‘It depends on your definition of “bad.” Obviously, it’s not ideal if they’ve corroded and you’re stuck with a messed-up connection. But cables don’t necessarily go bad; they can become less effective as time goes on, but only if the cables deteriorate enough to require replacement.
So cables can become less effective with time, but this is only if they deteriorate. The physical condition of the jumper cables is the biggest reason they will go bad. Corroded clamps, frayed wires, Cables can become less effective with time if their physical condition deteriorates
If your jumper cables are more than three years old or have been sitting idle, they may need an update. Look for corroded contacts as a sign that it’s time to replace them before the next use!
If corroded contacts cannot allow proper connection with the terminals of your car’s dead battery, you run the risk of not being able to jump-start your car successfully. So if you take care of them well and keep them free from corrosion, they should last a long time.
How Do I Know if My Jumper Cables Are Bad?
The best way to know if your jumper cables are bad is to give them the eye test. Inspect the physical condition of your jumper cables. Look for burn marks on the clamps, for instance.
|Signs of Bad Jumper Cables|
|Exposed wire- If you see copper, no good|
|Frayed Wires – Near the clamps, if wires are sticking out, no good|
|Corrosion – If you see corrosion on the clamps, no good|
Check for any frayed or exposed wires. The most obvious sign of wear is thin or ripped insulation. If there are exposed wires, you probably should think about replacing your jumper cables.
As was mentioned, you may also want to make sure that the clamps are still in good condition, not corroded or frayed, and that there’s no damage to any of the wires. If you can see any wear and tear at all, it’s time to replace the jumper cables.
It’s easiest to know if your jumper cables are bad by testing them before needing to use them for a jump start. If they connect properly, and there is no damage to any of the wires/clamps/etc., then you should be good!
Why do Jumper Cables Fail?
There is not a lot mechanically that can go wrong with jumper cables…unless they have surge protection or some other electronics attached to them. There is always the possibility that something like that will wear down with time.
Physical degradation is the prime reason that jumper cables will fail. It really depends on the quality of the materials that are used in the jumper cables.
One of the worst things that can happen is if one wire separates from the clamps. If this happens, it will be very difficult for you to continue to have a connection with your car’s battery terminals.
There is the possibility of sparks if the wires become separated. And when you have sparks you have the potential for fire or explosion. So if you see exposed or loose wire, think twice before using that set of jumper cables.
Jumper cables can last a very long time however when they are taken care of. I have had my set of jumper cables for about 10 years now. This leads to the question, how do I maintain my jumper cables?
How Do I Maintain my Jumper Cables?
A good way to maintain your jumper cables is by keeping them in a storage bag or box with extra room for air circulation and avoiding anything that could harm them like sharp objects or punctures.
This will help prevent any damage because you’ll be able to protect them from things like water exposure and debris. Just keep them clean whenever possible so they don’t corrode over time.
This is a lot easier than it sounds (it doesn’t even sound that hard). Most jumper cables come with their own storage container anyway. Just keep it in there.
Under your car seat or in the trunk would be perfect storage areas. After all, you are going to need them in your car, right?
The only place I might be concerned about storing my jumper cables would be an external toolbox or something like that. I don’t have one, but I have seen them collect moisture, which could ruin your jumper cables.
What should I do if my Jumper Cables Fail?
So you have done everything right, but still, somehow someway your jumper cables just aren’t working anymore. What should you do?
If your jumper cables fail, you’ll need to replace them as soon as you can because the chances of successfully jump-starting a car with bad jumper cables are very low. If you can’t find replacement ones right away, your best bet is to use another set of cables that are in good condition or borrow them from someone else.
If your jumper cables stop working, the chances of successfully jump-starting a car with bad jumper cables are very low! If you can’t find replacement ones right away, try to use another pair of cables that are in good condition or borrow them from someone else.
However, if you’re using another person’s jumper cables and there is no way for you to check their quality, don’t risk it—just replace yours as soon as possible. This will ensure that you have a much better chance at getting the job done right the first time around.
What Should I Do With Old or Broken Jumper Cables?
If you have any old, broken, or unused jumper cables lying around, just put them in the trash! They’re not very good for anything else, so it’s best to just get rid of them. Recycle them or strip them down to the wire for salvage.
Do jumper cables go bad? They can. They can wear down and break. The components can come apart. It may take a very long time, but it can happen.
Luckily, there are some simple steps to take to prevent these scenarios from happening and help your jumper cables last longer! Consider storing your jumper cables with ample ventilation and avoiding anything that could harm them like sharp objects or punctures.
You should also keep them clean as often as possible so they don’t corrode over time. If your jumper cables are beyond repair, just throw them away or strip them down to the wire for salvage.
