Types of Car Battery Terminals: Top Post and Side Post Terminals

Top Post Terminals

Top post terminals are the most common type of battery terminal found in most cars. As the name suggests, these terminals are located on the top of the battery and usually feature a round post that is either positive or negative in charge. In most cases, the positive post is slightly larger than the negative post to make it easier to connect the cables.

Top post terminals are often used in newer cars. They are more stable and secure than side post terminals and are preferred by mechanics for their ease of use and accessibility. These terminals are usually made of lead or solid copper and are known for their durability and longevity.

Side Post Terminals

Side post terminals are less common than top post terminals and are usually found in older cars. These terminals are located on the side of the battery and often feature multiple bolts or screws that can be used to connect the cables. The cables are clamped onto the bolts or screws, making these terminals less stable and secure for the battery.

While side post terminals are less convenient than top post terminals, they are still used in some cars today. Some mechanics prefer side post terminals because they offer greater accessibility to the battery and are easier to install and remove. These terminals are usually made of lead or solid copper and are known for their durability and longevity.

In summary, both top post and side post terminals are used in car batteries. Top post terminals are more common and offer greater stability and security, while side post terminals are less convenient but still used in some cars today.

How to Measure Car Battery Terminal Sizes: Step-by-Step Guide
