Choosing the right battery cable size and length is important for your battery’s overall efficiency. In order to find the right battery wire gauge, you need to know the amperage that the accessory needs to carry and the wire length between the accessory and the power source. The higher the amperage, the larger the gauge. Before purchasing battery cables, it’s best to review your owner’s manual to see what gauge it recommends. At Canadian Tire, we offer battery cables in a range of gauge sizes and lengths to fit your vehicle’s needs.
Is there a difference between battery cables?
There are different types of battery cables that are used in specific applications, whether it’s for cars, trucks, RVs, or even marine applications. The main differences between the various battery wire types are the insulation, flexibility, and copper strand counts.
Do I hook up the positive or negative battery cable first?
When you’re connecting cables to a car battery, remember to attach the positive terminal first, then the negative terminal to the ground. For more information on the order in which to disconnect and reconnect battery terminals, see our guide on How to Install a Car Battery.
