Batteries are classified into numbered group sizes according to their voltage, maximum overall dimensions, terminal arrangement, and special features that may affect battery fit.
What identifies a battery as a certain group size?
There are four characteristics that identify a battery as a certain group size. The first is the size of the battery, and more specifically the dimensions. Batteries within a certain group size must be the same physical size (i.e., within 2mm) in order to ensure the proper fitment in a vehicle.
How are batteries categorized?
Batteries are categorized into groups based on their physical dimensions by the Battery Council International (BCI). Both inches and millimeters are used to categorize the length, width, height of the dimensions.
What is a battery size chart?
The size chart indicates the battery polarity and dimensions such as width, height, and length. Every number on the chart corresponds to a size set. This article explores various aspects of the battery size chart and a guide to choosing the best battery size for your applications.
The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. [ 1 ]
Here's a chart indicating the most popular battery group sizes and their dimensions. Group 24: Suitable for smaller cars and middle-sized sedans. Group 35: The batteries are commonly used for sedans, compact-sized cars, and light trucks. Group (H6) 48: This category of batteries is recommended for SUVS, large sedans, and trucks.
What is the most common battery group classification system?
Although BCI is the most common battery group classification system in the United States, others do exist. EN and DIN are other battery group classification systems that you will sometimes see in owner's manuals or when shopping for batteries.
