Replace the failed or corroded Battery Cables in your 2011-2016 Chevy/GMC 6.6L LML Duramax. Shop XDP for high-quality battery and alternator cables for your vehicle today! A common indicator of damaged or deteriorating battery cables is no power when you turn the key. The vehicle may not get any electrical power if the wires become damaged or do not make a good connection with the battery. Although battery cables have a simple function, they are an essential part of your vehicle's electrical system. The battery cables are responsible for transferring energy from the battery to the rest of the electrical system. Starting a vehicle necessitates a significant amount of cranking force. The ability of the battery wires to conduct full power can be reduced substantially by damage or wear. It's a good idea to check your cables for symptoms of damage or severe corrosion on a regular basis. The terminals can weaken over time and develop cracks as the metal ages and after multiple battery changes.
