5 Best Jumper Cables For Reviving A Dead Battery 2018

​Is there a more disheartening feeling than turning your key and just hearing the faint ‘click’ of a starter solenoid without enough power to engage the starter? Or perhaps listening to engine just turnover at about one revolution per minute? No there surely isn’t, and of course, it only happens when you’ve driven somewhere, nowhere near home. A manual car can be bump started with a little persuasion, but an auto? You need a set of quality jumper cables.

​If you’re lucky, you can buy a set of these cables and place them in your trunk tidy and forget about them, never having the need for them personally, although they do give you the opportunity to play good Samaritan should your neighbor ever find themselves with a flat battery.

​But what sort of thing should you look for ​the best jumper cables?

jumper cables considerations

​Any high-performance jumper cable, or even just … run of the mill jumper cables … are made from copper wire, that’s because it’s one of the best conductors of electricity. They’re made from a multitude of individual strands​, the bigger the wire, the more load it can handle, for sustained periods – a smaller or thin jumper cable won’t be able to take much load before it gets really hot. The reason for the many strands is simple – one thick strand wouldn’t be flexible and effectively, you’d be getting a metal bar that can’t bend or move, and that just isn’t practical.

​You should give thought to the length of the cables – anything too short will make it difficult to place the cars to connect, in this case, bigger is better, but of course … the longer the cable, the more copper and the higher the price.

​If you’re looking to start a small compact, then lightweight jumper cables are fine, but anything with a bit more get-up-and-go or diesel will require a cable that’s capable of delivering a higher load capacity, so again, the thicker the better.

​Our Top Best Jumper Cables ​Reviews 2018

​I’ve compiled a list of five of the best car jumper cables, although one is a permanent solution rather than a quick fix. It’s worth knowing that ‘1 Gauge’ wire is thicker than 10 Gauge, but the calculations aren’t straightforward, so we won’t be getting in to wire thickness, other than referring to gauge – a thicker wire can carry more load or current, meaning jumping a car should take less time, or that you can boost a really heavy-duty battery.

​1. Energizer 1-Gauge ​Heavy Duty Jumper ​Cables

Energizer 1-Gauge 800A Permanent installation kit Jumper Battery Cables with Quick Connect plug 30 Ft Booster Jump Start ENB-130-30' Allows you to boost a battery from behind a vehicle!

​Yes, this kit is expensive for jumper cables, but you’re getting more than a weak set of clamps and thin wire strands, these are designed for the professional user – own a tow truck business? These are for you.

​Made from one gauge wire, these heavy-duty jumper leads can carry a maximum load of 800 Amps (again, calculations give differing results dependent on load test, but a typical truck battery will run around the 600 Amp mark), so Energizer 1-Gauge​ will be able to jump start just about anything you come across.

​They use a copper clad aluminum, which in theory, means that you’re getting the best of both worlds – the light weight of aluminum and the conductive capacity of copper, either way, they remain flexible right down to -40 degrees centigrade, but still weigh-in at a heavy 10.35 pounds.

​The best thing about these cables is the length – 30ft is more than enough to not have to move cars around, you can pull up behind the dead car and still reach the battery.

​Another nice little touch is the Quick Connect – once you’ve installed the socket on your tow truck, you can literally just plug in to the socket for a fuss free connection.

​If you’re looking for the ​best heavy duty jumper cables, you’ve found them.

​2. CARTMAN Booster Cable 4 Gauge

CARTMAN Booster Cable 4 Gauge x 20Ft in Carry Bag (4AWG x 20Ft) UL-Listed

​Similar to the Energizer, the​ CARTMAN booster cables use a copper coated aluminum wire to transfer the power, but ​​come with a 4 Gauge wire​. The wires are coated in T-Prene which helps them to retain flexibility down to -25 degrees centigrade.

​The clamps use a patented design to ensure a secure connection to the battery terminal. Although it must be said that the springs in the clamps feel pretty light, but Cartman do offer a full 5-year warranty on the product.

​With 20ft of wire, the options for hooking up to another vehicle are many – you don’t have to be nose-to-nose, these will do nearly everything aside from straight behind the vehicle.

