What does battery bci code 36R stand for?

The Battery Council International (BCI) created a "standard" auto / truck battery size system. I put quotes on "standard" because some European manufacturers don't adhere to BCI standards. The number represents the length, width and height of the battery. The battery's PHYSICAL size. It is very important to note that there can be a vast difference in the ELECTRICAL size of batteries in the same BCI group. The ELECTRICAL size is usually measured in Cold Cranking Amps (CCA) or Cranking Amps (CA) and reserve rating (the time the battery will keep a vehicle running without alternator assistance). Some Europen batteries are rated in Watts. Mark K Raleigh, NC
