Halfords Heavy Duty Booster Cables

BEST BUY Definitely the best set in the test. The clamps are very different to any of the others in the group. Although they’re well made and fully insulated, they’re much sleeker – which makes connecting them to the flat battery a far easier task. Electrical efficiency is good, and these leads are rated to deal with petrol engines with a capacity up to 5.5 litres (3.5 litres diesel).
