Feeling Flat…. leap back into life with a handy guide on how to use Jump Leads

Coming out of lockdown will have its own issues for your vehicles battery if it’s not been started for last few months. Jump starting your vehicle is a handy way to get motoring, but it comes with some safety precautions, as it can damage both vehicles. So if you are in doubt drop us a call and we’ll help, better to be safe than sorry!!

But for those that are keen to give it a go, here’s a quick guide the what you need and what steps to follow:


What you need:

  • A pair of working jump leads.
  • The vehicle with the flat battery, which needs to be in a spot where jump leads can easily reach the battery.
  • Another vehicle with a fully-charged battery (avoid a hybrid or electric car as this could cause damage).


Safety First:

Before you try to jump start a car, remember that batteries produce flammable gases. Check the battery and jump leads:

  • Never try to jump start a battery that looks damaged or is leaking.
  • Don’t use jump leads that are damaged.
  • Stop using the jump leads if they get hot.

Make sure the environment is safe:

  • Remove any dangling clothing as it could get caught up in the moving engine parts.
  • Don’t let any metal objects touch the car batteries – these could cause a spark and possibly make the battery explode. That includes rings, necklaces, watch straps, hand tools, clips, stray wires etc.
  • Never smoke or allow naked flames anywhere near either battery.

Take care removing the jump leads:

  • Don’t remove the jump leads while the car engines are running. This can cause serious damage to the cars’ electronics.


Steps to get your engine started:

  1. Line both vehicles: park both vehicles so their batteries are within easy reach of each other BUT not touching, with handbrakes on and ignitions off.
  2. Connect the RED lead to the working battery’s (+) terminal then to the flat battery’s (+) terminal.
  3. Connect the BLACK lead to the working battery’s (-) terminal then the other end to an earthing point (unpainted metal on the engine block or chassis) well away from the flat battery and fuel system.
  4. Start the working vehicles engine and let it run for 1 minute.
  5. Start the vehicle with the flat battery.
  6. Leave both vehicles to run for about 10 minutes.
  7. This will be long enough so turn both vehicles off and disconnect the leads in the reverse order that they were connected, making sure the leads do not touch.
  8. Restart the vehicle that had the flat battery, if it still doesn’t start there is likely something more serious so call for help!
