You know that sinking feeling with you turn your ignition key and nothing happens – usually a sign that your battery is dead.

You can avoid a flat battery by:

• Making sure you turn your lights off
• Turn off lights in other places like foot-wells and boots that operate automatically when glove boxes and boots are opened
• Don't leave your key switched to the auxiliary position – eg to run the car radio – for too long
• For cars without keys, keep the proximity sensor well away from the vehicle