​​Everything comes neatly packaged in a bag, and includes the jumper cables, gloves and a wire brush for cleaning the battery terminals.

​For the money, they’re worth ordering to just leave in the trunk of your car, a great set of ​booster cables.

​3. Energizer 2-Gauge ​Jumper Battery ​Cables

Energizer 2-Gauge 800A Jumper Battery Cables 20 Ft Booster Jump Start ENB-220

​These jumper cables are nearly identical to their more expensive counterpart already listed, except that instead of the one gauge wire, they use two gauge and they’re 10ft shorter. The cables still have an 800 Amp rating, will remain flexible in all but the most harshest of winters, and feature super strong clamps that will never form a weak connection.

​The ​Energizer 2-Gauge cables don’t come with the Quick Connect system. They have clamps at either end, but that’s really only a useful feature if you’re running a breakdown service​.

​The​se heavy-duty jumper leads would be my choice for everyday / semi professional use.

​4. Iron Forge Tools ​Jumper Cables

Iron Forge Tools 20 Foot Jumper Cables with Carry Bag - 4 Gauge, 400 AMP Booster Cable Kit

​Again, this price point makes the quality of these cables an excellent choice for throwing in the trunk and hoping that you don’t need them, but safe in the knowledge that if you do, they’ll work exactly as you need them to.

​The Iron Forge Tools jumper cables use a 4 Gauge copper coated aluminum wire that’s rated at 400 Amps, and being 20ft in length, you shouldn’t really have any access problems. Better still, the clamps are well designed and have a strong spring mechanism – these will always give a great performance.

​Unusually, Iron Forge Tools have a lifetime warranty for a replacement – they’re so confident in their product that they’ll replace any defective item with a brand-new item​.

​Definitely my choice for the cheap jumper cables.

​5. Performance Tool W1673 ​Jumper Cables

Performance Tool W1673 20' 4-Gauge 500 AMP All Weather Jumper Cables

​These jumper cables from Performance Tool sit in the mid-range of pricing, and while they don’t seem to offer that much more than the Iron Forge Tools cables, they do the job well.

​As with all the other cables here, they’re copper coated aluminum, using a 4 Gauge wire which has been rated at 500 Amps continuous, with a peak load of 600 Amps – more than enough for all but the biggest of motors.

​The clamps use a strong spring to ensure proper connectivity, and the cables have a thick PVC coating to avoid damage. For some, the PVC is less attractive than traditional rubber, but even so, they remain flexible in harsh climates – the coating shouldn’t crack or retain kinks.

​20ft in length should give you all you need, although trying to jump a car from behind it is almost impossible unless it’s a small compact.

​Using Jumper Cables

using jumper cables

​Jumper cables are easy to use, you’re effectively linking two cars together, or borrowing the battery power from another car.

​The correct way to use jumper cables is as follows.

​With the engine off on both cars, and in neutral or park, you should attach the red or positive clamp to the failed battery first, then to the live battery.

​The black or negative lead should be then clamped to the good battery, followed by a large metal part on the dead car – you should avoid attaching it to the other battery because when it closes the circuit, it may spark, which in theory, could ignite battery gases.

​Be sure to clamp it to an ‘earthed’ point on the car – a weak earth could cause the lead to heat up significantly.

Note: 6V systems aren’t so common now, but if it’s an old vehicle, there is a chance that it could be 6V rather than 12V, you should always check battery voltage before connecting the jumper leads.

​It’s worth identifying just why the battery drained – leaving your lights on is one thing, but if there’s no obvious cause, you should get the battery checked, or consider purchasing a battery tester or multimeter.

​Never Leave Home Without Jumper Cables

​If you drive an auto transmission, a set of quality jumper cables is an essential part of motoring. You really should never leave home without them, and when you can pick up a set for the price of a few cups of coffee, you’d be crazy to not consider it.

​You don’t need to invest top dollar to get a quality product, and having some jumper cables to hand may even give you the chance to play a hero to someone, and that’s a great feeling!

​Any of these five jumper cables are worth your money, although the Energizer permanent ones are really aimed at the professionals, but looking from a different angle – if you’re the outdoorsy type, then being able to run a battery cable to power something easily is an added bonus!
