How do you start a car with a dead battery?

My mate's Rover 75 won't start. It keeps making a clicking sound when he turns the key and his battery has gone completely flat. It wont start and you can't bump start it because it's an automatic. Do you have any suggestions of how to get it going?

The first thing to do is check the car's battery. If the battery is ok, then it could be the ECU. The 75 is notorious for an ECU fault that masquerades as a dead battery. The ECU is located near the windscreen's drainage holes on the passenger side under a plastic cover. The drainage holes get blocked by dirt and debris and then the ECU gets damp, causing the car to 'click' but not start.
