Understanding Car Battery Sizes
A car battery size is typically denoted by a combination of letters and numbers, which can be confusing for those who are not familiar with the system. The most common battery size notation is the Group Size, which is a standardized system developed by the International Association of Automobile Manufacturers (IAAM). The Group Size is a combination of letters and numbers that indicate the battery’s physical dimensions, terminal configuration, and electrical capacity.
Group Size Notation
The Group Size notation typically consists of three letters and two numbers. The first letter indicates the battery’s physical dimensions, with “E” representing a small battery, “F” representing a medium battery, and “H” representing a large battery. The second letter indicates the terminal configuration, with “L” representing a side terminal and “R” representing a top terminal. The third letter indicates the battery’s electrical capacity, with “24” representing a 24-cell battery and “27” representing a 27-cell battery. The two numbers following the letters indicate the battery’s physical dimensions in inches.
| Letter | Meaning |
|---|---|
| E | Small battery |
| F | Medium battery |
| H | Large battery |
| L | Side terminal |
| R | Top terminal |
| 24 | 24-cell battery |
| 27 | 27-cell battery |
For example, a battery with the notation “H6-24L” would be a large battery with a side terminal and a 24-cell electrical capacity. The “6” in this notation indicates the battery’s physical dimensions, with 6 inches being the length and 5 inches being the width.
Reading Car Battery Size Labels
When reading a car battery size label, it is essential to pay attention to the Group Size notation, as well as the battery’s physical dimensions and terminal configuration. Here are some tips to help you read a car battery size label:
- Look for the Group Size notation: The Group Size notation is usually printed on the battery’s label or on the manufacturer’s website. It will typically consist of three letters and two numbers.
- Check the physical dimensions: The physical dimensions of the battery will be listed on the label or on the manufacturer’s website. These dimensions will indicate the battery’s length, width, and height.
- Check the terminal configuration: The terminal configuration will be indicated by the letter “L” or “R” on the Group Size notation. This will indicate whether the battery has a side terminal or a top terminal.
- Check the electrical capacity: The electrical capacity of the battery will be indicated by the number of cells, which will be listed on the label or on the manufacturer’s website.
