How long it takes for the Battery Brain to disconnect?
It depends on the battery condition, if it’s a used battery, the Battery Brain will disconnect the load from the battery in a shorter time then in a new one. It also depends on the amount of load that was left on while the engine was not running. In any case it will save the driver from getting stuck without the ability to restart the car. The Battery Brain will not disconnect the load from the vehicle battery while the engine is in normal operation.
