Take the existing battery out of the car, connect one end of the jump leads to the battery and the other to the battery terminals in the car (being careful not to let them earth) and try to start the car. That'll tell you if they'll work.
You could also measure the voltage across the battery with the engine running to see if the system will charge properly.
