Prestige Guide To Using Jump Leads Safely

Nobody likes discovering that their car is refusing to start, but wouldn’t you like to know how to deal with it if this does occur?

Rest assured, here we have provided a small guide to help you jump start your car safely and correctly.

If you are unsure that it is your battery that has failed, there are a couple of things you can check:

  • If the headlights appear dim then it is most likely your battery is at fault
  • When trying to start the car, if it doesn’t crank or cranks slowly then you more than likely have a dead battery

Jump starting your vehicle can be dangerous if not done properly so if you do believe that the battery is the problem, here are a few hazards you should be aware of before you begin:

  • Damaged Jump Leads – these can easily overheat, which could lead to a fire.
  • Metal Objects – these should be kept at a safe distance as they can cause sparks with the battery risking damage to your car and putting you in danger.
  • Smoking or Naked Flames – avoid smoking or having any other naked flames near the vehicle as the gases given off by the battery are flammable, making this highly hazardous.
  • Loose Clothing – you should be aware of loose or baggy clothing as they can get caught on moving parts when the engine is running, putting you at risk of injury.
  • Damaged Battery – if the battery itself is damaged or leaking you should not attempt to jump start the car yourself as it can cause an explosion!

If you are uncertain about any of these hazards, please give Prestige Vehicle Repairs a call, 01708 868864. We are always happy to help.

Now, here’s a small guide to help you with the process of jump starting your vehicle:

  • To start off you need to ensure that the vehicle you are using to help jump start your car has the same voltage
  • Both vehicles should have the handbrake on and the ignition switched off and key removed – ensure that the vehicles are close but not touching
  • Open the bonnets of both cars and locate the battery
  • Connect the red jump lead to the positive terminal (+) of your battery
  • Next, connect the black jump lead from the negative terminal (-) of the other vehicle to a suitable earthing point on your vehicle, away from the fuel system and battery, on either the engine or chassis of your vehicle (i.e. a nut or bolt) – some cars have negative jump starting poles, this can be found in your handbook
  • Ensure the cables are not dangling over moving parts as they could get caught up
  • Wait for the voltages to equalise (To equalise a battery, means the charging is allowed to continue well after the point at which the battery is normally considered to be “full”) and then start the engine of the other vehicle, leaving it to run for a minute then attempt to start your engine
  • Once your car is running it is ideal to leave your engine on for a few minutes to charge the battery
  • You can then disconnect the jump leads in the reverse order to which you connected them whilst ensuring that the clips do not touch each other or any metal surfaces

We hope this guide helps, however, you should always check your vehicle’s handbook before performing a jump start as some vehicles require specific procedures to that particular model. Ensure to follow the instructions listed in the handbook if this is the case.
