What is a battery group size?
The Battery Council International (BCI) group size is a standard that defines a battery's physical dimensions, terminal type, and terminal position - so you know it will physically fit your tray and connect correctly. There are only about 30 common passenger-vehicle group sizes. Matching the group size (and meeting the CCA rating) is what makes a replacement "fit."
