There are your run-of-the-mill jumper cables, and then there are the professional grade and heavy-gauge, heavy duty jumper cables. These jumper cables can be permanent jumper cables and are designed for heavy loads and to be able to handle heavier cranking power.

While this is a must have for any driver or vehicle owner, the reality is that this is rarely used. For this reason, one must invest in heavier-gauge, extra thick, as well as extra Long cables for that peace of mind.

Why heavy-duty? Simple, the cables you choose can pretty much outlive the car itself when chosen carefully.

Heavy Duty Jumper Cables Buying Guide

Cables are pretty much just wires right? Why a guide? The problem is that the market is saturated with items claiming to be the best heavy duty jumper cables. Obviously we cannot just buy anything just because the seller says they are great, so we did the hard work and came up with a list that you can use as a tick box below.

Clamps

Let’s face it, even 30 ft jumper cables will not be of any use if the clamps that go with them are of questionable quality. Therefore pay attention to how the clamps are made. These should be sturdy, with enough clamping force so that they fit snugly on the terminals. Loosely attached cables can damage your vehicle’s ECU and can also become quite dangerous as they can lead to sparks. They come in several types, but the most common by far are parrot clamps and alligator clamps. Parrot clamps are shaped like a parrot's beak and are more compact, while alligator clamps are larger but because they have grooves or teeth, they give a much stronger clamping force.

Durability

The best, extra heavy and big jumper cables should be extra durable as well. These cables should be able to withstand the wear and tear when operating near heavy machinery. Look for the heaviest jumper cable gauge meaning the biggest practical size for your needs. DUrability for these cables usually equates to their jackets or cover. The cover should not be just plastic, but also contain rubbery material for a tougher combination.

Thickness

Heavy duty and spartan power jumper cables should have just enough thickness for ease of use and flexibility. Check for the gauge of the wire and make sure you inspect the insides of the wires near the terminal connectors. Thicker and higher gauge cables means that they can allow much more powerful cranking power, such as what is needed in heavier vehicles. Also ensure that you also allow for the thickness of the cable’s sheathing, as sometimes the jacket is too thick while hiding flimsy wiring within.

Length

The average jumper cable should be in the vicinity of 12 feet in length. However, while this length is good enough for small passenger cars like sedans, this would never do in dealing with bigger vehicles such as trucks and heavy-duty equipment. Look for jumper cables with at least a 30 foot length to ensure that it will be enough to reach between two large vehicles. Always remember that the length should be enough for two vehicles parked side by side.

Power

Power here refers to how much amperage and electrical energy can be handled by the wires themselves. With this, ensure that you are getting the right gauge for your vehicle's electrical system. A good starting point would be not to go below 1200 PA (Peak Amps) and 225 cranking amps. This can be easily verified through the product’s spec sheet.


We never want to give you incomplete information, so here are questions that most people looking for heavy duty jumper cables ask.

Frequently Asked Questions (FAQs):


How to properly connect the jumper cables?

Aside from the polarity there is a general rule when it comes to the sequencing of the connections. While it is still a hot debate, the general consensus in the automotive community is to connect the positive terminals first.

This means the red wires in the color coded wiring. Next up would be connecting the black cables (the negative polarity wire).

As soon as the connections are secured, try starting your vehicle. Of course, prior to all this, make sure that it is the battery indeed that is wrong with the car you are about to start.


How long should jumper cables stay on?

Jumper cables should stay on about a couple of minutes after the vehicle with the depleted battery has run for about two minutes.

Make sure that you remove the car jumper cables in the reverse order that you put them on, Which means getting the negative side off first.


Should jumper cables spark?

Sparks should be normal especially if the donor battery is newly charged or has a full charge. A little spark is usually indicative of a healthy battery and should be no cause for alarm. Excessive sparks though are not normal and should further be checked.

Conclusion

Heavy duty jumper cables are a necessary accessory to anyone who drives or owns a car. This may mean being stranded by the side of the road or getting home safely to your loved ones. Although the market is full of jumper cable products, we hope that the information above will help you make an intelligent decision when it comes to purchasing this vital tool.
