing, the switching means (5) being arranged to close the circuit between the cells (2) and one of the terminals (7) in response to a control signal, a control means being provided outside the battery casing, and being operable to provide said control signal, for example as an infrared signal along an optical fibre cable.</p> |
