What parts do I need for a battery cable replacement and how much do they cost?

Check with your owner’s manual or mechanic for the exact parts you’ll need, but in general, here’s a breakdown of what you’ll need to replace your car’s battery cables:

Replacement battery cables: Battery cables allow the electrical current to flow to the alternator, powering electronic systems like the ignition system, the ECM (Electronic Control Module), and the lighting system. New cables have an average cost of about $15. We recommend reputable brands such as ACDelco, Deka, and Standard Motor Products for your replacement battery cables.

Basic tools: When removing the old battery cables, you’ll need some basic tools including a screwdriver, socket wrench, wrench, and ratchet. These can cost anywhere from $5 for a single tool to over $100 for a set. We recommend Craftsman, Tekton, and Kobalt for essential tools.

You may also want to purchase a wire brush to clean the car battery terminals before installing new car battery cables.

You can purchase battery cables, basic tools, and a wire brush at various places, including local auto parts stores like AutoZone and Advance Auto Parts, as well as online retailers like Amazon and Walmart.

Should I buy OEM or aftermarket parts?

When it comes to replacing your battery cables, aftermarket parts will do the trick. They’re widely available from numerous retailers and are often significantly cheaper than buying OEM parts.

Where can I buy parts for my battery replacement?

You can purchase battery cables through many online auto parts stores like AutoZone. You can also find them on Amazon. Check your vehicle’s owner's manual for the specifics of your battery cables.

How will a mechanic replace my battery cables?

Replacing the battery cables is a simple process. Here are the steps your mechanic will follow:

With your car’s engine off, your mechanic will disconnect the negative battery cable and then the positive battery cable.

The mechanic will inspect your car’s battery, terminals, and cables for corrosion and wear and tear before being cleaned and repaired.

Then, they will reconnect and test the battery to ensure its output matches your vehicle model’s specifications.

What happens if I don’t replace my battery cables?

Your car needs its battery and cables to function correctly. The battery is responsible for powering up every electrical system in your vehicle. If the cables are corroded and malfunctioning, power can’t get to the rest of your car.

What are battery cables?

The battery in a vehicle is designed to power all the electrical components in your car—but that battery can’t work correctly without battery cables. Think of your car battery like a heart. The cables are blood vessels running an electrical current to the alternator, which powers all electronic systems.

As with any other part of your car, the components of your battery system will wear over time and begin to malfunction. In most cases, the battery cables start to corrode and interfere with the electrical system. This can lead to malfunction in several parts of your car.

How do I know when my battery cables need replacing?

There are a few telltale signs that your battery and/or its cables will need to be checked out by a mechanic. Here are the most common symptoms to watch for:

Trouble starting your car’s engine

A clicking sound when trying to start your engine

Corrosion deposits on the battery itself

Battery cables show signs of wear and tear, such as fraying or loosening

Interior lighting dimming

Engine stalling after startup if your car doesn’t get moving

Remember: Everything runs off your car battery and the battery cables—so if the cable is worn and the electrical current isn’t being transferred to the alternator, your electrical systems won’t work correctly.

How often should battery cables be replaced?

Battery cables will usually last anywhere from 50,000 to 100,000 miles. Based on an average mileage of 14,000 miles per year, they may need to be replaced every 3.5 and 7 years. But don’t rush into changing them if they don’t show signs of wear and tear.

Battery cables are constantly used, which means wear and tear can result in corrosion, overheating, or insulation perishing.

If the battery light is flashing but nothing is wrong with the battery, it could also indicate that the cables need replacing.

Can I replace my battery cables myself?

Replacing your battery cables is a straightforward process that you can easily do at home, even if you don’t have extensive automotive repair knowledge.

This process is as easy as removing the negative and positive terminals and cable terminals, removing the battery, disconnecting the cables, and reinstalling new cables.

FAQs

Are battery cables easy to replace?

Changing the battery cables is a quick process for most vehicles, requiring only a few basic hand tools. It’s as simple as disconnecting the terminals, removing the batteries, then removing the cables before replacing them with new ones.

How long does it take to replace battery cables?

If you’re having a professional change your battery cables—or your car still has a dealership warranty—they can finish the job in about an hour. If you’re changing them yourself, the process may take a bit longer.

What happens if your battery cables are bad?

If your battery cables are bad, your car won’t start. Corroded or damaged battery cables prevent power from reaching the starter, resulting in an engine that won’t crank. You’ll also have no electrical power since bad battery cables isolate the battery from the car’s electrical system, preventing the lights and accessories from working properly.

Can a loose battery cable drain the battery?

Yes, the battery cables are designed to complete the electrical circuit. A loose or corroded battery cable can interfere with the battery charging system and lead to a dead battery. Corrosion can also build up between the battery post and cable, causing electrical resistance.
