Some cars have negative jump-starting poles - check your handbook to see if yours does. Do the same for the other end of the lead for the flat battery. At Halfords we offer a free check-up, cheap fitting service and a massive range of affordable batteries.
How to jump start a car using jump leads Park both cars in neutral next to each other so that they're close but not touching. To place an order our checkout relies on cookies. Remove the jump leads in reverse to the way you attached them. If you can't get the engine to start, unfortunately you have a bigger problem! We can also check your battery for you!
