Jump starting a car with leads

Before attempting to jump start a car with leads, always check your owner’s manual for advice. Some vehicles are not suitable for jump starting, and others may have special requirements. Electric vehicles and vehicles with complex electrical control units may not be suited to standard jump start methods. Never attempt to jump start a vehicle with a corroded, leaking or visibly damaged battery.


Your car can also be jump started with a specialised jump starter kit. You won’t be able to jump start with a battery charger, however it can replenish a fully dead battery within 24 hours. We recommend referring to your owner’s manual and the instructions on your equipment before operating.
