Battery group size refers to the physical dimensions of a battery. It is a standardized system established by the Battery Council International (BCI) that assigns a group number to batteries based on their size and capacity. This system ensures that batteries of the same group size will fit into the same battery tray.
You are probably familiar with the most common batteries for many different types of household appliances and devices, such as A, AA, AAA, D and E. However, when you need to power larger devices or vehicles, you’ll need to consider one of the larger battery groups, such as groups 24, 27, 31, and so on. Suppose you need a replacement battery.
Several factors influence the determination of a battery’s group size: Automotive manufacturers typically specify a particular group size for each vehicle model. They consider factors such as available space within the vehicle, required cranking power, and electrical demands.
The group number on a battery provides information about its physical dimensions and polarity. This information is important when selecting a battery that will fit properly in your vehicle. How do I determine the correct battery group size for my vehicle?
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.
These include GC8, GC8H, and GC12 battery groups. Group 24 is the most popular for marine purposes. They are lead-acid batteries and typically have a 75-85 amp-hour capacity, 500-840 cold-cranking amps, and a reserve of 140-180 minutes. Other popular marine battery groups include 4D, 8D, 27, 31, and 34.
