JP-6 1200amp 6 Metres Professional Jump Leads Heavy Duty Booster Cables

I originally hada 3m long set, but soon found this too awkward in some cases, regarding overall reach. This set is 6m in length and is much better for it. The copper inside the cable is 25mm sq', so it is the same as light duty welding cable you get with small welding sets etc. However, it is quite up too the job of helping a battery on a car to turn the engine over. The copper core is clamped too the spring loaded clip, which is itself a beefy item. The outer covering of each cable is then clamped further back along its length. This gives a good connection overall. I found it easier to handle these cables if they are taped together by ducktape, every 15" or so. This gives in effect only one cable to handle and coil up to put it back into the plastic bag, rather than two thick cables which can be awkward to manouver back into the plastic bag they come in. I highly recommend these cables for their build quality and length, though you can make your own cables up (at extra cost of course) using seperate clips and welding cables of any length required. In that case you may need thicker cales for lorries or other very large machinery etc. I would recommend possibly using 50mm sq welding cable if needed in such cases, to carry any extra loads.

I purchased these jump leads to use with my ECU remapping business and they have worked perfectly over the last few weeks. I mainly use them as a battery stabiliser when reading/writing to a vehicle’s ECU to maintain battery voltage. The jump leads arrived well packaged in a plastic zip up case. They are exceptionally long at 6m length which is exactly what I was looking for. The zip case is flimsy and is a tight fit so I struggled to get the leads back in to the case. However, I don't see this as an issue and prefer to have them in a tool box anyway. The build quality is excellent. The leads are heavy duty with 12mm thick cables and the clamps are the highest quality clamps I have come across on a set of jump leads. The cables don't tend to get tangled due to the thickness of them which is also a nice bonus. These jump leads are designed to jump start 6V, 12V and 24V batteries. I have only tried them on cars and vans but they should start trucks and large agricultural vehicles with the 24V capacity. Overall, I am very impressed with these jump leads. They are fantastic quality, good value for money and can jump start almost any vehicle you could possibly come across.

Good thick cables, feel quality but havent used them in anger yet, but cant forsee any problems.

It is well made cables, isolator around clipper was a bit broken, but it doesn't make any difference as it still was in place and covers clipper. wires is big enough to start car even with flat battery and bigger engine

this is a good sturdy product the cable length is great the only problem was the small bag it came in but other than that it works well

Really long and thick cable too, not just the insulation. Jumped my van without the cables even getting warm. You don’t need to park nose to nose to reach either. It’s 6m long each side, not in total.

Had to use them several times before the battery could be replaced. Excellent size which meant no tricky manoeuvring to get leads to stretch. Excellent purchase.

Bought these to jumpstart my transit van as I don't drive it often, these jump leads are great started the van first time. I like the carry case the leads come in, In all great product and great price.
