Find a Replacement Battery

What is a BCI Group Number?

Commercially manufactured batteries adhear to a size standard called the BCI Group Number set forth by the Battery Council International. The BCI number refers to the physical dimensions of the battery and not the Amp Hours (AH) capacity. Although, there is a correlation between the battery case size an AH rating. Generally speaking the larger the battery the more the capacity.
