1. What Gauge Is A Car Battery Cable?

As I mentioned earlier, a vehicle’s battery cable is one of the most crucial battery management system constituents. To avoid any starting problems or any sporadic electrical issues in your car, you have to pick an appropriately-sized car battery wire. Why is this important? If you choose an ill-sized wire gauge, you will create more problems instead of solving the existing ones.

For instance, an overly thick gauge often prevents proper current distribution, whereas an extremely thin gauge can short-circuit the engine. So, to evade such disruptive circumstances, you have to choose a cable whose size suits the specific vehicle’s electrical system. What is a cable gauge?  A gauge simply refers to a conductor wire size either in terms of its diameter or cross-sectional area. How do you choose the correct battery cable gauge?

First, you have to note that there different gauges. It would be best if you made a choice based on the prerequisites of your vehicle’s electrical system. Electrical systems tend to vary in terms of amperage, and the chosen gauge determines the amperage supplied by the wire.

For example, a 2 gauge battery cable is suitable for low voltage DC electrical systems. An attempt to use this type of cable in a high voltage system will result in a catastrophic engine failure. Thus, it would be best if you took your time and considered all possible options before selecting an appropriate product you want. The charts below will guide you in choosing the most suitable gauge for your car’s electrical system;

2. What Size Is The Standard Car Battery Cable?

Generally, vehicles have different types of battery cables and electrical systems. Thus, it is inappropriate to assume that there is one standard size of cord that suits all vehicles. However, car batteries generally operate with a 12-volt power supply. So, the question you should ask is which car battery cable size is suitable for a 12-volt power supply?

Ideally, a 6 gauge cable is the best option for a 12-volt power supply. This automotive wire can sustain a maximum of 60 volts and is ideal for 12-volt electrical systems. More importantly, it meets all requirements of the Society of Automotive Engineers (SAE) specification J-1127. Why is it important for any car battery cable? Well, it is a universally recognized quality indicator. How would you feel if somebody attempted to convince you to buy a product that doesn’t have a mark of quality? Any wise individual that values his money will always consider the quality rather than the car battery cable price. Therefore, you should always watch out for it.

3.Which Car Battery Cable To Connect First?

Maintenance-cognizant vehicle owners are aware of the fact that batteries have to be replaced from time to time. However, most people don’t know that connecting and disconnecting a battery cable is a systematic process. You can’t just attach or detach the negative and positive terminals haphazardly. Failure to follow the proper procedure during connection may result in a car battery explosion. Logically, nobody wants that to happen, mainly because car batteries are expensive. So, which car battery cable should you connect first to avoid any explosion?

It is always advisable to connect the positive cord before connecting the negative car battery cable. What would happen if you were to interchange the order of connections? Well, to put it simply, you may have to dig into your savings to purchase a new car battery. You have to work with a wrench when connecting a car battery power cable.

If you attach the negative cord first, there is a chance that the wrench will accidentally complete the circuit. When this happens, there is a significant chance that the battery will generate a dangerous spark. Consequently, you should always follow the correct procedure or seek expert assistance when connecting your car battery cable.

4.Which Battery Cable To Disconnect First?

As I explicitly mentioned above, the process of attaching and detaching a battery wire has to be methodical. Any haphazard connection or disconnection often results in dire consequences. You might end up with a blown battery or, in the worst-case scenario, a physical injury. Hence, which car battery cable should you disconnect first to be on the safe side?

It would be best if you always detached the negative cable first before disconnecting the positive cable. Otherwise, you might accidentally trigger a dangerous spark. How do you differentiate between a negative and a positive wire?  Well, it is pretty simple. The car battery red cable is always the positive cord, whereas the black one is negative. If you doubt your ability to disconnect the battery code, it would be best to seek an expert mechanic’s services.

5.How To Replace A Car Battery Cable?

As indicated earlier, there are several reasons why you might want to replace your battery cables. Corrosion and resistance build-up are the most common justifications for car battery cable replacement. Here is a step by step guide on how to replace your car battery cable;

• First, you need to scrutinize the battery components before you do anything.
• After locating the positive and negative terminals, detach the negative cable first
• Next, detach the positive cable and carefully eject the battery from the engine compartment.
• Once the battery is safely removed, trace back the cables to where they are connected to the car’s frame. Carefully disconnect both of them.
• Proceed to attach the replacement cables to the car frame and use both hands to put the battery back to its slot.
• Clean the battery’s terminals and reattach the positive and negative cables starting with the positive end. After that, test the car to ensure that the installation is working.
