Auto jump — 1: Whether it's because you left the lights on or your battery is old, most car owners will be faced with a dead battery sooner or later.

Auto jump — 2: Then, park the second vehicle close to the car with the dead battery – get them close together so the jump leads will comfortably reach from one battery to the other - but make sure the two cars are not touching each other.

Auto jump — 10: After the leads have been removed, restart the engine on the casualty vehicle. The battery will need to recharge fully for it to be fully serviceable, which is best achieved using a quality battery charger for several hours. In the meantime, if possible, drive the vehicle normally (not in heavy traffic) for around 30 minutes to try to put some charge back into the battery. Image Credit: Shutterstock
