Cinch-Lock Technology

Cinch-Lock clamp features

No more fighting with too-tight, spring-loaded cable clamps. The Hopkins Cinch-Lock clamps ratchet in place on the battery posts for a secure grip that is simple to obtain. Just squeeze the rubber-coated, non-slip grips, and the clamps will ratchet down until they can ratchet no more, at which point they effectively lock in place. To unlock, just push the convenient easy-release button at the base of the grips, and the ratchet will give for quick, effortless removal.


These unique Cinch-Lock clamps are constructed of premium, zinc-plated steel that can withstand more than 200 lbs of bite force and provide 250 percent more clamping force than the competition.


How to Jump-Start Your Vehicle's Battery:

Before jump-starting your vehicle, check the dead battery to make sure that it isn't cracked or frozen. If it is, do not attempt a jump-start. If there is no obvious damage to the battery, continue with the following:


  1. Turn off the vehicle that is providing the jump. Unplug all accessories from both vehicles. This will ensure that no devices are damaged if a short occurs.
  2. Clean off any corrosion around the battery terminals so that the maximum amount of current can travel through them.
  3. Connect one of the orange, positive cable clamps to the positive terminal on the dead battery.
  4. Connect the other orange clamp to the positive terminal on the good battery.
  5. Connect one of the black, negative cable clamps to the negative terminal on the good battery.
  6. Ground the other black clamp on the the vehicle in need of a jump - attach it to a clean, unpainted metal surface on the engine block or frame. Do not attach the negative clamp to the negative terminal of the dead battery.
  7. Start the vehicle that is providing the jump and let it run for a few minutes.
  8. Try to start the dead vehicle. If the engine does not turn over, rev the engine of the good vehicle to boost power output.
  9. Remove the clamps in the reverse of the order in which you attached them, being careful not to touch the clamps together as you do so: Disconnect the negative from the engine block or frame, then the negative from the good battery. Disconnect the positive from the good battery, then the other positive from the bad battery.

Video Transcript for Hopkins Super Duty Jumper Cables Review

Speaker 2: (music) Today we're going to review part number HMBC0840. This is the Hopkins Super Duty Jumper Cables. A couple of quick things to know is that the cable length is going to be 16 feet long. The wire gauge, or thickness of the cable is going to be a 6 gauge material. We're going to take a look at the clamps. First off, you can see how they're squeezed together.

The ratchet's holding it in place. To unlock them, push down on that button right there. That releases the ratchet, and you can open them up. Then when you put them on your battery terminal, squeeze them down tight, and they'll stay in place. You can see we have some alternating colors here. The orange color is going to be for a positive terminal.

Next he has a marking for that on the clamp. Our black one, of course, is going to go to the negative terminal. The handle assembly itself is all covered in a rubber-like material so it gives a good, easy grip. When you clamp down on it, your fingers won't slip. I got gloves on. I still can get a good grip on it. If you look back here you can see the ratchet assembly.

To close it, you can hear it ratchet. Stays in place. Take a look at the jaws real fast. Jaws themselves are steel, with zinc plating on it. You can see on the inside there, at the end of the 6 gauge cable, where it's fastened to the inside of a jaw. Take a closer look at the jaw, you can see the different type of pattern on the sides and the front. It allows you to work with different type of battery posts.

Either a top post or a side post type of battery. One last little detail, that the booster cables do not come with a bag. This, you can probably reuse the box. May I suggest this Part number ETBNB. This is the eTrailer, ballmount bag. If it's strong enough to hold a ball mount, it should be plenty enough for your cables. Take and make everything as compact as possible. We'll just clamp the cable ends together. Put the clamps into the bag first. Then our cable on the inside on top. There you go. It's just a little bit of room to spare. Go ahead and try them out in a typical application. First, off a green card, you'll want to bag batteries. You take an orange cable and connect it to the positive side of the battery. Squeeze it down until it touches, then squeeze it just a little bit more. You've got a nice good connection. We'll go over to our truck with the good battery. We'll go ahead and hook up to the positive side, on our good battery. We'll do a different location. OK. Then we can go ahead and hook up our black cable to the negative side. Ah, ha, there you go. On the car with the bad battery, go ahead and take the black clamp. We're going to ground this to the engine block or to the body work. There's a variety of places you can do it. This exhaust bolt is going directly to the block. You can attach it there. Maybe on the bracket by the alternator, you can do that as well. Let's just see this guy, huh I think for a demonstration we'll go to this bolt here. With 22 vehicles we have plenty of extra cable length. Go ahead and start the vehicle for a good battery Then we'll start our car with the battery. (car engine starting) We're done. Let's go ahead and disconnect them, in reverse order. (music) Then we ca go ahead and do your positive cable. All right, with that, that will finish for a review of the Hopkins Super Duty Jumper Cables, 6 gauge material, by 16 foot long, card number JMDC0840. (music).

The cables I was looking for. Nice thick wires and the clamps ratchet down to lock in place. Construction seems solid enough. 465417

Pretty unsatisfied with the design of this product - the clamps require two hands to hold the locking button down (right next to the metal teeth) while opening the clamps. Then, the clamps don't open wide enough to sit firmly on the battery contacts. The cables seems to be heavy duty and of good quality, but the locking design is poor. 585355

Ask the Experts about this Hopkins Jumper Cables and Starters

Do you have a question about this Jumper Cables and Starter?


  • Wire Gauge and Current Capacity in 12V Systems
  • The appropriate wire gauge for any given amperage application depends on the length of the wire. A longer wiring installation may need to be a heavier gauge to compensate for voltage drop. To support 40-amps in a 12V system 20-feet of wire should be 6-gauge, like the Hopkins Super-Duty Jumper Cables # HMBC0840. A 10-gauge wire can support 20-amps up to a 15-foot length. There are tables available online to help determine the wiring compatible for any power requirement. I sent you...

  • Troubleshooting 4-pole Wiring on Haulmaster Trailer
  • Since you've tested the 4-pole harness on your 2012 Chevrolet Sonic and found it to have the correct lighting signals you can start your trailer troubleshooting at the main ground wire that connects to the trailer frame. This white wire's ring terminal needs to make solid contact to a clean bare metal spot on the frame, one that is free of paint, primer, rust and grease. Since none of your trailer light circuits work it is likely that the ground or a bad connector is the cause. You can...

  • Process for Testing Caravan Wiring for Determining Function on Each Wire
  • Yes, you can use a process of testing your wiring with a circuit tester to confirm what electrical function each one carries. Wire insulation color is not a reliable way to know what that wire does so a probe tester like # PTW2992 is the best way to eliminate guesswork. You can refer to the linked video to see how the tester is used. When testing a vehicle it is easiest to have a helper activate a function while you test the wires to find the wire that carries that function. For instance,...

  • Troubleshooting Turn Lights on Utility Trailer Towed by 2016 Nissan Rogue
  • Troubleshooting trailer lights is easiest if you disconnect the trailer from the vehicle and check each individually. On the Rogue you can use a simple circuit tester like # PTW2992 or the item # 40376 that you referenced to see if the on-and-off blinking signals are present on the contacts for the turn signals. On 4-pole wiring these will be the pins furthest away from the exposed ground, the pins for the green and yellow wires. On 7-way wiring the contacts to test for turn signals are...
