Battery Cables: Car Battery Cables GM OE | ACDelco

ACDelco GM Original Equipment Battery Cables are high-quality copper electric cables that connect the vehicle battery to the electrical system. The battery cables have cast-lead terminal connections at the battery end of the cables. The battery cables carry the electrical current to and from the battery during starting and charging. These Original Equipment Battery Cables have been manufactured to fit your specific GM vehicle, providing the same performance, durability and service life you expect from General Motors.


  • Include factory-crimped copper alloy cable terminals to ensure electrical connectivity and durability not found with emergency-type bolt-on or spliced battery cable terminals
  • Features durable outside insulation to help protect the copper cable from severe under-hood conditions, such as oil, acid, heat, ozone and road splash
  • Meets SAE J1127 requirements and is rated for continuous use at temperatures up to 257 degrees Fahrenheit (125 degrees Celsius) for safety and dependability
  • Common strand size provides high “strand count” to improve conductor flexibility
  • Steel skeleton embedded in casting for more reliable electrical connection
  • Casting overlaps cable insulation to protect cable from corrosion, which is the primary cause of cable failure
  • GM-recommended replacement part for your GM vehicle's original factory component
  • Offering the quality, reliability and durability of GM OE
  • Manufactured to GM OE specification for fit, form and function



Did You Know?

Most vehicle breakdowns are due to one of five causes:

  • Out of gas.
  • Stalled/engine won’t start.
  • Dead battery.
  • Flat tire.
  • Overheated engine.

Most of these breakdowns can be avoided through the following measures:

  1. Periodic mechanical checkups, especially when engine stalling, hard starting or other such symptoms are signaling trouble.
  2. Regular tire inspection to spot damage, unusual wear or underinflation that can lead to the failure.
  3. Seasonal checks and preventive maintenance of the cooling system, a frequent factor in roadside breakdowns.
  4. Be sure the gas cap is on tight after filling up to safeguard against condensation in the tank. If moisture in the gas line freezes, the engine can stall.

Also, having a cellular phone or portable CB radio is of great benefit while traveling.

What It Does:

The Starting and Charging System starts the engine, maintains the battery’s charge and provides power to the electrical accessories while the engine is running.

Signs of Wear & Troubleshooting:

Signs that your battery cables might need to be replaced or are failing include:

  • Breaks or tears in the casing lining around the wires.
  • Resistance when bent –corrosive acid inside of the plastic sheeting will make it difficult to bend the cables.
  • White powder or a green tint to the copper wires, indicating corrosion.


Good Maintenance Practices:

  • Inspect the battery cables and posts for good connections and/or signs of corrosion. Clean them if needed. When working around a battery, always make sure to take the appropriate safety precautions.
  • WARNING: Battery posts, terminals and related accessories contain lead, lead compounds and cadmium chemicals known to the state of California to cause cancer and reproductive harm. Wash hands after handling!
  • Terminal Installation:
    • Step 1: Align the terminal and pull the wire from the back of the connector in order to seat the terminal.
    • Step 2: If necessary, cut the new wire to proper length and splice with existing circuit.
    • Step 3: If the connector is outside of the passenger compartment, apply dielectric grease to the connector.
    • Step 4: Install the TPA, CPA and/or the secondary locks.



What are other common types of automotive wires and cables?

  • Spark plug wire sets, battery cables and pigtail connectors

What are some specifications and standards should I consider when choosing an automotive cable?

  • You should always look for the Original Equipment Cable or one that is designed to the original fit, formand function.

Should I replace my battery cables when I get a new battery?

  • Not always. Battery cables should be inspected and changed if damaged or excessive corrosion is found.

Is the length of the wire or cable important for insulation or performance?

  • Yes, you should only use the wire or cable that is designed to meet the Original Equipment fit, form and function.
