battery cable is too short to reach battery connection. Had to replace the connection because it broke off and now cable to short

Had to replace battery/cable connection because it broke off, To add new connector had to cut off the end of the cable and now its approx 1/2" to short to reach the battery
Experienced mechanics share their insights in answering this question :
You can purchase battery terminal ends with cables attached at most automotive part stores. You want to find the same gauge/thickness of wire or slightly larger.

Then you’ll need a lug or crimp fitting that matches the size of the cables to attach them together and a pair of heavy duty crimping pliers.

Another alternative is going to the dealer and trying to find a new harness.

If you feel like you need assistance with this, feel free to contact a certified mechanic who can help you with any of your battery needs.

How to Identify and Fix Common car Problems ?

If wires are undersized, they can get so hot that the casing melts and can cause a fire. Fires are much more catastrophic than too much voltage drop and are the main risk in choosing too small of a battery cable.
If the connection isn`t strong, you wont be able to start your car. If starting your car results in a delayed start or no start at all, it might be loose battery terminals. Check your connections to ensure you cant wiggle or shift any of the cables, terminals, or the battery itself.
Choosing the correct size (diameter) and length of cable is important for overall efficiency. Cables that are too small or unnecessarily long will result in power loss and increased resistance. When connecting batteries in series, parallel or series/parallel the cables between each battery should be of equal length.
A loose battery cable can cause excessive resistance to build up which can cause issues with the electrical system in your car. You can have issues with your battery not charging all the way, problems starting your car, and dim headlights.
Take the plug end of your extension cable and screw it into the coupler by twisting it clockwise. Continue turning the cord until it won`t move any further. If you have a coupler with flat sides around the rim of the connection, use a wrench to twist it into place. Plug in your extended cable and test the connection.
It`s time to consider a replacement scenario. You don`t have to toss out the battery and wires entirely, however. Replacing just the battery terminals is an option that truly invigorates the battery`s longevity.
While some parasitic drain is normal to keep these systems going, if an electrical problem is present due to poor wiring, faulty fuses, or poor connections, a parasitic drain can rise depleting the battery`s charge.
If you can`t access the negative terminal on the dead car, it`s not a problem. In fact, when jump starting a vehicle, experts recommend connecting the negative clamp to a metal ground instead of the negative terminal of the dead battery. Use an unpainted metal part of the engine block.
When a wire is too small for the amount of current flowing through it, the resistance to current flow generates heat. The wire begins to imitate the heating element in a toaster as the current flow increases. First the wire insulations melts, after which it can get hot enough to ignite any nearby flammable materials.
Wire size is another important factor in determining voltage drop. Larger wire sizes (those with a greater diameter) will have less voltage drop than smaller wire sizes of the same length.
Voltage drop occurs when the gauge of the wire from the power supply to the fixture is too small to carry the current necessary to power it. In some cases, this can cause your fixture to appear slightly dim or show colors that look somewhat “dirty”.

My battery cables are to short to reach the battery can I just add some wire or do I have to replace the whole thing
ANSWER : Hello. I would recommend purchasing and installing the correct length cables to avoid any potential connection issues when adding additional battery cable wire. As you may know, there are different thicknesses of electrical wire required for different loads of electricity to pass through them. Additionally, any time there is wire spliced together like this, you run the risk of connectivity issues. I would recommend purchasing the correct length cables to install.

Replaced my battery and replaced ends to the battery cables – does not want to start until I turn it over a few times – I think it my main cable.
ANSWER : Billing question sent to CS for the cost of replacing the positive (+) battery cable to a 1999 Dodge Ram 1500, along with the customer wanting to know where to go to install new seat belts.

Hooked up battery cables to wrong car when jumping it
ANSWER : You may have damaged the car you were jumping from. I have seen alternator, ECM, various relays, and fuses damaged from improper jumping. You should monitor the problem to see if it continues to get worse. If so, have a local expert inspect the clicking noise and pinpoint any appropriate repairs that should be made.

Car will not start, unless I move the battery cables. Replaced the terminals already.
ANSWER : If you can move the battery cables around to get your vehicle to start, the battery cables are likely the cause of the problem. Many times, older vehicles can get corrosion on metal parts. It is possible that the battery cables you have are either burned or filled with corrosion. I would recommend replacing all the cables that go from the battery and the vehicle should start right up. If you are in doubt about conducting this repair yourself, I would recommend having a professional, like one from YourMechanic, replace the battery cables for you.

in my car battery warning light appearing while driving.so I have replaced both battery and alternater still light is on
ANSWER : As you may yourself have seen, there are many reports of this fault with the Civic, that is a battery or alternator is replaced only to have the warning light fail to extinguish despite checking every conceivable electrical possibility. Your only recourse is to have a certified mechanic go through that exercise with your car and that involves first attempting to "re-set" the light. If the warning light returns, the alternator output has to be carefully measured both loaded and unloaded. All terminal connections have to be verified including all grounds. Fuses have to be checked for integrity (continuity) and the possibility of shorts, in for example dash wiring, has to be checked. To request this repair, simply request an electrical components diagnostic and the responding certified mechanic will seek a resolution to this.

Positive battery cable is corroded at junction point. Does the entire cable need to be replaced?
ANSWER : Hello,
Depending on how severe the corrosion is and whether the corrosion has caused any damage to the cable itself, it may or may not need to be replaced. Corrosion can cause very minor damage and can be easily removed with the right chemicals if it is detected early enough, however over a period of time, if this goes unnoticed, this can lead to further damage to connections on the cable resulting in faulty battery cable connections. I would suggest having a certified mechanic from YourMechanic come to your location to take a look at your car to provide a second opinion.

Battery light stays on and overnight battery drain. 2006 Land Rover LR3
ANSWER : Hi there – yes, something is going on here that’s draining your battery. Perhaps the pressure of the engine wash dislodged wiring which has shorted, or there was a chemical reaction to the cleaning solution that caused electrical damage in the alternator or voltage regulator. These componnents can be checked off of the vehicle. Vehicle wiring can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems. A professional mechanic, like YourMechanic, can come to your location, and perform this procedure for you, and replace/repair the failing component.
