You are here because you are looking for the best battery terminal to buy. Buying is easy but making a decision on what to buy is difficult. This article therefore will help you on how to choose the best battery terminal to buy for your car.

Basic understanding of battery terminals

As a car owner, you need to have a thorough understanding of the role of battery terminals. Thus, they are of immense importance when it comes to connecting or terminating the battery charge to the batteries. Therefore, in modern times, they are even used in electrical devices such as battery inverters.

First of all, it is important to check the connections of your battery terminals. Secondly, the loose connection may even prevent your car from not running or looking properly. So, a bad connection will make the battery life short, as well as electrical accidents like fire.

However, you cannot select the best battery terminal until you read the detailed reviews in this article. Still, there are plenty of battery terminals available for users, from which we have reviewed the best ones.

What is a battery terminal?

The terminal is a type of clamping device. Its purpose is to provide a solid electrical connection between the two ends of the wiring to each other or to a power source. In relation to automobiles, battery terminals are more frequently referred to.

They are made of metals with high current conductivity. The stability of the electronics depends on the quality of these elements. Due to constant exposure to moisture in the air, they can rust.

What are terminals and how to protect them from oxidation?

Types of terminals

The types of battery terminals depend on:

  • battery polarity;
  • installation diagrams;
  • compound forms;
  • fabrication material

Battery terminal brands

Dozens of brands compete with each other for customers’ money. They release hundreds of new battery terminals every year, which makes the variety of options really huge. If you don’t want to get lost, follow exactly what we outlined here below about the best battery terminals on the market.

Modern brands offer hundreds of various battery terminals. The number of options is outstanding, which makes the process of finding the best battery terminals very time-consuming. That’s why we want to help you: use our list of the best battery terminals on the market to make the right decision.

Battery polarity

Car batteries provide direct current. Therefore, when connecting an electrical circuit, it is extremely important to observe polarity. Contact “+” (positive) cannot be directly connected to “-” (negative)

In passenger car batteries, the contacts are on opposite sides of the case. Modifications for trucks are equipped with contacts on one side. All batteries differ in the arrangement of the output contacts.

  • Direct polarity. Such batteries are installed in domestic car brands. In them, the positive contact is on the left and the negative contact is on the right.
  • Reverse polarity. On foreign cars, an option with the reverse contact arrangement is used.

In some batteries, the terminals are connected diagonally. Clamping contacts can be flat or curved to one side (to avoid accidental contact). Pay attention to its shape when using a battery with limited space near the contacts.

Wiring diagram

The most common wiring diagram for the electrical system is from the top of the battery. To prevent the motorist from accidentally reversing polarity and ruining the equipment, the battery contacts have different diameters. In this case, when connecting the wires, the car owner will not even be able to put a terminal on the battery output contact.

When buying a car abroad, you need to make sure that the battery contains North American standards (and not Asian) standards. If the terminal of such a battery fails (rusts or breaks), it will be difficult to find a replacement and the battery will have to be replaced.

These types of batteries can be of different sizes and are therefore not suitable for installation in the engine compartment of the machine. Therefore, cars for the Asian market are not sold in North America and vice versa.

Forms and Dimensions

Before buying a new pair of terminals, you should pay attention to the shape of the battery contacts. Most automotive batteries sold in the CIS countries are equipped with cone-shaped contacts. Naturally, a flat terminal in this case will have a smaller contact area. As a result, an electrical circuit is broken due to an oxidized compound.

The contacts of some batteries have a bolt clamp (truck options) or a screw (common standard in North America). You should pay attention to this when buying a car on American Internet sites.

If it happened that a motorist bought a car with a non-standard battery connection, you can buy a special adapter for terminals or self-locking modifications.

Fabrication Material

There are four types of battery terminals.

  • Made of lead

The most common type of connector. They are equipped with a bolt clamp. The downside is that the material melts at a low heating temperature (327 degrees). However, in the event of a short circuit (if the wiring does not have time to burn out), it will act as a fuse. Such terminals are characterized by greater resistance when pressing contacts. Another downside is the lower conductivity compared to the copper and brass counterparts.

  • Made of copper

This type of clamp is rarely used in car batteries due to the high cost and long manufacturing process. Copper is an excellent conductor of electricity. It doesn’t rust that fast. It is worth considering that this category of terminals mistakenly includes copper-clad steel modifications.

  • Made of brass

This type of terminal has a high resistance to humidity, so oxidation is very slow. They are easy to install but easy to bend and break if you strain when tightening the bolts.

  • Made of bronze

The material is similar to brass, but it is more durable.

Which terminals to choose?

The easiest option is to buy the type of terminal that is installed in the car at the factory. In this case, there will be no installation problems.

If it is necessary to replace the standard terminals due to their impracticality, then it is better to stop at the main version. They will cost less and are better in strength than their bronze and brass counterparts.

Copper is an ideal choice because it oxidizes less and can be securely bolted. However, they are harder to find and cost much more.

How to prevent oxidation?

Regardless of the material, all terminals will sooner or later start to rust. This is a natural process when exposed to wet metal. Due to poor contact with the battery, sudden voltage spikes can occur in the electrical system of the machine (this effect occurs when the voltage is restored and is often accompanied by sparks).

To avoid expensive equipment malfunction, it is necessary to regularly maintain contacts at the terminals. To do this, periodically disconnect them and remove the plate inside the sockets. This procedure must be done, even if the car is in a dry garage because plaque formation can be due to a chemical reaction when parts are heated and exposed to electricity.

Some motorists perform this procedure by loosening the set screws a little and turning the terminal on the contact several times. These actions will help restore nutrition, but at the same time, the main elements will become unusable. It is much better to clean the contacts with alcohol wipes.

Conclusion

Therefore, battery terminals are a simple but important element in the electrical circuit of a car. With proper care and installation, they will ensure the stable operation of all electronics and electrical equipment. Failing to choose the best battery terminal for your can may result in unexpected breakdowns that could lead to higher maintenance costs especially in automatic transmission vehicles.
