Clarke CJL25C
Price: £27.01 Length: 3.5 metres
At first glance, these leads look the same as Clarke’s other offering. But it’s their beefed-up 25mm copper cores that boost electrical efficiency, and the rating has been upped to allow use on petrol engines to a capacity of 5.5 litres, or a maximum of 3.0 litres on diesels. We like the tough zip bag they’re supplied in, but, again, the clamps are a little too bulky to allow easy connection.
