Short description

With its patented digital monitoring system, the Cadillock Classic constantly checks the minimum voltage level that the vehicle battery must maintain to be able to start the car. As soon as the voltage has fallen short of 11.9 V for a period of more than 60 seconds, the Cadillock Classic automatically interrupts the vehicle power supply.

Thus the Cadillock Classic protects your vehicle's battery from falling to a dangerously low state of charge or even being completely discharged, and reserves the necessary battery energy for an engine emergency start. Thus the Cadillock Classic prevents your vehicle not being able to be started due to a flat battery. 

The anti-theft device is activated via the remote control. The Cadillock Classic cuts off the entire battery power supply and thus makes it impossible to start the car. 

By interrupting the power supply by the Cadillock Classic the status of the car battery is very similar to the state that would be achieved by disconnecting the car battery. In other words, not even the slightest amount of electricity is available.
