The battery group size chart plays the most crucial in assisting vehicle ownership. BCI, or Battery Council International, sets the standard for battery weights, dimensions & testing procedures. The EN & DIN cross reference chart also assigns battery group size. Knowing the exact battery group size helps to find the new battery for replacement.
We all know batteries come in various shapes and sizes, but what does it mean when someone says a battery "group?" The simple answer is that in the world of car batteries, group means size. If that were also the case in the world of shoes, you would ask someone at Footlocker for a Group 11 Vans Old Skool.

Other examples include group U1, which are intended for utility vehicles, and Group GC8, which is designated for golf carts. It lists many different battery groups that are designated for automotive and light truck uses, which come in many different shapes and sizes. What if I Can’t Find The Right Battery for My Group?
A Group 27 battery is 12-volt and has 70 to 100 Amp-hours (Ah). Group 31 batteries can have up to 120 Ah or more. Using the BCI group size chart helps you find the right battery. It shows size, terminal type, and electrical specs for your car. This ensures a safe and proper battery replacement. Choosing the right car battery is important.
Typically, the group size is stamped on the battery case. The group size designation is important because it ensures that the battery you purchase will physically fit in your car. If you don’t consult a battery size chart, you might purchase a too small or too big battery for your car.
