Sep 15, 2020   Pageview:32

A car’s engine consists of many parts. Some of the examples of those parts are wires, batteries, belts, and many more. The battery terminal connector is one of the car engine’s part also. Although they are small, the battery terminal connector plays a significant role in keeping the balance of the car’s engine. In this article, we will discuss the basics regarding the battery terminal connector, from its introductions, types, and how to connect them properly.

What are the best battery terminal connectors?

To understand why it’s necessary to have the best battery terminal connectors for our batteries, let’s talk about what it is first. Battery terminal connectors are the connectors that connect 12 volts or 24 volts cables to the batteries or the battery bank. Usually, the battery is a lead-acid battery.

There is no such thing as the best battery terminal connector. Everything depends on your environment. So first, you need to recognize what kind of environment you live in. only after that then you can decide which battery terminal connector suits you best.

What are the different types of battery terminal connector?

If you come across battery terminal connectors, you will realize that there are different kinds of battery terminal connectors available. Of course, they’re not without reason. The different connectors are created for the most suitable environment they can be used. Yes, connectors used in marine and land are different.

Here are the different types of battery terminal connectors available for you:

Brass Battery Terminals

If you live in an environment where your metal can get corrosion easily, then the most suitable battery terminal connector for you is a brass battery terminal. This terminal made from brass and tin plating. What makes them great is the fact that they are low in resistance and have a large amount of strength, so there is no need to worry when it comes to conducting a current. They can be soldered easily too!

Lead Battery Terminals

As the name states, lead batter terminals are terminals made of lead. What makes it special is the antimony that made up the lead, making sure that the terminal will able to survive in the tough world of electrical demand.

There are two kinds of lead battery terminals. The first kind is the normal lead battery terminal, the second one is the wing-nut and the ordinance type is the last lead battery terminal. wing -nut is the terminal that uses a compression plate in order to attach the cable properly. Meanwhile, the ordinance type is the terminal that uses a ring lung to connect the battery. What makes ordinance type different is how it can attach many wires or cables at the same time.


Of course, the lead battery terminal you can use depends on your needs. If your battery is less than 2 AWG, then it’s ok to use a normal lead terminal. However, if it’s beyond 2 AWG, then it’s best to use wing-nut or ordinance type.

Copper Battery Terminals

If you need a battery terminal that gives strength, conducts easily, and can be smoldered in a snap, then look no more because the copper battery terminal is the right terminal for you. Copper battery terminals have all the right properties to be used for many environments (though for humid it’s still best to use lead battery terminals).

There are four different kinds of copper battery terminals. They are right angle, straight barrel, parallel, and left angle. The different kinds are made in order to connect many batteries all at once to the battery bank.

special battery Terminals

Special battery terminals are terminals that are made for specific purposes, such as television whatsoever. The most common special battery terminals are the ones that are specially made for audio and power distribution. They are usually stylish and colored brightly so that they can bring some fashion sense into the object. They also give access to many connections so that the person can plug many cables all at once.

From the description above, we can see that each battery terminal is different and is emphasized for different purposes and environments. The best thing to do before purchasing a battery terminal is to make sure that you actually know which battery you really need.

What battery terminal connect first?

Despite its tiny size, the battery terminal plays a big role in connecting the cable volts to the battery bank. Because of that, it is necessary to use the proper steps to connect the battery terminal to the battery banks. Here are the steps to do it:

1. Prepare Yourself

The first thing you want to do is prepare yourselves for the process. It’s best for you to wear latex gloves, safety glasses, and boots to prepare for the worst-case scenario. You don’t know what will happen later on.

2. Prepare Your Car

Next, you should check on your car. Make sure that the car is off. For extra safety measurements, you can hide your key so that nobody would start the car without you knowing it first. Putting the car in park brake mode also helps for extra security.

3. Find the Positive and Negative of the Battery

After checking the car, it’s time to go to the car battery. Find the car battery and make sure that you recognize the positive and negative sides properly. The different sides usually have different colors or specific signs that tell which side is what.

4. Plug Wires to the Battery Terminals

Unwrap the wires and plug them to the battery terminals. Make sure there no plastic whatsoever that sticks to it.

5. Positive and Negative Wires

Connect the positive wire to the starter by using bolts so ensure maximum attachment. It’s best to use a clean new blot to avoid and dirt on it.

After that, attach the negative wire to the engine block or the car’s body. Again, use bolts to attach the wire to the hole.

6. Rush Car

Recheck everything to make sure that everything is tight and properly set. Then, rush the car.

We hope the information we provide can help you understand more about battery terminal connectors. Good luck at finding the right battery terminal for your needs!
