Standard BCI Automotive Battery Sizes |
Standard battery size groups are established by the BCI. When searching for a battery to fit the best way is to measure the space you have and then compare to this chart to get the Group Size number. Then when you go to the store to purchase the battery ask for the group number. This saves the headache of having to deal with the counter salesperson who gives you a blank stare when you tell it's for a "Lotus".
